1. Mucolytic activity: N acetylcysteine has been used as a mucolytic agent in patients with pulmonary disease such as cystic fibrosis as well as chronic bronchitis and bronchiectasis for decades. It is usually delivered topically via a nebulizer or air supply solution. Studies have demonstrated benefits of pets mucolytic properties in breaking down disulfide bonds and decreasing viscosity of allergic medicine and thicker mucus secretions. These characteristics are obviously advantageous for patients with Allergic rhinitis as well as various forms of sinusitis.

2.  Anti-inflammatory and antioxidant characteristics: N-acetylcysteine has long been known to exhibit antioxidant properties with a reduction in free radicals and a scavenger of hydroxyl radicals. Numerous studies have now demonstrated activity of N-acetylcysteine in suppressing components of the inflammatory response. N-acetylcysteine has been shown to suppress production of cytokines such as into interleukin-6 and Tumor necrosis factor. Again, these are favorable properties in patients with inflammatory disease of the sink-nasal airway.

3. Effect of acetylcysteine on bio films: studies have now shown that N-acetylcysteine Has the ability to break down bio films such as those produced by staphylococcal aureus. This may be beneficial in patients with chronic bacterial sinusitis as well as bacterial nasal infections.

4. What time shall anti-infective properties Of NAC: N-acetylcysteine has been studied as a antiviral agent. This potential is still being fully explored for diseases such as influenza. Anti-bacterial and bacterial static properties of N-acetylcysteine have been demonstrated. In addition N-acetylcysteine has been shown to work synergistically with antibiotics in bacterial infection, especially in situations where bio films are evident.
