Precautions

Use at lowest effective dose for shortest duration possible. NSAIDs may increase risk of severe cardiovascular (CV) thrombotic events, myocardial infarction, and stroke. Risk may be increased with duration of use or pre-existing CV disease or risk factors. Treatment has been associated with new onset hypertension or worsening of pre-existing hypertension. May cause fluid retention and oedema; caution in heart failure. NSAIDs can cause serious GI adverse events including GI inflammation, ulceration, bleeding, and perforation. Caution in patients with history of GI disease; concomitant use of aspirin, anticoagulants and/or oral corticosteroids; smoking, use of alcohol, elderly or debilitated patients. Anaemia may occur, monitor CBC in patients who are on long term NSAIDs. May inhibit platelet aggregation and prolong bleeding in some patients. Rare cases of sever hepatotoxicity including jaundice, fatal fulminant hepatitis, liver necrosis and hepatic failure have been reported. May cause renal impairment; patients with pre-existing renal impairment, heart failure, liver dysfunction, concomitant use of diuretics and ACE inhibitors, volume-depleted and elderly are at greater risk. Use is not recommended in advance renal impairment. Caution in patients with pre-existing asthma; avoid in patients with history of aspirin-sensitive asthma. May cause serious skin reactions including exfoliative dermatitis, Steven-Johnson syndrome and toxic epidermal necrolysis. Aseptic meningitis in patients with SLE; pancreatitis have been reported. Pharmacokinetics has not been studied in paediatric patients. Should not be used during 3rd trimester of pregnancy. Lactation. Lactation: not known if distributed in milk

Pregnancy-Lactation

Pregnancy Category: B; D if used for prolonged periods, or near term (may cause premature closure of ductus arteriosus) Lactation: not known if distributed in milk

Interactions

Concomittent use with dimethyl sulfoxide may result in peripheral neuropathy. Increased nephrotoxicity with ciclosporin; increased risk of methotrexate toxicity; increased risk of bleeding with other NSAIDs, warfarin and thrombolytic agents.

Mechanism of Action

Sulindac is a prodrug which undergoes reversible reduction to its active sulfide metabolites. It inhibits prostaglandin synthesis by decreasing cyclooxygenase activity.
