A fine-tuned combination of two existing pharmaceutical drugs has shown promise as a potential new therapy for people addicted to cocaine—a therapy that would reduce their craving for the drug and blunt their symptoms of withdrawal.
In laboratory experiments at The Scripps Research Institute, the potential therapy, which combines low doses of the drug naltrexone with the drug buprenorphine, made laboratory rats less likely to take cocaine compulsively—a standard preclinical test that generally comes before human trials.
While the two-drug combination would have to prove safe and effective for people in clinical trials before approval by the U.S. Food and Drug Administration (FDA), the work represents a significant advance in the field because there are currently no FDA-approved medications for treating cocaine addiction.
