Torbugesic and acepromazine may be combined and administered in the same syringe. However the vials should have separate needles inserted for withdrawal to minimise the risk of cross contamination.
Allow at least 20 minutes for onset of action but the time between premedication and induction is flexible from 20-120 minutes.
The dose of butorphanol may be increased to 0.2 mg/kg (equivalent to 0.2 ml Torbugesic Injection/10 kg bodyweight) if the animal is already experiencing pain before the procedure commences, or if a higher plane of analgesia is required during surgery.

Domitor and Torbugesic may be combined and administered in the same syringe. However, the vials should have separate needles inserted for withdrawal to minimise the risk of cross-contamination.
Dogs become recumbent in approximately 6 minutes and lose their pedal reflex in approximately 14 minutes.
Ketamine (100 mg/ml) should be administered 15 minutes following the first injection at 0.5 ml/10 kg (equivalent to 5 mg ketamine/kg) by intramuscular injection.
The pedal reflex returns approximately 53 minutes following administration of the ketamine injection. Sternal recumbency is attained approximately 35 minutes later followed by standing a further 36 minutes later.

CAT
For pre-operative analgesia
0.2 ml Torbugesic injection/ 5 kg bodyweight (equivalent to 0.4 mg butorphanol/kg), should be administered either by subcutaneous or intramuscular injection. Clinical studies have shown that administering the butorphanol dose 5 minutes prior to induction with either acepromazine/ketamine or xylazine/ketamine given intramuscularly will provide analgesia when surgery commences. The arousal time will not be significantly altered. With intravenous induction agents, butorphanol should be administered 15–30 minutes prior to administration of the anaesthetic.
For post-operative analgesia
0.2 ml Torbugesic Injection/ 5 kg bodyweight (equivalent to 0.4 mg butorphanol/kg), should be administered by either subcutaneous or intramuscular injection 15 minutes prior to recovery. Alternatively, 0.05 ml Torbugesic Injection/5 kg (equivalent to 0.1 mg butorphanol/kg), by intravenous injection can be used.
