Usage
- L-Ornithine L-Aspartate + Silymarin is prescribed for managing various liver diseases. These include hepatic encephalopathy, acute and chronic hepatitis, chronic alcoholic liver damage, fatty liver disease (both alcoholic and non-alcoholic), jaundice, liver cirrhosis, and non-alcoholic steatohepatitis (NASH). It may also be used as supportive treatment for toxic liver injury and adjunctive therapy during antiviral treatment for viral hepatitis.
- Pharmacological Classification: Hepatoprotective, detoxifying agent.
- Mechanism of Action: This combination leverages the synergistic effects of L-Ornithine L-Aspartate and Silymarin. L-Ornithine L-Aspartate reduces ammonia levels via the urea cycle, converting toxic ammonia to urea for renal excretion. This improves liver function and mitigates hepatic encephalopathy symptoms. It also promotes liver cell regeneration by boosting protein synthesis and energy production. Silymarin acts as an antioxidant and anti-inflammatory agent, shielding liver cells from free radical damage, reducing inflammation, stabilizing cell membranes, and stimulating new liver cell growth.
Alternate Names
- L-Ornithine L-Aspartate and Silymarin combination
- Silymarin and L-Ornithine L-Aspartate
How It Works
- Pharmacodynamics: L-Ornithine L-Aspartate participates in the urea cycle, reducing ammonia levels, a key factor in hepatic encephalopathy. Silymarin exerts antioxidant and anti-inflammatory effects, stabilizing liver cell membranes and stimulating regeneration.
- Pharmacokinetics: Information on the absorption, distribution, metabolism, and excretion of this specific drug combination is not readily available in the provided sources. However, it is generally taken orally and assumed to be metabolized by the liver.
- Mode of Action: L-Ornithine L-Aspartate enhances the urea cycle, detoxifying ammonia. Silymarin acts as an antioxidant, protecting liver cells from damage.
- Receptor Binding, Enzyme Inhibition, or Neurotransmitter Modulation: The sources do not mention any specific receptor binding, enzyme inhibition, or neurotransmitter modulation associated with this combined medicine.
- Elimination Pathways: The provided materials do not explicitly describe the elimination pathways, but renal excretion likely plays a crucial role due to the urea cycle involvement in L-Ornithine L-Aspartate’s mechanism of action.
Dosage
Standard Dosage
Adults:
- The usual adult dosage is 500-1000mg of L-Ornithine L-Aspartate combined with 140-200mg of Silymarin, taken orally two to three times a day.
- Dosage and treatment duration should be tailored to the patient’s specific condition and requirements, as determined by a physician.
Children:
- The safety and effectiveness of this medication for children under 12 have not been established. Use in pediatric patients is generally not recommended. If deemed necessary, a healthcare professional should determine and closely monitor dosage based on the child’s weight and condition.
Special Cases:
- Elderly Patients: Dosage adjustments may be necessary for elderly patients due to age-related metabolic changes and potential organ function decline.
- Patients with Renal Impairment: Dosage modification may be needed depending on the degree of impairment. Caution is recommended in patients with severe kidney issues.
- Patients with Hepatic Dysfunction: Dosage modification should be considered in cases of hepatic dysfunction to avoid exacerbation of liver problems.
- Patients with Comorbid Conditions: Consider existing conditions, like diabetes or cardiovascular disease, as they might influence drug metabolism or increase risks.
Clinical Use Cases
The provided sources do not offer specific dosage recommendations for clinical settings such as intubation, surgical procedures, mechanical ventilation, ICU use, or emergency situations. Dosage decisions in these contexts require expert medical judgment based on the patient’s overall condition, organ function, and concomitant therapies.
Dosage Adjustments
Dose adjustments are patient-specific and consider factors such as renal/hepatic dysfunction, metabolic disorders, or genetic polymorphisms that can affect drug metabolism.
Side Effects
Common Side Effects
- Headache
- Tiredness
- Nausea
- Mild gastrointestinal disturbances (diarrhea, abdominal pain, flatulence, bloating)
- Pruritus (itching)
Rare but Serious Side Effects
- Allergic skin reactions
- Pain in the limbs
- Vomiting
- Skin irritation
- Drowsiness
Long-Term Effects
The provided texts do not detail specific long-term effects. However, long-term use could theoretically affect kidney function due to urea excretion, so periodic monitoring of kidney health might be advised. Excessive and prolonged use could potentially contribute to dental issues like caries.
Adverse Drug Reactions (ADR)
While not explicitly mentioned in the sources as ADRs, severe allergic reactions, significant gastrointestinal distress (e.g., persistent vomiting, severe diarrhea), or worsening of pre-existing conditions could be considered as such and necessitate medical intervention.
Contraindications
- Hypersensitivity to L-Ornithine L-Aspartate or Silymarin.
- Severe renal impairment.
- Hormone-sensitive conditions (e.g., breast cancer, uterine cancer, endometriosis, uterine fibroids) should be considered with caution due to Silymarin’s potential estrogenic effects.
Drug Interactions
- Levodopa (antiparkinson drug) - may reduce the effectiveness of L-Ornithine L-Aspartate + Silymarin.
- Alcohol - increases the risk of liver damage.
- Antidiabetic agents (e.g., metformin, glipizide)
- Sedatives (e.g., diazepam, lorazepam)
- Opioids (e.g., morphine, fentanyl)
- Antidepressants (e.g., fluoxetine, citalopram, sertraline)
- Immunosuppressants (e.g., sirolimus, tacrolimus)

Pregnancy and Breastfeeding
- Consult a doctor before use during pregnancy or breastfeeding.
- Caution is advised due to potential risks, though specific pregnancy safety categories or detailed data on fetal risks are not available in the provided sources. Silymarin’s potential estrogenic effects are a concern during pregnancy.
