摘要:
Stabilized pharmaceutical compositions comprising polymorphs of active pharmaceutical ingredients susceptible to conversion to alternate polymorph forms are prepared by a process of wet granulation in which the ratios of active, fillers, and granulating liquid are controlled in order to avoid polymorphic interconversions.
摘要:
The invention relates to the pharmaceutical composition comprising the amorphous active substance which is atorvastatin calcium. The process of stabilization of the pharmaceutical composition comprising the pharmaceutical formulation with amorphous atorvastatin calcium, the process of stabilization of the pharmaceutical formulation comprising amorphous atorvastatin calcium and the process of stabilization of atorvastatin calcium in an amorphous form is described.
摘要:
Composition were developed which stabilize an active pharmaceutical ingredient in polymorph form susceptible to degradation or interconversion into other polymorph forms, where stabilizing substance is conveniently among silicon dioxide, silicified microcrystalline cellulose, magnesium oxide and polyethylene glycol.
摘要:
The present invention belongs to the field of pharmaceutical industry and relates to dosage forms comprising active pharmaceutical ingredients (API) such as tadalafil, simvastatin, fenofibrate and lovastatin that are practically insoluble in water, adsorbed on a carrier. Furthermore it relates to an adsorbate comprising API being practically insoluble in water and to a process for the preparation of said adsorbate with non-polar solvent (s) such as chlorinated hydrocarbon, diisopropylethes and hexane. Furthermore the invention relates to a process for the preparation of the dosage form, as well as to the use of the adsorbate for the preparation of the dosage form. Moreover it relates to the dosage form for use in the treatment of erectile dysfunction, human immunodeficiency virus (HIV) infections and/or Acquired Immune Deficiency Syndrome (AIDS).
摘要:
Process for the preparation of enantiomerically pure methyl ester of rosuvastatin has been developed, wherein the crude methyl ester ester is first purified by preparative chromatography, followed by crystallization.
