Which of the following applies to doxapram?

• A. It acts as an analgesic
• B. It combats respiratory depression
• C. It reduces blood pressure
• D. It enhances sedation

Answer: (B)

Doxapram is a respiratory stimulant. Its primary action is to increase respiratory drive by stimulating brainstem centers and peripheral chemoreceptors, which boosts ventilation when breathing is depressed by anesthesia, sedatives, or other depressants. This makes it effective for counteracting respiratory depression and helping restore adequate breathing.

It is not an analgesic, so it does not relieve pain. It also does not reduce blood pressure; in fact, it can raise heart rate and blood pressure due to sympathetic activation. It does not enhance sedation; rather, it tends to promote wakefulness and improved respiration.
