Nasal Spray

Nasal sprays deliver medications either locally in the nasal cavities or systemically throughout the body, used locally for conditions such as nasal congestion and allergic rhinitis. The nasal route is sometimes preferred for systemic therapy because it offers an agreeable alternative to injection or pills, with substances absorbed extremely quickly and directly through the nose; pharmaceutical drugs delivered as nasal sprays include sedative analgesics and treatments for migraine, osteoporosis, and nausea, as well as hormone replacement therapy and treatments for Alzheimer's disease and Parkinson's disease, with the nasal route seen as an efficient way to transport drugs with potential to cross the blood brain barrier.
