摘要:
A pharmaceutical composition in a form of an anhydrous self-nanoemulsifying oily formulation comprising: one or more therapeutic agent(s) which have low solubility in water or are water-insoluble, vitamin E, one co-solvent selected from propylene glycol and ethanol and mixture thereof one surfactant selected from tyloxapol and from mixture of tyloxapol and TPGS, and optionally, a bioenhancer.
摘要:
Hydrogels having improved elasticity and mechanical strength properties are obtained by subjecting a hydrogel formulation containing a strengthening agent to chemical or physical crosslinking conditions subsequent to initial gel formation. Superporous hydrogels having improved elasticity and mechanical strength properties are similarly obtained whenever the hydrogel formulation is provided with a foaming agent. Interpenetrating networks of polymer chains comprised of primary polymer(s) and strengthening polymer(s) are thereby formed. The primary polymer affords capillary-based water sorption properties while the strengthening polymer imparts significantly enhanced mechanical strength and elasticity to the hydrogel or superporous hydrogel. Suitable strengthening agents can be natural or synthetic polymers, polyelectrolytes, or neutral, hydrophilic polymers.
摘要:
A pharmaceutical composition in a form of a self-microemulsifying drug delivery system comprising: one or more therapeutic agent(s) which have low solubility in water or are water-insoluble, vitamin E, one co-solvent selected from propylene glycol and ethanol, one or more bile salts, TPGS, and one further surfactant selected from Tyloxapol and polyoxyl hydrogenated castor oil.
