What is Zecuity? How does it work (mechanism of action)?
- Sumatriptan iontophoretic transdermal system (Zecuity) is anti-migraine drug that is delivered through the skin or transdermally. It is a serotonin (5HT) 1b/1d receptor agonist that is used for the acute treatment of migraine headaches in adults.
- Zecuity contains the drug, sumatriptan, which has been previously available as tablets, injections, and nasal spray. As the exact cause of migraine headaches remains unclear, the mechanism by which sumatriptan helps to this type of headache is not well understood. However, it is thought that sumatriptan helps to alleviate migraine pain by decreasing the dilation of blood vessels in the brain and inhibiting the release of inflammatory chemicals in the brain. This drug is designed to deliver sumatriptan through the skin with application of a battery operated device on the upper arm or thigh of the patient.
- This drug was approved by the FDA in January, 2013.
- Zecuity is the brand name for sumatriptan iontophoretic transdermal system available in the US.

What is the dosage for Zecuity?
- The patch delivers sumatriptan, a commonly used medication for
migraine through a transdermal system in which the drug is absorbed through the
skin. - Each patch delivers 6.5 mg of medication over four hours by using a low
electrical current (iontophoresis) and is powered by two coin cell lithium
batteries. - Patients may use up to 2 patches in 24 hours, and the second patch should not
be used any sooner than 2 hours after the activation of the 1st. Patients should
only use four patches per month. - Patches can be applied to the upper arm or thigh of the patient.
- The patches are about 8 inches long and 4 inches wide and are to be worn only
on unbroken skin and to an area relatively free of hair. - Once applied the patch must be activated by pushing a button to turn on the
device within 15 minutes. - A red light indicates that the patch is on and is delivering medication
to the patient. - The red light turns off when dosing is complete and patients may then remove
the patch. - Used patches must be folded and discarded in accordance with state and local
regulations as patches contain lithium-manganese dioxide.
