This invention relates to novel pharmaceutical compositions and methods for their preparation containing conjugated estrogens for the treatment of peri-menopausal, menopausal and post-menopausal disorders in women. The novel pharmaceutical compositions comprise a carrier base material and conjugated estrogens formed into a solid unit dosage form possessing a regular incremental release of the medicament upon oral administration. Further, the invention comprises the combination of conjugated estrogens with progestogens in a solid, shaped dosage unit. Specifically, the invention comprises the use of an organic excipient such as high molecular weight hydroxyalkyl alkylcelluloses. The use of an organic excipient such as hydroxypropylmethylcellulose in a stable, solid dosage formulation containing either conjugated estrogens alone or in combination with a progestogen is described.
