Topic: How Long Does It Take For Invokana To Work
Within the first week of taking Invokana, your blood glucose levels should start to fall (generic name: canagliflozin). If you have concerns about your blood sugar levels, consult your doctor.
To regulate blood glucose (sugar) in adults with type 2 diabetes, Invokana is taken long-term with diet and exercise. It is commonly taken as a 100 mg or 300 mg oral pill once daily before breakfast. It is frequently taken with other glucose-lowering medications like metformin.
Invokana reduces blood glucose levels by decreasing glucose reabsorption by the kidney and increasing glucose excretion through the urine.
Invokana started lowering plasma glucose (blood sugar) after the first dose in the manufacturer’s studies. The drop in blood sugar is dose-dependent, meaning higher dosages cause a more significant drop. Increased urine glucose excretion was reported in patients with type 2 diabetes given 100-300 mg once daily for 16 days.
“Steady-state” was achieved after 4–5 days of daily Invokana 100 mg–300 mg dose. A steady-state is when the medication concentration in the body remains constant. In other words, a steady-state occurs when medication intake equals drug elimination.
Clinical success with Invokana varies from person to person. It may take longer depending on factors including age, weight, body fluid, extra drugs, renal or liver function or other medical issues. Your doctor is the best person to assess your overall reaction to Invokana.
What was Invokana approved for?
Invokana is an SGLT-2 inhibitor. It inhibits the kidney’s ability to reabsorb sugar (glucose), causing more glucose to be discharged into the urine. This lowers blood sugar and A1C.
The FDA approved Janssen’s Invokana in March 2013 as an oral diabetes medicine for individuals with type 2 diabetes. It is used along with a healthy diet and exercise. Its safety and efficacy were studied in nine clinical trials involving over 10,000 diabetics.
It is also licenced to reduce the risk of death in people with type 2 diabetes who have heart or blood vessel problems.
Invokana can lower the risk of end-stage renal disease, heart-related death, and hospitalisation for heart failure in people with diabetic kidney disease (nephropathy).
An A1C goal of 7 can be achieved with Invokana with other medications like metformin.
SGLT-2 inhibitors include empagliflozin (Jardiance), dapagliflozin (Farxiga), and ertugliflozin (Steglatro). These drugs are available singly or in combination with metformin.
Clinical study length
Type 2 diabetes is a chronic illness. To fully benefit from Invokana’s heart and kidney benefits, you must take it long-term. Your doctor may combine Invokana with other diabetic medications for further heart or kidney benefits.
Compared to an inactive placebo, both the 100 mg and 300 mg once daily doses of Invokana resulted in significant decreases in blood glucose (A1C) to less than 7%. The percentage of patients with A1C 7% was similarly higher than placebo. Weight and blood pressure reductions were also noted. Invokana with metformin or metformin + sitagliptin produced similar outcomes (Januvia).
The studies on cardiovascular outcomes (heart attack, stroke, or death) lasted even longer (2.8 years).
Do not stop taking your medication or change your dose without consulting your doctor.
Can Invokana be affected by medication interactions?
Using Invokana with some medicines that cause UGT enzymes may reduce its effectiveness in treating diabetes. Taking Invokana alongside these medicines may induce blood sugar spikes.
If you take rifampin, phenytoin, phenobarbital, or ritonavir, your doctor may need to raise your Invokana dose. This depends on your renal function.
Inform your doctor and pharmacist about all medications you take, including OTC, vitamins, herbs, and dietary supplements. Stopping any medicine without consulting your doctor is risky.
Invokana drug interactions can be discussed with your doctor or pharmacist.
Invokana works quickly, and blood sugar levels should fall within a week or two after starting this medicine. But each patient’s reaction is unique. Contact your doctor if you have concerns about your blood sugar levels.
Because drug interactions might alter Invokana levels in the blood, it’s critical to inform your doctor and pharmacist about all medications you use, including OTC and herbal remedies.
Type 2 diabetes is a chronic disease that requires lifelong medication. The benefits to your heart and kidneys are long-term, so it’s critical to keep taking your prescription as directed. Stopping or adjusting your medications without consulting your doctor is risky.
Concerning the Diabetes Drug Invokona
Invokana, approved by the US Food and Drug Administration (FDA) in 2013, belongs to a kind of Type 2 diabetes medication known as sodium-glucose cotransporter-2 (SGLT-2) inhibitors.
