💧 Midazolam Nasal Spray 0.5 mg
📘 Description:
Midazolam Nasal Spray 0.5 mg is a benzodiazepine formulation designed for intranasal delivery, primarily used to quickly control acute seizures or panic episodes. It offers rapid absorption through nasal mucosa, especially in emergency situations where intravenous access may not be available.
