The main aim of the study was to develop and statistically optimize the proniosomal gel for enhanced transdermal delivery using 3(2) factorial designs to investigate the influence of both non-ionic surfactant and cholesterol to maximize the entrapment efficiency and flux. The concentration of non-ionic surfactant and cholesterol were taken as independent variables, while entrapment efficiency a...

Galantamine hydrobromide (GH) is an effective drug for Alzheimer's disease. It is currently delivered via the oral route, and this might cause nausea, vomiting, and gastrointestinal disturbance. In the present work, GH was formulated in a gel-type drug reservoir and then optimized by using response surface methodology (RSM) based on central composite design. This optimization study involved thr...

In this study the pressure-drop, mean and rms axial velocity data are measured using a differential pressure transducer and a laser Doppler anemometer for the flow of Newtonian and non-Newtonian fluids in a concentric annular pipe (radius ratio =0.5) at various Reynolds numbers encompassing the laminar, transitional and turbulent regimes. Three different fluids are utilized; a semi-rigid shear-...

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 ...