In humans, SGLT-2 is a protein that enables glucose reabsorption in the kidneys, and SGLT-2 inhibitors limit glucose reabsorption in the kidneys, increasing glucose excretion and, as a result, lowering blood glucose levels. Adults with Type 2 diabetes are often treated with SGLT-2 inhibitors.
Invokana and other SGLT-2 medications, such as Jardiance and Farxiga, have been demonstrated in studies and trials to be particularly helpful in managing blood glucose levels and reducing haemoglobin levels in Type 2 diabetic patients.
Invokana’s popularity has grown steadily since its debut to the market, owing to its efficacy. Invokana is widely regarded as the most popular medicine in its class.
However, Invokana and other comparable drugs have been associated with severe and potentially fatal side effects.
Invokana-Related Adverse Reactions
Invokana, while its outstanding ability to manage blood sugar levels, has specific potentially dangerous side effects:
Amputation Risk with Invokana
Clinical investigations have revealed that Invokana users are twice as likely as placebo individuals to require lower limb amputation. The hazards are much higher for those who have already had an amputation.
Invokana users should be on the lookout for indicators such as infections in the lower limbs, tenderness, and sores. If you notice any of these symptoms, contact your doctor immediately.
Ketoacidosis Risk with Invokana
Ketoacidosis occurs when the body is unable to produce enough insulin. When there is insufficient insulin, the body breaks down fat as an alternative energy source, resulting in a buildup of harmful acids in the bloodstream known as ketones.
Excess ketones in the blood, if left untreated, cause ketoacidosis, which can lead to diabetic coma, hospitalisation, and death.
Invoke Gangrene Risk by Invokana Fournier
The negative effect of SGLT-2 inhibitors, a life-threatening, flesh-eating bacterial infection of the skin, can be fatal if not treated immediately. Men are at a higher risk of contracting the virus.
In 2015, the FDA began issuing a series of public safety alerts warning the public about the links between Invokana/SGLT-2s and these severe side effects.
On Behalf of Injured Patients, Invokana Lawsuit Is Filed
A group of patients has launched an Invokana lawsuit against the maker, Janssen Pharmaceuticals, a Johnson & Johnson subsidiary.
How Can I Get Involved in an Invokana Lawsuit?
Suppose you or a loved one took Invokana (or a similar SGLT-2) to treat Type 2 diabetes and incurred injuries due to the medicine. In that case, you might be able to seek compensation for your losses through a Type 2 diabetes lawsuit.
TorHoerman Law is currently taking clients who used SGLT-2 inhibitors and incurred the following injuries:
Contact an expert Invokana lawyer at TorHoerman Law now to discuss your legal options.
Invokana and other SGLT2 inhibitors have been used at an increasing rate since 2013. During 2014, Invokana’s sales were $586 million, and during 2015, they were $1.3 billion. Despite the FDA’s approval of two competitive SGLT2 inhibitors, Jardiance and Farxiga, in 2014, Invokana’s sales were huge.
Janssen also gained permission for two new canagliflozin formulations.
The FDA approved Invokamet in 2014, and its extended-release form, Invokamet XR, was approved in 2016.
Since Invokana and other SGLT2 inhibitors were initially approved, millions of individuals have been prescribed them.
While sales have fallen in recent years due to side effects, Invokana still generates hundreds of millions of dollars for Johnson & Johnson.
SGLT2 inhibitors have also been related to diabetic ketoacidosis, a potentially fatal illness. The issue is usually connected with type 1 diabetes and arises when high amounts of ketones are in the blood due to fatty acid breakdown. When ketones accumulate in the body, they can be harmful.
All patients required emergency room visits or hospitalisation. The FDA has received further complaints of ketoacidosis since then.
The FDA published a safety communication7 in May 2015, warning that Invokana and other SGLT2 inhibitors could cause ketoacidosis.
Between March 2013 and June 2014, the FDA received 20 confirmed incidences of ketoacidosis in patients taking the class of medicines. All patients required emergency room visits or hospitalisation.
The FDA has received further complaints of ketoacidosis since then.
Labels were updated in December 2015 to include ketoacidosis warnings.
SGLT2 inhibitors may potentially increase acute renal damage. Between March 2013 and October 2015, the FDA received 73 confirmable cases of acute renal damage caused by Invokana, though the number could be higher.
