- Pharmacodynamics
Simethicone decreases the surface tension of gas bubbles in the gastrointestinal tract, facilitating their expulsion.2 It has a short duration of action as it is generally given as needed, and a wide therapeutic index as it is not systemically absorbed.2
- Mechanism of action
Simethicone is a surfactant that decreases the surface tension of gas bubbles in the gastrointestinal tract, more easily allowing gas to exit the body.2
- Absorption
Simethicone is not systemically absorbed and so these data are not readily available.2
- Volume of distribution
Simethicone is not systemically absorbed and so these data are not readily available.2
- Protein binding
Simethicone is not systemically absorbed and so these data are not readily available.2
- Metabolism
Simethicone is not systemically absorbed and so it is not metabolised by the body.2
- Route of elimination
Simethicone is eliminated in the feces.2
- Half-life
Simethicone is not systemically absorbed and so these data are not readily available.2
- Clearance
Simethicone is not systemically absorbed and so these data are not readily available.2
- Adverse Effects
- Improve decision support & research outcomesWith structured adverse effects data, including: blackbox warnings, adverse reactions, warning & precautions, & incidence rates.Improve decision support & research outcomes with our structured adverse effects data.
- Toxicity
Data regarding overdoses with simethicone are rare due to the fact that it is not systemically absorbed.2. In the case of an overdose stop the drug2 and initiate symptomatic and supportive care.
