The present invention relates to pharmaceutical composition comprising steroidal drugs, such as drospirenone, in molecularly dispersed form. Preferably, the compositions are provided as solid, semi-solid or liquid forms, which in turn preferably are adapted for oral administration and preferably to be absorbed from the gastro-intestinal tract. Such compositions are found to have high bioavailability, good chemical stability, and fast in~- vitro dissolution release and can be produced under conditions, which do not require costly equipment or safety guards.
