India's pharmaceutical market may grow 12-13 percent in 2009; according to provisional estimates by pharmaceutical research firm ORG IMS Research, its managing director said on Wednesday.

ORG IMS had earlier forecast a 14-15 percent growth but has revised it down, given the current environment, managing director Sameer Savkur said at an industry meet.

"Chronic therapy area will continue to drive growth as we saw in 2008," he said.

He estimates that the Indian pharmaceutical industry will touch $30 billion by 2020. In 2008, the industry grew by about 10 percent, he added.
