Inquirer – May 9, 2007
MANILA, Philippines -- A state-owned Philippine company on Tuesday urged regulators to cancel the patent held by pharmaceutical giant Pfizer on a popular anti-hypertension drug Norvasc.
Philippine International Trading Corp. (PITC) wants the Intellectual Property Office to cancel the US-based company's exclusive patents on amlodipine besylate, known as Norvasc, so Filipino pharmaceutical firms can import or produce cheaper alternatives.
The Philippine patent, granted in June 1990 and expiring next month, is held by its British unit, Pfizer Ltd. UK.
PITC argued that the patent for Norvasc was "neither new and novel nor non-inventive."
A Norvasc tablet costs about one dollar in the Philippines but only some 10 cents in India, PITC said on its website.
PITC says multinational drug companies control around 70 percent of the Philippines' pharmaceutical market.
