Antispasmodics

Papaverine (Latin papaver, "poppy") is an opium alkaloid antispasmodic drug, used primarily in the treatment of visceral spasms and vasospasms (especially those involving the intestines, heart, or brain), occasionally in the treatment of erectile dysfunction and acute mesenteric ischemia. While it is found in the opium poppy, papaverine differs in both structure and pharmacological action from the analgesic morphine and its derivatives (such as codeine).

Hyoscyamine (also known as daturine or duboisine) is a naturally occurring tropane alkaloid and plant toxin. It is a secondary metabolite found in certain plants of the family Solanaceae, including henbane, mandrake, angel's trumpets, jimsonweed, the sorcerers' tree, and Atropa belladonna (deadly nightshade). It is the Levorotatory isomer of atropine.

An antispasmodic (synonym: spasmolytic) is a pharmaceutical drug or other agent that suppresses muscle spasms.

Dicycloverine, also known as dicyclomine, sold under the brand name Bentyl among others, is a medication that is used to treat spasms of the intestines such as those that occur in irritable bowel syndrome (IBS). It is taken by mouth or by injection into a muscle. While it has been used in baby colic and enterocolitis, evidence does not support these uses.

chemical compound

Drotaverine (INN, also known as drotaverin) is an antispasmodic drug, used to enhance cervical dilation during childbirth and to relieve smooth muscle spasms in the gastrointestinal tract, urinary system, and gall bladder.

Moxaverine has been used in therapy based on the direct vasodilatory effect of the drug, a phosphodiesterase inhibitor, and on its influence on the rheological properties of red blood cells.

Ambucetamide is an antispasmodic found to be particularly effective for the relief of menstrual pain. It was discovered in 1953 by Paul Janssen.

Amixetrine (INN; brand name Somagest; developmental code CERM-898) is a drug that was formerly marketed in France but is now no longer sold. According to various sources it has been said to be an anti-inflammatory, antidepressant, antispasmodic, anticholinergic, antihistamine, and antiserotonergic, but its definitive indications and pharmacology are unclear. The drug was first synthesized in 1969 and was introduced in France in 1972.
