Used as a respiratory stimulant to treat post-anesthesia respiratory depression and in cases of drug-induced respiratory suppression. It works by stimulating the brain’s respiratory center to increase breathing rate and depth. Commonly administered in clinical settings during recovery from anesthesia or in emergency situations involving acute respiratory insufficiency. Also used in neonatal care to manage apnea in premature infants. Its action is fast but short-lived, requiring careful monitoring during use.
