It is also documented that although Eptazocine, which does not have a morphinane skeleton, but is known to exert a κ agonist action on opioid receptors, contraction of the sphincter of Oddi was confirmed when administered in large quantities in animal experiments, so For patients with biliary tract disease must be carefully administered (non-patent document 9)

Embodiment 1

[0108] Example 1 (-)-17-(cyclopropylmethyl)-3,14β-dihydroxy-4,5α-epoxy-6β-[N-methyl-trans-3-(3-furyl)acrylamide ]Effect of morphinane hydrochloride (compound 1) on contraction of rabbit sphincter of Oddi

[0109] The method described in Wei JG et al., World J. Gastroenterol., 6, 102 (2000) was partially modified to measure changes in the perfusion resistance pressure of the sphincter of Oddi. It should be noted that the changes in the perfusion resistance pressure of the sphincter of Oddi reflect the contraction of the sphincter of Oddi.

[0110] NZW male rabbits (Japan SLC) with a body weight of 2.0 to 2.5 kg upon arrival were used, and fasting was started from the evening of the day before the experiment. The experiment was carried out under pentobarbital anesthesia and artificial ventilation. The rabbit was fixed in the dorsal position, after which the abdomen was incised to expose the periduodenum and common bile duct. The common bile duct was cut slightly, and the ca...

Abstract

Disclosed is a novel medicinal agent which has an excellent therapeutic effect on biliary diseases and is therefore is useful for the treatment or prevention of biliary diseases. Specifically disclosed is a therapeutic or prophylactic agent for biliary diseases, which comprises a compound having a specific morphinan backbone typified by compound 1 or a pharmacologically acceptable acid addition salt thereof as an active ingredient.

Description

technical field [0001] The present invention relates to a medicine for treating or preventing biliary tract disease which contains Morphinan derivative or its pharmacologically acceptable acid addition salt as an active ingredient. Background technique [0002] Biliary tract disease refers to the general term for digestive system diseases that occur in the gallbladder or bile duct or pancreas or pancreatic duct. As one of the causes of biliary tract diseases, it is known that the biliary resistive pressure increases due to the contraction of Oddi's sphincter muscle at the duodenal papilla, which is the terminal part of the bile duct after the common bile duct, which is the most downstream of the biliary duct, joins the pancreatic duct. Examples of biliary diseases caused by contraction of the sphincter of Oddi include biliary occlusion, gallbladder disorder, gallstone, pancreatitis, biliary dyskinesia, cholangitis, and cholecystitis. Therefore, it is known that a drug that ...
