Issue

Three companies (Accel Pharma Inc., Mint Pharmaceuticals Inc., and Pharmascience Inc.) are recalling all lots listed in the Affected Products table (above) due to concerns about the integrity of tests that are used to show that their generic prescription drugs work the same as brand-name versions.

Health Canada's authorization of the affected products relied on the bioequivalence test data. Bioequivalence data is used to demonstrate that generic drugs are equivalent to their brand-name counterparts.

The bioequivalence tests were conducted by Synapse Labs Pvt. Ltd., a contract research organization in Pune, Maharashtra, India. An inspection by a member of the European Medicines Agency, a trusted regulatory partner, found that data produced by Synapse Labs can no longer be relied upon to show this bioequivalence. As a result, the affected products can no longer be considered safe and effective. At Health Canada's request, the companies have stopped sale and have recalled all lots of the affected products until they can provide additional information to demonstrate that the products are safe and effective.

Health Canada is monitoring the effectiveness of the recalls and will take appropriate and timely action if any new health risks are identified.

Additional information

Background

Accel-Ondansetron ODT is used to prevent nausea and vomiting related to chemotherapy in patients 4 years of age and older, radiotherapy in adults 18 years of age and older, and after surgery in adults 18 to 64 years of age. Receiving too little ondansetron could lead to reduced efficacy (i.e., increased risk of nausea and vomiting). Severe cases can lead to dehydration, loss of appetite, malnutrition, electrolyte imbalances, weight loss and fatigue. If used after surgery, severe nausea and vomiting might lead to complications such as wound opening and infection. Receiving too much ondansetron could lead to serotonin syndrome, a serious drug reaction caused by medications that build up high levels of serotonin in the body. Symptoms of serotonin syndrome can be mild, such as shivering and diarrhea, or severe, such as seizures, muscle rigidity and fever, and changes in heart rate and blood pressure. Too much ondansetron can affect heart rhythm and lead to sudden cardiac arrest. The heart-related effects and serotonin syndrome can both be fatal if untreated.

Mint-Betahistine is used for reducing the episodes of recurrent vertigo (dizziness) associated with Ménière's disease in adults 18 years of age and older. Receiving too little betahistine could lead to reduced efficacy and inadequate disease treatment. Unexpected vertigo episodes can lead to accidents and injuries, which can have serious consequences. Receiving too much betahistine could lead to headaches, nausea, and upset stomach.

PMS-Pirfenidone is used to treat a serious, long-term lung disease known as idiopathic pulmonary fibrosis (IPF) in adults 18 years of age and older. Receiving too little pirfenidone could lead to reduced efficacy and inadequate disease treatment, resulting in worsening symptoms and disease progression. Receiving too much pirfenidone can lead to nausea, diarrhea, upset stomach, abdominal pain, decreased appetite, dizziness, headache, photosensitivity (sun) reaction and rash. It can also lead to drug-induced liver injury. Signs of liver injury include yellow skin or eyes (jaundice).
