Cannabis Extracts Efficacious For Patients With Urinary Dysfunction

Thursday, 24 March 2005

Tallahassee, FL: Whole plant medicinal cannabis extracts relieve urinary dysfunction in patients suffering from advanced Multiple Sclerosis, according to clinical trial data published in the April issue of The Journal of Urology.

Fifteen patients participated in the trial. Volunteers were administered extracts containing precise doses of the cannabinoids THC and CBD via and oral spray for eight weeks, followed by the administration of THC only extracts. "Urinary urgency, the number and volume of incontinence episodes, frequency and nocturia (excessive urination at night) all decreased significantly following treatment," authors wrote.

"Cannabis-based medical extracts are a safe and effective treatment for urinary and other problems in patients with advanced MS," the study concluded.

Previous studies in the United Kingdom of patients suffering from advanced stages of MS have noted similar results.

Last December, Health Canada issued a "Qualifying Notice" for the approval of the cannabis extract spray Sativex for the treatment of neuropathic pain associated with Multiple Sclerosis. Regulatory approval for the drug in Britain also remains pending.
