Tretinoin and Benzoyl Peroxide
A simple, sensitive, spectrophotometric method in UV region has been developed for the simultaneous estimation of benzoyl peroxide and tretinoin in bulk and semi solid dosage form (cream). Standard solution of benzoyl peroxide shows maximum absorbance at 234.8 nm and tretinoin shows maximum absorbance at 348.6 nm. Beer’s Lamberts law is obeyed in concentration range 1-9 μg/ml for tretinoin with...
متن کاملComparing a novel solubilized benzoyl peroxide gel with benzoyl peroxide/clindamycin: final data from a multicenter, investigator-blind, randomized study.
INTRODUCTION A solubilized 5% BPO gel has been developed to enhance the bioavailability, follicular penetration, and efficacy of BPO. METHODS Sixty-five patients with moderate facial acne vulgaris were randomly assigned to apply solubilized 5% BPO gel to one facial side and 5% BPO/1% clindamycin to the contralateral side, twice daily for four or 12 weeks. RESULTS The solubilized BPO gel res...
متن کاملsingle-step synthesis of multi-component spirobarbiturates using ionic liquids and synthesis of substituted pyridine filled with catalysts supported on solid substrate
in this thesis, a better reaction conditions for the synthesis of spirobarbiturates catalyzed by task-specific ionic liquid (2-hydroxy-n-(2-hydroxyethyl)-n,n-dimethylethanaminium formate), calcium hypochlorite ca(ocl)2 or n-bromosuccinimide (nbs) in the presence of water at room temperature by ultrasonic technique is provided. the design and synthesis of spirocycles is a challenging task becaus...
15 صفحه اولEfficacy of benzoyl peroxide (5.3%) emollient foam and benzoyl peroxide (8%) wash in reducing Propionibacterium acnes on the back.
BACKGROUND Topical treatment of acne vulgaris on the back is challenging largely due to the extensive broad surface with difficult to reach areas. A "leave-on" foam is suited for application to the trunk due to ease of application and spreadability. Prior to this trial, no data on Propionibacterium acnes (P. acnes) reduction on the back has existed for any benzoyl peroxide (BP) formulations or ...
متن کاملBenzoyl Peroxide Oxidation Route to the Synthesis of Solvent Soluble Polycarbazole
Carbazole was oxidized by benzoyl peroxide in presence of p-toluenesulfonic acid to polycarbazole salt at room temperature for the first time. Polycarbazole salts were synthesized via solution and emulsion polymerization pathways. Polycarbazole bases were prepared by dedoping from polycarbazole salts. Formation of polycarbazoles was confirmed from infrared, electronic absorption and EDAX spectr...
