GlaxoSmithKline Plc (GSK.L) is facing a criminal investigation in Poland for allegedly bribing doctors to promote its asthma drug Seretide, BBC Panorama reported on Sunday.
The BBC reported that 11 doctors and a GSK regional manager have been charged over alleged corruption between 2010 and 2012.
"The investigation found evidence of inappropriate communication in contravention of GSK policy by a single employee. The employee concerned was reprimanded and disciplined as a result," the drugmaker was quoted as saying.
GSK could not be reached immediately outside regular working hours.
According to the BBC, one doctor has admitted guilt and has been fined and given a suspended sentence.
GSK, Britain's biggest drugmaker, was accused by Chinese authorities in July of funnelling up to 3 billion yuan ($483 million) to doctors and officials to encourage them to use its medicines in a case that rocked the pharmaceuticals industry.
