Ursokem-300 general information
What is Ursokem-300 used for?
Ursokem tablets 300mg are used to treat cholestatic disease of liver, which is the build-up of bile in the liver due to impaired formation of bile by the liver and reduced flow of bile out of the liver. This is caused by primary biliary cirrhosis (destruction of the bile ducts, thought to be an autoimmune disease) and primary sclerosing cholangitis (inflammation of the bile ducts) and can result in the formation of gallstones in the liver itself before the bile is released. Bile is produced by the liver and comprises cholesterol, fatty acids, bile salts (formed from bile acids and glycine or taurine amino acids) and the pigment bilirubin, which is a breakdown product of red blood cells. Bile passes through the bile duct into the gall bladder where it is stored, until it is released into the small intestine when food is ingested, to aid the digestion of fat in the diet. The release of cholesterol into bile is also a means of eliminating excess cholesterol. Normally bile contains sufficient bile acids to dissolve the cholesterol, however, if the bile has high cholesterol content, too much bilirubin or too little bile salt content, the cholesterol may form crystals in the gall bladder and eventually turn into gall stones. Impaired or delayed emptying of the gall bladder causes bile to become concentrated and this also contributes to the formation of gall stones. Ursokem-300 dissolves cholesterol gallstones and is effective for small gallstones that do not require surgery or when surgery is not an option. Ursokem-300 is not suitable for other types of gallstones such as pigment gallstones.
How does Ursokem-300 work?
Ursokem tablets 300mg contain ursodeoxycholic acid (also known as ursodiol), which is a secondary bile acid that is produced by metabolism by intestinal bacteria from primary bile acids added to bile in the liver. Ursodeoxycholic acid in Ursokem-300 suppresses the formation of cholesterol by the liver and also reduces the amount of cholesterol absorbed by the intestine, which regulates the body’s cholesterol levels. Ursodeoxycholic acid also acts as a surfactant (detergent) and works by dispersing cholesterol into small droplets or micelles, so that the cholesterol becomes solubilised and can be metabolised more easily. This property of Ursodeoxycholic acid in Ursokem-300 helps break down small gallstones that have a high cholesterol content and do not need surgery to remove them. Dissolution of gallstones is slow and can take months or years of treatment.
What does Ursokem-300 contain?
Ursokem-300 contains the active ingredient ursodeoxycholic acid, a secondary bile acid used to dissolve gallstones.
Treating gallstones with Ursokem-300
Ursokem tablets 300mg contain ursodeoxycholic acid that is used to break up small cholesterol-based gallstones that can form in the liver and in the gall bladder. Gallstones in the liver are the result of build-up of bile in the liver due to impaired formation of bile by the liver and reduced flow of bile out of the liver. Gallstones in the gall bladder is caused by bile that has high cholesterol content, too much bilirubin or too little bile salt content, and as a result the cholesterol forms crystals in the gall bladder and eventually turn into gallstones. Gallstones can also be due to impaired or delayed emptying of the gall bladder. which causes bile to become concentrated. Bile is produced by the liver and comprises cholesterol, fatty acids, bile salts (formed from bile acids and glycine or taurine amino acids) and the pigment bilirubin, which is a breakdown product of red blood cells. Bile passes through the bile duct into the gall bladder where it is stored, until it is released into the small intestine when food is ingested, to aid the digestion of fat in the diet by dispersing cholesterol into small droplets or micelles so that it can be metabolised more easily. Ursodeoxycholic acid in Ursokem-300 works in the same way so that the cholesterol in gallstones becomes solubilised and this helps break up the gallstone. Ursokem 300 helps relieve symptoms of gallstones which vary depending on the size and location of the gallstones. There may be no symptoms at all or severe symptoms including acute abdominal pain, jaundice (yellowing of the skin and whites of the eyes) and fever. Ursokem-300 is only suitable for treatment of small cholesterol-based gallstones and not for other types of gallstones such as pigment gallstones.
