Pramocaine

Pramocaine (also known as proparacaine) is a local anesthetic of the amino ester group that is primarily used in topical ointic and ophthalmic preparations. It is also used in some surgical procedures.

History

Pramocaine was first synthesized in the mid-20th century and has been in use as a local anesthetic since then. It is a derivative of para-aminobenzoic acid (PABA).

Pharmacology

Pramocaine works by inhibiting sodium ion channels on the nerve cell membrane, preventing the propagation of action potentials and thus blocking the transmission of pain signals. It is a relatively weak anesthetic and has a short duration of action.

Uses

Pramocaine is primarily used in topical ointic and ophthalmic preparations. It is also used in some surgical procedures, particularly in ophthalmology, for local anesthesia.

Side Effects

Possible side effects of pramocaine include allergic reactions, skin irritation, and systemic toxicity if absorbed in large amounts.

Contraindications

Pramocaine is contraindicated in patients with a known hypersensitivity to it or to any other ester-type local anesthetic. It should also be used with caution in patients with impaired cardiovascular function.
