An estimated 17.7 million adults in the U.S. have asthma, a condition often treated with a drug mist. A **drug mist** is not a specific medication, but rather a descriptive term for a drug delivery method that turns liquid or powdered medicine into a fine spray or aerosol, which can be easily inhaled or absorbed through nasal passages. This innovative approach is used to treat a wide array of respiratory and other systemic conditions by delivering medication directly to the target site.

The nasal cavity's large surface area, approximately 160 cm², offers a unique and rapid route for drug administration [1.6.2]. Understanding **where do drugs absorb in the nose** is crucial for developing effective therapies that can bypass first-pass metabolism and even target the brain directly [1.6.2, 1.3.6].

While standard parasitic treatments are typically oral or topical, some specialized, custom-compounded medications exist for localized infestations; an example is an ivermectin nasal spray that has been documented in treating extremely rare cases of nasal maggot infestation. This delivery method is not a cure-all for parasites.

The blood-brain barrier (BBB) prevents nearly 100% of large-molecule drugs from entering the brain, posing a massive challenge for treating neurological disorders [1.3.4]. This article explores what is the use of neuro spray, an innovative delivery method designed to bypass this barrier.
