Adult Studies: In a double-blind study of three different dosing regimens of ZOFRAN Injection, 0.015 mg/kg, 0.15 mg/kg, and 0.30 mg/kg, each given three times during the course of cancer chemotherapy, the 0.15-mg/kg dosing regimen was more effective than the 0.015-mg/kg dosing regimen.
Peristaltic movement comprises relaxation of circular smooth muscles, then their contraction behind the chewed material to keep it from moving backward, then longitudinal contraction to push it forward. Earthworms use a similar mechanism to drive their locomotion, and some modern machinery imitates this design.
The functions of peristalsis and segmentation are different. Peristalsis-Propels the contents of the lumen onward, one way motion, moves food through a sphincter into the stomach, symmetrical contraction and relaxation of muscles, occurs in all parts of the GI.he functions of peristalsis and segmentation are different.
