Abstract:
The present invention relates to a process for the preparation of unilamellar liposomal composition of a polyene antibiotic drug, preferably amphotericin B. The process encompasses the steps of (a) mixing the polyene antibiotic and the phospholipid in an acidified organic solvent, (b) removing the organic solvent and (c) hydrating the dried complex with an aqueous buffer having a pH of 3 to 6.
Abstract:
The present invention relates to a nanoparticulate topical composition comprising (i) nanoparticles of a water soluble and water susceptible active ingredient or its pharmaceutically acceptable salt, having a particle size distribution such that 90% of the particles are less than 1000 nm, (ii) one or more wetting agent and (iii) a non-aqueous liquid vehicle, wherein the composition is free of water. The present invention also relates to a method of treating acne, rosacea, impetigo or a skin disease caused by a bacteria, by topical application of a nanoparticulate topical composition comprising nanoparticles of a water soluble and water susceptible active ingredient or its pharmaceutically acceptable salt, having a particle size distribution such that 90% of the particles are less than 1000 nm.
Abstract:
An ophthalmic solution comprising therapeutically effective amount of a prostaglandin or its analog and water soluble excipient(s) dissolved in a pharmaceutically acceptable vehicle, wherein the solution is free of a surfactant.
Abstract:
The present invention relates to a method of preparing a nanoparticulate topical composition of a water soluble, water-susceptible active ingredient or its pharmaceutically acceptable salt, the method comprising steps of milling the water soluble, water-susceptible active ingredient or its salt, a wetting agent and a non-aqueous liquid vehicle to obtain a non-aqueous nanosuspension and converting the non-aqueous nanosuspension into a topical composition.
Abstract:
A pharmaceutical composition in the form of a solution comprising water insoluble therapeutically active ingredient and a close structural analog of the water insoluble active ingredient, one or more pharmaceutically acceptable excipients and one or more water miscible solvents wherein the water insoluble active ingredient is present in therapeutically effective amounts and the close structural analog is present in sufficient amounts such that when the composition is added to an aqueous vehicle it forms a nanodispersion suitable for intravenous infusion wherein said nanodispersion is stable for longer periods as compared to a dispersion formed from an identical composition but devoid of the close structural analog of the water insoluble active ingredient.
