Usage
Dimethicone + Pancreatin is prescribed for individuals with exocrine pancreatic insufficiency (EPI), a condition where the pancreas doesn’t produce enough enzymes to digest food properly. This combination also addresses symptoms like indigestion, bloating, and flatulence associated with EPI or other gastrointestinal issues. It is classified as a digestive enzyme supplement and antiflatulent.
The pancreatin component provides the necessary enzymes (amylase, lipase, and protease) for breaking down carbohydrates, fats, and proteins, respectively. Dimethicone, an antifoaming agent, reduces the surface tension of gas bubbles in the digestive tract, facilitating their expulsion and relieving bloating.
Alternate Names
This combination doesn’t have a universally recognized international nonproprietary name (INN). It’s often referred to as pancreatin/simethicone (simethicone is another name for dimethicone). Brand names vary depending on the region and manufacturer. Some examples include Atmocreas and Crevat.
How It Works
Pharmacodynamics: Pancreatin supplements the deficient pancreatic enzymes, enabling digestion of food in the duodenum. Dimethicone decreases surface tension of gas bubbles, promoting their coalescence and subsequent expulsion.
Pharmacokinetics: Pancreatin’s enzymes are not absorbed systemically; they act locally in the gastrointestinal tract. Dimethicone is also not absorbed; it’s eliminated in the feces.
Mode of Action: Pancreatin’s enzymes act on specific substrates: amylase on starches, lipase on fats, and protease on proteins, breaking them down into smaller molecules for absorption. Dimethicone alters the physical properties of gas bubbles, not affecting gas production itself. No receptor binding, enzyme inhibition, or neurotransmitter modulation is involved in the action of this combination.
Elimination: Pancreatin is eliminated through the digestive process. Dimethicone is eliminated unchanged in feces.
Dosage
Standard Dosage
Adults: One to two tablets/capsules with each meal containing 8,000 to 24,000 USP units of lipase activity or as directed by physician. The dose may be increased gradually based on symptom relief and tolerance.
Children: Dosage is individualized based on age, weight, and the severity of pancreatic insufficiency. Consultation with a pediatrician or pediatric gastroenterologist is essential.
Special Cases:
- Elderly Patients: Start with a lower dose and increase gradually as tolerated, monitoring for gastrointestinal side effects.
- Patients with Renal Impairment: No specific dose adjustment is typically required.
- Patients with Hepatic Dysfunction: No specific dose adjustment is typically required.
- Patients with Comorbid Conditions: Caution should be used in patients with gout, cystic fibrosis, asthma, or pre-existing pancreatic conditions.
Clinical Use Cases
The combination isn’t typically used in clinical settings such as intubation, surgical procedures, mechanical ventilation, ICU use, or emergency situations. It’s primarily used for digestive support in outpatient settings.
Dosage Adjustments
Dosage adjustments may be based on individual response and tolerance.
Side Effects
Common Side Effects
Nausea, stomach pain, diarrhea, constipation, bloating.
Rare but Serious Side Effects
Allergic reactions (rare), fibrosing colonopathy (in patients with cystic fibrosis).
Long-Term Effects
Potential for reduced absorption of folic acid and iron with prolonged use.
Adverse Drug Reactions (ADR)
Severe allergic reactions requiring immediate medical attention.
Contraindications
Known hypersensitivity to any component of the medication, acute pancreatitis, recent intestinal surgery, intestinal blockage, or extensive intestinal scarring. Hypersensitivity to pork products (some formulations use porcine enzymes).
Drug Interactions
Antacids containing magnesium or aluminum, proton pump inhibitors, H2 receptor blockers, some antibiotics (tetracycline, ciprofloxacin), iron supplements, acarbose, quinapril, and calcium supplements. Folic acid and iron absorption might be affected, so spacing doses is recommended. Alcohol may worsen pre-existing pancreatic conditions.
Pregnancy and Breastfeeding
Pregnant or breastfeeding women should consult their doctor before use. Safety during pregnancy and breastfeeding isn’t fully established.
Drug Profile Summary
