What is PROPARACAINE?

The Uses of PROPARACAINE

Anticholinergic.

The Uses of PROPARACAINE

Propantheline is used for treating stomach ulcers.

Background

A muscarinic antagonist used as an antispasmodic, in rhinitis, in urinary incontinence, and in the treatment of ulcers. At high doses it has nicotinic effects resulting in neuromuscular blocking.

Indications

For the treatment of enuresis. It has also been used for hyperhidrosis, and cramps or spasms of the stomach, intestines or bladder.

Definition

ChEBI: Propantheline is a member of xanthenes.

brand name

Pro-Banthine (Searle).

Pharmacokinetics

Propantheline is an anticholinergic drug, a medication that reduces the effect of acetylcholine, a chemical released from nerves that stimulates muscles, by blocking the receptors for acetylcholine on smooth muscle (a type of muscle). It also has a direct relaxing effect on smooth muscle. Propantheline is used to treat or prevent spasm in the muscles of the gastrointestinal tract in the irritable bowel syndrome. In addition, Propantheline inhibits gastrointestinal propulsive motility and decreases gastric acid secretion and controls excessive pharyngeal, tracheal and bronchial secretions.

Pharmacology

The pharmacological action of propantheline is qualitatively similar to atropine. It has a weaker effect on the CNS than atropine. Unlike atropine, it exhibits greater ganglioblocking action than antimuscarinic action. Moreover, upon overdose it causes neuromuscular curare-like blockage.

Synthesis

Propanetheline, N-methyl-N-(1-methylethyl)-N-[2-[(9H-xanthen-9- ylcarbonyl) oxy]ethyl]-2-propanaminium bromide (14.1.11), is synthesized by reacting xanthen-9-carboxylic acid chloride with 2-di-iso-propylaminoethanol, giving the ester (14.1.10), which upon reaction with methylbromide turns into the quaternary salt, propantheline (14.1.11) [12,13].

Veterinary Drugs and Treatments

Proparacaine is a rapid acting topical anesthetic useful for a variety of ophthalmic procedures including tonometry (intraocular pressure measurement), relief of corneal pain to facilitate examination, biopsy/sample collection, and to distinguish between corneal and uveal pain. Proparacaine primarily anesthetizes the cornea; with limited penetration into conjunctiva. Anesthesia is of short duration (5 – 10 minutes).
