Method and dosage form for treatment of premenstrual syndrome
First Claim
1. A method of treating premenstrual syndrome, comprising orally administering to a woman suffering from premenstrual syndrome a therapeutically effective amount of an oral dosage form of progesterone comprising a suspension of micronized progesterone in an edible oil consisting essentially of not more than about 16 wt. % of saturated fatty acid glycerides, and the balance is essentially at least two glycerides of oleic, linoleic, and linolenic acids, said suspension being contained in a pharmacologically acceptable capsule, wherein said dosage form is administered over a period of consecutive days during the second half of the menstrual cycle between ovulation and menstruation in a dosage sufficient to increase blood serum levels of progesterone to at least 10 ng/ml.

Abstract
A pharmaceutical composition suitable for oral administration comprises micronized progesterone in an oil vehicle which is high in glycerides of polyunsaturated fatty acids. Micronized progesterone particles suspended in such an oil vehicle are absorbed more readily into the bloodstream and achieve high progesterone blood serum levels. The pharmaceutical composition according to the invention can be readily formulated into capsules and administered for the treatment of premenstrual syndrome.

12. A method for preparing a pharmaceutical composition comprising micronized progesterone suspended in an edible oil, said oil comprising glycerides of one or more polyunsaturated fatty acids and dissolved progesterone, which method comprises the steps of:
-
mixing a first quantity of progesterone with said oil; heating the resulting mixture to dissolve said first quantity of progesterone in said oil; cooling said mixture to a temperature sufficiently low that micronized progesterone does not dissolve in said oil; suspending a second quantity of micronized progesterone in said oil to form said pharmaceutical composition.
