Professor R.O. Day and Professor G.G. Graham, authors of 'The vascular effects of COX-2 selective inhibitors', comment:
The idea of a sustained release paracetamol is very reasonable. The reduction in the number of daily doses would make long-term therapy with paracetamol more convenient. The problem is that the dose is large and the optimal sustained release tablet, say one that would last for 12 or even 24 hours, would be very large and too difficult to swallow. Cost-effectiveness would also need to be established for it to be subsidised by the PBS.