In over half of the cases, the harm began within a month of starting the medications and ceased advancing soon after treatment ended.
Kidney damage can be severe and irreversible, thus in June 2016, the FDA strengthened8 current warnings on canagliflozin and dapagliflozin medication labels.
Urinary tract infections and yeast infections are two of the most common adverse effects in men and women. While these infections are usually treatable, persons taking SGLT2 inhibitors are more likely to have them again.
In some circumstances, severe urinary tract infections can progress to a potentially fatal blood infection known as urosepsis or a kidney infection known as pyelonephritis.
Dozens of individuals were admitted to the hospital for kidney failure caused by a urinary tract infection. In 2015, the FDA added warnings9 to labelling.
Hundreds of people file Invokana lawsuits.
Thousands of patients have been hospitalised or died across the country due to serious side effects that were not initially listed on Invokana warning labels. Victims have turned to the judicial system searching for compensation and justice since Janssen must warn consumers of potentially life-threatening dangers.
What exactly is the Invokana lawsuit?
Invokana is classified as an SGLT2 inhibitor. This medication is given to type 2 diabetic patients with blood sugar levels and poor glycaemic control.
Now that the FDA has released warnings regarding the kidney risks associated with Invokana, many people who are currently taking it are suing the manufacturer for a refund.
Many consumers are requesting refunds because they spent a lot of money on Invokana and were not informed about the kidney problems the drug can cause. The FDA has recommended against taking Invokana for persons with type 2 diabetes and high blood sugar levels in the complaint.
Instead, they have advised patients to try another medication, such as Jardiance, which the FDA claims has far less kidney harm and blood sugar-raising adverse affects.
The FDA’s advisory
In January 2016, the FDA issued a warning to clinicians regarding the drug’s adverse effects. According to the notice, “some Invokana patients have acquired serious, life-threatening renal issues.
” Kidney failure is one of these potentially fatal renal issues. According to the lawsuit, when Invokana is combined with other diabetic drugs, such as insulin or sulfonylureas, patients experience muscle weakness and protracted falls, resulting in severe damage or death.
According to the lawsuit, these kidney side effects were previously unknown. The FDA did not even consider them related to the medicine when it initially struck the market.
Commercial for the Invokana case
Pfizer looks to be using a lot of the negative publicity that Invokana has received in previous years to its advantage.
The commercial, which features individuals sitting in restrooms, outlines the history of Invokana and all of the adverse effects that have been reported since it was initially approved in 2013.
However, is it true that Invokana is the only anti-diabetic medication that causes renal problems? No, not exactly. The FDA has been aware of the kidney concern since 2012 when reports first surfaced.
Even before that, the medicine was being monitored by the FDA. However, it took another four years for Invokana to be approved for over-the-counter sales. Pfizer is looking for an easy way out to blame the FDA for the kidney problem. It also casts Pfizer in a bad light. However, this is not the case.
So, what should you do now?
Before you rush out to buy your next box of sugar pills, keep in mind that neither the Invokana advertising nor the medications themselves have been demonstrated to cause these adverse effects.
The FDA issued this caution partly because of the previous warning about kidney issues. Nonetheless, it’s always a good idea to do your homework and ensure you’re taking the proper drug for the right cause.
What are the potential negative effects of Invokana? The adverse effects can be extremely severe, and they are quite bothersome for some people.
Canagliflozin produce side effects?
In addition to their beneficial effects, most drugs can induce unpleasant side effects, albeit not everybody encounters these. Some of the most prevalent ones related to canagliflozin are listed in the table below.
A complete list can be found inside the manufacturer’s fact sheet that came with your medicine. Unwanted effects generally increase when your body adapts to the new medication, but visit your physician or chemist whether any of the preceding persist or become bothersome.
I am feeling thirsty and constipated.
Consume a very healthy diet and drink plenty of water every day.
Feeling ill (nausea)
Take your medications with a meal if possible. Inform your doctor if this is causing you any problems.
Important: On rare instances, canagliflozin therapy may cause an increase in the amounts of specific molecules called ketones in your blood. This can result in a dangerous disease known as diabetic ketoacidosis. If you experience any of the following symptoms, contact your doctor right away:
In rare cases, canagliflozin medication can result in a dangerous disease known as Fournier’s gangrene. Call your doctor right once if you experience any discomfort, tenderness, or swelling in the genital or perineal areas. The perineum is the skin that connects your genitals to your back passage (anus).
