Studies on the Absorption of Orally Administered Iron from Sustained-Release Preparations

Abstract

SUSTAINED-release products have been designed to contain in one dosage form the equivalent of several single doses of a drug, which is released to the body over an extended period.

Various types of sustained-release products are now on the commercial market. Some of them have been tested clinically and found to have sustained-release properties whereas others are relatively unavailable and do not show the sustained effect as measured by blood levels and urinary excretion rates of the drug.In studies with . . .
