Used primarily as a mild central nervous system stimulant, this compound helps enhance alertness and reduce fatigue. It is commonly found in over-the-counter medications for mild pain relief, often combined with analgesics to boost their effectiveness. Due to its ability to relax smooth muscles, it is also used in some respiratory formulations to aid in bronchodilation. Additionally, it appears in certain dietary supplements aimed at improving mental focus and physical endurance. Its moderate stimulant effect makes it suitable for daytime use without significant jitteriness or sleep disruption in normal doses.
