Long-acting malaria pill a step closer

FOLLOW US:

Washington: Scientists have developed a new drug capsule that remains in the stomach for up to two weeks after being swallowed, gradually releasing its payload, paving the way for a long acting pill that may effectively treat malaria and many other diseases, says PTI.

This type of drug delivery could replace inconvenient regimens that require repeated doses, which would help to overcome one of the major obstacles to treating and potentially eliminating diseases such as malaria. Researchers at Massachusetts Institute of Technology (MIT) and Brigham and Women’s Hospital in the US used this approach to deliver a drug called ivermectin, which they believe could aid in malaria elimination efforts.


However, this approach could be applicable to many other diseases, said Robert Langer, Professor at MIT. “This really opens the door to ultra-long-lasting oral systems, which could have an effect on all kinds of diseases, such as Alzheimer’s or mental health disorders,” he said.

Drugs taken orally tend to work for a limited time because they pass rapidly through the body and are exposed to harsh environments in the stomach and intestines. Langer’s lab has been working for several years to overcome this challenge, with an initial focus on malaria and ivermectin, which kills any mosquito that bites a person who is taking the drug.

This can greatly reduce the transmission of malaria and other mosquito-borne illnesses. The team envisions that long-term delivery of ivermectin could help with malaria elimination campaigns based on mass drug administration – the treatment of an entire population, whether infected or not, in an area where a disease is common. The research was published in the journal Science Translational Medicine.
