A dry brief brings a hilariously cheesy solution - the Ipren man literally sings his own praises (and probably exactly what was in the brief):

"I am Ipren, the intelligent pain reliever, against pain and fever I'm efficient, painkilling, fever reducing - I'm simply intelligent - I have anti inflammation properties, I can handle muscle pain back pain and joint pain, one Ipren a 400 milligram works often better than two prescription-free tablets of paracetamol for example "Alvedon" for headaches, menstrual pain and toothaches..*inhale* I am Ipren the intelligent pain-killer."
