FIELD: pharmaceutics.

SUBSTANCE: the suggested pharmaceutical composition at delayed release contains fluvastatin or its pharmaceutically acceptable salt hydroxypropylmethylcellulose and nonionic hydrophilic polymer. The latter is being hydroxyethylcellulose at average molecular weight ranged 90000-1300000 or hydroxypropylcellulose at average molecular weight ranged 370000-1500000 or polyethylenoxide at average molecular weight ranged 100000-500000. The suggested pharmaceutical composition is necessary to obtain peroral medicinal remedy for decreasing cholesterol level in plasma, it, also, provides the supply of fluvastatin into the body during prolonged period of time, for example, for more than 6 h and enables to minimize the possibility for premature release or "discharge" of considerable fluvastatin quantities.
