Nasal spray
Nasal Spray
A Nasal spray (/ˈneɪzəl spreɪ/) is a form of medication that is designed to be inhaled through the nose. It is used to treat a variety of conditions, including allergies, sinus infections, and nasal congestion.
Etymology
The term "nasal spray" is derived from the Latin "nasus" meaning "nose" and the English "spray" meaning "to scatter or disperse liquid in a shower or mist".
Usage
Nasal sprays are typically used to deliver medication directly to the nasal mucosa, the moist, inner lining of the nose. This allows for a faster onset of action compared to oral medications and reduces systemic side effects.
There are several types of nasal sprays, including decongestant sprays, steroid nasal sprays, antihistamine sprays, and saline nasal sprays. Each type of spray works in a different way and is used to treat different symptoms or conditions.
Related Terms
- Decongestant sprays: These sprays work by constricting the blood vessels in the nasal passages, reducing swelling and congestion.
- Steroid nasal sprays: These sprays reduce inflammation in the nasal passages, often used for allergies or sinus infections.
- Antihistamine sprays: These sprays block the action of histamine, a chemical that the body releases during an allergic reaction.
- Saline nasal sprays: These sprays help to moisturize the nasal passages and clear out mucus and allergens.
