Therapeutic Options, Drug Classes, and Delivery Formulations
Managing allergic rhinitis involves a combination of environmental control measures, pharmacotherapy, and allergen immunotherapy. Depending on whether symptoms are seasonal or perennial, medical professionals tailor treatment regimens to control local mucosal inflammation and suppress histamine release.
Therapeutic offerings are typically categorized by drug mechanism and delivery route:
-
Antihistamines (Oral and Intranasal): Second- and third-generation oral antihistamines block H1 receptors to relieve itching, sneezing, and runny nose without severe sedation. Intranasal antihistamines offer rapid localized action.
-
Corticosteroids (Intranasal Sprays): Widely considered the first-line therapy for moderate-to-severe rhinitis, steroid sprays directly reduce nasal tissue swelling and mucus hypersecretion.
-
Decongestants and Leukotriene Receptor Antagonists: Oral or topical decongestants relieve acute congestion, while leukotriene modifiers help manage co-existing allergic asthma and persistent airway inflammation.

| Therapeutic Class | Primary Mechanism of Action | Typical Delivery Format |
+---------------------------------+----------------------------------------+---------------------------------------+
| H1 Antihistamines | Selective histamine receptor block | Oral tablets, liquids, nasal sprays |
| Intranasal Corticosteroids | Localized anti-inflammatory suppression| Metered-dose nasal sprays |
| Leukotriene Receptor Antagonists| Blocks inflammatory leukotrienes | Oral tablets |
| Allergen Immunotherapy (AIT) | Desensitizes immune response over time | Sublingual drops/tablets, injections |
