This study intended to develop and evaluate isotretinoin (ITR) loaded nanoparticles taking chitosan as a polymer of interest. Ionic crosslinking method was utilized to prepare nanoparticles. Nanoparticles were formulated using varying ratios (chitosan: tripolyphosphate) and evaluated for its size, distribution of size, zeta potential, percentage of ITR entrapped within nanoparticles, in vitro drug release and its stability under accelerated conditions. The prepared nanoparticles (NPs) were spherical, white in color and free flowing, 321± 4.5 nm was the average size of optimized chitosan nanoparticles and it was able to entrap 88.76 ± 3.5%. The outcomes assured vast promise of the CNs of ITR (optimized) in management of acne and also increasing the therapeutic efficacy, thus establish to be a promising, effective and patient compliant formulation. INTRODUCTION Acne, a cutaneous pleomorphic condition of the pilosebaceous unit involving sebum production rate anomaly and described by inflammatory (pustules, nodules and papules) as well as non-inflammatory comedones (closed and/or open)(Knutson, 1974). Regular pus-forming microbes Propionibacterium acnes and Staphylococcus epidermidis are responsible for development of many forms of acne vulgaris(Rawat, Tripathi et al., 2015). It is a pleomorphic disorder and can manifest at any time during life but it most commonly occurs between ages of 12-24 years, accounting effective 85% of population (Cordain, Lindeberg et al., 2002). P. acne is an anaerobic microorganismexisting in acne lesionsthat promotes inflammation through a variety of mechanisms and involved inproducing pro-inflammatory mediators that diffuses through the follicle wall (Itoh, Tsuchida et al., 2014). Prominent in adolescence and puberty, acne is definitely associated with function of sebaceous gland, which stimulate higher secretion of sebum androgenically (Singh, Gangwar et al., 2016).However, the consequential sebaceous

Jerawat  didefinisikan  sebagai  peradangan  kronik  dari  folikel  polisebasea  yang disebabkan  oleh  beberapa  faktor  dengan  gambaran  klinis  yang  khas.  Salah  satu tanaman  yang  dapat  mengatasi  jerawat  yaitu semangka.  Kulit buah semangka (Citrullus lanatus (Thunb.) Matsum & Nakai) memiliki   senyawa antibakteri di antaranya  alkaloid,  fenol,  saponin,  dan  terpenoid.  Dalam penelitian ini ekstrak limbah  kulit  buah semangka diformulasikan   dalam   sediaan   gel.   Tahap   penelitian   yang menggunakan  rancangan  acak  lengkap ini meliputi  penyiapan  dan  pengumpulan simplisia   limbah   kulit   buah   semangka,   ekstraksi,   uji kandungan senyawa, formulasi gel, evaluasi sifat fisik sediaan gel, dan uji aktivitas antibakteri  terhadap  bakteri  Propionibacterium acnes  dan  Staphylococcus  aureus. Ekstraksi yang dilakukan adalah dengan menggunakan metode maserasi dengan penyari kloroform. Uji kandungan senyawa dilakukan dengan menggunakan metode penapisan fitokimia meliputi uji alkaloid, uji triterpenoid, uji fenol, dan uji saponin. Ekstrak kulit buah semangka dengan konsentrasi 5, 10, dan 15% kemudian diformulasikan dengan carbopol 940 dan dilanjutkan dengan evaluasi sifat fisik gel, di antaranya uji organoleptis, uji homogenitas, uji daya sebar, uji daya lekat, uji pH, dan uji viskositas. Uji aktivitas antibakteri dari formulasi ekstrak kulit buah semangka dilakukan dengan menggunakan metode difusi agar. Hasil formulasi terbaik pada formulasi gel menghasilkan gel yang homogen, lekat, menyebar, pH yang cocok dengan kulit, dan memiliki viskositas yang cukup baik. Hasil terbaik dari zona hambat uji antibakteri pada bakteri Propionibacterium acnes yaitu 5,23 mm dan pada bakteri Staphylococcus  aureus yaitu 5,80 mm.

Acne vulgaris é uma das patologias dermatológicas mais comuns na população geral, principalmente em adolescentes e jovens adultos. Esta patologia afeta os folículos pilossebáceos através de processos de hiperqueratose, hipersecreção sebácea, colonização microbiana (Propionibacterium acnes e Malassezia furfur) e mecanismos imunológicos e pode ser descrita tanto como inflamatória (pápulas, pústulas ou nódulos) ou não inflamatória (comedões abertos ou fechados). Apesar de não existir mortalidade associada, existe normalmente significativa morbilidade física e psicológica, como cicatrizes permanentes, baixa autoestima, depressão e ansiedade. A fisiopatologia desta doença é multifatorial, sendo que vários estudos provam a importância de vários fatores genéticos e não genéticos, como diversos mecanismos reguladores endócrinos e a dieta, no aparecimento da acne. Estudos associam a dieta ocidental (carbohidratos hiperglicémicos, leite e lacticínios e gorduras saturadas) e o índice de massa corporal excessivo (excesso de peso e obesidade) ao aparecimento de Acne Vulgaris, sendo que existe evidência do papel da hiperinsulinémia e da resistência à insulina nesta associação. Será assim avaliada nesta dissertação a atual literatura que aborda a fisiopatologia da Acne Vulgaris, com especial foco na relação entre os reguladores endócrinos (androgénios e insulin-like growth factor 1) e reguladores celulares (Forkhead box protein 01, kinase proteica Akt) e os diferentes alimentos da dieta, dando relevância às peculiaridades da dieta ocidental e do seu papel no aparecimento de acne nas diferentes pool´s genéticas mundiais. Será também explorada a relação entre o índice de massa corporal e o aparecimento de acne, bem como a importância das adipocinas na etiologia da acne. O objetivo deste trabalho é contribuir para o melhor conhecimento da fisiopatologia desta interessante e frequente patologia. Sendo uma área muito estudada, torna-se fulcral a existência de artigos de revisão, que compilem, sintetizem e ao mesmo tempo analisem criticamente a literatura científica existente.
