摘要:
This invention relates generally to pharmaceutical compositions for treating seizures, and, more particularly, to pharmaceutical compositions that are bioadherent to oral and/or nasal mucosa, comprise one or more anti-acute seizure agents, and can be used to treat one or more conditions selected from the group consisting of acute seizure, repetitive seizures, and status epilepticus. This invention also relates generally to methods for preparing such compositions, methods of treatment using such compositions, uses of such compositions to prepare medicaments, and kits comprising such compositions.
摘要:
A method for treating oral mucositis in a subject comprises topically administering to an oral mucosal surface of the subject phenyloin or a pharmaceutically acceptable salt thereof in an amount effective to inhibit mucosal degeneration or promote mucosal regeneration, and optionally an analgesic agent in an amount effective, in combination with the phenyloin or salt thereof, to reduce pain associated with the oral mucositis. The phenyloin or salt thereof and optionally the analgesic agent can be administered in a pharmaceutical composition comprising an excipient vehicle suitable for intraoral administration, said composition being bioadhesive to an oral mucosal surface, for example having at least one non-lipoidal internal phase and at least one lipoidal external phase that is bioadhesive to said surface.
摘要:
A composition is disclosed for application to a plant that comprises an exogenous chemical (for example, a postemergent herbicide), an aqueous diluent, and a first excipient substance that is amphiphilic. The weight/weight ratio of the first excipient substance to the exogenous chemical is between about 1:3 and about 1:100. The aqueous composition forms anisotropic aggregates on a wax layer, and the presence of the anisotropic aggregates can be detected by a test described herein. Compositions of the present invention, when applied to plants, provide enhanced biological activity per unit amount of exogenous chemical, as compared to otherwise similar compositions containing surfactants that do not form anisotropic aggregates. Without being bound by theory, it is presently believed that this enhanced biological activity results from the formation or enlargement of hydrophilic channels through the epicuticular wax of the plant.

摘要:
Methods and compositions are disclosed wherein exogenous chemicals are applied to plants to generate a desired biological response. One embodiment of the present invention is a plant treatment composition that comprises an exogenous chemical and a first excipient substance. The first excipient substance is an amphiphilic quaternary ammonium compound or mixture of such compounds, having the formulaR.sup.8 --W.sub.a --X--Y.sub.b --(CH.sub.2).sub.n --N.sup.+ (R.sup.9)(R.sup.10)(R.sup.11) T.sup.-wherein R.sup.8 represents the hydrophobic moiety and is a hydrocarbyl or haloalkyl group having from about 6 to about 22 carbon atoms, W and Y are independently O or NH, a and b are independently 0 or 1 but at least one of a and b is 1, X is CO, SO or SO.sub.2, n is 2 to 4, R.sup.9, R.sup.10 and R.sup.11 are independently C.sub.1-4 alkyl, and T is a suitable anion.

A composition is disclosed for application to a plant that comprises glyphosate, an aqueous diluent, and an excipient substance that is amphiphilic. The weight/weight ratio of the excipient substance to the exogenous chemical is between about 1:3 and about 1:100. The aqueous composition forms anisotropic aggregates on a wax layer, and the presence of the anisotropic aggregates can be detected by a test described herein. Compositions of the present invention, when applied to plants, provide enhanced biological activity per unit amount of glyphosate, as compared to otherwise similar compositions containing surfactants that do not form anisotropic aggregates. Without being bound by theory, it is presently believed that this enhanced biological activity results from the formation or enlargement of hydrophilic channels through the epicuticular wax of the plant.
