Alverine citrate is a smooth muscle relaxant, that acts directly on intestinal and uterine smooth muscle. Smooth muscle is a type of muscle that is not under voluntary control. It is the type of muscle that is found in places such as the walls of the gut and the walls of the womb (uterus). Alverine citrate acts directly on this muscle, causing it to relax. Alverine citrate relaxes the muscle spasms that occur in the gut in conditions such as irritable bowel syndrome and diverticular disease. This relieves the pain sometimes associated with these conditions. Alverine citrate also relieves the muscle spasms in the womb that cause painful periods.
Buscon (Hyoscine butylbromide) is a quaternary ammonium antimuscarinic agent. Hyoscine butylbromide does not readily pass the blood-brain barrier. It is a competitive antagonist of the actions of acetylcholine and other muscarinic agonists. It is used in the treatment of conditions associated with gastrointestinal spasm. It is available as 5's x 2 blistered 1 ml ampoule in each box.
Irisyn is a musculotropic antispasmodic agent used to relieve cramps or spasms of the stomach and intestine. It is particularly useful in treating irritable bowel syndrome (IBS) and similar conditions. It works by relaxing the muscles and helping to restore the normal movement of the gut.
Visceral (Tiemonium methylsulphate) is a synthetic anticholinergic-antispasmodic drug. Tiemonium methylsulphate is a quaternary ammonium antimuscarinic agent with peripheral effect similar to those of atropine. Tiemonium methylsulphate strengthens calcium bonding with phospholipids and proteins thus stabilizing the cell membrane of the GI tract.
