What is the duration of action for pancuronium?

30 minutes
45 minutes
60 minutes
90 minutes

The correct answer is: 45 minutes

The duration of action for pancuronium, a neuromuscular blocking agent used in anesthesia, is typically around 45 to 60 minutes. This time frame allows for effective muscle relaxation during surgical procedures, making it a practical choice among anesthetic agents. When considering the details, pancuronium is known for its intermediate duration, which is advantageous in various clinical situations that require controlled muscle paralysis without prolonged effects that might lead to extended recovery times. This characteristic aligns with its common usage in situations where moderate duration of neuromuscular blockade is needed, such as during surgery or intubation. In practice, healthcare professionals must also monitor individual patient responses, as factors such as body weight, age, and underlying health conditions can influence the drug's metabolism and excretion, potentially altering its duration of action.
