Trospium is a drug from the group of tropane derivatives and belongs to the synthetic anticholinergics . Chemically, it is a quaternary 3 α - nortropanol , which is esterified with benzilic acid. It is used to treat urge and reflex incontinence .
Clinical information
The pharmacological effect comes about through competitive blocking of the effect of acetylcholine on the muscarinic acetylcholine receptors . This leads to an inhibition of the parasympathetic influence on the smooth muscles , the heart muscle , glands and ganglia of the peripheral nervous system . As a quaternary ammonium ion, trospium is poorly absorbed from the gastrointestinal tract and can hardly penetrate the blood-brain barrier , which is why it has hardly any effects on the central nervous system. In addition, trospium chloride is recognized and discharged by special transporter systems located at the blood-brain barrier.
Pharmacological properties
Contraindications
Contraindications for use are untreated glaucoma , obstructive prostate hyperplasia , intestinal obstruction , pyloric stenosis and other narrowing in the gastrointestinal tract, as well as cardiac arrhythmias with increased heart rate.
Side effects
In principle, the side effects also correspond to those of other anticholinergics; reddening of the skin, bloating , constipation , visual disturbances, reduced perspiration , rapid heartbeat ( tachycardia ), accommodation disorders and a dry mouth may occur.
