The Duolin Forte inhaler is a combination medicine used to treat asthma and chronic obstructive pulmonary disease. It comprises two active ingredients: ipratropium bromide, an anticholinergic that opens the airways, and salbutamol, a beta-agonist that offers immediate relief by relaxing the muscles surrounding the airways. This dual-action technique improves breathing and alleviates respiratory symptoms like wheezing and shortness of breath. Duolin Forte is typically used for long-term maintenance rather than instant relief. It improves lung function and prevents exacerbations. Effective treatment requires proper use in accordance with medical instructions, as well as regular follow-ups with a healthcare provider.
