Indications & Uses

Pharmacology

Sulindac is a non-steroidal anti-inflammatory drug that relieves pain, reduces inflammation, and brings down fever, likely by blocking prostaglandin synthetase, the mechanism thought to underlie NSAIDs generally. Once absorbed, sulindac is first oxidised to a sulphone and then reversibly reduced to a sulphide, and it is this sulphide form that is biologically active, working by inhibiting prostaglandin synthesis.

Cautions & Contraindications

Warnings & Precautions

Sulinzen should be used with caution in patients with impaired kidney function, bleeding disorders, epilepsy, parkinsonism or psychiatric disorders. In patients with liver impairment, the half-life of Sulinzen is prolonged and a reduction in the daily dose may be needed. Anaemia is sometimes seen in patients receiving NSAIDs together with Sulinzen.

Contraindications

Sulindac should not be used by people who are allergic to it, or by those who have had an acute asthma attack, hives (urticaria) or a runny nose (rhinitis) triggered by aspirin or other non-steroidal anti-inflammatory drugs. It is also not suitable for people with a history of active gastrointestinal bleeding or peptic ulcers. Sulindac should not be given to children, or to women who are pregnant or breastfeeding.

Pregnancy & Breastfeeding

Pregnancy: During the first two trimesters, Sulindac should be used only if the potential benefit justifies the potential risk to the foetus. It is not recommended during the third trimester.

Breastfeeding: It is not known whether Sulindac passes into human milk. The decision to stop breastfeeding or stop the medicine should be made after weighing how important the medicine is to the mother.

⚠️ Talk to your doctor before taking any medicine during pregnancy or while breastfeeding.

Use in Special Populations

Patients with renal impairment: Sulin should be given with caution to people whose kidney function is impaired. The same care applies to those with bleeding disorders, epilepsy, parkinsonism or psychiatric disorders.

Patients with hepatic impairment: When liver function is impaired, the half life of Sulin is prolonged, so a lower daily dose may be needed.

Overdose

Symptoms reported after an overdose of Sulin have mostly pointed to toxicity in the gastro-intestinal tract, the kidneys and the central nervous system. Treatment is symptomatic and supportive.
