Central alpha-2 Adrenergic Agonist
An Established Pharmacologic Class (EPC) in the FDA NDC Directory: the class FDA records for a product in its PHARM_CLASSES field.
In the NADAC file of 2026-10-14
25 products in the NADAC file of 2026-10-14 have an NDC that FDA lists in this class, covering 10 nonproprietary names as FDA writes them. 19 of them have a Medicare figure on OpenBill.
Being in one class means FDA describes the drugs’ pharmacology the same way. It does not mean one can replace another; that is a question for your prescriber.

How to read these prices
OpenBill holds every page to these five rules, written by the project’s owner and quoted word for word:
- A price is a range to expect, never a quote.
- Medicare's price is not your price. Say so on every screen that shows it.
- State which dataset and which effective date produced every figure.
- If a source is stale or a file is empty, show that rather than a zero.
- Disclaimer footer: not medical advice, no warranty, other people's data can be wrong.
