Generic name: Theophylline / Guaifenesin
Quibron is a medicine to prevent/treat airway blockage and symptoms associated with lung diseases including asthma, bronchitis, or emphysema. It may also be used by your physician to treat certain other conditions.
It refers to expectorants and xanthine derivatives combination.
The xanthine derivative relaxes smooth muscles around the air passages (bronchial tubes), thus widening the tubes and making easier breathing.
It improves the diaphragm contraction (the main breathing muscle). The expectorant loosens the airway mucus and increases respiratory secretions
