Analgesic and antipyretic agent.

Paracetamol, Para-aminophenol derivative is a peripherally acting analgesic and is
well absorbed orally. Paracetamol produces analgesia by elevation of the pain
threshold and antipyresis through action on hypothalamic heat regulating center.

Oral Paracetamol is rapidly and almost completely absorbed from the gastrointestinal
tract primarily in the small intestine, with negligible absorption occuring in the stomach.
The relative bioavailability ranges from 85% to 98%. Each tablet contains 300 mg
immediate release in one layer and 700 mg sustained release designed to release
slowly in another layer. The in vitro data indicates that the tablet releases 90% of the drug
within 8 hours. From the in vivo data it is concluded that the average maximum plasma
concentration occurs within 0.5 to 2 hours following ingestion and range from 6.86
ug/mL to 10.37 ug/mL among individuals. Paracetamol appears to be widely distributed
throughout most body fluids except fat and small proportions bound to plasma proteins.
Paracetamol is primarily metabolized in the liver. The elimination half-life of
Paracetamol in healthy adults is approximately 2 to 3 hours in the usual dosage range
The mean elimination half-life is 4.84 hours.

It is indicated for the treatment of fever, acute pain and chronic pain.

Known hypersensitivity to Paracetamol or ingredient in the formula.

Dermatologic: Rash
Endocrine & metabolic: May increase chloride, uric acid, glucose; may decrease
sodium, bicarbonate, calcium.

Hematologic: Anemia, blood dyscrasias (neutropenia, pancytopenia, leukopenia)
Heptic: Bilirubin increased; alkaline phosphatase increased.
Renal: Ammonia increased, nephrotoxicity with chronic overdose, analgesic nephropathy.

Paracetamol should be administered with caution to patients with hepatic or renal
dysfunctions. Adults who are using warfarin should consult with a doctor or pharmacist
before taking Paracetamol. Not recommended for children under 12 years of age.
Adults should take Paracetamol 1g for pain for more than 10 days or for fever for

recommended dose of Paracetamol may cause liver damage. Following suspected
overdosage, evaluate necessity of antidote therapy.

The absorption of Paracetamol may be altered by Metoclopramide & Anticholinergic
Agents (e.g. Propantheline, Glycopyrolate and Exanatide). The metabolism of
Paracetamol may be altered by Alcohol, Isoniazid, Ascorbic Acid, Ciprofloxacin,
Diflunisal, Rifampicin, Omeprazole, Chloramphenicol, Oral Contraceptives,
Probenecid, Propranolol, Sulfinpyrazone, Zidovudine, Lamotrigine. Paracetamol is

Use in Elderly Patients
In cases of elderly patients who may have decreased liver and renal functions, peak plasma concentration of the drug is increased and clearance of loratadine is altered. Thus, lower dose of its drug should be given to them (See Dosage and Administration).

Use in Children
Once a day dose of loratadine has been proven effective and safe in children 3 to 12 years of age for the treatment of allergic rhinitis. The safety of loratadine in patients younger than 2 years old is not yet  established (See Dosage and Administration).

Use in Pregnant Women

(Animal reproduction studies have failed to demonstrate a risk to the fetus and there are no adequate and well-controlled studies in pregnant women OR Animal studies which have shown an adverse effect, but adequate and well controlled studies in pregnant women have failed to demonstrate a risk to the fetus in any trimester.) Use of loratadine in pregnant women is not associated with a large risk for major malformations. Administrations of loratadine during pregnancy may only be recommended if the potential benefit justifies the risk to the fetus.

Use in Lactating Mothers
