Etrobax
Etrobax Uses, Dosage, Side Effects, Food Interaction and all others data.
Etrobax is a non-steroidal anti-inflammatory drug (NSAID) that exhibits anti-inflammatory, analgesic, and antipyretic activities. Etrobax is a potent, orally active & highly selective cyclooxygenase-2 (COX-2) inhibitor. COX-2 is primarily responsible for the synthesis of prostanoid mediators of pain, inflammation and fever. Etrobax decreases these clinical signs and symptoms effectively with decreased GI toxicity. Moreover it has no effect on platelet function.
Etrobax is a COX-2 selective inhibitor (approximately 106 times more selective for COX-2 inhibition over COX-1).

Uses
Etrobax is used for relief of pain and inflammation in-
- Osteoarthritis
- Rheumatoid arthritis
- Other chronic musculoskeletal disorders
- Acute gout
- Dysmenorrhoea
- Following dental surgery
Etrobax is also used to associated treatment for these conditions: Ankylosing Spondylitis (AS), Gouty Arthritis, Osteoarthritis (OA), Rheumatoid Arthritis, Moderate Pain
How Etrobax works
Like any other COX-2 selective inhibitor Etrobax selectively inhibits isoform 2 of cyclo-oxigenase enzyme (COX-2), preventing production of prostaglandins (PGs) from arachidonic acid.
Dosage
Etrobax dosage
The recommended dose for adult and patient over 16 years:
- Acute pain: 120 mg once daily. Etrobax 120 mg should be used only for acute symptomatic period, limited to a maximum of 8 days treatment.
- Chronic musculoskeletal pain: 60 mg once daily.
- Osteoarthritis: 30 mg once daily, increased if necessary to 60 mg once daily.
- Rheumatoid arthritis and ankylosing spondylitis: 90 mg once daily.
- Acute gout: 120 mg once daily for max. 8 days. Max. 60 mg daily in mild hepatic impairment; max. 60 mg on alternate days or 30 mg once daily in moderate hepatic impairment.
Side Effects
Dry mouth, taste disturbance, mouth ulcer, flatulence, constipation, appetite and weight changes, chest pain , fatigue, paraesthesia, influenza like syndrome, myalgia etc. may occur.
Toxicity
This reduced activity is the cause of reduced gastrointestinal toxicity, as demonstrated in several large clinical trials performed with different COXIB (see below links on NEJM and The Lancet). Some clinical trials and meta-analysis showed that treatment with COXIB lead to increased incidence of cardiovascular adverse events compared to placebo
Precaution
A patient with decreased liver & kidney function, dehydration, hypertension, heart failure, GI perforation & patients over 65 years of age. Use in Pregnancy and Lactation As with other drugs known to inhibit prostaglandin synthesis, use of it should be avoided in late pregnancy because it may cause premature closure of the ductus arteriosus. It should be used during the first two trimesters of pregnancy only if the potential benefit justifies the potential risk to the foetus. It is not known whether this drug is excreted in human milk.
Interaction
Oral anticoagulants, diuretics and ACE inhibitors, Acetylsalicylic acid, Cyclosporin and Tacrolimus, Lithium, Methotrexate, oral contraceptives, Prednisone/Prednisolone, Digoxin, drugs metabolized by sulfotransferases (Ethinyl Estradiol), drugs metabolized by CYP isoenzymes, Ketoconazole, Rifampicin, and Antacids have interaction with Etrobax.
Food Interaction
- Take with or without food. The absorption is unaffected by food.
Elimination Route
Bioavailability is 100% following oral administration.
Half Life
22 hours
Pregnancy & Breastfeeding use
As with other drugs known to inhibit prostaglandin synthesis, use of it should be avoided in late pregnancy because it may cause premature closure of the ductus arteriosus. It should be used during the first two trimesters of pregnancy only ifthe potential benefit justifies the potential risk to the foetus. It is not known whether this drug is excreted in human milk.

FAQ
What is the use of Etrobax?
