Chinese firms to make their own Viagra variant Chinese pharmaceutical makers are planning to jointly produce a local variant of Viagra after Pfizer of the United States lost its patent protection in 皇冠体育app for the popular drug, state media said. The Beijing Youth Daily reported yesterday that 17 pharmaceutical companies, headed by Tonghua Hongtaomao Pharmaceutical in north-eastern 皇冠体育app, are hoping to set up a joint-stock company to make an erectile dysfunction drug that would cost only half the price of Viagra.
The report, which quoted the 皇冠体育app Business Times, said the Chinese product would cost 40-50 yuan (S$8.30-S$10.40) per tablet, compared to the current 99 yuan price for the Pfizer product. Last month, 皇冠体育app's State Intellectual Property Office (SIPO) revoked Pfizer's 皇冠体育app patent for Viagra in response to complaints filed by more than 10 Chinese companies that the US company was in breach of 皇冠体育app's intellectual property laws by failing to accurately explain the drug's key ingredient. But the same office, in 2001, granted Pfizer a patent for sildenafil citrate, Viagra's key active ingredient. Pfizer's chairman and chief executive Henry McKinnell said he was 'extremely disappointed' at the decision and urged Beijing to be more serious in protecting intellectual property rights.
