DESP meaning in Medical ?

Fosfestrol, sold under the brand name Honvan and also known as diethylstilbestrol diphosphate (DESDP), is an estrogen medication which is used in the treatment of prostate cancer in men. It is given by slow intravenous infusion once per day to once per week or by mouth once per day.

Side effects of fosfestrol include nausea and vomiting, cardiovascular complications, blood clots, edema, and genital skin reactions, among others. Fosfestrol is an estrogen, and hence is an agonist of the estrogen receptor, the biological target of estrogens like estradiol. It acts as a prodrug of diethylstilbestrol.

Fosfestrol was patented in 1941 and was introduced for medical use in 1955. It was previously marketed widely throughout the world, but now remains available in only a few countries.
