carbon dioxide producing drugs
A06AX02
Forms & Strengths
- Effervescent powders
- Effervescent granules
- Rectal suppositories generating carbon dioxide
Adult Dosing
- Suppositories: 1 suppository rectally as needed, typically used for prompt bowel evacuation.
- Powders/Granules: Specific doses vary by proprietary formulation, generally dissolved in water prior to ingestion.
Pediatric Dosing
- Safety and efficacy in pediatric populations are not well established; use is generally avoided or restricted to specific specialist recommendations.
Indications
- Constipation (short-term relief)
- Bowel cleansing prior to diagnostic or surgical procedures
Mechanism of Action
- Reaction of constituent ingredients (e.g., sodium bicarbonate and acid generators) upon contact with moisture produces carbon dioxide gas.
- The rapid release of carbon dioxide gas expands the rectum or upper GI tract, stimulating mechanoreceptors and inducing peristalsis and defecation reflex.
Contraindications
- Hypersensitivity to any component
- Gastrointestinal obstruction
- Perforation
- Severe inflammatory bowel disease (e.g., toxic megacolon)
- Undiagnosed acute abdominal pain
Adverse Reactions
- Mild rectal discomfort or burning sensation
- Urge to defecate
- Abdominal cramping or bloating
- Flatulence
Drug Interactions
- May decrease the absorption of concurrently administered oral medications due to accelerated gastrointestinal transit.
- Caution with other agents affecting GI motility.
