Befativan(WELIREG) is an innovative drug that offers a new option for the treatment of von Hippel-Lindau (VHL) syndrome. While understanding the drug use and adverse reactions of its special population, it is also important to understand its mechanism of action. The following will introduce in detail the precautions for taking Belzutifan and its mechanism of action.

Is there anything to pay attention to when taking Belzutifan (welireg)?

When taking Belzutifan, patients need to follow certain medication instructions and precautions to ensure the best effect of the drug.

Dosage and frequency of medication

The recommended dose of Belzutifan is 120 mg orally once daily. Patients should take it at the same time each day, with or without a meal. If a dose is missed, it should be retaken as soon as possible on the same day and the normal daily dose schedule should be resumed.

Medication for special populations

Pregnant and lactating women, as well as men and women of childbearing potential, need to be especially careful when using Belzutifan. Pregnant women and women who may become pregnant should be informed about the potential risks of the drug to the fetus. Breastfeeding women should refrain from breastfeeding during treatment and for 1 week after the last treatment. Women of childbearing potential and their partners should use effective contraception.

Adverse reactions interact with drugs

Taking Belzutifan may cause adverse reactions such as decreased hemoglobin, anemia, and fatigue. In addition, caution should be exercised when using drugs such as UGT2B17 or CYP2C19 inhibitors to avoid drug interactions. Patients should learn more about drug interactions before use and take medication under the guidance of a doctor.

mechanism of action of taking Belzutifan(welireg)

Understanding the mechanism of action of Belzutifan can help patients better understand and use the drug.

The main target of action

The primary target of Belzutifan is HIF-2α (hypoxia-inducible factor-2α). HIF-2α plays a key role in lesion growth and angiogenesis in patients with VHL syndrome.

Inhibits lesion growth and angiogenesis

By inhibiting the activity of HIF-2α, begetevan is able to slow down the growth rate of lesions in patients with VHL syndrome and reduce the formation of neovascularization. This mechanism of action makes Belzutifan an an effective drug for the treatment of lesions associated with VHL syndrome.

By inhibiting the activity of HIF-2α, Belzutifan plays a role in inhibiting lesion growth and angiogenesis, which provides a new treatment option for patients with VHL syndrome.
