Histopharmacology of bronchus

 

Cough is the most nasty symptom of bronchial infection or irritation. It can be stopped with the use of anti-tussives such as water aerosol inhalations, often with menthol. It may also be neccessary to give opioids which act centrally such as codeine or methadone.

Mucolytics can be beneficial if mucus being produced is too viscous. Mucolytic include steam  inhalation, carbocisteine or mecysteine. Aerosols and sprays act on bronchi and may be used to relied symptoms of asthma which may cause bronchospasms and they include β₂ adrenergic receptor agonists such as salbutamol or terbutaline. Epinephrine (a potent β₂ adrenergic receptor) is given parenterally in cases of status asthmaticus. In asthma bronchspasm due to smooth muscle contraction occurs as a result of allergic response. Adrenergic antagonism is the treatment.
