Scientists are developing a new approach to drug delivery using photopharmacology, where medications can be switched on and off with specific wavelengths of light. The research focuses on creating a switchable beta blocker that could be selectively activated only in targeted areas of the body.
The technology aims to address a major challenge in medicine: reducing side effects from systemic drug distribution. Currently, orally administered medications affect the entire body, including organs where the drug's effects may be unwanted or harmful.
