Usage
- Etodolac + Tolperisone is prescribed for the management of acute musculoskeletal pain conditions, especially those accompanied by muscle spasms. This includes conditions like osteoarthritis with muscle spasms, low back pain, and other similar conditions involving pain, inflammation, and muscle stiffness.
- Pharmacological Classification: Nonsteroidal anti-inflammatory drug (NSAID) + Centrally acting muscle relaxant.
- Mechanism of Action: Etodolac inhibits cyclooxygenase (COX) enzymes, reducing prostaglandin synthesis, thereby decreasing pain and inflammation. Tolperisone acts centrally, likely at the spinal cord and brainstem, to reduce muscle spasms and improve mobility.
Alternate Names
- No widely recognized alternate generic names exist.
- Brand Names: Etogesic T, various others depending on the region and manufacturer.
How It Works
- Pharmacodynamics: Etodolac exerts its anti-inflammatory and analgesic effects by inhibiting COX-1 and COX-2 enzymes, thus reducing prostaglandin production. Tolperisone’s muscle relaxant properties are thought to stem from its action on the central nervous system, though the precise mechanism isn’t fully elucidated. It likely modulates neuronal activity in the spinal cord and brainstem, leading to reduced muscle tone and spasm.
- Pharmacokinetics: Etodolac is well-absorbed orally, with high bioavailability. It’s extensively metabolized in the liver and primarily excreted by the kidneys. Tolperisone’s pharmacokinetic profile isn’t as well-defined, but it is also metabolized in the liver and excreted by the kidneys.
- Mode of Action: Etodolac inhibits COX enzymes. Tolperisone’s precise molecular mechanism is not fully understood, but it likely involves modulation of neurotransmitter systems involved in muscle control.
- Elimination Pathways: Both Etodolac and Tolperisone are primarily eliminated through hepatic metabolism and renal excretion.
Dosage
Standard Dosage
Adults:
- The typical dose is one tablet of Etodolac 400 mg + Tolperisone 150 mg twice daily. Dosage may be adjusted based on individual patient response and tolerability.
Children:
- Not generally recommended for patients under 18 years of age. Safety and efficacy have not been established in pediatric populations.
Special Cases:
- Elderly Patients: Initiate therapy at the lower end of the dosing range and monitor for side effects. Careful dose titration is recommended due to potential age-related decline in renal and hepatic function.
- Patients with Renal Impairment: Exercise caution. Dose adjustment may be necessary in patients with severe renal dysfunction.
- Patients with Hepatic Dysfunction: Exercise caution. Dose adjustment may be necessary in patients with severe hepatic impairment.
- Patients with Comorbid Conditions: Use cautiously in patients with cardiovascular disease, hypertension, or a history of peptic ulcers. Monitor closely for any adverse events.
Clinical Use Cases
- This combination isn’t typically used in settings requiring intubation, surgical procedures, mechanical ventilation, ICU care, or emergency situations. Its primary indication is for managing musculoskeletal pain with muscle spasms in an outpatient setting.
Dosage Adjustments
- Dose adjustments are based on patient-specific factors like renal and hepatic function. Always consider comorbidities and concomitant medications when determining the appropriate dose.
Side Effects
Common Side Effects:
- Nausea, vomiting, indigestion, diarrhea, abdominal pain, dizziness, drowsiness, headache, weakness.
Rare but Serious Side Effects:
- Gastrointestinal bleeding, peptic ulcers, allergic reactions, cardiovascular events (e.g., heart attack, stroke), kidney damage, liver dysfunction, skin reactions.
Long-Term Effects:
- Potential for gastrointestinal complications, renal damage, and cardiovascular events with prolonged use.
Adverse Drug Reactions (ADR):
- Any signs of allergic reaction, severe gastrointestinal symptoms, cardiovascular events, or significant changes in renal/hepatic function should prompt immediate medical attention.
Contraindications
- Hypersensitivity to Etodolac, Tolperisone, or other NSAIDs.
- History of asthma, urticaria, or allergic-type reactions after aspirin or other NSAID use.
- Active gastrointestinal bleeding or peptic ulcer disease.
- Perioperative pain associated with coronary artery bypass graft (CABG) surgery.
- Myasthenia gravis.
Drug Interactions
- Other NSAIDs, anticoagulants (e.g., warfarin), muscle relaxants (e.g., baclofen), anticholinergic agents, antihypertensives, digoxin, lithium, quinolone antibiotics, cyclosporine, mifepristone, alcohol.
Pregnancy and Breastfeeding
- Not recommended during pregnancy and breastfeeding unless the potential benefits outweigh the risks. Safety hasn’t been adequately established.
Drug Profile Summary

FAQs (Frequently Asked Questions)
Q1: What is the recommended dosage for Etodolac + Tolperisone?
A: The typical adult dose is 400 mg Etodolac + 150 mg Tolperisone twice daily.
Q2: How does this combination work to manage pain and muscle spasm?
A: Etodolac reduces pain and inflammation by inhibiting COX enzymes, while Tolperisone reduces muscle spasms through its central action.
Q3: Is this combination safe for patients with a history of stomach ulcers?
A: No, it’s contraindicated in patients with active or a history of gastrointestinal bleeding or peptic ulcer disease.
Q4: Can this drug be taken with other pain medications?
A: Combining it with other NSAIDs should be avoided due to increased risk of side effects. Consult a doctor before combining with any other pain medications.
Q5: Can patients operate machinery or drive while taking this medication?
A: Use caution as dizziness and drowsiness are potential side effects. Avoid these activities if such side effects occur.
Q6: Are there any specific dietary restrictions while on this medicine?
A: No specific dietary restrictions exist, but maintaining a healthy diet is always recommended.
