Recently, a new lipid based oral capsule was developed to administered insulin. The oral delivery system has a protective lipidic cubic phase encased in an enteric capsule which protects the insulin in the capsule. Bioavailability is the rate of absorption and is the fraction (per cent) of an administered drug that reaches the circulatory system. When a medication is administered intravenously, its bioavailability is 100 per cent. But when it is administered orally its bioavailability is lowered.
