Shares in Czech drugmaker Zentiva fell more than 7 percent in early Friday trade after the company said first-half results would be lower than expected.

The stock opened 3.5 percent lower and by 0737 GMT was down 7.2 percent at 1,317 crowns.

Zentiva, one of the largest central European generics drug producers, said it expected net income of around 0.8 billion crowns ($39.06 million), operating profit of around 1.1 billion crowns, and net sales of around 6.8 billion crowns.

Zentiva, whose largest shareholder is France's Sanofi-Aventis with a 24.9 percent stake, will release first-half results on Aug. 6, when it also plans to give an update on the outlook for full-year 2007.
