Purpose: To develop rosuvastatin calcium-loaded self-nanoemulsifying powder for improved oral delivery of the drug. Methods: Solubility study was carried out in different oils, surfactants and co-surfactants. Based on the solubility study, liquid formulations were prepared using LAS/Capryol 90: Maisine 35-1 as oil phase and Tween 20 with Lutrol E400 as surfactant mixture (Smix). The liquid form...
The present study describes the development and validation of a dissolution method for delapril (DEL) and manidipine (MAN) combination tablets, using a simulated absorption profile based on in vivo data for MAN. The suitable in vitro dissolution profile for this formulation was obtained using 900 mL of citrate buffer pH 3.2 at 37 °C±0.5 °C as dissolution medium and USP apparatus 2 (paddle) at 7...
Studies have shown that when compressing drugs with low aqueous solubility, the solubility of diluents selected is very crucial as it influences the disintegration, dissolution and bioavailability of such drugs. Based on these reports, the present study was undertaken to investigate the effect of some commonly used hydrophilic tablet diluents (lactose, sucrose, mannitol and dextrose) on the in ...
Article history: Received on: 21/03/2016 Revised on: 11/06/2016 Accepted on: 17/07/2016 Available online: 26/09/2016 The objective of the present study was to compare and evaluate the economic benefits and in-vitro bioequivalence of different marketed generic ciprofloxacin tablets against the innovator tablet formulation that are present in the local market of Saudi Arabia. The comparative bioe...
The present investigation includes the preparation of liquid filling formulations for soft gels using an antihypertensive drug, valsartan (VAL), in order to improve its dissolution properties and thereby its bioavailability. Formulations were prepared using excipients like polyethylene glycol 400 (PEG 400), propylene glycol (PG), polyvinylpyrrolidone (PVP K-30), antioxidants, ethanol, and purif...
PURPOSE In vitro disintegration and dissolution are routine methods used to assess the performance and quality of oral dosage forms. The purpose of the current work was to determine the potential for interaction between capsule shell material and a green tea extract and the impact it can have on the release. METHODS A green tea extract was formulated into simple powder-in-capsule formulations...
In the present study, an attempt was made to increase the in vitro dissolution rate of carvedilol (antihypertensive) by cogrinding technique using various carriers, namely lactose, corn starch, treated agar, microcrystalline cellulose. The coground mixtures were prepared using the above excipients in four drug-carrier ratios, viz., 1:1, 1:3, 1:4 and 1:9. The prepared coground mixtures were eval...
Biorelevant in vitro dissolution is a useful technique for qualitative forecasting of the in vivo behavior of a formulation. A biorelevant dissolution medium for simvastatin was developed with a lower concentration of surfactant (0.1% sodium lauryl sulfate, SLS) in the medium as compared with the 0.5% SLS concentration stated in the USP monograph. The slower dissolution rate of simvastatin tabl...
Preparation and in vitro characterization of floating microparticles loaded with cimetidine (FMC) for oral delivery was the objective of this study. Non-solvent addition coacervation technique using hydroxypropylmethylcellulose (HPMC) as the rate controlling polymer was employed to achieve FMC. Three formulations of FMC were prepared and optimized regarding encapsulation efficiency and dissolut...
