India gets low cost biosimilar of Remicade

[Caroline]

A question regarding biosimilars are their any restrictions on where they can be sold?
What I mean is are we likely to see price wars or pressure on the other drugs to reduce prices?

My understanding is that they can only be sold in the country they are approved for, they have to go through the same tests as the original to be deemed suitable under that countries regulations.

So in India both will be available but Infimab will be offered as a cheaper alternative, but as it's not approved for use say in the UK then it will still be Remicade that UK residents will get.

Yes that is correct.
E.g. Tecfidera is released in the Netherlands for MS. So now there is an obligation to use this only for MS. While cheaper variants are available.
Which is the same why Infimab will not be used in the UK, but instead Remicade is provided.
There is no reason for the industry to change that, as Remicade brings them more money, it is as easy as that.
