No idea if this also applies in the UK but the start of cheaper GCA medication is here! And European - it is a Swiss company.
The patent for tocilizumab ran out recently - and this is the first drug to take advantage of that. A biosimilar is a biologic medical product that is almost an identical copy of an original product that is manufactured by a different company. Biosimilars are officially approved versions of original "innovator" products and can be manufactured when the original product's patent expires.
Hopefully this may make it more available.
