The purpose of this work was the formulation of liposomes for nasal administration of tacrine-HCl. This route has many advantages; in particular is possible to convey the drug directly to the Central Nervous System, through the olfactory bulb. Part of Tacrine administered can also be absorbed into the systemic circulation avoiding hepatic first pass effect. Liposomes were formulated with ingredients that have a beneficial effect against the disease.

Abstract

The purpose of this work was the formulation of liposomes for nasal administration of tacrine-HCl. This route has many advantages; in particular is possible to convey the drug directly to the Central Nervous System, through the olfactory bulb. Part of Tacrine administered can also be absorbed into the systemic circulation avoiding hepatic first pass effect. Liposomes were formulated with ingredients that have a beneficial effect against the disease. In particular, the classical excipients cholesterol and phosphatidylcholine were enriched with α-tocopherol and polyunsaturated fatty acid EPA and DHA. This formulative approach allowed us to obtain 100% active liposomes against symptoms of Alzheimer's disease.
