What is the primary use of a therapeutic drug?

The primary use of a therapeutic drug is to relieve symptoms and manage diseases. Therapeutic drugs are specifically designed to treat medical conditions by targeting the underlying causes of diseases or alleviating symptoms. They play a crucial role in disease management by providing effective relief, improving patient quality of life, and sometimes addressing the root causes of conditions through various mechanisms of action.

For instance, in conditions like hypertension, therapeutic drugs, such as antihypertensives, help manage blood pressure levels, thereby reducing the risk of complications like heart attack and stroke. Additionally, therapeutic drugs can also be used for symptom relief, such as analgesics for pain relief or antihistamines for allergy symptoms.

While other options, such as preventive care, patient education, and facilitating research studies, are important aspects of healthcare, they do not specifically capture the primary role of therapeutic drugs in directly managing and treating diseases.
