EXCRETORY UROGRAPHY IN PATIENTS PREPARED BY SIMETHICON (ESPUMISAN Â® ) Espumisan Â® is one of the final preparations for oral administration that eliminates gases from the gastrointestinal tract. The drug is in the form of soft capsules gelatin. Each capsule contains 40 mg of simethicon. Espumisan Â® works by dissolving gas bubbles in the chyme, which are then absorbed through the intestinal tract wall or eliminated in the form of gas fluid.
1 Modern diapsids (lizards, snakes, crocodilians, birds) excrete uric acid, which can be excreted as a paste. 2  It is reasonable to suppose that archosaurs (the ancestors of crocodilians, dinosaurs and birds) also excreted uric acid, and therefore were good at conserving water. The hip sockets faced sideways, but the knobs on the femurs were at right angles to the rest of the femur, which therefore pointed downwards. 2  Dinosaurs evolved from archosaurs with this hip arrangement. 3  The hip sockets faced downwards and the knobs on the femurs were in line with the femur.
