Tương tác
May enhance the effect of anticoagulants (e.g. warfarin).

Increased absorption by domperidone and metoclopramide Decreased absorption by cholestyramine and other drugs that reduce gastric emptying time (e.g. narcotic analgesics, propantheline, antidepressants with anticholinergic properties). Altered plasma concentration with probenecid. Concomitant use with zidovudine, co-trimoxazole or isoniazid (alone or with other anti-TB drugs) may result in severe hepatotoxicity.

May increase the plasma levels of cardiac glycosides. May increase the risk of nephrotoxicity when given with ciclosporin and tacrolimus. May decrease the elimination of lithium and methotrexate. May increase the risk of convulsions associated with quinolone antibiotics. Increased risk of haematological toxicity with zidovudine.
Potentially Fatal: Concomitant use with paracetamol- or NSAID-containing drugs (e.g. COX-2 inhibitors, aspirin) may result in serious adverse effects.

Tác dụng
Description: Ibuprofen, an NSAID, has analgesic, anti-inflammatory and antipyretic properties. It inhibits cyclooxygenase-1 and 2 (COX-1 and -2) enzymes, thereby also inhibiting prostaglandin synthesis.
Paracetamol is a para-aminophenol derivative with analgesic and antipyretic properties and weak anti-inflammatory activity. The mechanisms by which paracetamol exhibits its analgesic and antipyretic effects are not yet fully elucidated. Its analgesic effect may include inhibition of central prostaglandin synthesis and modulation of inhibitory descending serotonergic pathways while its antipyretic property may be due to reduced production of prostaglandin in the hypothalamus. It has a weak anti-inflammatory activity.
Absorption: Ibuprofen: Well absorbed from the gastrointestinal tract. Time to peak plasma concentration: Approx 1-2 hours.
Paracetamol: Readily absorbed from the gastrointestinal tract. Time to peak plasma concentration: Approx 10-60 minutes.
Distribution: Ibuprofen: Plasma protein binding: 90-99%. Enters breast milk (small amounts).
Paracetamol: Distributed into most body tissues. Crosses the placenta, enters breast milk.
Metabolism: Ibuprofen: Extensively metabolised in the liver into inactive compounds mainly via glucuronidation.
Paracetamol: Extensively metabolised in the liver. N-acetyl-p-benzoquinoneimine (NAPQI), a minor metabolite produced by CYP2E1 and CYP3A4 in the liver and kidney, is further metabolised via conjugation with glutathione.
Excretion: Ibuprofen: Mainly via urine (approx 1% as unchanged drug, approx 14% as conjugates). Elimination half-life: Approx 2 hours.
Paracetamol: Via urine (mainly as inactive glucuronide and sulfate conjugates; <5% as unchanged drug). Elimination half-life: Approx 1-3 hours.
