Antipyretic and analgesic effects. Its mechanism of action is related to the inhibition of prostaglandin synthesis. Its antipyretic effect is similar to that of acetylsalicylic acid, but its analgesic effect is weaker, it has no anti-rheumatic effect, and has no effect on platelets and coagulation mechanisms.

After oral or enema administration, it is not digested and absorbed. In the intestines, especially near the colon, the calcium ions of this drug are exchanged with potassium ions in the intestines. The polystyrene sulfonic acid resin itself does not change and is excreted from the feces as it is, resulting in the potassium in the intestines being removed from the body.

This product is a semi-synthetic progesterone derivative, which has a certain inhibitory effect on hormone-dependent tumors. Its mechanism of action is the same as that of medroxyprogesterone, which may be through the influence on the secretion of pituitary gonadotropin, controlling the development and growth of ovarian follicles, thereby reducing the production of estrogen. It acts on androgen receptors, preventing their synthesis and reuse, interfering with their binding with estrogen, and inhibiting tumor cell growth. In addition, it can also antagonize glucocorticoid receptors and interfere with the interaction between steroid hormone receptors and regulatory proteins related to cell growth and differentiation.
