摘要:
A linear block copolymer comprising units of an alkylene oxide, linked to units of peptide via a linking group comprising a --CH.sub.2 CHOHCH.sub.2 N(R)-- moiety, is useful as an imaging agent, drug, prodrug or as a delivery system for imaging agents, drugs or prodrugs.
摘要:
Topical pharmaceutical compositions containing a corticosteroid component and a penetration-enhancing vehicle are disclosed. The vehicle comprises a binary combination of a C.sub.3 -C.sub.4 diol and a "cell-envelope disordering compound". The vehicle provides marked transepidermal and percutaneous delivery of corticosteroids. A method of treating certain rheumatic and inflammatory conditions, systemically or locally, is also disclosed.

There invention discloses aqueous dispersions of nanoparticulate aerosol formulations, dry powder nanoparticulate aerosol formulation, propellant-based aerosol formulations, methods of using the formulations in aerosol delivery devices, and methods of making such formulations. The nanoparticles of the aqueous dispersions or dry powder formulations comprise insoluble drug particles having a surface modifier on the surface thereof.
摘要:
The present invention is directed to nanoparticulate compositions comprising topiramate. The topiramate particles of the composition have an effective average particle size of less than about 2 microns.

摘要:
A large group of lipophilic, pharmacologically active compounds can be effectively delivered across intact skin by applying them topically in a binary, penetration-enhancing vehicle containing (1) a C.sub.3 -C.sub.4 diol, diol ester, or diol ether and (2) a cell envelope-disordering compound. This vehicle provides surprising enhancement of skin penetration for the pharmacological active, compared to either component alone.
摘要:
The invention provides a drug delivery system for the topical administration of therapeutic agents, including therapeutic agent in an amount between 0.001 and 20% by weight, propylene glycol in an amount between 2 and 6% by weight, oleyl alcohol in an amount between 2 and 6% by weight, and a volatile component in an amount between 60 and 95% by weight.
