Step-by-step explanation:
Hypnotics are a type of psychoactive medication used to promote sleep. These drugs, such as barbiturates and benzodiazepines, work by depressing the central nervous system, leading to sedation and making it easier for individuals to fall asleep. Unlike some analgesic or anti-inflammatory medications, hypnotics are specifically formulated to help with sleep issues. Barbiturates, like phenobarbital and pentobarbital, have been largely replaced by benzodiazepines and nonbenzodiazepine hypnotics due to concerns such as addiction and overdose potential. Therefore, the correct completion for the statement 'Hypnotics are used to _________' would be option (d) promote sleep. Hypnotic medications are drugs that induce sleep or promote a state of drowsiness, making them useful for individuals who have difficulty falling asleep or staying asleep. They are commonly prescribed for the treatment of insomnia and other sleep disorders.
