Ronvan® fosfestrol tetrossódico
Rendering and Display
injectable Solution – each ampoule of 5ml contains 300mB of fosfestrol tetrassódico corresponding to 250mg of diphosphate
Tablets -each tablet contains 120mg of fosfestrol tetrassódico corresponding to 100mg of e dietilestilbestrol.
RONVAN is presented in a box with ten vials of 5 ml box with 50 tablets.
Pharmacology – fosfestrol and transformed into dietilestilbostrol , citostaticamente active , through sdoramento enzimatico
groups of phosphoric acid. Odietilestilbestrol is quickly inactivated in the serum and in the tissues which binds to proteins. In carcinomade prostate and their metastases are quite favorable conditions for the unfolding of enzyme molecule fosfestrol, that is, the pH around 5.5 with high activity of acid phosphatase. Thus, a large amount of dieblestilbestrol free and slightly soluble is released intracelularmente,depositing in the tissues tumor.It is in this particuaridade biochemistry of prostatic tissue that resides agreat specificity organic effect RONVAN.
Pharmacokinetic – the phosphatases are able to desfosforilar e dietilestilbestrol in vitro and in vivo. In the blood, the
dietilestilbestrol livrejápode serdetectado five minutes after the injection of fosfestrol tetrassódico. This breakdown enzyme
promotes the release of monophosphate dietilestilbestrol in the body. Proved if also the release of monotosfato
dedietilestilbestrol in vitro. The metabolite main fosfestrol, that is, the dietilestilbestrol, represents the way citostaticamente active
prepared. The rest of the metabolizacão occurs rapidly by conjugation with glicuronato or sulfate.
