Sedation in Ball Pythons
Reptile · Python regius · typical adult weight 1.00–2.00 kg
10 cited drugs treat Sedation in ball pythons: Acepromazine, Alfaxalone, Atropine, Butorphanol, Butorphanol Injectable, Dexmedetomidine, Ketamine, Medetomidine, Metomidate, Midazolam.
Pharmacologic sedation for diagnostic procedures, minor surgical interventions, and pre-anaesthetic premedi-cation. α2 agonists (dexmedetomidine, medetomidine), phenothiazines (acepromazine), and benzodiazepines (midazolam) form the backbone of veterinary protocols.
The overview above describes Sedation across species; the citations below are the ExoticRx dose rules scoped to ball pythons — a reference list, not new species-specific clinical guidance.
