Olimel Perifer N4e (Valine, Alanine, Arginine, Histidine, Isoleucine, Leucine, Methionine, Phenylalanine, Proline, Serin)

Olimel Perifer N4e provides amino acid supplementation that supports several clinical situations where protein intake is compromised.

• Malnutrition: Helps restore nitrogen balance and supports tissue repair.
• Post‑operative recovery: Contributes to wound healing and muscle preservation.
• Chronic kidney disease (conservative management): Supplies essential amino acids while limiting nitrogen load.
• Severe burns: Assists in meeting heightened protein requirements for healing.
• Long‑term parenteral nutrition: Provides a balanced amino acid profile for patients unable to use the gastrointestinal tract.

• The formulation delivers a balanced blend of essential and non‑essential amino acids that are directly incorporated into protein synthesis pathways. By supplying substrates for ribosomal translation, it facilitates tissue repair, enzyme production, and metabolic functions while helping to maintain plasma amino acid concentrations and nitrogen balance.

Amino acid mixtures are generally well tolerated, but adverse reactions can occur.

Common Side Effects

• Nausea: mild to moderate gastrointestinal discomfort.
• Vomiting: occasional episodes, especially if administered rapidly.
• Diarrhea: loose stools in some patients.
• Abdominal cramping: transient discomfort after ingestion.
• Metallic taste: perception of a metallic flavor in the mouth.
• Headache: mild headache reported by some users.

Serious or Rare Side Effects

• Hyperammonemia: elevated blood ammonia levels, particularly in severe liver dysfunction.
• Allergic reaction: rash, itching, or urticaria.
• Anaphylaxis: rare, severe systemic hypersensitivity.
• Metabolic acidosis: rare disturbance of acid‑base balance.
• Electrolyte imbalance: abnormal serum potassium or calcium levels.
• Renal impairment worsening: potential increase in serum creatinine in susceptible patients.

When using Olimel Perifer N4e, consider the following safety measures:

• Renal function: assess baseline kidney parameters before initiating therapy.
• Hepatic function: monitor liver enzymes in patients with known liver disease.
• Electrolyte status: check serum electrolytes regularly during prolonged use.
• Nutritional assessment: ensure the product fits within the overall dietary plan.
• Concomitant nutrition: avoid excessive protein intake from other sources.
• Store at ambient temperature: keep in the original container, protect from moisture and direct sunlight.

Amino acid mixtures can interact with certain medications and nutrients.

Major Interactions (Avoid)

• Levodopa: may reduce absorption of levodopa, diminishing its effectiveness.
• MAO inhibitors: risk of hypertensive crisis when combined with high‑tyrosine content.
• Thyroid hormone replacement: can interfere with absorption of levothyroxine.

Moderate Interactions (Monitor Closely)

• Anticonvulsants (e.g., phenytoin): may alter plasma amino acid levels.
• Diuretics: can affect electrolyte balance when combined with high‑sodium formulations.
• Iron supplements: compete for intestinal absorption sites, reducing iron uptake.
