  • COPD chronic obstructive pulmonary disease
  • bronchia are the channels which function to distribute the inhaled air into the lung tissues.
  • respiratory diseases such as asthma or chronic obstructive pulmonary disease (COPD)
  • stimulants such as allergen, infection, good and bad smell, smoke, genetic factors and exercise cause contractions in the airway muscles (bronchoconstruction) and/or excessive secretion in glands and results in contractions in the airway.
  • bronchoconstruction obstructive pulmonary disease
  • respiration gets more difficult as the inhaled air cannot be exhaled.
  • Corticosteroids which are used in the treatment of asthma and COPD are synthetic and strong anti-inflammatory drugs that are similar to natural corticosteroid hormones produced by adrenal glands. They prevent both the transcription of the inflammatory gene and the activation of the anti-inflammatory gene.

  • Corticosteroids are not preferred in acute asthma crises as they do not have rapid onset of action. Since inhaled corticosteroids may prevent growth in children, they are advised to be used in the lowest possible amount. Long-term use of corticosteroids may cause cataract and glaucoma. In addition, they may cause some serious side-effects such as osteoporosis, high cholesterol, edema, encepholalgia, weight gain, insomnia and some skin problems.
  • Anticholinergics are the other active agents which are utilized in the treatment of respiratory disorders. Anticholinergics affect muscarinic receptors and prevent the obliteration in the bronchia due to excessive secretion. These drugs are categorized into two groups as long-acting and short-acting.

  • Antistatic agents are basically classified into two groups: internal antistatic agents and external antistatic agents. Internal antistatic agents are designed to be mixed directly into the material whereas external antistatic agents are applied to the surface.
  • Antistatic agents used within the scope of the invention are selected from a group comprising long-chain aliphatic amines (optionally ethoxylated) and amides, glycerol monostearate (GMS), saturated fatty acids, (poly)unsaturated fatty acids, quaternary ammonium salts (e.g., behentrimonium chloride or cocamidopropyl betaine), sulfonated organic compounds, esters of phosphoric acid, polyethylene glycol esters, polyols and combinations thereof. Also, some commercially available antistatic additives such as OnCapTM, Larostat ®, EntiraTM, Nourymix®, can be used as antistatic agents. It is also possible to use conductive polymers like PEDOT:PSS and conducting polymer nanofibers, particularly polyaniline nanofibers.
