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.
Solubility in water can be estimated from the number of hydrogen bond donors vs. alkyl sidechains in the molecule. Low water solubility translates to slow absorption and action. Too many hydrogen bond donors, on the other hand, lead to low fat solubility, so that the drug cannot penetrate the cell membrane to reach the inside of the cell.
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.
Calcium dobesilate is a vasoprotective.It is the calcium salt of dobesilic acid.It is a synthetic molecule with the ability to reduce capillary permeability in the body. In Switzerland the drug is sold by the pharmaceutical company OM Pharma under the trade name of Doxium in capsules containing 500 mg of active ingredient.
MADISON, Wis. — A 15-year-old girl who police say killed two people and wounded multiple others at a private Christian school in Wisconsin endured what appeared to be a tumultuous home life ...
The amount of piperine varies from 1–2% in long pepper, to 5–10% in commercial white and black peppers. [ 6 ] [ 7 ] Piperine can also be prepared by treating the solvent-free residue from a concentrated alcoholic extract of black pepper with a solution of potassium hydroxide to remove resin (said to contain chavicine , an isomer of piperine ...
