What is the dosage form of Esketamine?

Esketamine is primarily available as a nasal spray, which is significant because this delivery method allows for a rapid onset of action in treating conditions like depression. The nasal spray formulation is designed to be administered under the supervision of a healthcare provider to monitor for any potential side effects and to ensure proper dosage. This route is particularly advantageous for patients who may have difficulty with oral medications or for those who require quick therapeutic effects.

By being delivered through the nasal mucosa, Esketamine can bypass some of the metabolic processes that occur with oral medications, allowing for more effective absorption into the bloodstream. This aspect is crucial in the context of treating treatment-resistant depression where swift intervention is often needed.

The other dosage forms, such as tablets or injections, do not provide the same rapid action or specific use in the context of Esketamine’s approved treatment protocols.