If you notice any other symptoms that you believe are related to this medication, consult your doctor or pharmacist.
Pregnancy Risks with Canagliflozin
According to animal studies, drug exposure during animal development phases matching to a late second or third trimester of human development resulted in higher kidneys masses and renal pelvic and tubular dilatation at dosages expected during human exposure.
The detected renal pelvic dilatations did not completely resolve after a one-month recovery. A sufficient number of randomised, double-blind, placebo-controlled trials in pregnant women are lacking.

News from the FDA Invokana labelling – the type 2 diabetes medicine now promotes cardiovascular health in people with type 2 diabetes with existing cardiovascular disease in addition to decreasing glucose levels.
The FDA has formally approved Invokana to reduce the risk of heart attack, stroke, and heart-related death in adults with type 2 diabetes and pre-existing heart disease. This is in addition to Invokana’s already approved “indication,” or use, for glucose reduction.
Invokana is a once-daily medication for people with type 2 diabetes; the new heart indication will benefit patients with diabetes and their healthcare providers, who will discuss Invokana’s heart benefits openly.
It will also apply to the Invokamet (canagliflozin/metformin) and Invokamet XR (canagliflozin/metformin extended-release) combo drugs.
Check out this discussion guide put together by the ADA and AHA for people interested in questioning their healthcare practitioner about how they may protect their heart health.
The CANVAS trial, which enrolled nearly 10,000 persons with type 2 diabetes who were at high risk of heart issues, found that using Invokana resulted in:
In contrast to Invokana, the FDA has approved many more type 2 diabetes drugs for heart protection.
Another SGLT-2 inhibitor, Jardiance, is approved to prevent heart-related mortality but not heart attacks or strokes. In contrast, a once-weekly injectable GLP-1 agonist, Victoza, is approved to provide the same heart-protective advantages as Invokana. SOURCE
People with Type 2 diabetes may have a variety of treatment options. Sometimes the doctor may suggest insulin injections, insulin pens for their patients. It’s indeed critical that you follow the instructions on the label.
All diabetes treatments have the potential to induce adverse effects. Before choosing the appropriate treatment strategy for them, patients should explore all alternatives with their doctor.
Alternatives to Invokana medicines include:
In addition to pharmaceutical treatment, some lifestyle changes should be implemented as part of any diabetes treatment plan.
The most basic advice is to eat a healthy diet. A well-balanced diet can assist patients in maintaining a healthy weight. It can also assist patients in better controlling their blood pressure, cholesterol, and blood glucose levels.
Doctors will almost certainly recommend exercise or regular physical activity as well.
J&J reports a successful Invokana trial.
After positive Phase III research findings were announced, the LoA for Johnson & Johnson’s Invokana (canagliflozin) increased heart failure. In systolic heart failure, the LoA increased by 16 points to 57 per cent, and in diastolic heart failure, it increased by 8 points to 33 per cent.
The Phase III Invokana research (NCT04252287) was revealed on November 14 at this year’s American Heart Association Scientific Sessions. On November 18, GlobalData assessed the medicine.
The primary outcome of the 476-person Phase III CHIEF-HF trial was changed from baseline in the Kansas City Cardiomyopathy Questionnaire Total Symptom Score (KCCQ-TSS). There was an improvement with Invokana at 12 weeks, with a mean difference of more than 4.3 points against placebo.
Invokana is an SGLT2 (sodium-glucose cotransporter 2) inhibitor. It is already approved by the FDA for type 2 diabetes, specifically for lowering blood sugar in adult patients, lowering the risk of significant cardiovascular events, and lowering the risk of end-stage kidney disease.
According to the company’s 2018 quarterly report, Johnson & Johnson is facing around 1,200 Invokana litigation. The majority of these cases were filed in federal district courts around the country, but several were also filed in state courts, especially in California, Pennsylvania, and New Jersey.
RARITAN, New Jersey, March 29, 2013 — Janssen Pharmaceuticals, Inc. announced today that the FDA had authorised INVOKANATM (canagliflozin) to treat adults with type 2 diabetes.
