How is Diastat administered?

Diastat, which contains the active ingredient diazepam, is specifically formulated for rectal administration. This method is particularly effective for individuals experiencing seizure episodes, as it allows for rapid absorption into the bloodstream through the rectal mucosa. The rectal route is advantageous because it can be administered quickly and without the need for IV access, making it a practical option during a seizure emergency when time is of the essence.

Oral administration is incorrect, as it would not provide the necessary rapid absorption needed during a seizure. Intravenous and subcutaneous routes are also inappropriate considering the common usage of Diastat, which is designed for situations where immediate action is necessary, and rectal administration is the fastest and least invasive method for that purpose.
