[Uses]

Anticholinergic.
[Uses]

Propantheline is used for treating stomach ulcers.
[Definition]

ChEBI: Propantheline is a member of xanthenes.
[Brand name]

Pro-Banthine (Searle).
[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).
