Peyona, also known by its generic name caffeine citrate, is a central nervous system stimulant medication primarily used in the medical field to treat apnea of prematurity (AOP) in newborns. Apnea of prematurity is a condition characterized by the cessation of breathing in premature infants for 20 seconds or longer, which can lead to decreased oxygen levels in the blood and other complications. Peyona works by stimulating the respiratory center in the brain, thereby increasing the rate and depth of breathing. This medication is administered either orally or intravenously, depending on the specific needs and condition of the infant. It is important for Peyona to be administered under the supervision of a healthcare professional to ensure the safety and effectiveness of the treatment.
