摘要:
The invention comprises a medicinal aerosol composition comprising a propellant, an excipient comprising an acid or amine end-group and at least one and no more than two amide and/or ester functional groups, and a drug. The invention also comprises particulate medicinal compositions comprising particles with a mean mass aerodynamic diameter of less than about 10 microns that incorporate an excipient containing an acid or amine end-group and at least one and no more than two amide and/or ester functional groups.
摘要:
Novel compounds which are 2,6-di-t-butylphenols substituted on the 4 position by an anilino group, which anilino group is substituted by a carboxyl substituent, a tetrazolyl substituent or an N-methyltetrazolyl substituent, are useful antiallergic agents. Pharmaceutical compositions containing and pharmacological methods of using such compounds are also disclosed, as are synthetic intermediates for preparing such compounds. Certain of the synthetic intermediates also exhibit useful antiallergic activity.
摘要:
Chemically-modified collagen is prepared by reacting native collagen with a di or tri-carboxylic acid halide, di or tri-sulfonyl halide, di or tri-anhydride, or di or tri-reative active ester coupling agent. The reaction is done in a controlled manner so that the degree of cross-linking is limited. Any remaining lysine epsilon amino groups present in the coupled collagen product may be converted to carboxyamido or sulfonamido groups by acid halide, anhydride, sulfonyl halide or active ester amine-modifying agents. The resultant product when dissolved in a physiological buffer provides a viscoelastic solution having therapeutic application in a variety of surgical procedures, particularly in ophthalmic surgery. This viscoelastic solution "melts," i.e., exhibits a dramatic loss of viscosity, when subjected to temperatures of between 32.degree. and 48.degree. C.
