Introduction to Flonase
Flonase, a popular over-the-counter medication containing fluticasone propionate, is a nasal spray widely used to combat allergies and nasal congestion. This synthetic corticosteroid mirrors the effects of natural hormones produced by the body's adrenal glands and helps reduce inflammation in the nasal passages.
The Science Behind Flonase
Mechanism of Action
Flonase works by targeting inflammation in the nasal passages during allergic reactions through several key processes:
- Blocking inflammatory chemicals
- Reducing blood vessel leakage
- Decreasing mucus production
- Preventing immune cell activation
When allergens enter the nasal passages, the body's immune system responds by releasing chemicals like histamines. Fluticasone propionate reduces inflammation by:
- Inhibiting inflammatory mediators: It prevents immune cells from releasing chemicals that cause inflammation
- Increasing anti-inflammatory cytokines: Promotes the production of substances like interleukin-10 (IL-10)
- Decreasing adhesion molecules: Reduces inflammatory cell recruitment to nasal tissues
Onset of Action
While some users report improvement within 12 hours, optimal results typically occur after several days of consistent use.
