Characterization of a cyclosporine solid dispersion for inhalation

Microspherical Particles of Solid Dispersion of Polyvinylpyrrolidone K29-32 for Inhalation Administration

Inhalation administration is a promising alternative to the invasive drug delivery methods. The particle size required for ideal drug aerosol preparation is between 1 and 3 μm. The application of microspherical particles of solid dispersions enhances bioavailability of poorly soluble drugs due to the solubilization. In the present work, the spray drying process of the production of microspheric...

Physicochemical characterization and aerosol dispersion performance of organic solution advanced spray-dried cyclosporine A multifunctional particles for dry powder inhalation aerosol delivery

In this systematic and comprehensive study, inhalation powders of the polypeptide immunosuppressant drug - cyclosporine A - for lung delivery as dry powder inhalers (DPIs) were successfully designed, developed, and optimized. Several spray drying pump rates were rationally chosen. Comprehensive physicochemical characterization and imaging was carried out using scanning electron microscopy, hot-...

Formulation And Characterization Of Telmisartan Using Solid Dispersion Techniques

Telmisartan (TLM) is an angiotensin II receptor antagonist used in the treatment of hypertension. According to BCS (biopharmaceutical classification system) Telmisartan belongs to class II drug, and it is practically insoluble in water and it shows low dissolution profile and poor absorption. The present study is to improve the solubility of Telmisartan by solid dispersion techniques using vari...

Solubility enhancement of glimperide: Development of solid dispersion by solvent melt method, characterization and dosage form development

The aim of the present work was to develop immediate release dosage form of the solid dispersion of glimperide (GLIM) for potential enhancement in the bioavailability. The solid dispersions of GLIM were prepared with PEG6000, PVP K30 and Poloxamer 188, in 1:1, 1:3 and 1:5 %w/w ratio by using solvent wetting and solvent melt method. The in vitro dissolution parameters (%DE10min, %DE30min, %DE60m...
