in this study, attempts were made to evaluate the effect of various acrylic acid based carbopols on the release profile of a beta-adrenoreceptor blocking drug, propranolol hcl, from matrix-type tablets invitro. for this purpose, tablets containing 160 mg of propranolol hcl along with various amounts of carbopols 934 (c934), 971 (c971), 974 (c974) and pemulen (pem) were prepared using the wet gr...

Divalproex sodium is the anticonvulsant agents that used in treatment certain types of seizures. The aim present study to formulate and evaluate divalproex bilayer tablet. Sodium Bi-layer tablets (BLT) were prepared by simple blending punching with HPMC, Xanthan Gum, starch glycolate, MCC, PVP, Magnesium stearate. Optimized formulation was designed on basis best immediate release layer sustaine...

The goal of this study was to compare the pharmacokinetics of nicardipine hydrochloride orally disintegrating tablets and β-cyclodextrin inclusion complex with its conventional tablets. Forty-five rats were divided into three groups evaluating the effect of dosage forms on the pharmacokinetics of nicardipine hydrochloride. Blood samples were taken at predefined sampling points 0–24h after medic...

OBJECTIVES Levocetirizine HCl, a second-generation piperazine derivative and H1-selective antihistaminic agent, possesses few side effects. The first objective of the study was to compare and evaluate the taste-masking effect of different ratios of 2-hydroxypropyl-β-cyclodextrin and mannitol on levocetirizine HCl using an inclusion complex and solid dispersion, respectively. The second objectiv...

The objective of the present investigation was to evaluate potential of nanoemulsions as a coating material for the tablets. The nanoemulsion of size less than 100 nm was prepared using a simple and low-energy spontaneous emulsification method. Conventional tablets containing theophylline as a model hydrophilic drug were prepared. The theophylline tablets were coated with the nanoemulsion using...

While the surface tension of a cell membrane, or a plasma membrane, regulates cell functions, little is known about its effect on the conformational changes of the lipid bilayer and hence the resulting changes in the cell membrane. To obtain some insights into the phase transition of the lipid bilayer as a function of surface tension, we used a 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC)...

Many drugs are amphiphiles that, in addition to binding to a particular target protein, adsorb to cell membrane lipid bilayers and alter intrinsic bilayer physical properties (e.g., bilayer thickness, monolayer curvature, and elastic moduli). Such changes can modulate membrane protein function by altering the energetic cost (DeltaG(bilayer)) of bilayer deformations associated with protein confo...

The objective of the present study is to formulate and evaluate roxithromycin tablets employing roxithromycin (ROX) solid dispersions. Dispersions of ROX in mannitol were prepared by different techniques like physical mixing, melting method, melt solvent method, kneading technique and common solvent method with drug and carrier ratio of 1:1, 1:2, 1:4 and 1:9. ROX tablets were formulated employi...

background the dilution and rapid elimination of topically applied drugs due to the flushing action of saliva is a major difficulty in the effort to eradicate infections of oral cavity. utilization a proper delivery system for incorporation of drugs has a major impact on drug delivery and such a system should be formulated for prolonged drug retention in oral cavity. objectives the aim of the p...