INVOKANATM is the first drug in a new family known as sodium-glucose co-transporter 2 (SGLT2) inhibitors to be licenced in the United States.
It is also the only oral, once-daily medicine licenced in the United States that has been shown in clinical trials to enhance glycemic control while also lowering body weight and systolic blood pressure.
Janssen Pharmaceuticals requested in October 2018 to settle many of the 1,100 Invokana claims filed against the firm. The Invokana settlement amount is confidential, according to a motion to establish a qualified settlement fund filed on October 16, 2018.
As of December 2018, the settlement’s complete terms were still being negotiated.
The dose of canagliflozin with metformin is tailored to the patient’s current diabetic medication regimen.
To decrease metformin-related gastrointestinal adverse effects, the combination of canagliflozin and metformin is given twice daily with meals, with gradual dose escalation.
In individuals with an estimated glomerular filtration rate (eGFR) of 60 mL/min/1.73 m2, the daily dose of metformin should not exceed 2000 mg. The daily dose of canagliflozin should not exceed 300 mg.
Canagliflozin 50 mg twice daily is the maximum dose for patients with an eGFR of 45 mL/min/1.73 m2 to 60 mL/min/1.73 m2.
Renal function should be evaluated before beginning treatment with canagliflozin and metformin.
10 If creatinine levels are 1.5 mg/dL for males or 1.4 mg/dL for females, or eGFR is 45 mL/min/1.73 m2, canagliflozin plus metformin should not be started or prolonged.
Canagliflozin plus metformin is available in four concentrations as film-coated tablets: canagliflozin 50 mg/metformin 500 mg, canagliflozin 50 mg/metformin 1000 mg, canagliflozin 150 mg/metformin 500 mg, and canagliflozin 150 mg/metformin 1000 mg.
Navigate to: Clinical Trials
Although no clinical effectiveness studies on canagliflozin plus metformin have been done, bioequivalence of canagliflozin plus metformin to canagliflozin and metformin coad ministered as separate tablets have been observed in healthy adults.
In type 2 diabetic patients, canagliflozin with metformin treatment resulted in clinically significant improvements in HbA1c levels compared to placebo. These reductions were observed across all subgroups, including age, gender, race, and baseline BMI.
Canagliflozin has been studied in conjunction with metformin alone, metformin and sulfonylurea, metformin and thiazolidinedione (i.e., pioglitazone), and metformin and insulin (with or without other antihyperglycemic agents).
Furthermore, canagliflozin’s efficacy was compared to that of a dipeptidyl peptidase-4 inhibitor (sitagliptin) and a sulfonylurea (glimepiride).
Canagliflozin is a Metformin Add-On
The efficacy and safety of canagliflozin in conjunction with metformin were assessed in a 26-week, double-blind, placebo-controlled phase 3 clinical trial.
This trial included 1284 individuals with type 2 diabetes who were not well managed with metformin alone (2000 mg daily or 1500 mg daily if a higher dose was not tolerated). The patients’ average age was 55 years, with 47 per cent men and an eGFR of 89 mL/min/1.73 m2 at baseline. 10
The primary end aim of this trial was the change in HbA1c levels from baseline after 26 weeks. The secondary end objectives were changes in HbA1c levels, fasting plasma glucose (FPG) levels after 52 weeks, body weight, and systolic blood pressure.
After completing a 2-week, single-blind, placebo run-in phase, 1009 patients already receiving the required metformin dose were randomised.
Furthermore, 275 patients receiving less than the needed metformin dose or metformin in conjunction with another antihyperglycemic drug were converted to metformin monotherapy for at least eight weeks before beginning the 2-week, single-blind, placebo run-in period.
Following the placebo run-in phase, all patients were randomly assigned to receive canagliflozin 100 mg, canagliflozin 300 mg, sitagliptin 100 mg, or placebo once daily as add-on medication to metformin.
Canagliflozin doses of 100 mg and 300 mg provided once daily as add-on therapy to metformin revealed a substantial improvement in HbA1c levels after the 26-week treatment period (P.001 for both doses) compared to placebo (Table 1).
Furthermore, when combined with metformin, canagliflozin 100 mg and canagliflozin 300 mg once daily, a higher proportion of patients achieving HbA1c levels of 7%, a significant reduction in FPG levels, improved postprandial glucose, and a more significant per cent bodyweight reduction compared to placebo.
