abstract |
Described are pharmaceutical compositions comprising at least one steroidal drug such as a progestin (e.g. drospirenone, progesterone, eplerenone, etonogestrel) and/or an estrogen (estradiol and esters thereof) in molecularly dispersed form. The composition comprises a steroidal drug, preferably drospirenone, which is present in the composition in a non-particulate form. Preferably, the drug is present in a dissolved state in the excipient. The molecularly dispersed drug will be released very fast as dissolution takes place instantly when the dosage unit has disintegrated. Also described are methods for preparing the pharmaceutical compositions and methods of using the compositions. |
