1. Clinical Overview
A fixed-dose combination (FDC) of proteolytic enzymes (Trypsin and Bromelain), a bioflavonoid (Rutoside), and a non-steroidal anti-inflammatory drug (NSAID - Diclofenac). This combination is primarily used in India for the management of acute inflammatory conditions, post-operative/traumatic edema, and pain. The enzymes and rutoside are believed to enhance the anti-inflammatory and anti-edema effects of diclofenac, potentially allowing for lower NSAID doses and improved tissue permeability.
| Onset | Duration | Bioavailability |
|---|---|---|
| Diclofenac: Analgesic effect within 30-60 minutes; Anti-inflammatory effect may take up to 7 days. Enzymes/Rutoside: Effects on edema and inflammation are typically observed within 2-3 days of regular dosing. | Diclofenac: 8-12 hours (for immediate-release formulations). The enzyme components have a sustained effect on tissue healing and inflammation modulation. | Diclofenac: ~50-60% (oral). Trypsin (enteric-coated): Minimal systemic absorption, acts locally in GI tract and absorbed fragments may have systemic effects. Bromelain: Low and variable oral bioavailability (~10-40%). Rutoside: Poorly absorbed (<20%), metabolized by gut flora to active metabolites. |
2. Mechanism of Action
Diclofenac provides primary analgesic and anti-inflammatory action via non-selective inhibition of cyclooxygenase (COX-1 and COX-2), reducing prostaglandin synthesis. Trypsin and Bromelain are proteolytic enzymes that may reduce edema by breaking down inflammatory mediators (bradykinin, fibrin), improving microcirculation, and facilitating tissue drainage. Rutoside (a flavonoid) is thought to reduce capillary fragility and permeability through antioxidant activity and inhibition of hyaluronidase, potentially stabilizing capillary walls and reducing swelling. The combination aims for a multi-targeted approach to inflammation, pain, and edema.
3. Indications & Uses
- Acute musculoskeletal disorders (sprains, strains, low back pain)
- Post-operative inflammation and edema (e.g., dental surgery, orthopedic procedures)
- Traumatic swelling and pain (e.g., fractures, soft tissue injuries)
- Osteoarthritis flare-ups with associated inflammation and pain
4. Dosage & Administration
Adult Dosage: One tablet three times daily (TDS) after meals. The total daily dose of diclofenac is 150mg. Duration should not exceed 7-10 days without re-evaluation.
Administration: Take with or immediately after food with a full glass of water to minimize gastrointestinal irritation. Do not crush, chew, or break the enteric-coated tablet. Swallow whole.
5. Side Effects
Common side effects may include:
- Dyspepsia, heartburn, epigastric pain
- Nausea
- Diarrhea or loose stools (enzymes can cause this)
- Headache, dizziness
- Skin rash, pruritus
6. Drug Interactions
| Drug | Effect | Severity |
|---|---|---|
| Anticoagulants (Warfarin, Acenocoumarol) | Increased risk of bleeding due to antiplatelet effect of diclofenac and possible enzyme effects. | Major |
| Anti-platelets (Aspirin, Clopidogrel) | Increased GI bleeding risk. | Major |
| Other NSAIDs (including COX-2 inhibitors) | Increased risk of GI and renal toxicity; no therapeutic advantage. | Major |
| ACE Inhibitors (Ramipril, Enalapril) / ARBs (Losartan) | Reduced antihypertensive effect; increased risk of renal impairment. | Moderate |
| Diuretics (Furosemide, Hydrochlorothiazide) | Reduced diuretic efficacy; risk of renal failure. | Moderate |
| Lithium | Increased serum lithium levels and toxicity. | Major |
| Methotrexate | Increased methotrexate toxicity (especially with high dose). | Major |
| Corticosteroids (Prednisolone) | Markedly increased risk of GI ulceration. | Major |
| Antibiotics (Quinolones e.g., Ciprofloxacin) | Increased risk of CNS stimulation/seizures. | Moderate |
| Cyclosporine, Tacrolimus | Increased nephrotoxicity. | Major |
7. Patient Counselling
- DO take with food and a full glass of water.
- DO swallow the tablet whole; do not crush or chew.
- DO inform your doctor about all other medicines you are taking, including OTC drugs and supplements.
- DO report any signs of black/tarry stools, vomiting blood, or severe stomach pain immediately.
- DONT take if you are pregnant (especially last trimester) or planning pregnancy without consulting your doctor.
- DONT exceed the prescribed dose or duration.
- DONT take other painkillers (like ibuprofen, aspirin) along with this unless advised.
- DONT consume alcohol while on this medication.
8. Toxicology & Storage
Overdose: Primarily diclofenac toxicity: Nausea, vomiting, epigastric pain, GI bleeding, headache, dizziness, drowsiness, tinnitus, hyperventilation, convulsions, acute renal failure, liver damage, respiratory depression, coma.
Storage: Store below 30°C in a cool, dry place, protected from light and moisture. Keep out of reach of children.
