Midazolam Nasal Spray 1.25 mg
📘 Description:
Midazolam Nasal Spray 1.25 mg is a benzodiazepine sedative in a metered-dose nasal spray form, used primarily for rapid control of acute seizures, procedural sedation, or severe anxiety. The intranasal route enables quick absorption through nasal mucosa, making it ideal in emergency or non-clinical settings when IV access is unavailable.
🔹 Formulation:
- Active Ingredient: Midazolam hydrochloride
- Strength: 1.25 mg per spray (per actuation)
- Form: Aqueous nasal solution
- Route of administration: Intranasal
- Packaging: Pre-metered spray bottle (multi- or single-dose)
🧪 Nature / Mechanism of Action:
Midazolam acts on the GABA-A receptors in the central nervous system, enhancing the inhibitory neurotransmitter GABA. This leads to:
- Sedation
- Anxiolysis
- Muscle relaxation
- Anticonvulsant effects
Intranasal absorption results in fast onset (within 5–10 minutes).
