Fast dissolving tablets of clonazepam were prepared by direct compression method with a view to enhance patient compliance. A 3(2) full factorial design was applied to investigate the combined effect of two formulation variables: amount of crospovidone and microcrystalline cellulose. Crospovidone (2-8% w/w) was used as superdisintegrant and microcrystalline cellulose (20-40% w/w) was used as di...

Chemotherapy research highly prioritizes overcoming the multidrug resistance (MDR) in human tumors. Liposomal formulation of fluoxetine, as a fourth generation chemosensitizer, was constructed and characterized for percent entrapment, release profile, morphology, particle size, zeta potential and stability. Liposomes were prepared using different active loading techniques. The influence of diff...

In this study,formulation of sustained-releasingmatrix tablet of bupropion 150 mg, using hydroxypropylmethylcellu lose(HPMC) 4000cps was evaluatedwith the aim of reducing the frequency of daily dose. The level of HPMC4000 ,polyvinylpyrolidone(PVP) and magnesium stearate(Mg St)was varied based on a 2level 3 factor factorial experimental designusing the release rate of the drug from the matrices ...

presence of available and stable fluoride in a dentifrice formulation is a major requirement for an anti-caries effect. although the available fluoride concentration in iranian dentifrices has been reported in previous studies, there is little information on its stability; which is dependent upon dentifrice formulation. this study was done to assess the fluoride ion concentration and stability ...

Various aqueous and oily diclofenac ophthalmic formulations were subjected to accelerated and long term stability studies. Degradation of diclofenac was found to follow first-order kinetics. Among the aqueous formulations containing preservative, formulation with PMA, PMN, SA, MP/PP and SMS showed diclofenac content above 90% after 6 months of accelerated and 12 months of room temperature stora...

This study investigates the viscous term formulation for the newly developed energy stable flux reconstruction (ESFR) scheme, as an extension to the linear advection flux formulation in the original ESFR scheme. The concept of energy stability for the flux reconstruction approach is put forward. This paper also discusses the formulation of inviscid first derivative flux based on flux reconstruc...

The aim of the present study was to investigate the potential of nanoemulsion formulation for topical delivery of Clobetasol propionate (CP) using algal oil (containing omega-3 fatty acids) as the oil phase. CP has anti-inflammatory, immunomodulatory and antiproliferative activities. However, its clinical use is restricted to some extent due to its poor permeability across the skin. Algal oil w...
