Panadol Extend is a sustained release formulation of paracetamol that provides gentle and long-lasting relief from back and pain and even for persistent joint pain (such as osteoarthritis) for up to 8 hours. It can also be taken by people who have other conditions such as stomach ulcers and high blood pressure. The patented bi-layer caplet starts to release one layer straight away for fast pain relief, while the second layer is released slowly over a period to give long-lasting relief. This means longer lasting back and pain relief than ordinary Panadol, with the improved convenience of fewer doses. And you can rest assured it won’t harm your stomach.
