摘要:
Provided herein are methods for treating pain such as acute or chronic pain or fever in subject without risking hepatotoxicity. The subject may be at risk of hepatotoxicity if administrated an acetaminophen monomer. The method includes administering a pharmaceutical composition containing an acetaminophen dimer compound, wherein the phenolic hydroxyl groups of two acetaminophen compounds are linked via an ethylene spacer.
摘要:
The present invention provides a buprenorphine dimer compound, wherein the two buprenorphine portions are linked via an ethylene spacer, wherein the spacer is bonded to the two opioid molecules via an ether bond. Pharmaceutical compositions comprising such a buprenorphine dimer drug are also disclosed, and the use of such compounds in the treatment of gastrointestinal hyperalgesia generally and in particular diarrhea-predominant irritable bowel syndrome.
摘要:
The present invention provides a method of providing pain relief in a human subject in need thereof comprising administering (R)-dihydroetorphine to said subject, wherein said (R)-dihydroetorphine is administered in a dose of at least 0.01 μg/kg, preferably at least 0.05 μg/kg, and the level of respiratory depression in said subject is 65 or less % relative to the baseline level pre-administration of (R)-dihydroetorphine.
摘要:
The present invention is directed to Buprenorphine Analog compounds of the Formula (I), Formula (IA) or Formula (IB) shown below, wherein R1, R2, R8, R3a, R 3b, G, X, Z and Y are as defined herein. Compounds of the Invention are useful for treating pain, constipation, and other conditions modulated by activity of opioid and ORL-1 receptors.
摘要:
The present disclosure provides improved methods for N-dealkylation of tertiary amines, including methods for N-demethylation of alkaloids and opioids, in which the dealkylation reaction is carried out in a solvent comprising a tertiary alcohol. The present disclosure also provides improved processes for preparing semi-synthetic opioids that incorporate the disclosed methods for N-dealkylation of tertiary amines.
摘要:
