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 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.
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.
p-Toluenesulfonic acid (PTSA, pTSA, or pTsOH) or tosylic acid (TsOH) is an organic compound with the formula CH 3 C 6 H 4 SO 3 H.It is a white extremely hygroscopic solid that is soluble in water, alcohols, and other polar organic solvents. [6]
The drug apparent permeability (P app) is calculated by normalizing the drug flux (j) over the initial concentration of the API in the donor compartment (c 0) as: Equation 2: = / Dimensionally, the P app represents a velocity, and it is normally expressed in cm/sec. The highest is the permeability, the highest is expected to be the ...
[21] [36] Lacosamide is a functionalized amino acid molecule that has high solubility in water and DMSO, with a solubility of 20.1 mg/mL in phosphate-buffered saline (PBS, pH 7.5, 25 °C). [21] [37] The molecule has six rotatable bonds and one aromatic ring. Lacosamide melts at 143-144 °C and boils at 536.447 °C at a pressure of 760 mmHg. [30 ...
Diacerein , also known as diacetylrhein, is a slow-acting medicine of the class anthraquinone used to treat joint diseases such as osteoarthritis. [1] It works by inhibiting interleukin-1 beta . An updated 2014 Cochrane review found diacerein had a small beneficial effect on pain. [ 2 ]
