  • Parenteral dosage form
    Patent number: 5643604
    Abstract: Delayed-release formulation intended for administration by parenteral injection, consisting of solid calibrated microspheres (5-300 .mu.m) comprising a pharmaceutically active substance (for example: morphine) contained in spherical structures determined by one or more which are pharmacologically inactive carrier substances (for example: cholesterol), naturally present in the receiving organism, which are pharmacodynamically inactive at the administered doses of said dosage form, having a melting point greater than 60.degree. C. and stable in the solid state in the receiving physiological medium. The dosage form makes it possible to slow and prolong the effect of active substances which are too rapidly soluble in physiological medium (which act on the central nervous or neurovegetative system, such as vasedilators, anti-histaminics, hormones, contraceptives and the like).
