Usage
This combination is prescribed primarily to decrease mucus secretion in individuals with lung diseases like bronchitis, asthma, and emphysema. It also addresses nutritional deficiencies. Its pharmacological classifications include mucolytic agent and nutritional supplement.
Acetylcysteine works by breaking down disulfide bonds in mucus, reducing its viscosity. Arginine and lysine provide nutritional support, while L-histidine, a precursor to histamine, may offer immunomodulatory and antioxidant benefits.
Alternate Names
Aminodrip Infusion (brand name)
How It Works
Pharmacodynamics: Acetylcysteine exerts its mucolytic effect by disrupting disulfide bonds in mucoproteins, decreasing viscosity. Arginine and Lysine are essential amino acids involved in protein synthesis and various metabolic processes. L-Histidine is a precursor to histamine, involved in immune regulation and gastric acid secretion.
Pharmacokinetics: Acetylcysteine is rapidly absorbed after oral administration. It’s metabolized in the liver and excreted primarily in the urine. Arginine, Lysine, and L-Histidine are absorbed in the small intestine and participate in regular amino acid metabolic pathways. Elimination pathways are primarily renal.
Dosage
Standard Dosage
Adults:
500 mL infused intravenously over 120 minutes. A maximum daily dosage of 2500 mL has been reported.
Children:
Safety and efficacy in children have not been established. Dosage adjustments, if deemed necessary by a physician, would be based on the child’s weight and clinical condition.
Special Cases:
- Elderly Patients: A reduced infusion rate is advised.
- Patients with Renal Impairment: Dose modification is essential.
- Patients with Hepatic Dysfunction: Caution and potential dose adjustment may be necessary.
- Patients with Comorbid Conditions: Requires consideration, especially for congestive heart failure or electrolyte imbalances.
Clinical Use Cases
Dosage in clinical settings like intubation, surgical procedures, mechanical ventilation, ICU use, or emergency situations is determined by the specific situation and patient condition. Consult a physician for specific recommendations.
Dosage Adjustments
Adjustments are needed based on renal or hepatic function, age, and other patient-specific factors.
Side Effects
Common Side Effects
Injection site reactions, allergic reactions, bronchospasm.
Rare but Serious Side Effects
Severe allergic reactions (anaphylaxis).
Long-Term Effects
Not well established.
Adverse Drug Reactions (ADR)
Severe allergic reactions requiring immediate medical intervention.
Contraindications
Severe hepatic or renal impairment, congestive heart failure, severe acidosis, electrolyte abnormalities.
Drug Interactions
Acetylcysteine may interact with activated charcoal, antibiotics (azithromycin, chloramphenicol, clarithromycin, etc.), and various other medications. Arginine may interact with antihypertensive medications, nitrates, and sildenafil. L-Histidine and Lysine interactions are less documented but may interfere with certain mineral absorption. Always check for potential interactions with other medications a patient may be taking, including OTC drugs and supplements. Food and lifestyle factors (e.g., alcohol, smoking) should also be considered.
Pregnancy and Breastfeeding
Use during pregnancy or breastfeeding should be avoided unless benefits outweigh risks, as safety has not been established in these populations.
Drug Profile Summary

Popular Combinations
Combinations with other respiratory medications (e.g., bronchodilators, corticosteroids) may be used in clinical practice based on the patient’s specific respiratory condition.
Precautions
Pre-screening for allergies, metabolic disorders, organ dysfunction is necessary. Specific precautions are needed for pregnant or breastfeeding women, children, elderly patients, and those with comorbid conditions. Lifestyle considerations such as alcohol consumption and smoking should be assessed.
FAQs (Frequently Asked Questions)
