Benzoyl Peroxide and Tretinoin Mechanism, CYP450 Pathways & DailyMed Monograph
1 Indications and usage twyneo: is indicated for the topical treatment of acne vulgaris in adults and pediatric patients 9 years of age and older. TWYNEO is a combination tretinoin, a retinoid, and benzoyl peroxide indicated for the topical treatment of acne vulgaris in adults and pediatric patients 9 years of age and older. ( 1 )
12.1 Mechanism of Action Benzoyl peroxide is an oxidizing agent with bactericidal and keratolytic effects, but the precise mechanism of action is unknown. Tretinoin is a metabolite of vitamin A that binds with high affinity to specific retinoic acid receptors located in both the cytosol and nucleus. Tretinoin activates three members of the retinoic acid (RAR) nuclear receptors (RARα , RARβ, RARγ) which act to modify gene expression, subsequent protein synthesis, and epithelial cell growth and differentiation.
With Predominantly local clearance at target epithelium for Benzoyl Peroxide and Tretinoin residence kinetics and < 5% transdermal or mucosal systemic uptake from Benzoyl Peroxide and Tretinoin bioavailability, Benzoyl Peroxide and Tretinoin undergoes local esterase/enzymatic cleavage of benzoyl peroxide and tretinoin with minimal hepatic cytochrome burden and establishes therapeutic activity over initial local symptom modulation in 30–90 minutes; full tissue response over 1–3 weeks (benzoyl peroxide and tretinoin).
Standard adult regimens span 30 mg/g / 1 mg/g Cream, Maintenance adjustment for Benzoyl Peroxide and Tretinoin based on hepatic/renal clearance. Prescribers screen specifically against 4 contraindications twyneo is contraindicated in patients with a history of hypersensitivity reaction to benzoyl peroxide or any components of twyneo .; history of serious hypersensitivity reaction to benzoyl peroxide or any component of twyneo., while community micro-logs most frequently note nausea (7.3% of reports), headache (6.5% of reports), dizziness (5.9% of reports).
Reconcile eGFR-adjusted medications before escalating Benzoyl Peroxide and Tretinoin in polypharmacy regimens.
Botanical enzyme modulators may alter oral first-pass exposure of Benzoyl Peroxide and Tretinoin; disclose all supplements.
