title: Diclofenac potassium powder for oral solution: a review of its use in patients with acute migraine.
abstract: Diclofenac potassium powder for oral solution (Voltfast(®), Catafast(®), Cambia(®); hereafter referred to as diclofenac potassium powder) is a non-steroidal anti-inflammatory drug (NSAID), and is indicated for the acute treatment of migraine. This article reviews the pharmacological properties of diclofenac potassium powder and its efficacy and tolerability in patients with acute migraine. Diclofenac potassium powder was clinically efficacious and generally well tolerated in placebo-controlled trials in patients with this indication; it was more effective than diclofenac potassium tablets with regard to the primary endpoint of 2-h pain relief as well as in several important secondary endpoints, such as time to onset of analgesic action. The oral powder-for-solution formulation of diclofenac potassium is a useful option in the acute treatment of migraine with or without aura.
