EVALOSE vs PROMETHAZINE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Promethazine is a phenothiazine derivative that acts as a potent histamine H1 receptor antagonist, thereby blocking the effects of histamine. It also has central anticholinergic, antiemetic, and sedative properties, likely mediated through antagonism at muscarinic, dopamine D2, and serotonin receptors in the brain.
Adults: 1-2 tablets (5-10 mg) orally once daily, adjusted to maximum 20 mg/day.
12.5-25 mg IM or IV every 4-6 hours; also 25 mg PO or PR every 6-8 hours. Maximum 100 mg/day.

Clinical Note
moderatePromethazine + Risedronic acid
"Promethazine can cause an increase in the absorption of Risedronic acid resulting in an increased serum concentration and potentially a worsening of adverse effects."
Clinical Note
moderatePromethazine + Methylphenidate
"Promethazine can cause an increase in the absorption of Methylphenidate resulting in an increased serum concentration and potentially a worsening of adverse effects."
Clinical Note
moderatePromethazine + Artesunate
"The serum concentration of Artesunate can be increased when it is combined with Promethazine."
Clinical Note
moderateTerminal 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
Terminal elimination half-life 9-16 hours; may be prolonged in hepatic impairment.
Renal: 70% unchanged; Biliary/Fecal: 20% as metabolites; 10% other
Renal (70-80% as metabolites, <1% unchanged); biliary/fecal minor.

Antihistamine / Antiemetic
Promethazine + Clotrimazole
"The metabolism of Clotrimazole can be decreased when combined with Promethazine."
