Doctors think they have hit on a way to effectively double supplies of a drug that fights bird flu. Administering Tamiflu alongside a second drug that stops it being excreted in urine means that only half doses of the treatment would be needed. As bird flu threatens to spread, officials are keen to find better treatments…..
The technique was invented during the Second World War to extend precious penicillin supplies. Scientists found that a simple benzoic acid derivative called probenecid stops many drugs, including antibiotics, being removed from the blood by the kidneys. Probenecid is readily available and is still widely used alongside antibiotics to treat gonorrhoea and syphilis, and in emergency rooms, where doctors need their patients to have high, sustained levels of antibiotics in their blood.
Good to know.
