ATIMOS, known generically as formoterol, is a long-acting bronchodilator used in the management of asthma and chronic obstructive pulmonary disease (COPD). It functions by relaxing the muscles in the airways, thereby increasing airflow to the lungs and making breathing easier for individuals suffering from breathing difficulties. ATIMOS is typically administered through inhalation, allowing for direct action in the lungs with a rapid onset of effect. It is often prescribed as part of a long-term treatment regimen and is used regularly to prevent asthma attacks or exacerbations of COPD, rather than for immediate relief of acute symptoms. Patients are advised to follow their healthcare provider's instructions closely when using ATIMOS to ensure optimal safety and effectiveness.
