| Bioactivity | Simethicone is an orally active defoamer. Simethicone reduces the surface tension of air bubbles in the gastrointestinal tract, causing them to be expelled by vomiting, exhalation or absorption into the bloodstream. Simethicone has potential applications in flatulence and colic[1]. Related Catalog Research Areas >> Others Signaling Pathways >> Others >> Others In Vivo Simethicone (200 mg/kg; oral; single dose) It has gastrointestinal regulatory function in rats [2]. Simethicone (20 mg/kg; oral; single dose) shows jejunal modulating effects in rabbits [3]. Animal Model: Female adult Wistar rats (200-250 g)[2]. Dosage: 50, 100 and 200 mg/kg. Administration: Oral gavage; single dose. Result: Improved colon permeability and hypersensitivity (200 mg/kg). Animal Model: Adult New Zealand White (NZW) rabbits[3]. Result: Improved image quality scores for the jejunum without affecting left kidney, right kidney and gallbladder. References [1]. Voepel-Lewis TD, et al.
