Three doctors in Shanghai and one in Hunan Province have been suspended pending investigations over kickbacks they allegedly took from pharmaceutical firms.
In an investigative report aired on Saturday, China Central Television showed pharmaceutical sales representatives paying sweeteners to doctors at six hospitals in Shanghai and central Hunan Province.
The report said the bribes amounted to 30 to 40 percent of the sales price of the drugs.
Anti-graft authorities in Shanghai are investigating the case. Authorities in Hunan promised to improve supervision of pharmaceutical sales in the interests of patients.
The National Health and Family Planning Commission has sent teams to Shanghai and Hunan to investigate.
