Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cladribine is a prodrug that is phosphorylated intracellularly to its active triphosphate form, which inhibits DNA synthesis and repair, leading to lymphocyte depletion. It selectively targets and reduces circulating T and B lymphocytes, thereby modulating the immune response in multiple sclerosis.
Purine nucleoside analog that inhibits DNA synthesis and repair by incorporating into DNA and inhibiting ribonucleotide reductase and DNA polymerases.
3.5 mg/kg body weight administered orally as two treatment courses of 1.75 mg/kg each over two consecutive weeks (cumulative dose 3.5 mg/kg per year). Each course is given as a 14-day period: 1.75 mg/kg in divided doses daily for 4 or 5 days, depending on patient preference (e.g., 10 mg tablets daily for that period).
5 mg/m2 intravenously over 20-30 minutes every 3 weeks.

Terminal elimination half-life of cladribine is approximately 5.7 days (range 4-10 days) following oral administration. This long half-life supports once-daily high-dose short-course dosing and is due to slow release from lymphocytes. Clinical context: Allows sustained intracellular levels of active triphosphate in lymphocytes.
Terminal elimination half-life is approximately 5-8 hours in patients with normal renal function. Clinically, the half-life may be prolonged in renal impairment, requiring dose adjustments.
Approximately 100% of cladribine dose is eliminated via renal excretion of unchanged drug and metabolites, with <5% recovered in feces. Renal clearance is about 2/3 of total clearance. Biliary elimination is negligible.
Primarily renal excretion; approximately 50-70% of the dose is excreted unchanged in urine within 24 hours. Minor biliary/fecal elimination accounts for <5%.
