Final answer:
The first-line treatment for nasal polyps is topical corticosteroids, as they directly address the inflammation causing the polyps. Other treatments like nasal decongestants, antihistamines, and antibiotics have their roles, particularly in managing symptoms or secondary infections.
Step-by-step explanation:
The first-line treatment for nasal polyps is c) Topical corticosteroids. These medications help to reduce the inflammation in the nasal passages, which can shrink the polyps and alleviate symptoms. While nasal decongestants and antihistamines may be used to manage some symptoms associated with nasal polyps, they do not address the polyps directly like topical corticosteroids do. Antibiotics are not typically used unless there is a secondary infection present.
In terms of hypersensitivity reactions, antihistamines and anti-inflammatory steroid treatments are commonly used. For anaphylactic shock, however, the primary drug used is epinephrine. Antihistamines may also be used adjunctively in the treatment of milder allergic reactions.
Air in the nasal passages plays an important role by warming and humidifying the inhaled air to ward off infection, decrease sensitivity during breathing, and prevent damage to the lungs. Cilia also help by moving mucus and trapped pathogens out of the body, serving as an essential part of the immune defense mechanism.
