On March 1 2006, US pharmaceutical company Pfizer sued the Philippine International Trading Corp (PITC) and the Bureau of Food And Drugs (BFAD) before the Regional Trial Court of Makati Branch 61. It accused them of infringing its patent for its anti-hypertension drug Norvasc (which has the generic name amlodipine besylate), after the PITC imported some samples of a similar drug sold by Pfizer in India (under the brand name Amlogard) and submitted the samples to the BFAD for testing and product registration. Pfizer's Philippine patent expires in June 2007. The PITC filed a Ps1.5 million ($30,000) countersuit against Pfizer, claiming that the US company was attempting to stop the government from importing cheap medicine.
