A medication used to treat high blood pressure might be useful in addiction treatment, a study of rats suggests. The drug, called isradipine, erased memories that led the rats to associate a certain room with cocaine or alcohol.
The University of Texas researchers trained rats to associate either a white or black room with a dose of cocaine or alcohol, Popular Science reports. Once they were trained, the rats always chose the color room that was associated with their addicted substance.
The researchers then gave the rats isradipine. Right after they took the drug, the rats returned to the same room. But in the following days, they did not show a strong preference for either room.
