| Treatment | Overdosage should be treated with atropine titration (0. 5 mg to 1. 0 mg given subcutaneously or intravenously) and supportive measures to maintain respiration and circulation. Epinephrine (0. 3 mg to 1. 0 mg, subcutaneously or intramuscularly) may also be of value in the presence of severe cardiovascular depression or bronchoconstriction. (L1712) |
| Hepatotoxicity | In clinical trials of pilocarpine, serum enzyme elevations were uncommon and no more frequent than with placebo. Despite, wide scale use, there have been no published reports of acute liver injury attributable to pilocarpine. |
| 유해 작용 | As the drug acts as a cholinergic agonist, pilocarpine may propagate muscarinic side effects, particularly when used in the oral form. The muscarinic receptors are present in nearly all major organ systems, and muscarinic medications can mediate autonomic function wherever the receptors are present. Due to the receptor's role in mediating the response of the parasympathetic nervous system, stimulation of the receptors will cause "rest and digest" functions throughout the distribution of M1-M5 receptor locations: the neuronal, cardiac, musculoskeletal, pulmonary, digestive, and urinary systems. |
용도
개요
Pilocarpine acts by stimulating muscarinic receptors, therefore making it similar in action to acetylcholine when systematically introduced. This compound differs from acetylcholine in that it does not react with any nicotinic receptors, but by stimulating the CNS. Its effects are blocked by atropine. It has found therapeutic use in ophthalmology as a myotic agent.
역사
It has a history of hundreds of years since pilocarpine was used to treat glaucoma .In 1933, the chemical synthesis of pilocarpine was firstly reported. However, pilocarpine couldn’t be used for treatments, because its synthetic route is so long and focuses on isopilocarpine, of which the pharmacological activities are 1/20– 1/50 of pilocarpine. In 1972, DeGraw successfully synthesized the cis-homopilopic acid employing catalytic hydrogenation of precious metals and obtained pilocarpine as the main part product. Therefore, the study on the production of pilocarpine by chemical synthesis has made new progress and has been artificially synthesized .
용도
Pilocarpine occurs in the leaves of variousspecies of pilocarpus. It is used as an antidotefor atropine poisoning and in ophthalmologyto produce contraction of the pupil.