Etrobax helps to reduce the pain and swelling (inflammation) in the joints and muscles of people 16 years of age and older with osteoarthritis, rheumatoid arthritis, ankylosing spondylitis and gout. Etrobax is also used for the short term treatment of moderate pain after dental surgery in people 16 years of age and older.
What is Etrobax?
Etrobax (Etoricoxib) is a selective inhibitor of cyclooxygenase-2 (COX-2), an enzyme involved in pain and inflammation. It is a member of the COX-2-selective (coxib) class of nonsteroidal antiinflammatory drugs (NSAIDs). Extensive clinical trials have confirmed its analgesic and antiinflammatory efficacy to be at least as good as and in some cases superior to nonselective NSAIDs in a number of disease and patient treatment settings. Etrobax displays improved gastrointestinal safety compared with nonselective NSAIDs and has a favorable overall safety and tolerability profile. It is rapidly and completely absorbed following oral administration providing a rapid onset of action. Its long plasma half-life allows for once-daily dosing. Etrobax is currently approved in a number of countries for various indications including the treatment of acute pain, acute gouty arthritis, chronic low back pain, primary dysmenorrhea, and chronic treatment for the signs and symptoms of osteoarthritis and rheumatoid arthritis.
Is Etrobax a strong painkiller?
Etrobax eases pain and swelling (inflammation) in conditions like osteoarthritis, rheumatoid arthritis and ankylosing spondylitis, and it may also be used for short periods of time in gout. Etrobax works by blocking the effect of a natural chemical called cyclo-oxygenase-2 (COX-2) enzyme.
What are the side effects of Etrobax?
The most common side effects of Etrobax are stomach ache, indigestion, wind, feeling sick, diarrhoea, constipation, headache, feeling tired or dizzy, wheezing, palpitations and increased blood pressure.
How long does Etrobax take to work?
The onset of pain relief was rapid, with similar benefit reported within 4 hours of the first dose of Etrobax.
What is the best time to take Etrobax?
Taking Etrobax at the same time each day will have the best effect. It will also help you remember when to take the dose. It does not matter if you take Etrobax before or after food.
Can I take Etrobax for toothache?
The 120 mg dose of Etrobax was reported to be as effective as, or better than other commonly used analgesics. Studies on Etrobax in the dental extraction pain model have proved the superior efficacy of Etrobax with fewer adverse effects as compared to oxycodone/acetaminophen.
How many days can I take Etrobax?
Etrobax should be used only for the acute symptomatic period, limited to a maximum of 8 days treatment. Doses greater than those recommended for each indication have either not demonstrated additional efficacy or have not been studied. Therefore: The dose for OA should not exceed 60 mg daily.
How many Etrobax can I take a day?
Osteoarthritis: The recommended Etrobax dose is 30 mg or 60 mg once daily.
Rheumatoid Arthritis: The recommended Etrobax dose is 60 mg or 90 mg once daily. The minimum effective daily dose is 60 mg once daily. In some patients, 90 mg once daily may provide increased therapeutic benefit.
Is Etrobax safe for elderly?
Etrobax is generally well tolerated in clinical trials of patients with OA and other types of arthritis. We observed an improvement of the quality of life in the extremely elderly patients, with the given treatment dose and period that was shorter compared to the other trials.
Can I cut Etrobax in half?
Do not halve tablet. Studies on divided tablets have not been performed.
Is Etrobax a sulfa drug?
Etrobax is a methylsulfone and does not contain the sulfonamide moiety that has been associated with an increased risk of hypersensitivity reactions.
Is Etrobax safe during pregnancy?
The potential for human risk in pregnancy is unknown. Etrobax, as with other medicinal products inhibiting prostaglandin synthesis, may cause uterine inertia and premature closure of the ductus arteriosus during the last trimester. Etrobax is contraindicated in pregnancy.
Is Etrobax safe during breastfeeding?
Etrobax is excreted in the milk of lactating rats. Women who use Etrobax must not breast feed. The use of Etrobax, as with any drug substance known to inhibit COX-2, is not recommended in women attempting to conceive.
