Opioid antagonists and butorphanol dependence
Pharmacology Biochemistry and Behavior, 1993Butorphanol has been known to act on mu-, delta-, and kappa-opioid receptors, mu- and possibly delta-receptors are thought to mediate morphine dependence. Relative to morphine, butorphanol has a higher affinity for mu- and delta-receptors. In the present study, beta-funaltrexamine (beta-FNA) and naltrindole (NTI) (nonequilibrium mu- and delta ...

Sustained-Release Butorphanol Microparticles
Drug Development and Industrial Pharmacy, 2000Various butorphanol-loaded microparticles have been prepared with a biodegradable copolymer P(FAD-SA) of erucic acid dimer (FAD) and sebacic acid (SA) and a copolymer P(CPP-SA) of carboxyphenoxypropane (CPP) and SA using a melt compounding and milling method. Drug release was measured in vitro following incubation of drug-loaded microparticles in water

New Zealand Veterinary Journal, 1997
Cardiovascular, pulmonary and anaesthetic-analgesic responses were evaluated in 18 male and female dogs to determine the effect of the injectable anaesthetic propofol used in conjuction with acepromazine and butorphanol. The dogs were randomly divided into three groups.

Acute care, 1988
Butorphanol tartrate is a highly effective opioid agonist-antagonist analgesic with qualitative as well as quantitative differences from the pure agonists. These differences are thought to be due to interaction with a distinct subset of opioid receptors.
