Identification
- Summary
Bazedoxifene is a selective estrogen receptor modulator (SERM) used to treat moderate to severe vasomotor symptoms in menopause and osteoporosis alone or in combination with conjugated estrogens.
- Brand Names
- Duavee, Duavive
- Generic Name
- Bazedoxifene
- DrugBank Accession Number
- DB06401
- Background
Bazedoxifene is a third generation selective estrogen receptor modulator (SERM), developed by Pfizer following the completion of their takeover of Wyeth Pharmaceuticals. In late 2013, Pfizer received approval for bazedoxifene as part of the combination drug DUAVEE in the prevention (not treatment) of postmenopausal osteoporosis. It is approved in the European Union (marketed in Italy and Spain) and Japan as monotherapy. In 2013, the combination product containing conjugated estrogens and bazedoxifene was approved by the FDA for the treatment of moderate to severe vasomotor symptoms associated with menopause, as well as the prevention of postmenopausal osteoporosis in women.

- Pharmacodynamics
Not Available
- Mechanism of action
Bazedoxifene belongs to a class of compounds known as selective estrogen receptor modulators (SERMs). Bazedoxifene acts as both an oestrogen-receptor agonist and/or antagonist, depending upon the cell and tissue type and target genes. Bazedoxifene decreases bone resorption and reduces biochemical markers of bone turnover to the premenopausal range. These effects on bone remodelling lead to an increase in bone mineral density (BMD), which in turn contributes to a reduction in the risk of fractures. Bazedoxifene functions primarily as an oestrogen-receptor antagonist in uterine and breast tissues.
Target Actions Organism AEstrogen receptor antagonistagonistHumans UEstrogen receptor beta Not Available Humans - Absorption
Bazedoxifene is rapidly absorbed with a tmax of approximately 2 hours and exhibits a linear increase in plasma concentrations for single doses from 0.5 mg up to 120 mg and multiple daily doses from 1 mg to 80 mg. The absolute bioavailability of bazedoxifene is approximately 6%.
- Volume of distribution
Following intravenous administration of a 3 mg dose of bazedoxifene, the volume of distribution is 14.7 ± 3.9 l/kg.
- Protein binding
98-99%.
- Metabolism
Glucuronidation is the major metabolic pathway. After peroral application, bazedoxifene is metabolized by UDP-glucuronosyltransferases (UGTs) to bazedoxifene-4'-glucuronide (M4) and bazedoxifene-5-glucuronide (M5).Little or no cytochrome P450-mediated metabolism is evident. The concentrations of this glucuronide are approximately 10-fold higher than those of unchanged active substance in plasma.

- Half-life
~30 hours.
- Clearance
The apparent oral clearance of bazedoxifene is approximately 4 to 5 l/h/kg.

- General Function
- Nuclear hormone receptor. The steroid hormones and their receptors are involved in the regulation of eukaryotic gene expression and affect cellular proliferation and differentiation in target tissues. Ligand-dependent nuclear transactivation involves either direct homodimer binding to a palindromic estrogen response element (ERE) sequence or association with other DNA-binding transcription factors, such as AP-1/c-Jun, c-Fos, ATF-2, Sp1 and Sp3, to mediate ERE-independent signaling. Ligand binding induces a conformational change allowing subsequent or combinatorial association with multiprotein coactivator complexes through LXXLL motifs of their respective components. Mutual transrepression occurs between the estrogen receptor (ER) and NF-kappa-B in a cell-type specific manner. Decreases NF-kappa-B DNA-binding activity and inhibits NF-kappa-B-mediated transcription from the IL6 promoter and displace RELA/p65 and associated coregulators from the promoter. Recruited to the NF-kappa-B response element of the CCL2 and IL8 promoters and can displace CREBBP. Present with NF-kappa-B components RELA/p65 and NFKB1/p50 on ERE sequences. Can also act synergistically with NF-kappa-B to activate transcription involving respective recruitment adjacent response elements; the function involves CREBBP. Can activate the transcriptional activity of TFF1. Also mediates membrane-initiated estrogen signaling involving various kinase cascades. Essential for MTA1-mediated transcriptional regulation of BRCA1 and BCAS3 (PubMed:17922032). Maintains neuronal survival in response to ischemic reperfusion injury when in the presence of circulating estradiol (17-beta-estradiol/E2) (By similarity)

Essential for the elimination and detoxification of drugs, xenobiotics and endogenous compounds (PubMed:18177842). Involved in the glucuronidation of calcidiol, which is the major circulating form of vitamin D3 essential for the regulation of calcium and phosphate homeostasis (PubMed:24641623). Also glucuronidates the biologically active form of vitamin D3, calcitriol, probably leading to its biliary transport and intestinal reabsorption (PubMed:18177842)
