Release from capsules

The concentration of myoglobin appearing in the release buffer was measured spectrophotometrically by absorbance at 410 nm. Release of myoglobin from encapsulated liposomes (- -) is compared with myoglobin released from capsules containing free myoglobin (-x-). [Pg.188]

This release was compared with release from capsules containing... [Pg.188]

Figure 7. Release profile from sonicated capsules. Samples that were to be treated with sonic energy were placed in the polypropylene cages and immersed in 10 ml of physiological saline in scintillation vials. The vials were subjected to 3 minutes of sonication at 4 C in a sonic bath. The capsules were then transferred to fresh buffer and the release of myoglobin was followed (- -) and compared with release from capsules containing free myoglobin (-x-). Figure 7.

Generally drugs are released from capsules faster than from tablets because the powdered drug has not been compressed and can dissolve at faster rates. The gelatin (a protein) is acted upon rapidly by the enzymes of the GI tract, which permits gastric juices to penetrate and reach the contents to promote dissolution. [Pg.21]
