Modern drug testing and design includes experimental in vivo and in vitro measurements, combined with in silico computations that enable prediction of the drug candidate’s ADMET (adsorption, distribution, metabolism, elimination and toxicity) properties in the early stages of drug discovery. Recent estimates place the discovery and development cost of a small drug molecule close to US $1.3 bill...

One of the biggest challenges faced by pharmaceutical scientists is poor solubility and bioavailability of new chemical entities (NCEs). According to BCS classification; approximately 25% of all compounds are classified as highly soluble and permeable. Nearly 40% of the new chemical entities currently being discovered are lipophilic so poorly water soluble drugs. BCS Class II and Class IV have ...

Objective(s): In a new approach, following the development in metal oxide chemistry, the ibuprofen as low water soluble nonsteroidal anti-inflammatory drug diffused into synthetic sol-gel derived nano porous g-alumina by an impregnation method in order to increase the solubility and control the drug release in physiological environment. Methods: Sol-gel m...

Pharmaceutical research is focused in designing novel drug delivery systems to improve the bioavailability of poorly water soluble drugs. Self-microemulsifying drug delivery systems, one among the lipid-based dosage forms were proven to be promising in improving the oral bioavailability of such drugs by enhancing solubility, permeability and avoiding first-pass metabolism via enhanced lymphatic...

Snakehead fish extract has been recognized for its potential in healing postoperative wounds and burns. The contains albumin, which aids tissue formation processes. To create a high-quality wound drug, the needs to be formulated into concentrated form combined with solvent that can effectively dissolve active substances. Understanding solubility profile of composition is crucial this purpose. T...

The solubility behaviour of drug is one of the most challenging aspects in formulation development. Thus a greater understanding of dissolution and absorption behaviour of drug with low aqueous solubility is required to successfully formulate them into more soluble and hence bioavailable drug product. Therefore different approaches are being explored to enhance the solubility of poorly water so...

As many substances are poorly soluble in water and thus possess decreased bioavailability, creating orally administered forms of these substances is a challenge. The objective of this study was to determine whether the solubility of megestrol acetate, a Biopharmaceutical Classification System (BCS) class II drug, can be improved by using a newly-synthesized surfactant (Rofam 70: a rapeseed meth...

the aim of this study was to design orally disintegrating tablets of olanzapine and to complex olanzapine with 2-hydroxypropyl-β- cyclodextrin with special emphasis on disintegration and dissolution studies. phase solubility studies demonstrated the formation of 1:1 molar inclusion complex by kneading method. tablets were prepared by using superdisintegrants namely, sodium starch glycolate, cro...

Hydrochlorothiazide is a common diuretic antihypertensive drug of the thiazide family. Its poor aqueous solubility is one of the reasons for its limited bioavailability after oral administration. This work aimed at the development of a hydrochlorothiazide:β-cyclodextrin (HTZ:β-CD) pharmaceutical composition in order to improve water solubility and bioavailability of the drug. The HTZ:β-CD compl...

The solubility behavior of drugs remains one of the most challenging aspects in the formulation development. Although there was a great interest in solid dispersion systems during the past four decades to increase solubility by improving dissolution rate and bioavailability of poorly soluble drugs; there commercial use has been very limited, primarily because of manufacturing difficulties and v...
