BEIJING - China has banned a domestically produced antibiotic after a child died from being treated with it and other patients suffered effects ranging from diarrhea to anaphylactic shock, the government said Friday.

A 6-year-old girl from Harbin, the capital of northeastern China's Heilongjiang province, died July 24 after being injected with the drug produced by a company in the eastern Anhui province, the official Xinhua News Agency said.

The ban applied to all batches of the drug clindamycin phosphate glucose ¡ª used to treat bacterial infections, produced in the past two months by Huayuan Worldbest Biology Pharmacy Co., a notice posted on the Ministry of Health's Web site said.

The ministry notice did not mention whether the drug had caused any deaths or say how many people were sickened. A press officer with the ministry who would only give his surname, Ma, said no other details could be provided as authorities were still investigating the case.

Xinhua cited the director of Harbin's drug-monitoring center as saying the girl developed a high fever 20 minutes after the injection, and slipped into a coma shortly after.

"Based on all materials we have gathered, a preliminary judgment can be made that the girl was killed due to the injection of the clindamycin phosphate glucose produced by Anhui's Huayuan Worldbest Biology Pharmacy Co.," Sun Pengli, the director, was quoted as saying.

A man working in the production department of Huayuan who refused to give his name said the company notified authorities and recalled the product after discovering the problem a couple of weeks ago. He did not give specific dates.

Production of the drug was immediately stopped, and an internal investigation is ongoing, he said.

The health ministry said that some patients also reported kidney pains, stomach aches, nausea, vomiting and chest pains after using the drug.

China's pharmaceutical industry is highly lucrative but spottily regulated, enticing some to try to cash in by substituting fake or substandard ingredients.

In a separate case earlier this year, 11 people were killed after injecting a drug made by the Qiqihar No. 2 Pharmaceutical Co. Ltd. in the northeastern province of Heilongjiang.

An investigation showed that the drug, called Armillarisni A, contained a chemical, diglycol, that can cause kidney failure, which a vendor had passed off as a normal ingredient.
