Fezotan 45 mg | PHARMACOLOGY

Fezolinetant is a neurokinin 3 (NK3) receptor antagonist that blocks neurokinin B (NKB) binding on the kisspeptin/neurokinin B/dynorphin (KNDy) neuron to modulate neuronal activity in the thermoregulatory center. Fezolinetant has high affinity for the NK3 receptor (Ki value of 19.9 to 22.1 nmol/L), which is more than 450-fold higher than binding affinity to NK1 or NK2 receptors.Treatment with fezolinetant did not show any clear trends in sex hormones measured (follicle-stimulating hormone, testosterone, estrogen, and dehydroepiandrosterone sulfate) in menopausal women. Transient decrease of luteinizing hormone (LH) levels was observed at peak concentrations of fezolinetant.

Fezotan 45 mg | PRECAUTIONS & WARNINGS

Hepatic Transaminase Elevation and Hepatotoxicity: Elevations in serum transaminase concentrations greater than 3 times the upper limit of normal (ULN) occurred in the clinical trials. Perform hepatic laboratory tests prior to initiation of Fezolinetant to evaluate for hepatic function and injury. Patient should not start Fezolinetant if the concentration of alanine aminotransferase (ALT) or aspartate aminotransferase (AST) is equal to or exceeds 2 times the ULN or if the total bilirubin is elevated (for example, equal to or exceeds 2 times the ULN) for the evaluating laboratory. Patient should perform follow-up hepatic laboratory tests monthly for the frst 3 months, at 6 months, and 9 months after initiation of therapy.
