The particular kind and degree of sleep apnea determine which drug is best. The main treatment for obstructive sleep apnea is continuous positive airway pressure (CPAP) therapy, which helps to maintain the airway open while you sleep. However, drugs like (modafinil) may be taken into consideration for certain people who are unable to tolerate CPAP or who continue to experience symptoms after therapy. Modalert 200 is a wakefulness-promoting medication that helps help people with sleep apnea be more alert during the day and perform better cognitively. It is commonly used as CPAP's adjuvant therapy and may improve the afflicted people's general quality of life.
