Teva Pharmaceutical Industries is always looking for acquisitions and will move on other potential targets when it finds a strategic fit, its top executive said on Monday.

"We are scrutinizing constantly the opportunities and in due time we will move for further acquisitions when we find them a ... strategic fit," Teva CEO Shlomo Yanai said at a briefing in Tokyo.

Teva said on Monday that it would acquire 57% of privately held Taiyo Pharmaceutical Industry for $460 million in cash and would make an offer to buy the remaining shares of Japan's third-largest generic pharmaceutical company.
