The drugs are classified in BCS on the basis of solubility and permeability. Solubility class boundaries are based on the highest dose strength of an immediate release product. A drug is considered highly soluble when the highest dose strength is soluble in 250 ml or less of aqueous media over the pH range of 1 to 6.8.
The tables below provides information on the variation of solubility of different substances (mostly inorganic compounds) in water with temperature, at one atmosphere pressure. Units of solubility are given in grams of substance per 100 millilitres of water (g/(100 mL)), unless shown otherwise. The substances are listed in alphabetical order.
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
[12] Gramicidin mixture is a crystalline solid. Its solubility in water is minimal, 6 mg/L, and it may form colloidal suspensions. It is soluble in small alcohols, acetic acid, pyridine, poorly soluble in acetone and dioxane, and practically insoluble in diethylether and hydrocarbons. [1]
In chemistry, the common-ion effect refers to the decrease in solubility of an ionic precipitate by the addition to the solution of a soluble compound with an ion in common with the precipitate. [1] This behaviour is a consequence of Le Chatelier's principle for the equilibrium reaction of the ionic association / dissociation .
The drug, a macrolide (polyhydroxylated lactone), is a member of a structural diverse class of compounds called polyketides with notable chemical mechanism of action. It stabilizes the microtubules of target cells, essentially arresting them at a specific stage in the cell cycle and halting cell division.

The phosphomolybdate ion, [PMo 12 O 40] 3−. Ammonium phosphomolybdate is the inorganic salt of phosphomolybdic acid with the chemical formula (NH 4 ) 3 PMo 12 O 40 . The salt contains the phosphomolybdate anion, a well known heteropolymetalate of the Keggin structural class.
