You Could Soon Be Manufacturing Your Own Drugs -- Thanks To 3D Printing

sciencehabit shares a report from Science Magazine: Forget those long lines at the pharmacy: Someday soon, you might be making your own medicines at home. That's because researchers have tailored a 3D printer to synthesize pharmaceuticals and other chemicals from simple, widely available starting compounds fed into a series of water bottle -- size reactors. The work, they say, could digitize chemistry, allowing users to synthesize almost any compound anywhere in the world. In today's issue of Science, Leroy Cronin, a chemist at the University of Glasgow in the United Kingdom, and his colleagues report printing a series of interconnected reaction vessels that carry out four different chemical reactions involving 12 separate steps, from filtering to evaporating different solutions. By adding different reagents and solvents at the right times and in a precise order, they were able to convert simple, widely available starting compounds into a muscle relaxant called baclofen. And by designing reactionware to carry out different chemical reactions with different reagents, they produced other medicines, including an anticonvulsant and a drug to fight ulcers and acid reflux. So why not just buy a reactionware kit and scrap the printing? "This approach will allow the on-demand production of chemicals and drugs that are in short supply, hard to make at big facilities, and allow customization to tailor them to the application," Cronin says.
