What are the most common inhaled anesthetics?

The inhalation anaesthetic agents have changed over the years. The most commonly used agents today are nitrous oxide, isoflurane, sevoflurane and desflurane. In the past, we used halothane and methoxiflurane, but they have historic interest only at this point. This is because, they had side effects and organ toxicity, and have been essentially discontinued. The new inhalation anaesthetics are safer, cleaner, and they have a more rapid onset and a more rapid offset.
