Abstract

Potential complications of prescription opioid use include abuse and constipation. 6β-Naltrexol (6βNTX), a neutral opioid antagonist, may alleviate these complications when co-formulated with μ-opioid analgesics. In a double-blind ascending dose study, four subjects on methadone maintenance received 6βNTX (0.05, 0.15, 0.50 and 1.0 mg). 6βNTX was generally well tolerated; three of four subjects reported willingness to take higher doses. Increased gastrointestinal activity was evidenced by decreased oral-cecal transit time and prompt laxation at higher doses.
