TRANSNASAL ANTICONVULSIVE COMPOSITIONS AND MODULATED PROCESS

摘要

A novel method of vehicle modulated administration of an anticonvulsive agen t to the mucous membranes of humans and animals is disclosed. The vehicle system is an aqueous pharmaceutical carrier comprising an aliphatic alcohol (10-80 %) or a glycol (10-80 %), and their combinations with a biological surfactant such a s a bile salt or a lecithin. The pharmaceutical composition provides a means to control and promote the rate and extent of transmucosal permeation and absorption of the medicaments via a single and multiple administration. Nasal administration of the pharmaceutic al preparation produces a high plasma concentration of the anticonvulsant nearly as fast as intravenous administration. Such compositions are particularly suitable for a prompt and timely medication of patients in the acute and/or emergency treatment of status epilepticus and other fever-induced seizures.
