Sinapol Oral Suspension

Paracetamol acts primarily in the central nervous system (CNS) to relieve pain and reduce fever. It increases the pain threshold by inhibiting prostaglandin synthesis and acts on the hypothalamic heat-regulating center to produce antipyresis.

Unlike NSAIDs, it has minimal peripheral anti-inflammatory action. Its exact mechanism involves inhibition of COX enzymes (including COX-1, COX-2, and possibly COX-3), which reduces prostaglandin production. This results in analgesic and antipyretic effects without significant gastrointestinal irritation or platelet inhibition.

Dosage & Administration

Dosage varies by formulation and age:

• Adults: 1–2 tablets every 4–6 hours; maximum 4 g/day (8 tablets)
• Children (6–12 years): ½–1 tablet 3–4 times daily
• Syrup (Children): Dose varies by age and weight, 3–4 times daily
• Suppository: Used in children and adults based on age and weight
• IV form: Dose adjusted by body weight and clinical condition

Do not exceed the recommended daily dose.

Drug Interactions

• Alcohol and enzyme-inducing drugs (barbiturates, anticonvulsants, tricyclic antidepressants) may increase liver toxicity risk or reduce effectiveness.
• Chronic use of certain medications (e.g., anticonvulsants, oral contraceptives) may increase metabolism of paracetamol, lowering its therapeutic effect.

Contraindications

Sinapol should not be used in patients with:

• Known hypersensitivity to paracetamol

Side Effects

Generally well tolerated. Rare but possible adverse effects include:

• Skin rash and allergic reactions
• Blood disorders (thrombocytopenia, leukopenia, neutropenia, agranulocytosis)
• Pancreatitis (rare)

Use in Pregnancy & Lactation

Paracetamol is generally considered safe during pregnancy when used at recommended doses. It passes into breast milk in small amounts but is not known to cause harmful effects in infants. Use only under medical guidance.

Precautions & Warnings

• Do not exceed recommended dose (risk of severe liver damage)
• Use with caution in liver or kidney impairment
• Avoid in chronic alcoholism and malnutrition
• Do not combine with other paracetamol-containing products
• Overdose may cause serious hepatotoxicity and may be fatal
• Caution in patients with dehydration, severe illness, or low body weight

Use in Special Populations

• Children: Safe when properly dosed by weight/age
• Elderly: Generally safe; monitor liver/kidney function if needed
• Renal impairment: Dose adjustment may be required
• Hepatic impairment: Use cautiously; reduced dose recommended

Overdose Information

Overdose may cause severe liver injury, which can be life-threatening. Early symptoms include nausea, vomiting, abdominal pain, and loss of appetite. Severe cases may progress to liver failure, kidney damage, metabolic acidosis, or death.

Immediate medical treatment is required. Activated charcoal may be used if taken recently, and N-acetylcysteine is the specific antidote.

Therapeutic Class

Non-opioid analgesic and antipyretic
