  • Publication number: 20050002987
    Abstract: Diazepam is administered intranasally in the form of specific microemulsions having advantageous properties. The microemulsions are comprised of about equal quantities of a fatty acid and water with the remainder being a hydrophilic surfactant, a polar solvent and an alcohol in a weight ratio such that alcohol is present in a greater quantity by weight than either of the other two. Nasal administration of the subject microemulsions produces a high plasma concentration of diazepam nearly as fast as intravenous administration. The present microemulsions are particularly suitable for a prompt and timely treatment of patients in the acute and/or emergency treatment of status epilepticus and other fever-induced seizures.

  • Publication number: 20040028617
    Abstract: A novel method of vehicle modulated administration of an anticonvulsive agent 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 as 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 pharmaceutical preparation produces a high plasma concentration of the anticonvulsant nearly as fast as intravenous administration.
