Abstract: 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.

Abstract: Pharmaceutical compositions are described for preventing neurotoxicity, crising as active ingredient the stereospecific (+) enantiomer, having (3S,4S) configuration of .DELTA..sup.6 tetrahydrocannabinol type compounds. The compositions are particularly effective in alleviating and even preventing neurotoxicity due to acute injuries to the central nervous system, including mechanical trauma, compromised or reduced blood supply as may occur in cardiac arrest or stroke, or poisonings. They are also effective in the treatment of certain chronic degenerative diseases characterized by gradual neuronal loss.

Abstract: 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.

Abstract: The present invention relates to dry, stable compositions which can be reconstituted to form pharmaceutical or cosmetic emulsions, and to methods for making such compositions. An emulsion is formed from about 0.2 to 25 weight percent of a first component of an oil, about 0.1 to 5 weight percent of a second component of an emulsifier, about 0.25 to 25 weight percent of a cryoprotectant of an amino compound, such as one or more amino acids, peptides or protein hydrolysates, and an aqueous component, wherein the amino compound is present in an amount that is equal to or greater than that of the first component. Optionally, a co-emulsifier, a suspension agent, a preservative, an antioxidant and a drug can be added to these emulsions. Thereafter, the emulsion is lyophilized to form dry compositions that have from about 40 to about 90 weight percent of the amino compound; from about 0.1 to about 20 weight percent of the emulsifier; and from about 0.2 to about 40 weight percent of the oily component.

Abstract: The present invention provides certain novel 4-phenylpinene derivatives, and teaches how to use said novel derivatives and related compounds in pharmaceutical compositions that have utility in treating various pathological conditions associated with damage to the central nervous system. The active ingredient of the pharmaceutical compositions according to the present invention is a compound of the formula: ##STR1## wherein A - - - B designates an optional double bond, R.sub.1 designates a variety of organic moieties, G designates alkyl, halogen, or various oxy groups, and R.sub.3 designates various alkyl groups, ether groups, or combinations thereof.
