Buprenorphine Rodent Analgesia

  1.  Short Acting Buprenorphine HCL

 

  1. Dosage and Dosing Interval: 

 

Buprenorphine HCL (Buprenex™)

Dosage

Interval

Mouse

0.1 mg/kg SQ

every 4 hours

Rat

0.01-0.05 mg/kg SQ

every 4 hours

 

  1. How to purchase: E-mail eileen_goodwin@urmc.rochester.edu (SMH Pharmacy Vault Specialist Technician) to place an order for a 3ml vial (~$375) with a 28-day shelf life once opened. A 3 ml vial will dose ~20 rats or ~60 mice.  You must have a DEA controlled substance cabinet approved by Pharmacy and a UCAR approved protocol describing the use of buprenorphine.

 

  1. Extended Release (XR) Buprenorphine (Ethiqa™)

 

  1. Dosage and Dosing Interval:

 

Buprenorphine XR (Ethiqa™)

Dosage

Interval

Mouse

3.25 mg/kg SQ

every 48-72 hours

Rat

0.65 mg/kg SQ

every 48-72 hours

 

  1. How to purchase: An email account has been set up to submit narcotic orders to that will be monitored by a few people to ensure that orders are filled and billed.

    It is  ARLControlledSubstanceOrders@URMC.Rochester.edu

    Please include the following on your PO’s:

  • Number of vials requested, even if it is just one
  • An email address to send any questions they may have to
  • The lab name (the PI’s name, not just neurology for example)
  • Account number to be billed
  • If ordering Ketamine, please specify if you want the 5 ml vial or the 10 ml vial  (for reference, 5 ml vial is 100mg/ml and 10ml is 50mg/ml)
  • Two signatures
  • UCAR number

Pick up orders at the pharmacy located in the basement just off the green elevators.

  1. Sustained Release (SR) Buprenorphine 

 

  1. Dosage and Dosing Interval:

 

Buprenorphine SR (ZooPharm™)

Dosage

Interval

Mouse

0.5-1.0 mg/kg SQ

every 48-72 hours

Rat

1.0-1.2 mg/kg SQ

every 48-72 hours

 

  1. How to purchase: Electronically submit this REDCap form  3-days in advance to the Animal Resource Office for a vial providing up to 7-day supply of Buprenorphine SR before it expires.  See this link for charges.

 

  1. Tips for Subcutaneous Administration:   Use a single-use insulin syringe for each dose (provided with BUP-SR when ordered from Animal Resource-DCM). Be aware that the long acting suspensions are oil-based and take patience to draw up. Mouse SQ Injection handout.

 

  1. Specific Risk Factor for Respiratory Depression:  First time users of buprenorphine occasionally observe respiratory depression intra-operatively in mice or rats.  Respiratory depression poses no challenge when using inhalation isoflurane given gas anesthesia’s wide margin of safety and ease of adjustment.  However, if using injectable anesthetics (e.g. ketamine-xylazine), be aware that you “may” need to reduce the xylazine component of the anesthetic dose or wait several hours after pre-emptive administration before performing surgery to avoid intra-operative respiratory depression. 

 

The Animal Resource provides isoflurane anesthetic vaporizers free of charge for your use in most rodent procedure rooms. Research staff need to purchase their own bottle of isoflurane to use this equipment. Isoflurane vaporizers are also available to rent for a daily fee in research labs outside of the vivarium.To purchase isoflurane, submit your order through the Animal Resource Website.

 

  1. Post-Operative Monitoring Documentation:  Please be certain to fully complete and insert a green post-op card, per usual practice, in each cage card holder. Even though the long acting buprenorphine affords 48 to 72 hours of analgesia, research staff must document daily observations on the green post-op cage card and 24-hours beyond the 72 hour analgesic therapeutic range to confirm a pain-free, post-operative mouse off analgesics.
