Selank Pharmacokinetics
Selank half-life, absorption, routes of administration, and clearance.
Tuftsin-Derived Stability: The Pro-Gly-Pro Pharmacokinetic Advantage
Selank's pharmacokinetics center on the Pro-Gly-Pro tripeptide extension that transforms unstable tuftsin (half-life: minutes) into a clinically viable intranasal drug with sustained CNS activity.
