NAFDAC Instructs Emergency Manufacturing of Chloroquine

The Director General of the National Agency of Food and Drug Administration and Control, Prof. Mojisola Adeyeye, on Monday, instructed manufacturing of chloroquine for emergency stock for treatment of coronavirus.

The NAFDAC boss in a statement, said the anti-malaria drug was reported to function as anti-viral at both the entry and post-entry stages of 2019-nCoV infection. She added that chloroquine had also been reported as potential broad spectrum anti-viral drug.

She noted that Lagos would begin clinical trial of the drug to evaluate its effectiveness, while calling on the public to desist from its use without the guidance of a medical doctor or clinician for cases of clinical trial treatment of COVID-19.

She said, “Chloroquine, an old anti-malarial, is being re-purposed for the clinical trial treatment of coronavirus 2019-nCoV. The drug was first tested in vitro (in the lab) using standard assays to measure the effects on the cytotoxicity, virus yield and infection rates of 2019-nCoV.

“The drug was reported to function as antiviral at both the entry and post-entry stages of 2019-nCoV infection. Chloroquine has also recently been reported as potential broad spectrum antiviral drug. In a very recent publication, chloroquine was reported in a press briefing by the State Council of China, indicating that chloroquine phosphate had demonstrated marked efficacy and acceptable safety in treating COVID-19 associated pneumonia in a multi-center clinical trial conducted in China.

“The study involved 10 hospitals in Wuhan, Jingzhou, Guangzhou, Beijing, Shanghai, Chongqing and Ningbo, and 100 patients. The investigators reported that chloroquine phosphate is superior to the control in inhibiting the pneumonia associated with COVID-19, and shortening the course of the disease.”

The DG of NAFDAC noted that the drug was discontinued in Nigeria many years ago for use as anti-malarial because of the resistance that the parasite developed against it.

She said, “Therefore, sourcing the raw material – active pharmaceutical ingredient- chloroquine phosphate could be difficult.

“About four weeks ago, I approached a local manufacturing company (May and Baker), a member of Pharmaceutical Manufacturing Group of Manufacturing Association of Nigeria, whose flagship product in the past was chloroquine, to make a batch of the drug for emergency stock.

The company had NAFDAC approval for the production of the drug as anti-malarial many years ago before the discontinuation.”

According to Adeyeye, despite initial difficulty expressed by the managing director of the company, the hurdle was later removed, leading to the production of the drug with more to be manufactured.

She added, “He called shortly after that he was able to get the API and was asked to manufacture a batch for emergency stock just in case more people become exposed and infected with the virus. The batch has been manufactured and the company plans to make more batches if needed.
