Validação de método analítico por cromatografia líquida de alta eficiência para doseamento do adapaleno em suspensões de nanocápsulas

Abstract: Recebido em 27/10/10; aceito em 22/2/11; publicado na web em 12/5/11 VALIDATION OF ANALYTICAL METHOD BY HPLC FOR DETERMINATION OF ADAPALENE IN SUSPENSIONS OF NANOCAPSULES. Adapalene is a retinoid drug often used for disorders of the skin, mainly acne. In this work, an analytical method for the quantification of adapaleno in suspensions of nanocapsules by HPLC was developed and validated. The method was linear in the range of 10-30 μg mL -1 , with a good correlation coefficient (r = 0.994). Precision and accura… Show more

“…According to the European Pharmacopoeia 7 th edition, high performance liquid chromatography (HPLC) determination of adapalene is performed by using a phenyl column (column length: 250 mm; column diameter: 4.6 mm; particle size: 5 µm) and mobile phase consisting of glacial acetic acid, water, acetonitrile and tetrahydrofuran. 7 Several HPLC methods with UV detection for the determination of adapalene in gel topical formulations, [8][9][10][11] suspensions of nanocapsules 12 and in vitro release studies of adapalene from cream formulation 13 have been reported so far. Rühl and Nau presented a method for the determination of adapalene and retinol in biological samples that combines solid-phase extraction and HPLC with UV and fluorescence detection.…”

“…Após o desenvolvimento de um método e antes de sua aplicação na análise de amostras de interesse, o mesmo precisa ser validado, de forma que, nas condições em que será utilizado, gere os resultados esperados. 26,27 Consequentemente, o objetivo deste trabalho foi desenvolver e validar métodos analíticos para a determinação dos ácidos glicirrízico e salicílico e da cafeína em nanopartículas de quitosana e alginato de sódio obtidas através da técnica de complexação de polieletrólitos. …”
