Drug repurposing shows promise in the treatment of retinal degenerations, according to a new study. A combination treatment incorporating three existing drugs—tamsulosin, metoprolol and bromocriptine—slowed disease progression in pre-clinical retinopathy models. Drug repurposing refers to the use of existing drugs to treat diseases or conditions that they were not originally developed or approved for. The new study focused on drug repurposing in the context of inherited retinal degenerations, IRDs. IRDs are a group of genetic diseases that cause the deterioration of retinal anatomy and function, leading to gradual loss of vision and often blindness. Most IRDs are currently inaccessible therapeutically,...
