Ephedrine and pseudoephedrine are both stimulant medications, but ephedrine affects the heart and lungs more, while pseudoephedrine primarily targets nasal decongestion.
Key Differences

Ephedrine is widely recognized for its weight-loss and muscle-building applications; conversely, pseudoephedrine is largely appreciated for its efficacy in alleviating nasal congestion.
Ephedrine is frequently associated with more side effects and has wider systemic impacts, while pseudoephedrine is generally considered safer with restricted localized effects.
Regulation varies for ephedrine due to its misuse and side effects, while pseudoephedrine, although regulated, is typically more readily available in pharmacies.
