Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Testosterone replacement therapy; binds to androgen receptors, promoting protein synthesis, muscle growth, and secondary sexual characteristic development.
Mirtazapine is a tetracyclic antidepressant that acts as a potent antagonist of central α2-adrenergic autoreceptors and heteroreceptors, leading to increased norepinephrine and serotonin neurotransmission. It also antagonizes 5-HT2 and 5-HT3 receptors, with no significant effect on serotonin reuptake.
Intramuscular injection: 50-100 mg every 2-4 weeks.
10-15 mg orally every 6 hours as needed for agitation in dementia; maximum 60 mg/day.
