Korea's major pharmaceutical companies spent around 100 billion won ($72.13 million) each in the first half for the research and development (R&D) of new drugs, data showed Sunday, in an apparent bid to secure future growth engines.

Yuhan Corp., famous for its anti-inflammatory ointment Antiphlamine, said in a regulatory filing that it invested a total of 122.2 billion won in R&D during the January-June period, up 13.8 percent from the same period last year.

The amount accounts for 10.5 percent of sales generated during the first half of this year, according to its regulatory filing.

Chong Kun Dang Pharmaceutical Corp., known for its household pain reliever Penzal, injected 113.5 billion won, or 12.3 percent of its first half sales, into new drug development.
