Common Immobilizing Drugs

| Drug Class | Examples | Key Features | Notes |

|--------------|------------|----------------|--------|

| Alpha-2 Agonists | Medetomidine, Xylazine | Sedation, muscle relaxation | Reversible with atipamezole or yohimbine |

| Dissociatives | Ketamine, Tiletamine | Analgesia, anesthesia | Often combined with sedatives for balanced immobilization |

| Opioids | Morphine, Butorphanol | Analgesia | Used in combination with other agents |

| Sedatives/Tranquilizers | Acepromazine, Diazepam | Sedation | Usually adjuncts |

Species-Specific Protocols for Wildlife Immobilization

Different species require tailored approaches considering their physiology, behavior, and habitat. Proper protocol selection minimizes risks and enhances success.

Mammals
