According to reports, Natco had sent a notice to the US drugmaker in November 2010 saying Pfizer's drug was too expensive for HIV patients in India, and that Natco can sell its own product at about one-fifth the price. This is the first step in what is known in pharma industry as Compulsory Licensing (CL), a provision that allows generic drugmakers to make and sell low-cost version of a patented drug under certain conditions. Natco is the first company to initiate the process for CL in India.
Pfizer has time till May 2011 to reply. If it does not allow Natco to make cheap drugs, the Indian pharma company can approach the government for CL, that will allow it to sell a low priced version of the drug after paying royalty to Pfizer. As per reports, India has an estimated 2.3 million people living with HIV.
On a consolidated basis, Natco Pharma's net profit rose 10.8% to Rs 14.82 crore on 12% increase in net sales to Rs 120.05 crore in Q2 September 2010 over Q2 September 2009.
