DIPHENHYDRAMINE HYDROCHLORIDE PRESERVATIVE FREE vs EVALOSE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Competitive antagonist of histamine H1 receptors; centrally acting anticholinergic agent that inhibits acetylcholine muscarinic receptors.
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.
25 to 50 mg intravenously or intramuscularly every 4 to 6 hours as needed; maximum 400 mg per day.
Adults: 1-2 tablets (5-10 mg) orally once daily, adjusted to maximum 20 mg/day.

Terminal elimination half-life: 4-10 hours (mean ~8 hours); prolonged in hepatic impairment or elderly (up to 20 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 as inactive metabolites; ~60% of a dose appears in urine as metabolites, with <5% unchanged. Minor biliary/fecal elimination (<10%).
Renal: 70% unchanged; Biliary/Fecal: 20% as metabolites; 10% other
