Usage
- Alpha-amylase + Pepsin is prescribed for managing various digestive disorders such as dyspepsia (indigestion), flatulence, bloating, belching, loss of appetite, and abdominal distention. It aids in the breakdown of proteins and carbohydrates, improving digestion and nutrient absorption. It can also be used as a pancreatic enzyme replacement in pancreatic insufficiency.
- Pharmacological Classification: Digestive enzyme preparation.
- Mechanism of Action: This combination medication works by supplementing the body’s natural digestive enzymes. Alpha-amylase breaks down complex carbohydrates (starch and glycogen) into simpler sugars (maltose and glucose), while pepsin breaks down proteins into smaller peptides. This facilitates better absorption of nutrients in the intestines.
Alternate Names
- No widely recognized alternate names exist for this specific combination. It is usually referred to as Alpha-amylase + Pepsin.
- Brand Names: Several brand names market this combination, including Lupizyme Plus, Digeplex, and Enzar. Brand names can vary regionally.
How It Works
- Pharmacodynamics: Alpha-amylase acts in the mouth and small intestine to hydrolyze starches into simpler sugars, promoting carbohydrate digestion. Pepsin, activated by the acidic environment of the stomach, breaks down proteins, thus aiding protein digestion.
- Pharmacokinetics: The combination is administered orally. Alpha-amylase is not absorbed systemically and acts locally in the digestive tract. Pepsin is also primarily active in the stomach lumen. Elimination is mainly through fecal excretion. Specific details on absorption, distribution, metabolism, and excretion for this combination are limited.
- Mode of Action: Alpha-amylase catalyzes the hydrolysis of alpha-1,4-glycosidic linkages in starches. Pepsin, a protease, cleaves peptide bonds in proteins.
- Receptor Binding, Enzyme Inhibition, or Neurotransmitter Modulation: Neither alpha-amylase nor pepsin primarily exerts effects through receptor binding, enzyme inhibition, or neurotransmitter modulation in their digestive roles. They primarily function by direct enzymatic action on dietary substrates within the digestive tract.
- Elimination Pathways: Primarily fecal excretion.
Dosage
Dosage is determined by a physician based on individual patient needs and the formulation used (syrup, capsule, tablet).
Standard Dosage
Adults:
- Dosage varies depending on the formulation. Syrups may be prescribed as 10 ml twice daily after meals, while capsule/tablet dosages are product-specific.
Children:
- Dosages for children should be determined and adjusted by a physician based on the child’s age, weight, and medical condition. Specific pediatric formulations exist.
Special Cases:
- Elderly Patients: Dosage adjustments may be needed based on renal/hepatic function.
- Patients with Renal Impairment: Caution and possible dosage adjustments are needed in cases of severe renal impairment.
- Patients with Hepatic Dysfunction: Caution advised, dosage adjustments may be required in severe cases.
- Patients with Comorbid Conditions: Caution advised in pancreatitis, peptic ulcer disease, gastrointestinal blockages, malabsorption syndromes, and gout. Consult a physician for specific advice.
Clinical Use Cases
This medication is primarily intended for managing digestive problems associated with insufficient enzyme production rather than for the specific clinical scenarios listed below. The cases mentioned below might use amylase and pepsin for other purposes such as the study of these enzymes but the administration of these enzymes to patients is unlikely.
- Intubation: No specific dosage recommendations for intubation.
- Surgical Procedures: No routine usage or dosage recommendations for surgical procedures.
- Mechanical Ventilation: Not typically indicated.
- Intensive Care Unit (ICU) Use: Not routinely used unless specifically indicated for digestive issues.
- Emergency Situations: No use in emergency situations like cardiac arrest or status epilepticus.
Dosage Adjustments
Dose adjustments are based on patient factors such as age, weight, renal/hepatic function, concomitant medications, and the severity of digestive problems. Always follow the physician’s instructions and consult for any adjustments needed.

Popular Combinations
While alpha-amylase and pepsin are commonly combined, other enzymes like papain, bromelain, diastase, and simethicone are sometimes included in combination products to address multiple digestive issues.
Precautions
- Pre-existing medical conditions (pancreatitis, peptic ulcer disease, hepatic/renal impairment) necessitate caution.
- Allergies to pork or other animal-derived products should be considered, as some enzymes may be derived from these sources.
- Pregnancy and breastfeeding: Consult a physician.
- Children and Elderly: Dosage adjustments might be necessary.
- Lifestyle: Limit alcohol and avoid smoking, as these can exacerbate digestive problems.
FAQs (Frequently Asked Questions)
