61
Contraindication of metoclopramide
- hypersensitivity - GI bleeding - Bowel occlusion - Ulcer formation - abdominal surgeries - pregnancy - extra pyramidal disorder - epilepsia - childhood - severe renal and hepatic failure
62
What is the pharmokinetics in laxatives
- promote and facilitate bowel evacuation by acting locally to stimulate intestinal peristalsis or to soften bowel contents
