The Federal Institute for Drugs and Medical Devices said yesterday it had ordered drug manufacturers, wholesale dealers, medical stores and other outlets not to sell or use these medicines any longer.
It also suspended the marketing authorisation given to the drugs concerned based on the data of clinical trials supplied by the Hyderabad-based contract research company.
The regulator said it had informed the drugs manufacturers about its decision on Monday and the ban on the sales of medicines came into effect yesterday.
Patients still using these medicines have been advised to consult their doctors.
In a press statement, the regulator said it did not expect its ban to cause any shortage of supplies as similar generic versions of these medicines by other manufacturers as well as their original branded versions are available in the market.
So far, it has no information about any health risks for patients, who have been using the banned medicines.
In view of these "serious and systematic deficiencies", the bio-equivalence studies carried by the Indian company to establish that the generic versions have the same effect on the human body as the original branded versions, cannot be accepted as a basis for marketing approval, the statement said.
Media reports said earlier that the European Union's drug regulator the European Medicines Agency (EMA) believes that GVK Biosciences has been systematically manipulating its studies carried out on behalf of European drug manufacturers.
Among the 80 drugs banned by the watchdog, marketing authorisations were already withdrawn in the case of 17 medicines by five companies because the authorisation holders either asked for that or did not seek an extension, the statement said.
However, marketing authorisation of these drugs and the remaining 63 medicines by 11 companies will remain suspended until the authorisation holder submits the results of a new bio-equivalence study.
