Final answer:
The drugs prescribed for long-term control of pulmonary pathologies, such as asthma and COPD, are preventive in nature, like corticosteroids, and are not used for acute deterioration, which is instead treated with fast-acting bronchodilators.
Step-by-step explanation:
The property that characterizes drugs commonly prescribed for long-term control of pulmonary pathologies, such as chronic obstructive pulmonary disease (COPD) and asthma, but not used for acute phases by EMTs, is their preventive nature. These are maintenance medications, like corticosteroids, which are effective over time to reduce inflammation and prevent exacerbation of the disease. In contrast, acute exacerbations are commonly treated with fast-acting bronchodilators, which provide immediate relief by opening up the constricted airways to facilitate easier breathing.
These long-term medications work gradually and are not suitable for emergency situations where immediate relief is required. An important aspect of managing chronic pulmonary diseases like asthma and COPD involves both preventing attacks with maintenance medications, and treating acute episodes with quick-acting drugs.
