摘要:
A multiparticulate for controlled release of a drug comprises crystalline drug, a glyceride having at least one alkylate substituent of at least 16 carbon atoms, and a poloxamer, wherein at least 70 wt % of the drug in the multiparticulate is crystalline.
摘要:
A pharmaceutical composition comprises a solid adsorbate comprising a drug adsorbed onto a substrate and a lipophilic microphase-forming material. The solid adsorbate may also be co-administered with a lipophilic microphase-forming material to an in vivo use environment. The compositions of the present invention enhance the concentration of drug in a use environment.
摘要:
A dosage form comprises a low-solubility drug, and a precipitation-inhibiting polymer. The drug is in a solubility-improved form and in the form of particles at least partially coated with the precipitation-inhibiting polymer. Exemplified low-solubility drugs are ziprasidone and sildenafil. Exemplified precipitation-inhibiting polymer is HPMCAS.
摘要:
High loading immediate release dosage forms containing at least 30 wt % of a solid drug dispersion, at least 5 wt % of a disintegrant and a porosigen are disclosed that exhibit excellent strength and aqueous solubility.

摘要:
A controlled release dosage form for sertraline has a core comprising a sertraline-containing composition and a water-swellable composition wherein the water-swellable composition is in a separate region within the core. A coating around the core is water-permeable, water-insoluble, and has at least one delivery port therethrough. In one embodiment, the dosage form releases sertraline to the use environment at an average rate of 6 to 10 wt % per hour from the second to the twenth hour after introduction to a use environment and less than about 25 wt % for the first two hours and at least 70 wt % by the twelfth hour, where the percentages correspond to the mass of drug released from the tablet divided by the total mass of drug originally present in the tablet. In another embodiment, the dosage form releases less than about 25 wt % of sertraline to the use environment by the second hour after introduction of the dosage form to the use environment, and delivers at least 25 wt % from the eighth to the twenty-fourth hour.
摘要:
A controlled release dosage form has a coated core with the core comprising a drug-containing composition and a water-swellable composition, each occupying separate regions within the core. The drug-containing composition comprises a low-solubility drug and a drug-entraining agent. The coating around the core is water-permeable, water-insoluble and has at least one delivery port therethrough. A variety of formulations having specific drug release profiles are disclosed.