The mean changes in systolic blood pressure from baseline were significant compared to placebo: 5.4 mm Hg for canagliflozin 100 mg and 6.6 mm Hg for canagliflozin 300 mg (P.001 for both doses).
Invokana has the potential to cause weight loss. It is approved to treat type 2 diabetes, although patients who use it may have some weight loss due to excess sugar being discharged through urination.
Invokana is available in dosages of 100 mg and 300 mg. In tests, patients lost weight on either dose of Invokana, although the higher 300 mg dose lost somewhat more.
Whether taken alone or in combination with standard diabetes drugs such as metformin and sulfonylureas, Invokana resulted in weight loss.
According to studies, those who take the 300 mg dose alone or in combination with other diabetic medications can lose 6-9 pounds in six months. People who took 300 mg of Invokana combined with metformin for a year shed a little more than 10 pounds.
In a year, people receiving the lower 100 mg dose of Invokana with metformin dropped roughly 9 pounds.
Invokana is a sodium-glucose cotransporter-2 (SGLT2) inhibitor that reduces blood sugar by excreting sugar through urination. While using Invokana, you may lose up to 100 g of sugar per day through urination.
It’s also vital to remember that Invokana has some dangerous adverse effects.
The medicine is linked to a twofold increase in the requirement for lower limb amputation. SGLT2 inhibitors have also been associated with an increased risk of developing necrotizing fasciitis of the perineum (Fournier’s gangrene), a rare genital illness.
Invokana users are also more likely than placebo users to suffer from bone fractures, kidney issues, diabetic ketoacidosis, and low blood sugar. Yeast infections, urinary tract infections, and increased urination are the most prevalent side effects.
NEW JERSEY’S RARITAN
The Johnson & Johnson drug safety team, gathered for an emergency meeting, offered a frightening picture: people taking the company’s new blockbuster diabetic treatment were becoming severely ill.
Invokana had been on the market for less than a year, and sales were fast approaching $1 billion. Senior executives listened in a small conference room on J&J’s campus here as safety specialists described a potential threat to the drug’s success.
Separate and surprisingly identical complaints received to the firm and obtained by Reuters described 18 people who became ill within days or weeks after taking Invokana due to a rare and potentially dangerous buildup of acid in the blood, known as diabetic ketoacidosis, or DKA.
At the March 2014 meeting, Dr Bruce Leslie, who led the safety team, advised that the corporation notify US and European regulators. “I think we should get ahead of this,” Leslie told executives in the room, according to a Reuters interview. “Otherwise, it may come back to bite us in the a$$.”
The executives were unconvinced. They decided to take no action.
According to corporate data examined by Reuters, by July 1 of that year, J&J had learnt of 39 cases of ketoacidosis. Nonetheless, the corporation remained silent.
It wasn’t until May 2015, two years and four million prescriptions after Invokana was introduced on the market that the public became aware of the drug’s link to ketoacidosis.
That’s when the United States Food and Drug Administration (FDA) opened an investigation after learning of an increase in the number of harmful occurrences through its reporting system. It and European regulators later demanded that a warning be included to the label of Invokana and other newer SGLT2 inhibitors.
The March 2014 meeting, which was initially reported here, was not a unique occasion. Based on interviews with several former J&J employees and a review of company documents related to Invokana’s development, rollout, and safety from 2010 to 2014.
Reuters discovered that J&J was regularly warned about the risk of ketoacidosis associated with Invokana over the five years before regulatory involvement, yet did nothing.
According to the records, J&J researchers discovered that certain patients had higher amounts of ketones, the chemical substances that, in high concentrations in the blood, can lead to ketoacidosis, as early as 2010, during the drug’s clinical trials.
Later, as the number of reported injuries grew, J&J management consistently disregarded internal safety concerns, putting doctors and patients in the dark about the health danger.
Leslie was told in a letter from his employer in the weeks following the March 2014 meeting that he could be dismissed for, among other things, participating in “an unduly acrimonious” conversation over Invokana.
A few weeks later, the Japanese business that created and licenced the medicine informed J&J that increased ketones were a potential concern.
The removal of the safety risk was a priority for the company, according to Leslie, because it was threatening sales.
He quit J&J some months after the meeting in 2014. He has not been involved in any legal proceedings with the corporation.
