التداخل بين بوتالبيتال وباراسيتامول وميثوهيكسيتال

Butalbital and acetaminophen may enhance the effects of:other narcotic analgesics, alcohol, general anesthetics, tranquilizers such as chlordiazepoxide, sedative-hypnotics, or other CNS depressants, causing increased CNS depression.

Apnea/hypoventilation may be noted during induction, which may impair pulmonary ventilation; the duration of apnea may be longer than that produced by other barbiturate anesthetics.
