Solubility improvement of progesterone from solid dispersions prepared by solvent evaporation and co-milling [PDF]

, 2020
The aim of this contribution was to evaluate the impact of processing methods and polymeric carriers on the physicochemical properties of solid dispersions of the poorly soluble drug progesterone (PG). Five polymers: hydroxypropyl methylcellulose (HPMC),

Water solubility in aluminosilicate melts of haplogranite composition at 2 kbar [PDF]

, 1992
The compositional dependence of H2O solubility was investigated at 2 kbar and 800°C in haplogranite melts (system SiO2---1bNaAlSi3O8---1bKAlSi3O8 or Qz---1bAb---1bOr).

Controlled Drug Release Asymptotics [PDF]

, 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

Solubility of baclofen in 1-hexyl-4-methylpyridinium bromide + water binary mixtures [PDF]

شیمی کاربردی روز, 2017
In this paper, solubility of baclofen was studied by gravimetric method. The solubility of baclofen was measured in (water + 1-hexyl-4-methylpyridinium bromide) binary mixtures from 293.1 K to 313.1 K under atmosphere pressure.

Soluble Semigroups [PDF]

Journal of the Australian Mathematical Society, 1972
The cancellation law is a necessary condition for a semigroup to be embedded in a group. In general, this condition is not sufficient; necessary and sufficient conditions are rather complicated (see [1]). It is, therefore, of interest to find large classes of semigroups for which the cancellation law is sufficient to ensure embeddability in a group.

Development and Characterization of a Novel Spray-Dried Powder for Inhalation of Cinacalcet HCl Nanoparticles [PDF]

Pharmaceutical Sciences
Background: Administering Cinacalcet HCl (CINA) can be challenging because of its low oral bioavailability (20 to 25%) due mainly to its high first-pass metabolism and poor aqueous solubility.

Hydrocarbon molar water solubility predicts NMDA vs. GABAA receptor modulation. [PDF]

, 2014
BackgroundMany anesthetics modulate 3-transmembrane (such as NMDA) and 4-transmembrane (such as GABAA) receptors. Clinical and experimental anesthetics exhibiting receptor family specificity often have low water solubility. We hypothesized that the molar
