Voltarol – for effective relief of body pain

Relative potency of diclofenac, ketoprofen and ibuprofen

Diclofenac is a potent anti-inflammatory ingredient1

Most Voltarol products include the potent non-steroidal anti-inflammatory drug (NSAID), diclofenac.1,2

This active ingredient targets pain at its source by reducing inflammation.1,3

Products that match patient needs

The Voltarol family of products contains a range of solutions to suit your patient's requirements, including:

  • A selection of formulations – including topical gels and non-medicated patch
  • Products based on either the active ingredient diclofenac or non-drug technology

The science behind Voltarol


Targeting pain with the potent anti-inflammatory effects of diclofenac1

Diclofenac reduces inflammation by inhibiting prostaglandin biosynthesis through action on the cyclo-oxygenase (COX) enzymes. Diclofenac exerts its therapeutic effects primarily through inhibition of prostaglandin synthesis by COX-2. It also reduces the production of leukotrienes by inhibiting phospholipase A2 activity.3

Diclofenac not only provides pain relief but also treats inflammation – a root cause of pain.
