Estradiol valerate has been discovered to possess neuropsychotropic activity, e.g., it is an effective anti-depressant having advantageous properties.

Use of estradiol valerate as an anti-depressant

A composite vaginal ring containing a safe and effective amount of a pharmaceutically active medicament, which comprises:

Vaginal ring

Norgestrel, its D- and L-enantiomers and their 17-esters exhibit neuropsychotropic activity when administered in effective dosages to patients exhibiting neuropsychic disturbances of the affective and behavioral type.

Neuropsychotropic agents and their use

A Y-shaped medicated contraceptive IUD for human use having a pair of elastomeric arms rounded at the ends thereof to facilitate insertion and removal, and a base containing protrusions to aid in gripping of the device by the cervix muscles. The device is adaptable to virtually any size human uterus and shows fewer side effects and spontaneous expulsions than known IUD's.

Intrauterine contraceptive device

A composite vaginal ring containing a safe and effective amount of a pharmaceutically active medicament, which comprises: A. a major supporting vaginal ring consisting essentially of a physiologically acceptable synthetic resin and having at least a portion of the annular surface thereof adapted to mate with corresponding minor, medicament-containing vaginal ring segment; and B. at least one minor, medicament-containing vaginal ring segment adapted to mate with the modified annular surface of said major supporting vaginal ring and consisting essentially of a safe and effective amount of a pharmaceutically active amount of a nonionic, lipophilic drug dissolved or uniformly suspended in an elastomeric, cross-linked LTV linear dimethylpolysiloxane resin.
