<strong data-start="110" data-end="123">Modafinil is a wakefulness-promoting agent primarily used to treat sleep disorders such as narcolepsy, obstructive sleep apnea, and shift work sleep disorder. It works by affecting neurotransmitters in the brain that regulate the sleep-wake cycle, helping individuals stay alert and focused throughout the day. Beyond its medical use, Modafinil is known for its off-label benefits, including improved concentration, mental clarity, and productivity. Often classified as a nootropic or &ldquo;smart drug,&rdquo; Modafinil is widely studied for its cognitive-enhancing properties. It is considered non-habit-forming and generally well-tolerated, making it a popular choice among professionals and students seeking sustained mental performance.
