    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.
