Could nasal delivery be the route of administration for your new drug? This route is not only reserved for decongestants or anti-inflammatory compounds. Nasal delivery is a very effective and non-invasive route to administer drugs.
For some compounds, delivery of drugs via the nasal route provides direct access to systemic absorption, and this route is probably one of the most non-invasive methods of bypassing the Blood Brain Barrier for delivering drugs targeted for CNS disorders.
Several examples of COVID prevention formulas, biological drugs, and vaccines can be administered via a nasal spray or nebulizer. No matter the drug type, patient safety can be ensured by preserving your formulation with a broad-spectrum, robust, and cost-effective antimicrobial, like Benzalkonium Chloride.
