Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Purine nucleoside analog that inhibits DNA synthesis and repair by incorporating into DNA and inhibiting ribonucleotide reductase and DNA polymerases.
Uvadex, when combined with UVA light, intercalates into DNA and upon UVA activation forms covalent cross-links with pyrimidine bases, thereby inhibiting DNA synthesis and inducing apoptosis in activated T-cells.
5 mg/m2 intravenously over 20-30 minutes every 3 weeks.
200 mcg/mL solution administered via intravenous injection 0.017 mL/kg (3.4 mcg/kg) 30 minutes prior to each photopheresis treatment, given on two consecutive days every 2–4 weeks.

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.
Terminal elimination half-life is approximately 12 hours (range 8-20 hours) following intravenous administration; clinically, this supports daily dosing schedules.
Primarily renal excretion; approximately 50-70% of the dose is excreted unchanged in urine within 24 hours. Minor biliary/fecal elimination accounts for <5%.
Primarily renal excretion of unchanged drug (approximately 70% within 24 hours) and metabolites; minor fecal elimination (<10%).
