Patient w/ CHF, uncontrolled HTN, ischaemic heart disease, peripheral arterial disease, cerebrovascular disease and those w/ risk factors for CV disease (e.g. HTN, hyperlipidaemia, DM, smoking); bronchial asthma, history of GI disease (e.g. ulcerative colitis, Crohn’s disease). Renal or hepatic impairment. Pregnancy and lactation.

Oedema, HTN, cardiac failure, nausea, epigastric pain, diarrhoea, indigestion, heartburn, flatulence, abdominal pain, constipation, vomiting, ulcerative stomatitis, dyspepsia, haematemesis, melaena, rectal bleeding, exacerbation of colitis, vasculitis, headaches, dizziness, abnormal vision, pyrexia, drowsiness, tinnitus, rash, pruritus, fatigue, depression, insomnia, confusion, paraesthesia, tremor, weakness, dyspnoea, palpitations, bilirubinuria, hepatic function abnormalities, jaundice, urinary frequency, Crohn’s disease, photosensitivity, asthma, nephritis, anaemia.
Potentially Fatal: Serious CV thrombotic events (e.g. stroke, MI), GI effects (e.g. perforation, bleeding and ulceration), fulminant hepatitis, liver necrosis, hepatic failure. Very rarely, serious skin reactions (e.g. Stevens-Johnson syndrome, toxic epidermal necrolysis, exfoliative dermatitis).

PO: C, Z (NSAIDs caused foetal ductus arteriosus premature closure, foetal renal impairment and persistent pulmonary hypertension. Avoid near term, else use lowest dose for shortest time.)

This drug may cause dizziness, drowsiness, fatigue or abnormal vision, if affected, do not drive or operate machinery.

Monitor for signs and symptoms of GI bleeding and hepatic dysfunction; renal function, BP at the beginning of therapy and periodically; CBC and chemistry profile (long-term therapy).

Symptoms: Lethargy, drowsiness, nausea, vomiting, epigastric pain, GI bleeding, coma, HTN, acute renal failure, resp depression. Management: Symptomatic and supportive treatment. Perform emesis and/or administer activated charcoal or osmotic cathartic w/in 4 hr of ingestion.

May increase the effect of lithium, warfarin and methotrexate. Increased risk of adverse effect w/ aspirin or other NSAIDs. May reduce the effect of diuretics, mifepristone and antihypertensives. Increased risk of nephrotoxicity w/ ciclosporin, diuretics and tacrolimus, Increased risk of GI bleeding w/ SSRIs, anti-platelets and corticosteroids. Increased risk of convulsions w/ quinolone antibiotics. Increased risk of haematological toxicity when given w/ zidovudine. May exacerbate cardiac failure, reduce GFR and increase serum level w/ of cardiac glycoside.

May decrease GI upset and serum peak levels when taken w/ food. Alcohol enhances gastric mucosal irritation.

False-positive reaction for urinary bilirubin and ketones.

Description:
Mechanism of Action: Etodolac is an NSAID derived from pyrano-indoleacetic acid which inhibits cyclooxygenase 2 (COX-2), resulting in decreased prostaglandin precursor formation.
Onset: Analgesia: Approx 30 min (conventional preparation). Arthritis (chronic use): W/in 2 wk.
Duration: Mean range: 4-6 hr.
Pharmacokinetics:
Absorption: Rapidly absorbed. Bioavailability: ≥80%. Time to peak plasma concentration: W/in approx 2 hr.
Distribution: Distributed to synovial fluid. Volume of distribution: Approx 390 mL/kg. Plasma protein binding: >99%, primarily to albumin.
Metabolism: Extensively metabolised in the liver to hydroxylated metabolites and etodolac glucuronide; hydroxylated metabolites undergo further glucuronidation.
Excretion: Mainly via urine (73%); faeces (16%).
