Tekast ODT is a leukotriene receptor antagonist containing montelukast, widely used for the long-term management of asthma and allergic conditions. It helps prevent and control symptoms of bronchial asthma by reducing airway inflammation, bronchoconstriction, and mucus production. It is also effective in relieving seasonal and perennial allergic rhinitis, including symptoms such as sneezing, nasal congestion, and runny nose. Additionally, Tekast OTD is used for the prevention of exercise-induced bronchospasm, supporting better breathing during physical activity. By blocking leukotriene-mediated inflammatory pathways, it provides sustained respiratory protection and improves overall airway function. Tekast OTD is an important therapeutic option in respiratory allergy and asthma management, contributing to improved symptom control and enhanced quality of life in both adults and pediatric patients.
