By Ben Hirschler LONDON (Reuters) - Wholesalers trading medicines across European borders have criticised a suggestion by manufacturers that Greek exports should be restricted to prevent shortages of life-saving drugs in the country. The European Association of Euro Pharmaceutical Companies (EAEPC), representing firms involved in this so-called parallel trade, said drugmakers were wrong to say supplies could be in jeopardy if Europe did not take such emergency action. "The wealthy pharmaceutical industry is exploiting the potential advent of another crisis in Greece for their own commercial purposes in portraying a medicines shortage," EAEPC wrote in a letter to EU Health Commissioner Vytenis Andriukaitis.
