1. Clinical Overview
A fixed-dose combination product containing L-Ornithine L-Aspartate (LOLA), an ammonia-lowering agent, and Pancreatin, a digestive enzyme supplement. It is primarily used in the management of hepatic encephalopathy (HE) and associated digestive insufficiency in patients with chronic liver disease. LOLA works by enhancing the urea cycle and glutamine synthesis in the liver and skeletal muscle, facilitating ammonia detoxification. Pancreatin compensates for exocrine pancreatic insufficiency, aiding in the digestion of fats, proteins, and carbohydrates, which is often compromised in chronic liver disease patients.
| Onset | Duration | Bioavailability |
|---|---|---|
| L-Ornithine L-Aspartate: Reduction in blood ammonia levels can be observed within 1-2 hours. Pancreatin: Digestive action begins within 30-60 minutes of ingestion with a meal. | L-Ornithine L-Aspartate: Clinical effects on mental status in HE may last 8-12 hours, requiring multiple daily doses. Pancreatin: Effects are localized to the gastrointestinal tract and last for the duration of digestion. | L-Ornithine L-Aspartate: Ornithine and aspartate are absorbed via the gastrointestinal tract. Bioavailability data is limited but absorption is considered good. Pancreatin: Enzymes are not systemically absorbed; they act locally in the intestinal lumen. |
2. Mechanism of Action
L-Ornithine L-Aspartate (LOLA): Provides substrates (ornithine and aspartate) for two key ammonia-detoxifying pathways. 1) Urea Cycle: Ornithine is a direct intermediate, enhancing the conversion of ammonia to urea in periportal hepatocytes. 2) Glutamine Synthesis: In perivenous hepatocytes and skeletal muscle, glutamate (derived from aspartate) combines with ammonia to form glutamine, a non-toxic storage and transport form. Pancreatin: Contains lipase, amylase, and protease enzymes derived from porcine pancreas. It compensates for deficient endogenous pancreatic secretion, facilitating the hydrolysis of dietary triglycerides into fatty acids and monoglycerides, starches into dextrins and sugars, and proteins into peptides and amino acids.
3. Indications & Uses
- Adjunctive therapy in the management of overt and minimal Hepatic Encephalopathy (HE) in patients with cirrhosis
- Management of digestive insufficiency (dyspepsia, bloating, steatorrhea) associated with chronic liver disease and exocrine pancreatic insufficiency
4. Dosage & Administration
Adult Dosage: Typically 1-2 tablets, three times daily. For HE: Often 2 tablets thrice daily with meals. For digestive issues: 1-2 tablets with each main meal. The exact dose should be individualized based on severity.
Administration: Tablets should be swallowed whole with a glass of water, preferably during or immediately after meals. Do NOT crush or chew the tablets, as this may destroy the enteric coating of Pancreatin, leading to inactivation by gastric acid and potential oral mucosal irritation. Maintain adequate hydration.
5. Side Effects
Common side effects may include:
- Nausea
- Abdominal discomfort or pain
- Flatulence
- Diarrhea or loose stools
- Vomiting
6. Drug Interactions
| Drug | Effect | Severity |
|---|---|---|
| Lactulose | Additive/synergistic ammonia-lowering effect. Beneficial interaction. | Moderate |
| Rifaximin | Additive/synergistic ammonia-lowering effect. Beneficial interaction. | Moderate |
| Allopurinol | Theoretical interaction due to effects on purine metabolism; monitor uric acid. | Minor |
| Antacids (especially H2 blockers, PPIs like Omeprazole) | May increase gastric pH, potentially causing premature release of Pancreatin enzymes in the stomach, reducing efficacy. Separate administration by 1-2 hours. | Moderate |
| Iron supplements | Pancreatin may impair iron absorption. Administer at different times of the day. | Moderate |
| Folic acid supplements | Pancreatin may impair folate absorption. Administer at different times. | Moderate |
7. Patient Counselling
- DO take the tablet during or immediately after meals.
- DO swallow the tablet whole with plenty of water. Do NOT crush, break, or chew.
- DO inform your doctor if you have kidney problems or gout.
- DO continue your other prescribed medications for liver disease (e.g., lactulose).
- DONT consume alcohol while on this medication.
- DONT take antacids at the same time. Separate by at least 1-2 hours.
8. Toxicology & Storage
Overdose: LOLA: Nausea, vomiting, diarrhea, gastrointestinal cramps. In severe renal impairment, could lead to hyperammonemia. Pancreatin: High doses may cause nausea, abdominal cramps, diarrhea, and rarely, hyperuricosuria or fibrosing colonopathy (with extreme, chronic overdose).
Storage: Store below 25°C, in a cool, dry place. Protect from moisture and direct sunlight. Keep the container tightly closed. Keep out of reach of children. Do not use after the expiry date printed on the pack.
