What is the Catapres TTS patch used for?
The Catapres TTS patch is a transdermal patch that delivers the medication clonidine, a centrally acting alpha-2 adrenergic agonist. It's primarily used to treat [1] high blood pressure (hypertension), attention deficit hyperactivity disorder (ADHD), anxiety disorders, withdrawal (from opioids and nicotine), and migraines.
How does it work?
Clonidine works by stimulating alpha-2 receptors in the brain, which leads to a decrease in sympathetic nervous system activity. This results in lower blood pressure, heart rate, and blood vessel constriction. Clonidine also has a calming effect on the central nervous system, making it a useful treatment for certain anxiety disorders and ADHD.
Side effects and precautions
Common side effects of the Catapres TTS patch include drowsiness, dry mouth, headaches, dizziness, and constipation. More serious side effects can include fainting, low blood pressure, and increased heart rate. Patients should be monitored for these potential risks, especially when the patch is first applied.
Dosage and administration
The Catapres TTS patch is available in several different strengths, with each patch lasting a specific length of time (e.g., 7 days). The patch is applied to the skin, usually on the upper body or lower back. The dosage can be adjusted based on individual patient needs and response to treatment.
Interactions and contraindications
Patients should inform their healthcare provider about any medications they're currently taking, as clonidine can interact with certain drugs. The Catapres TTS patch is contraindicated in patients with certain medical conditions, such as heart problems, kidney disease, or pheochromocytoma.
When does patent expire?
According to DrugPatentWatch.com, the Catapres TTS patent has expired in various countries (e.g., in the US, it's available as a generic medication) [2].
