PROMAZINE HYDROCHLORIDE vs TINDAL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Promazine hydrochloride is a phenothiazine antipsychotic that blocks postsynaptic dopamine D2 receptors in the mesolimbic system, as well as histamine H1, alpha-1 adrenergic, and muscarinic cholinergic receptors. It also has moderate serotonin and weak serotonin-dopamine antagonist effects.
TINDAL (trimethoprim) inhibits bacterial dihydrofolate reductase (DHFR), preventing the reduction of dihydrofolate to tetrahydrofolate, thereby inhibiting bacterial DNA synthesis.
25-50 mg intramuscularly every 4-6 hours as needed. Maximum 150 mg/day.
TINDAL (ticarcillin disodium + clavulanate potassium) 3.1 g (ticarcillin 3 g + clavulanic acid 0.1 g) IV every 4-6 hours. Maximum dose: 18 g ticarcillin/0.6 g clavulanic acid per day.

Terminal elimination half-life: 12-18 hours; in elderly or hepatic impairment may extend to 30 hours
Terminal elimination half-life is approximately 12-15 hours in adults with normal renal function; prolonged in renal impairment.
Primarily renal (approx. 70-80% as metabolites, <1% unchanged); minor biliary/fecal (approx. 15-20%)
Primarily renal excretion of unchanged drug (70-80%) and hepatic metabolism (20-30%).
