abstract the objective of present study was to evaluate pharmacokinetic parameters of dibudipine phytosolve after oral administration in rats. the solubility test was carried out to select suitable oily solvent for dibudipine. phytosolve formulation was prepared with a medium chain triglyceride (mct) oil (20%), soybean phospholipids (5%) and a 70% fructose solution (75%). the effect of polyol c...

solubility of hydrocarbons in water is important due to ecological concerns and new restrictions on the existence of organic pollutants in water streams. also, the creation of a thermodynamic model has required an advanced study of the phase equilibrium between water (as a basis for the widest spread muds and amines) and gas hydrocarbon phases in wide temperature and pressure ranges. therefore,...

The solubility of triclinic calcium pyrophosphate dihydrate (CPPD) crystals was measured under varying conditions using 45Ca-labeled crystals, expressing solubility as micromoles per liter of 45Ca in solution. In a 0.1-M Tris-HC1 buffer pH 7.4, the solubility of accurately sized CPPD crystals (37-20mum) was 60muM with maximal solubility being attained after about 8 h incubation at 37degreeC. Re...

The competitive inclusion complexations in the ternary phenacetin/competitors/beta-cyclodextrin (beta-CyD) systems were investigated by the solubility method, where m-bromobenzoic acid (m-BBA) and o-toluic acid (o-TA) were used as competitors. The solubility changes of the drug and competitors as a function of beta-CyD concentration in the ternary systems were formulated using their stability c...

Seifert Fibre Groups (SF-Gps) have been introduced and their first derived groups have been worked out in an earlier paper by the author [2,3]. Now we aim to prove that they are residually soluble and residually finite.

The solubility limit data of salts are typically measured in distilled water and not in saline or salt-laden solutions. So, the current study was initiated to measure the solubility limit of major salts in different concentration of NaCl solutions and was compared to the solubility limit of the same salt to that in real seawater solution. A major finding from the experimental results was that t...

G. Ma, B. S. Levine, D. J. Lavrich Merck & Co., Inc. Purpose Amorphous solid dispersions have been increasingly used to enhance the bioavailability for poorly soluble drugs. Dissolution method development for these formulations has faced challenges due to their unstable super saturation state in aqueous media. Whether the dissolution sink condition should be based on API crystalline solubility ...
