IMIPRAMINE HYDROCHLORIDE vs PRESAMINE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Tricyclic antidepressant that inhibits the reuptake of norepinephrine and serotonin at presynaptic neuronal membranes, increasing their synaptic concentrations. Also has anticholinergic, antihistaminergic, and alpha-1 adrenergic blocking effects.
Predominantly inhibits serotonin reuptake in the presynaptic neuron, increasing serotonin availability in the synaptic cleft. Also inhibits norepinephrine reuptake to a lesser extent.
Initial 75 mg/day orally in divided doses, increase to 150-200 mg/day; maximum 300 mg/day. For maintenance, 50-150 mg/day orally.
100-300 mg/day orally in divided doses, typically starting at 75 mg/day and titrating upward. Maximum dose 300 mg/day.
