药理

Indication	Used orally for the treatment of skin manifestations of cutaneous T-cell lymphoma (CTCL) in patients who are refractory to at least one prior systemic therapy. Also used topically for the treatment of skin lesions in early (stage IA and IB) CTCL in patients who experience refractory or persistent disease with the use of other therapies or are intolerant of other therapies.
Pharmacodynamics	Bexarotene is a member of a subclass of retinoids that selectively activate retinoid X receptors (RXRs). These retinoid receptors have biologic activity distinct from that of retinoic acid receptors (RARs). Bexarotene is indicated for the treatment of cutaneous manifestations of cutaneous T-cell lymphoma in patients who are refractory to at least one prior systemic therapy. Bexarotene selectively binds and activates retinoid X receptor subtypes (RXR_α, RXR_β, RXR_γ). RXRs can form heterodimers with various receptor partners such as retinoic acid receptors (RARs), vitamin D receptor, thyroid receptor, and peroxisome proliferator activator receptors (PPARs). Once activated, these receptors function as transcription factors that regulate the expression of genes that control cellular differentiation and proliferation. Bexarotene inhibits the growth in vitro of some tumor cell lines of hematopoietic and squamous cell origin. It also induces tumor regression in vivo in some animal models.
Mechanism of action	Bexarotene selectively binds with and activates retinoid X receptor subtypes. There are three subtypes in total: RXR_α, RXR_β, RXR_γ. The exact mechanism of action of bexarotene in the treatment of CTCL is unknown but the drug has activity in all clinical stages of CTCL.

药物相互作用

Drug	Interaction
Conivaptan	Conivaptan may increase the serum concentration of CYP3A4 substrates such as bexarotene. Upon completion/discontinuation of conivaptan, allow at least 7 days before initiating therapy with drugs that are CYP3A4 substrates. Consider therapy modification.
Demeclocycline	Tetracycline derivatives like demeclocycline may enhance the adverse/toxic effect of Retinoic Acid Derivatives. Due to the risk of developing pseudotumor cerebri (also known as intracranial hypertension), avoid this combination of drugs if possible. If used concomitantly, monitor for evidence of this interaction (eg, dizziness, diplopia, headache).
Desogestrel	Bexarotene may decrease the serum concentration of Contraceptives (Progestins). Since bexarotene is teratogenic and can lower serum concentrations of desogestrel, it is advised that women of childbearing potential use two forms of contraception (including at least one non-hormonal form).
Doxycycline	Tetracycline derivatives like doxycycline may enhance the adverse/toxic effect of Retinoic Acid Derivatives. Due to the risk of developing pseudotumor cerebri (also known as intracranial hypertension), avoid this combination of drugs if possible. If used concomitantly, monitor for evidence of this interaction (eg, dizziness, diplopia, headache).
Drospirenone	Bexarotene may decrease the serum concentration of Contraceptives (Progestins). Since bexarotene is teratogenic and can lower serum concentrations of drospirenone, it is advised that women of childbearing potential use two forms of contraception (including at least one non-hormonal form).
Ethynodiol Diacetate	Bexarotene may decrease the serum concentration of Contraceptives (Progestins). Since bexarotene is teratogenic and can lower serum concentrations of ethynodiol diacetate it is advised that women of childbearing potential use two forms of contraception (including at least one non-hormonal form).
Etonogestrel	Bexarotene may decrease the serum concentration of Contraceptives (Progestins). Since bexarotene is teratogenic and can lower serum concentrations of etonogestrel, it is advised that women of childbearing potential use two forms of contraception (including at least one non-hormonal form).
Gemfibrozil	Gemfibrozil may increase the serum concentration of bexarotene. This combination should be avoided.
Levonorgestrel	Bexarotene may decrease the serum concentration of Contraceptives (Progestins). Since bexarotene is teratogenic and can lower serum concentrations of levonorgestrel, it is advised that women of childbearing potential use two forms of contraception (including at least one non-hormonal form).
Medroxyprogesterone	Bexarotene may decrease the serum concentration of Contraceptives (Progestins). Since bexarotene is teratogenic and can lower serum concentrations of medroxyprogesterone, it is advised that women of childbearing potential use two forms of contraception (including at least one non-hormonal form).
Minocycline	Tetracycline derivatives like minocycline may enhance the adverse/toxic effect of Retinoic Acid Derivatives. Due to the risk of developing pseudotumor cerebri (also known as intracranial hypertension), avoid this combination of drugs if possible. If used concomitantly, monitor for evidence of this interaction (eg, dizziness, diplopia, headache).
Norelgestromin	Bexarotene may decrease the serum concentration of Contraceptives (Progestins). Since bexarotene is teratogenic and can lower serum concentrations of norelgestromin, it is advised that women of childbearing potential use two forms of contraception (including at least one non-hormonal form).
Norethindrone	Bexarotene may decrease the serum concentration of Contraceptives (Progestins). Since bexarotene is teratogenic and can lower serum concentrations of norethindrone, it is advised that women of childbearing potential use two forms of contraception (including at least one non-hormonal form).
Norgestimate	Bexarotene may decrease the serum concentration of Contraceptives (Progestins). Since bexarotene is teratogenic and can lower serum concentrations of norgestimate, it is advised that women of childbearing potential use two forms of contraception (including at least one non-hormonal form).
Tetracycline	Tetracycline may enhance the adverse/toxic effect of Retinoic Acid Derivatives. Due to the risk of developing pseudotumor cerebri (also known as intracranial hypertension), avoid this combination of drugs if possible. If used concomitantly, monitor for evidence of this interaction (eg, dizziness, diplopia, headache).
Tigecycline	Tigecycline may enhance the adverse/toxic effect of Retinoic Acid Derivatives. The development of pseudotumor cerebri (intracranial hypertension) is of particular concern. Avoid this combination.
Vitamin A	Bexarotene increases the risk of vitamin A toxicity. Avoid vitamin A supplementation while taking bexarotene.
