From the Guidelines
Amlodipine and minoxidil can be used together for treating resistant hypertension, with amlodipine helping to mitigate the reflex tachycardia caused by minoxidil, as suggested by the American Heart Association 1. When prescribed together, it is essential to monitor for potential side effects, including ankle swelling, dizziness, headache, and fluid retention. The dosage of amlodipine typically ranges from 2.5-10 mg once daily, while minoxidil is used at 5-40 mg daily in divided doses for severe hypertension. Key considerations for using these medications together include:
- Regular blood pressure checks, especially when starting or adjusting doses
- Monitoring for signs of fluid retention, which may require concomitant use of a diuretic
- Awareness of the potential for reflex tachycardia with minoxidil, which amlodipine can help counteract
- The importance of not adjusting doses without medical supervision due to the risk of significant blood pressure changes. The combination of amlodipine, a calcium channel blocker, and minoxidil, a potent vasodilator, can be effective in managing resistant hypertension, but treatment must be tailored to the individual patient, taking into account their specific needs and medical history 1.
From the Research
Amlodipine and Minoxidil
- Amlodipine is a calcium channel blocker used to treat high blood pressure and coronary artery disease 2.
- Minoxidil is a direct vasodilator used to treat resistant or severe hypertension, often in combination with other medications such as diuretics and beta blockers to counteract its side effects 3.
Comparison with Other Medications
- Felodipine, a calcium antagonist, has been compared to minoxidil in the management of severe hypertension, with similar blood pressure control but fewer side effects 4.
- Amlodipine has been used in combination with other medications, such as candesartan cilexetil and hydrochlorothiazide, to treat moderate-to-severe essential hypertension 2.
Treatment of Hypertension
- The treatment of hypertension often involves a combination of lifestyle modifications and antihypertensive therapies, with the goal of reducing blood pressure and minimizing the risk of cardiovascular disease 5.
- Angiotensin-converting enzyme inhibitors and angiotensin receptor blockers are commonly used to treat hypertension, with similar efficacy but differing side effect profiles 6.
