AZELASTINE HYDROCHLORIDE CHILDREN'S ALLERGY vs EVALOSE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Azelastine hydrochloride is a phthalazinone derivative that acts as a selective histamine H1-receptor antagonist. It inhibits the release of histamine and other mediators from mast cells, reduces chemotaxis, and decreases eosinophil activation. It also suppresses leukotriene and cytokine production.
EVALOSE is a selective serotonin reuptake inhibitor (SSRI) that potentiates serotonergic activity by blocking the reuptake of serotonin at the presynaptic neuron, thereby increasing serotonin levels in the synaptic cleft.
Azelastine hydrochloride nasal spray: 1 spray (137 mcg) per nostril twice daily; maximum 2 sprays per nostril twice daily.
Adults: 1-2 tablets (5-10 mg) orally once daily, adjusted to maximum 20 mg/day.

Terminal elimination half-life is 22–25 hours in adults; steady state achieved in 3–5 days. In children (6–11 years), half-life is similar (mean 22 hours).
Terminal elimination half-life is 12 hours (range 10-14 h); clinically significant for once-daily dosing in most patients with normal renal function; extend dosing interval in renal impairment
Primarily renal (approximately 75%), with about 50% as unchanged drug and 25% as metabolites via CYP3A4 and CYP2D6. Fecal excretion accounts for ~20%.
Renal: 70% unchanged; Biliary/Fecal: 20% as metabolites; 10% other
