ADREVIEW vs THYROGEN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
ADREVIEW is a beta-2 adrenergic receptor agonist that stimulates cyclic AMP production, leading to bronchodilation and inhibition of mast cell mediator release.
Recombinant human thyroid-stimulating hormone (TSH) that binds to TSH receptors on thyroid follicular cells, stimulating iodine uptake, thyroglobulin synthesis, and release of thyroid hormones.
0.5 mg intramuscularly every 20 minutes as needed, up to 3 doses, for acute allergic reactions; or 0.1-0.5 mg subcutaneously for bronchospasm.
0.9 mg intramuscular injection every 24 hours for 2 doses, or 1.2 mg orally as a single dose.

Terminal elimination half-life is 2-3 hours; clinically relevant for dosing every 4-6 hours in renal impairment.
12-15 hours (terminal elimination half-life in patients with normal renal function; may be prolonged in renal impairment). Clinically, TSH levels peak by 3 hours after IM injection and return to baseline by 24-48 hours.
Primarily renal (80-90% as unchanged drug), with minor biliary/fecal elimination (<10%).
Primarily renal (thyrotropin is a glycoprotein hormone; intact hormone is minimally excreted unchanged; metabolic degradation products are eliminated renally). After IV administration, approximately 96% of the dose is recovered in urine within 24 hours as low molecular weight degradation products. Biliary/fecal excretion is negligible (<1%).
