Torcoxia P

Uses

Etoricoxib is used for relief of pain and inflammation in-

• Osteoarthritis

• Following dental surgery

Torcoxia P is also used to associated treatment for these conditions: Ankylosing Spondylitis (AS), Gouty Arthritis, Osteoarthritis (OA), Rheumatoid Arthritis, Moderate Pain

How Torcoxia P works

Like any other COX-2 selective inhibitor Etoricoxib selectively inhibits isoform 2 of cyclo-oxigenase enzyme (COX-2), preventing production of prostaglandins (PGs) from arachidonic acid.

Dosage

Torcoxia P dosage

The recommended dose for adult and patient over 16 years:

• Acute pain: 120 mg once daily. Etoricoxib 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 Etoricoxib.

Elimination Route

Bioavailability is 100% following oral administration.
