Roche had exclusive rights called a ‘patent’ on pirfenidone. Until now, only Roche could manufacture and distribute pirfenidone in the UK.
Now that Roche’s patent has expired, other manufacturers can market generic versions of pirfenidone. The generic versions will be the same as the branded medicine Esbriet® because they contain the same active ingredients.
There are no generic alternatives to Esbriet® currently available in the UK, but it’s likely there will be over the coming months. Generic drugs are often used by the NHS because they're just as effective but cost less.
· Currently only pirfenidone that is manufactured by Roche, called Esbriet®, is available in the UK.
· Any patient who is starting pirfenidone will receive this medication.
· If you are already receiving pirfenidone(Esbriet®), you will continue to receive this medication.
· There will be no changes to your current medication or its method of delivery.
· When generic medications become available in the UK, this may result in pirfenidone being supplied by a different pharmaceutical manufacturer. Your hospital team who prescribe pirfenidone will keep you informed of any changes to your medication.
