1. Mechanism of action of the drug Valiera
Valiera drug includes the ingredient Estradiol, which is classified as the most powerful estrogen hormone in nature. Estradiol and other estrogen hormones in the body have an important role in the development and maintenance of the reproductive system as well as sexual characteristics of a woman. In postmenopausal women, estradiol stops secreting causing vasomotor imbalance as well as temperature regulation, which in turn causes hot flashes, sleep disturbances, excessive sweating and genital atrophy occurs.
Estradiol replacement therapy may help relieve symptoms of estradiol deficiency in postmenopausal women. Most women at this stage often show signs of gradual increase in bone loss due to estradiol deficiency. At that time, the bones become thin, weak and at high risk of fracture, especially in the vertebrae or hip and wrist bones. Signs of osteoporosis in women are also important indications in treatment with estradiol and this therapy is quite effective in reducing bone resorption. Estrogen is used as a supplement in the prevention of osteoporosis but cannot help the bone to restore the lost parts.
When Valiera enters the body, the Estradiol component will be well absorbed through the skin, mucous membranes and gastrointestinal tract. The drug is also widely distributed in the body and in high concentrations in sex hormone target organs. In the blood, estradiol is about 60% bound to albumin (38% of globulin is bound to sex hormones and about 2% is free). The metabolism of estradiol can be mainly concentrated in the liver and converted to estrone, estriol or other conjugates such as glucuronic or sulfate, glucuronic in the liver.
