Influence of pH, Temperature and Impurities on the Solubility of an Active Pharmaceutical Ingredient (API) [PDF]

open access: yes, 2010
Solubility, which defines the liquid /solid equilibrium, is a key parameter to control a crystallization process. This work is focused on the effects of pH, temperature and impurities on the aqueous solubility of an Active Pharmaceutical Ingredient (API).

Effects of F, B2O3 and P2O5 on the solubility of water in haplogranite melts compared to natural silicate melts [PDF]

open access: yes, 1993
The effects of F, B2O3 and P2O5 on the H2O solubility in a haplogranite liquid (36 wt. % SiO2, 39 wt. % NaAlSi3O8, 25 wt. % KAlSi3O8) have been determined at 0.5, 1, 2, and 3 kb and 800, 850, and 900°C.

EFFECT OF SOLUBILITY ENHANCERS ON THE SOLUBILITY OF PARACETAMOL [PDF]

open access: yesIndo American Journal of Pharmaceutical Research, 2013
Solubility plays an important role in dissolution and absorption of drug. Paracetamol has less solubility in aqueous media and belongs to class IV drug according to biopharmaceutical classification system.The aim of present study was to study the effect of different solubility enhancing agents at room temperature on the solubility of paracetamol ...

Controlled Drug Release Asymptotics [PDF]

open access: yes, 1998
The solution of Higushi's model for controlled release of drugs is examined when the solubility of the drug in the polymer matrix is a prescribed function of time. A time-dependent solubility results either from an external control or from a change in pH
