Intranasal (IN) administered midazolam has allowed patients who require conscious sedation but struggle to tolerate cannulation another option by which they can receive dental treatment. Studies have demonstrated that a mean bioavailability (F) of more than 73% can be achieved with IN-administered midazolam. This is due to the high vascularity within the nose. These studies have also demonstrated that peak plasma concentrations can be reached within 10 minutes. This signifies a fast onset of action. The standard bolus dose of IN midazolam is 10mg; this bolus can be reduced or increased depending on the patient's age and susceptibility to benzodiazepines. The bolus can also be repeated if adequate sedation is not reached. A protocol for administering IN midazolam is outlined and two cases are discussed.
