CHILDREN'S ELIXSURE vs NAPROXEN SODIUM
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Acetaminophen: weakly inhibits cyclooxygenase (COX) in central nervous system, reduces prostaglandin synthesis, elevates pain threshold, and acts on hypothalamic heat-regulating center to lower body temperature. Chlorpheniramine: first-generation antihistamine; competitively antagonizes histamine at H1 receptors, reducing allergic symptoms. Dextromethorphan: noncompetitive NMDA receptor antagonist and sigma-1 agonist; suppresses cough by elevating threshold in medullary cough center. Pseudoephedrine: indirectly acting sympathomimetic; releases norepinephrine from presynaptic terminals, causing vasoconstriction and nasal decongestion.
Non-selective cyclooxygenase (COX-1 and COX-2) inhibitor, reducing prostaglandin synthesis.

Terminal half-life: 4–6 hours in children with normal hepatic function; prolonged to >8 hours in hepatic impairment or overdose.
12–17 hours (terminal); allows twice-daily dosing; prolonged in elderly and renal impairment
Renal elimination: ~90% as unchanged drug and active metabolite paracetamol glucuronide/sulfate conjugates; biliary/fecal: <5%.
Renal: 95% (as unchanged drug, conjugated naproxen, and 6-O-desmethyl naproxen); Fecal: <5%
