No, this is the name of a Non-steroidal anti-inflammatory drug - a painkiller that is used here in the UK safely in rabbits. If you read the article re. pain relief and analgesia in rabbits it will give you a list of rabbit-safe pain relief. I'm sure your vet knows about these - you could always print out and show him the article?
And I forgot to ask one more question – my doctor told me that when molar teeth were too long it meant the teeth changed in the root of teeth and nobody could change it . - -- is it true?
Yes to some extent this is true. As molar teeth don't wear properly it is believed that the incorrect mechanical wear of the surface of the tooth can lead to tooth root overgrowth - and vice versa. The article I sent you by David Crossley explains how 'burring' the molar teeth correctly down to the gum line in 'some cases' (and this must be done under a general anaesthetic and pain relief must be given for many days after the operation minimum) can sometimes 'improve' tooth root elongation. It will not necessarily correct it unfortunately no.
The most important things for your rabbit are
pain relief and a diet high in abrasive fibre - hay/grass.
For general anaesthetics - there are newer techniques used here in the UK recently. I don't know if you have these in Russia - but it would be worth asking your vet about it and whether or not he can do some research into safe rabbit anaesthetics if he is unsure.
Can you get hold of some fresh herbs freshly grown such as basil, coriander, thyme, mint, parsley? Rabbits love these and the strong smell can really help encourage a poorly bunny to eat.
Does your vet stock any Critical Care type formula like this? or anything similar for small animals?

This preparation is very high in fibre and can be helpful if a bun is too ill to eat themselves as it is a mixture you can feed by syringe.
There are also some recipes here: Or you can mush up rabbit pellets with some warm water and see if he will eat these either himself or by a syringe.

It is important to keep him hydrated whilst he is not eating properly so if you feed him some leaves or veggies try offering them washed and still wet to get some extra fluids into him. I expect he is losing a lot of fluid from drooling. You may need to ask your vet to give him fluids under the skin - subcutaneously. If he has any sores in his mouth he will possibly need some more antibiotics to prevent infection.
Can you get hold of some herbal tea bags? Peppermint tea? Camomile tea? if you make a cup and let it cool you can offer him this or by syringe - buns like the taste and it will help keep his fluid levels up in his body. :wave:
