📚 Pseudoephedrine — full study notes
The cheat sheet above is your quick recall card. These notes go deeper — what it is, what to do first, what must be reported, and what to teach.
Pseudoephedrine is a sympathomimetic (alpha-adrenergic) decongestant that constricts nasal blood vessels to relieve congestion. Because it stimulates the cardiovascular and central nervous systems, it raises blood pressure and heart rate. It is sold behind the pharmacy counter because it can be diverted to make methamphetamine.
