Chitosan is a natural polymer which has limited solubility. Chitosan gets solubilized at acidic pH but is insoluble at basic pH. In the present study, carboxymethyl chitosan (CMC) was prepared which shows high swelling in basic pH and thus can delay the drug release and can act as matrix for extended release formulation. CMC was characterized by FTIR and NMR. pH-sensitive hydrogels of theophyll...

Purpose: To develop bioadhesive tablets of diltiazem hydrochloride with a unique combination of bioadhesion and drug release. Method: Tablets were prepared by physical blending of diltiazem hydrochloride with two polymers, viz., carbopol and hydroxylpropyl methyl cellulose in different ratio along with other excipients. A 3 central composite design was employed to optimize the formulations on t...

Purpose: The aim of the present study was to formulate and evaluate miconazole nitrate containing thermosensitive bioadhesive gel for vaginal drug delivery to achieve a better therapeutic efficacy and patient compliance in the treatment for vaginal candidiasis. Method: Here miconazole nitrate (1%) was formulated as a vaginal gel using thermosensitive polymer, pluronic F127 (20%) along with bioa...

Objective: The Losartan potassium mucoadhesive buccal tablet were prepared using mucoadhesive polymers such as Carbopol 940P, pectin, sodium CMC, Sodium alginate, HPMC K4M, HPMC K15M and HPMC K100M in alone and in combination as release retarding agent to prolong the drug release and to avoid first pass metabolism. Methods: The mucoadhesive buccal tablets were prepared by direct compression met...

Purpose: Ofloxacin is a fluoroquinolone with broad-spectrum antibacterial action, used in treatment of systemic and local infections. Ofloxacin is BCS class II drug having low solubility, high permeability with short half-life. The present work was aimed to design, develop and optimize gellified emulsion of Ofloxacin to provide site targeted drug delivery. Transdermal drug delivery will enhance...

UNLABELLED We conducted a phase 1 double-blind randomised controlled trial (RCT) of a HIV-1 envelope protein (CN54 gp140) candidate vaccine delivered vaginally to assess immunogenicity and safety. It was hypothesised that repeated delivery of gp140 may facilitate antigen uptake and presentation at this mucosal surface. Twenty two healthy female volunteers aged 18-45 years were entered into the ...

 Tabir surya adalah sedian kosmetik yang tujuan pemakaiannya untuk menyerap dan menangkal sinar ultraviolet serta menurunkan dampak radiasi uv berbahaya pada kulit. Daun kemangi mengandung senyawa fenolik yaitu flavonoid tanin adanya gugus kromofor maka dapat digunakan sebagai tabir karena mampu UV. Tujuan penelitian mengetahui pengaruh variasi Carbopol 940 terhadap formulas...

The study is related to the formulation and evaluation of mucoadhesive buccal tablets Anastrozole enhance its bioavailability by avoiding 1st pass effect. succeeded in developing containing two layers (mucoadhesive backing layer) a design that permits unidirectional release drug. Tablets were prepared double direct compression method using (carbopol 934) as primary polymer, Sod.alginate, Na CMC...

In this study, the effects of various hydrophilic (HPMC and Carbopol 971) and plastic (Ethylcellulose and Eudragit RL100) polymers on the release profile of diltiazem HCl from matrix tablets were evaluated in-vitro. For this purpose, tablets containing 60 mg of diltiazem HCl along with various amounts of the aforementioned polymers were prepared using the wet granulation technique. Tablets prep...

A transparent clay manufactured using Carbopol® UltrezTM 10 (simplified as U10) was introduced, and its manufacturing processes were briefly described. Both relative transparency (RT) modulation transfer function (MTF) methods used to quantify the optical character variation via soil thickness. The of this new analyzed compared with four traditional materials. thixotropic properties synthetic m...
