• Pharmacokinetics profiles of C. purpureomaculatus venom in rabbits were investigated
• The serum levels of the venom were estimated using double-sandwich ELISA
• The serum concentration–time course fitted a two-compartment model
• T1/2β, clearance and Vd of the venom via i.m. route were comparable to the i.v. route
• The intramuscular bioavailability of the venom was estimated to be 41.6%.
The pharmacokinetic profiles of Cryptelytrops purpureomaculatus (mangrove pit viper) venom following intravenous and intramuscular injections were investigated in rabbits. The serum levels of the venom were estimated using double-sandwich enzyme-linked immunosorbent assay (ELISA). After intravenous injection (0.2 mg/kg), the serum venom concentration–time course declined in a biexponential manner, consistent with a two-compartment model, with an α-phase half-life of 0.25 h and a β-phase half-life of 27.7 h. The volume of distribution by area was 2.19 L/kg and systemic clearance was 54.7 mL/h/kg. When the venom was injected intramuscularly (0.5 mg/kg), the serum level increased rapidly to reach a peak (500 ng/mL) at about 1 h, which then declined rapidly to a plateau (104–142 ng/mL) at 3–10 h before further gradual decline until the end of the 72-hour study. The terminal half-life (27.0 h), clearance (54.7 mL/h/kg) and volume of distribution (2.13 L/kg) of the venom for intramuscular route were not significantly different from the corresponding values for intravenous route, and the intramuscular bioavailability of the venom was estimated to be 41.6%.
