Title:
ジアゼパムを含有する経鼻マイクロエマルジョン
Document Type and Number:
Japanese Patent JP2006527764
Kind Code:
A
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.
