Contents • • • • • • BCS classes [ ] According to the Biopharmaceutical Classification System (BCS) drug substances are classified to four classes upon their solubility and permeability: • Class I - high, high • Example: • Those compounds are well absorbed and their absorption rate is usually higher than excretion. • Class II - high permeability, low solubility • Example:,,,, • The of those products is limited by their solvation rate. A correlation between the bioavailability and the solvation can be found. • Class III - low permeability, high solubility • Example: • The absorption is limited by the permeation rate but the drug is solvated very fast. If the formulation does not change the permeability or gastro-intestinal duration time, then class I criteria can be applied.

Bcs Classification Of Drugs
• Class IV - low permeability, low solubility • Example: • Those compounds have a poor bioavailability. Usually they are not well absorbed over the intestinal mucosa and a high variability is expected. Definitions [ ] The drugs are classified in BCS on the basis of solubility, permeability, and dissolution.
