So potentially a very long list!
Basically I’d break them down into NSAIDS (that give both pain relief and anti-inflammatory action) and other pain killers that can be used alongside them.
Mom itself a list of NSAIDs is long. Most are used once a day. The main ones would be:
metacam/meloxaid/loxicom (same drug)
onsior
rimadyl
previcox
carprieve
trocoxil (given once a month)
Then you’ve got drugs that can be alongside these (as we would advise all dog with OA be on an NSAID unless there is a specific reason why not.
These could include:
gabapentin
tramadol
pardale (paracetamol)
amantadine
There are a host of injectable drugs too which might be used as a one off or as part of a regular programe at the vets:
Cartrophen
ketamine
vetergesic
methadone
…
some supplements are thought to perhaps have analgesic properties too and of course things like laser therapy and acupuncture work to relieve pain.
