Voltaren Emulgel Science - Diclofenac

Acts through cyclo-oxygenase-2 (COX-2) inhibition, striking inflammation at its source

Learn how diclofenac reduces inflammation by inhibiting prostaglandin biosynthesis through action on the COX enzymes with selectivity for COX-2, and inhibiting phospholipase A2 activity to reduce the production of inflammatory leukotrienes.1,2,4

Relative potency of diclofenac, ketoprofen and ibuprofen

Diclofenac is a potent anti-inflammatory agent1

Its effect on the COX-2 enzyme means that, unlike non-NSAID medications such as paracetamol, diclofenac not only provides pain relief but also treats inflammation – a root cause of pain.2,4

Diclofenac, an NSAID (and therefore in the same drug class as ketoprofen and ibuprofen), shows marked potency in its inhibition of the COX-2 enzyme.5

Voltaren Emulgel penetration over time

On its own, diclofenac does permeate the skin. However, VoltarenEmulgel is specially designed to aid diclofenac’s entry into and transit through the skin. It delivers diclofenac across the skin faster than a diclofenac solution of the same concentration.*1
