Guanadrel
Guanadrel
Guanadrel (pronunciation: gwa-NAD-rel) is a medication that belongs to the class of drugs known as sympatholytics. It is primarily used in the treatment of hypertension (high blood pressure).
Etymology
The term 'Guanadrel' is derived from the chemical structure of the drug, which is a guanidine derivative. The '-drel' suffix is common in drugs that affect the sympathetic nervous system.
Usage
Guanadrel works by blocking the nerve signals that cause the blood vessels to constrict, thereby helping to lower blood pressure. It is usually prescribed as part of a comprehensive treatment plan for hypertension, which may also include lifestyle changes such as diet and exercise.
