摘要:
This patent relates a method for increasing the storage stability of physostigmine free base and physostigmine analogs by incorporating the free base into a polymer matrix. Chemically compatible enhancers and adjuvants do not interfere with the stabilization of the free bases.
摘要:
A transdermal patch for delivering nicotine for prolonged periods of 12-24 hours. The patch includes a rate-controlling membrane or monolith to keep the nicotine flux within useful and safe limits. The patch is typically replaced once a day, and can be used for smoking cessation therapy or in other situations where systemic nicotine delivery is indicated.
摘要:
A controlled release transdermal delivery system for nicotine administration. The system comprises an impermeable backing layer, a polyurethane matrix layer containing between about 5 wt % and 50 wt % nicotine, and an adhesive skin-contacting layer. The system is designed to administer nicotine for smoking cessation therapy or other uses over a period of 24 hours or more.
摘要:
This invention relates to methods of treating various orofacial diseases involving inflammation, infection and/or pain, using intratissue controlled release drug delivery systems. More particularly, the invention relates to methods for localized or targeted administration of a sustained release formulation of an agent such as an anti-inflammatory agent to a specified tissue location within the orofacial environment.
摘要:
A method for fabrication of multilayer transdermal drug release devices that divides the assembly of the various drug delivery components of the device into their unit operations; treats the prefabricated units as modules that are later combined to obtain the finished transdermal drug delivery device. A variety of different configurations are available depending upon the drug or drugs to be administered.
摘要:
Combinations of hydrophilic and hydrophobic entities in a biodegradable sustained release implant are shown to modulate each other's rate of release. Formulations of a therapeutically active agent and modulator provide substantially constant rate of release for an extended period of time.
