In 2019,Asian Journal of Pharmaceutics included an article by Shrivastava, Birendra; Sunil, Mekala; Kishore, V. Sai. COA of Formula: C28H28O3. The article was titled 《Topical combination delivery of benzoyl peroxide and adapalene niosomal gel for acne treatment》. The information in the text is summarized as follows:
Aim and Objective: Adapalene (ADP) is very effective in 0.01% strength, but it causes skin erythema in the applied area. ADP and benzoyl peroxide (BPO) are the most commonly used drugs in treatment of acne. Materials and Methods: The non-ionic surfactants like SPANs are obtained from synthetic sources, and hence the quality is maintained same all the time. The ADP was incorporated into niosomes using SPAN 60 and cholesterol was used as a stabilizer. Various ratios of SPAN 60, cholesterol, Stearic acid, BPO, and ADP were tried and optimized. The present study investigates the effect of niosomal coadministration of BPO and ADP in term of in vitro skin retention study and in vivo antiacne effects. These vesicular carriers, because of their improved percutaneous delivery and better skin retention, have proved to be very useful in enhancing therapeutic index of drugs used for tropical diseases. The niosomal dispersion was incorporated into Carbopol gel. The gel was kept for 3 mo accelerated stability studies. Results and Discussion: The niosomal dispersion was evaluated for various parameters such as vesicle size, shape, and morphol. by transmission electron microscopy. The drug release pattern from gel was evaluated on the basis of in vitro studies and skin irritation studies on rabbit skin. Conclusion: The in vitro study shows sustained release gel effects whereas the in vivo study shows no signs of irritation on the applied skin area. The results came from multiple reactions, including the reaction of 6-(3-(Adamantan-1-yl)-4-methoxyphenyl)-2-naphthoic acid(cas: 106685-40-9COA of Formula: C28H28O3)
6-(3-(Adamantan-1-yl)-4-methoxyphenyl)-2-naphthoic acid(cas:106685-40-9) may be used as a pharmaceutical reference standard for the quantification of the analyte in topical gel formulations using high-performance liquid chromatography technique.COA of Formula: C28H28O3
