摘要:
A dosage form and method for the delivery of drugs, particularly drugs of abuse, characterized by resistance to solvent extraction, tampering, crushing, or grinding, and providing an initial burst of release of drug followed by a prolonged period of controllable drug release.
摘要:
The present invention provides a pharmaceutical dosage formulation, and more particularly, to a pharmaceutical dosage formulation comprising an HIV protease inhibitor.
摘要:
A solid pharmaceutical dosage form providing improved oral bioavailability is disclosed for inhibitors of HIV protease. In particular, the dosage form comprises a solid dispersion of at least one HIV protease inhibitor and at least one pharmaceutically acceptable water-soluble polymer and at least one pharmaceutically acceptable surfactant, said pharmaceutically acceptable water-soluble polymer having a Tg of at least about 50° C. Preferably, the pharmaceutically acceptable surfactant has an HLB value of from about 4 to about 10.
摘要:
Shaped articles which are suitable as biocidal depth-type filters and consist of fibrous materials and particles, embedded therein, of crosslinked crospovidone-iodine or crospovidone-hydrogen peroxide.
摘要:
A process for the production of divisible tablets by melt calendering in which two molding rolls are combined together, at least one of which has depressions with at least one bar which extends up to the surface line of the molding roll and forms a score.
摘要:
A process for preparing polymers comprising peroxycarboxyl groups, wherein a suspension of a polymer comprising monoolefinically unsaturated dicarboxylic anhydride basic building blocks is mixed with hydrogen peroxide in an inert diluent.
摘要:
A process for producing active substance compositions in the form of a solid solution of the active substance in a polymer matrix, which comprises melt extrusion of the active substance in nonionic form together with a polymer and a salt.
摘要:
A delivery system for sustained release of a calcium-channel blocking agent is adapted for introduction in the cerebrospinal fluid of a subject. The delivery system comprises a solid dispersion product of a calcium-channel blocking agent in a mixture of a (i) first poly(lactide-co-glycolide) having a molecular weight distribution centered around a first number average molecular weight Mn1 and a (ii) second poly(lactide-co-glycolide) having a molecular weight distribution centered around a second number average molecular weight Mn2, wherein Mn1 is in the range of from 2000 to 3000 g/mol and the ratio of Mn1/Mn2 is from 1.8 to 3.5. The delivery system is deposited in the vicinity of or adjacent to a blood vessel showing vasospasm or suspected of developing vasospasm.

摘要:
A solid dosage form having a matrix with at least one active compound dispersed homogeneously in the matrix, which is obtainable by melting a powder mixture, wherein the powder mixture comprises at least one thermoplastic binder and a combination of highly disperse silica and at least one inorganic pigment, is described. The co-use of the highly disperse silica and the inorganic pigments leads to better flow properties of the powder mixture, has the effect of a faster release of the active compound from the dosage forms obtained, and imparts a visually pleasing appearance to the dosage forms. A process for the preparation of the dosage form is also described.
