Potassium channel opener

A potassium channel opener is a type of drug which facilitates ion transmission through potassium channels.

Some examples include:

  • Diazoxide[1] vasodilator used for hypertension, smooth muscle relaxing activity
  • Minoxidil[2] vasodilator used for hypertension, also used to treat hair loss
  • Nicorandil[3] vasodilator used to treat angina
  • Pinacidil[4]
  • Retigabine,[5][6] an anticonvulsant
  • Flupirtine, analgesic with muscle relaxant and anticonvulsant properties
