ALYQ vs TYZAVAN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
ALYQ (alectinib) is a selective and potent anaplastic lymphoma kinase (ALK) inhibitor. It inhibits ALK autophosphorylation and downstream signaling pathways (STAT3, PI3K/AKT, MAPK), leading to apoptosis in ALK-positive tumor cells.
Levodopa is converted to dopamine in the brain, replenishing depleted dopamine levels in the striatum, improving motor function. Carbidopa inhibits peripheral decarboxylation of levodopa, increasing its central availability.
Intravenous: 400 mg on Day 1, then 200 mg daily for 4 days; total 5 doses per cycle.
200 mg orally once daily, taken with food.

Terminal elimination half-life is approximately 6-8 hours in adults with normal renal function; prolonged in renal impairment.
Terminal elimination half-life is 12–15 hours in patients with normal renal function; prolonged to 30–50 hours in severe renal impairment (CrCl <30 mL/min).
Primarily renal excretion as unchanged drug (approximately 70-80%) and biliary/fecal elimination (20-30%) following intravenous administration.
Renal excretion (70–80% unchanged); biliary/fecal excretion accounts for 15–20% as metabolites.