Dr Angelina Trujillo, a former J&J medical director who worked on Invokana, told Reuters that reports of patients getting ketoacidosis were “something the public needed to know.” J&J spent tens of millions of dollars marketing Invokana as a safe, effective medication for millions of individuals with type 2 diabetes.
Invokana is still on the market, with thousands of reports to the FDA of ketoacidosis and similar events tied to the medicine. However, sales have fallen as the drug’s label has been slathered with warnings about ketoacidosis and other potential side effects.
Nonetheless, J&J has earned more than $6 billion from Invokana since its introduction. And the drug is still making money: Invokana and a companion medicine brought in $795 million for J&J in 2020.
J&J defends their Invokana activities and the drug’s overall safety record.
According to Reuters, the business is “extremely concerned about the safety and well-being of patients treated with our products.” (The business) has worked hard and closely with regulatory authorities both before and after approval to monitor and examine emerging safety data
To report credible signals to FDA, and to warn healthcare professionals. Their patients of the risk-benefit profile for A request for an interview with representatives from Johnson & Johnson went unanswered.
Diabetes, as Reuters highlighted in earlier sections in this series, constitutes a substantial public health failure in the United States since the outlook for the growing number of individuals with the condition has deteriorated despite increased spending on innovative therapies.
Years of insufficient care left many of the millions of diabetics in the United States extremely vulnerable to the COVID-19 virus and the isolation of lockdown, leading to a disproportionate number of deaths and severe illness among those with the chronic disease.
Furthermore, drugmakers’ years-long marketing campaigns for an ambitious diabetes treatment goal – getting a blood glucose measure known as A1c below 7% – resulted in an epidemic of potentially fatal low blood sugar episodes.
Invokana, J&J’s first diabetic medicine, was marketed with that A1c treatment objective in mind. Invokana was launched in March 2013 amid an industry race to tap the rapidly expanding number of Americans with type 2 diabetes, who may represent a never-ending source of revenue.
Diabetes therapy spending was expanding at a double-digit yearly pace at the time, significantly outperforming the entire prescription drug market.
J&J made its position in this market with Invokana, defeating its competitors with the first SGLT2 inhibitor. J&J Chairman and CEO Alex Gorsky told investors in January 2014 that the 350 million individuals worldwide with type 2 diabetes represented a tremendous opportunity for the company.
In light of the estimates for the future and the unmet medical need in that region, Gorsky believes it is necessary to continue working there.
J&J positioned Invokana as the foundation of a new franchise. The drug was part of a larger strategy to achieve faster growth from prescription medications rather than relying on iconic consumer goods like Band-Aids and Baby Powder.
Farxiga vs Invokana
Invokana and Farxiga belong to the same drug class: sodium-glucose co-transporter 2 (SGLT-2) inhibitors. This means they treat type 2 diabetes in the same way.
Canagliflozin is the active ingredient in Invokana. Dapagliflozin is the active ingredient in Farxiga.
According to the FDA, the FDA has authorised the use of Invokana and Farxiga to lower blood sugar levels in people with type 2 diabetes.
Invokana has also been licenced to lower the risk of:
Farxiga has also been approved to lower the risk of:
Administration and drug forms
Both Invokana and Farxiga are available as pills taken by mouth first thing in the morning. Both medications can be taken with or without meals. However, Invokana should be taken before breakfast.
Risks and side effects
Invokana and Farxiga belong to the same pharmacological class and have similar effects on the body. As a result, they have highly comparable side effects. These are some instances of adverse effects.
Commoner side effects
These are some of the more prevalent adverse effects of Invokana, Farxiga, or both medicines (when taken individually).
Can happen with Invokana:
Severe side effects
These significant side effects can occur with Invokana, Farxiga, or both medications (when taken individually).
Can happen with Invokana:
Farxiga-related side effects include:
A few unusually severe adverse effects
This can happen with both Invokana and Farxiga:
In clinical trials, these medications have not been compared head-to-head. However, studies have shown that Invokana and Farxiga are adequate for their approved applications.
Invokana is a diabetes treatment that is taken orally. Canagliflozin is the active component.
Invokamet and Invokamet XR are medicines in the Invokana class. They are canagliflozin and metformin combo medications.
These pharmaceuticals are part of a larger class of sodium-glucose cotransporter 2 (SGLT2) inhibitors.
