    摘要: An ocular drug delivery vehicle of an oil-in-water submicron emulsion comprising about 0.5 to 50% of a first component of an oil, about 0.1 to 10% of a second component of an emulsifier, about 0.05 to 5% of a non-ionic surfactant and an aqueous component, with the mean droplet size being in the submicron range, i.e., below about 0.5 .mu.m and preferably between about 0.1 and 0.3 .mu.m. Also, topical pharmaceutical compositions containing a drug such as an anti-glaucoma drug, beta adrenergic blocker or other autonomic system drug, a local anesthetic, a steroid, a non-steroidal anti-inflammatory drug, an antibiotic drug, an antifungal drug, an antiviral drug or combinations thereof and the vehicle described above. Methods of administering such vehicles or compositions to the eye of a patient while reducing irritation thereof and providing increased bioavailability of the drug.

    摘要: The present invention provides pharmaceutical vaccine compositions that are nanoemulsions of particles having a lipid core which is in a solid or liquid crystalline phase at 25.degree. C., and which is surrounded by at least one phospholipid bilayer for the parenteral, oral, intranasal, rectal, vaginal or topical delivery of both hydrophilic and lipophilic immunogens. The particles have a mean diameter in the range of 10 to 250 nm and the immunogen is incorporated therein, either intrinsically prior to the homogenization process or extrinsically thereafter.

    摘要: The present invention relates to a delivery system which includes a bioactive drug or cosmetic substance presented in the form of submicron oil spheres alone, or drugs or cosmetic substances in a combination with the oil spheres in an aqueous suspension or emulsion. Optionally, a skin penetration enhancer may be included in such formulations. Such preparations achieve improved bioavailability and exert larger pharmacological effects than an equivalent dose of the drug or cosmetic formulated in conventional creams, lotions or oleaginous bases.
