OTTAWA – Health Canada is informing Canadians that Marcan Pharmaceuticals has recalled all lots of all MAR-Diltiazem CD products in response to data integrity concerns that could lead to incorrect dosing.
MAR-Diltiazem CD is used to treat chronic stable angina and mild to moderate hypertension. Receiving either too much or too little medication could lead to serious adverse health effects.
Health Canada’s authorization of Marcan’s MAR-Diltiazem CD relied on data generated by Panexcell Clinical Laboratories Priv. Ltd. An inspection of the Panexcell testing site by the European Medicines Agency (EMA), a trusted regulatory partner, raised concerns that the data submitted by the lab for bioequivalence studies of the MAR-Diltiazem CD capsules may have been falsified.
Bioequivalence studies are used to demonstrate that a generic drug produces the same amount of active ingredient in the blood as a brand-name drug. The active ingredient is the substance in the drug that treats illness.
Health Canada has reviewed additional evidence provided by Marcan and concluded that it does not sufficiently establish that the product is bioequivalent to the brand-name drug. As a result, MAR-Diltiazem CD cannot be considered safe and effective and therefore Marcan is not allowed to make any further sales until the company can provide additional information to demonstrate that the product is safe and effective.
What is Health Canada doing
In discussion with Health Canada, the company has initiated a stop sale and voluntary recall of the product until the company can provide additional information to demonstrate that the product is safe and effective.
Health Canada is monitoring the situation and will take appropriate and timely action if any new health risks are identified.
