Lamotrigine is used in the treatment of CNS disorders, particularly epilepsy; pain; oedema; multiple sclerosis and psychiatric indications including bipolar disorder. Lamotrigine belongs to biopharmaceutical classification systems, BCS class II (Low solubility & High permeability). In addition, it requires immediate therapeutic action hence the main objective of this study is to improve the sol...

Meloxicam (MLX), a non-steroidal anti-inflammatory drug (NSAID) and a selective COX-2 inhibitor is a water insoluble drug (about 12 microg/ml). In order to improve the aqueous solubility of the drug and its dissolution rate, physical mixture and solid dispersions with skimmed milk were prepared and investigated. Enhancement of aqueous solubility of MLX was observed with solid dispersion of the ...

the present study investigates the possibility of using poloxamers as solubility and dissolution rate enhancing agents of poorly water soluble bioactive constituent patchouli alcohol (pa) that can be used for the preparation of immediate release pellets formulation. two commercially available grades poloxamer 188 (p 188) and poloxamer 407 (p 407) were selected, and solid dispersions (sds) conta...

Ibuprofen solid dispersions were prepared by the solvent and fusion-solvent methods using polyethylene glycol (PEG), polyvinylpyrrolidone (PVP), eudragit RS PO, eudragit RL PO and hydroxypropylmethylcellulose (HPMC) as carriers to improve physicochemical characteristics of ibuprofen. The prepared solid dispersions were evaluated for the flowability, solubility characteristics and dissolution be...

This research aimed to develop a supercritical fluid (SCF) technique for preparing a particulate form of itraconazole (ITZ) with good dissolution and bioavailability characteristics. The ITZ particulate solid dispersion was formulated with hydroxypropyl methylcellulose, Pluronic F-127, and L-ascorbic acid. Aggregated particles showed porous structure when examined by scanning electron microscop...

Meloxicam is a non steroidal anti-inflammatory drug, used in the treatment of rheumatoid arthritis and oestoarthritis. It is practically insoluble in water leading to poor dissolution, variations in bioavailability and gastric irritation on oral administration. In order to modulate its gastric side effect and to increase aqueous solubility, physical mixture and solid dispersion of the drug were...

background and objectives: colocynthin is the major active secondary metabolite of colocynth, citrullus colocynthis (l.) schrad, which has been used in traditional and ethno medicine of many countries.  it could be considered as an active marker for quality control of colocynth and its herbal products. analysis and standardization of colocynth and its herbal preparations are a critical issue fo...

Solid dispersions of ibuprofen (IBU) were prepared by solvent evaporation method using polyvinyl pyrrolidone (PVP) and/or sodium lauryl sulphate (SLS). Physicochemical properties of the various solid dispersion systems were determined by differential scanning calorimetry (DSC) and X-ray diffraction (XRD) analysis. The results from dissolution studies indicated that ternary solid dispersion syst...
