Maximum Dose of Amlodipine
The maximum recommended dose of amlodipine is 10 mg once daily for adults, as specified by the FDA label and supported by all major cardiology guidelines. 1
Standard Adult Dosing
- The FDA-approved dosing for amlodipine begins at 5 mg once daily as the usual initial antihypertensive dose, with a maximum of 10 mg once daily 1
- For small, fragile, or elderly patients, or those with hepatic insufficiency, the starting dose should be reduced to 2.5 mg once daily 1
- The American College of Cardiology confirms the standard adult dosing range of 2.5-10 mg once daily, with 5-10 mg being the typical therapeutic range 2
Titration Strategy
- When adjusting the dose, wait 7 to 14 days between titration steps under normal circumstances 1
- More rapid titration is acceptable if clinically warranted, provided the patient is assessed frequently 1
- Clinical trial data demonstrates that dose increases from 5 mg to 10 mg should not be considered until after 6 weeks of treatment, as there is no advantage to early dose escalation in terms of antihypertensive effect 3
Indication-Specific Dosing
- For hypertension: The maximum dose is 10 mg once daily 1
- For chronic stable or vasospastic angina: The recommended dose range is 5-10 mg once daily, with most patients requiring 10 mg for adequate symptom control 1, 4
- For coronary artery disease: The recommended dose range is 5-10 mg once daily, with the majority of patients in clinical studies requiring 10 mg 1
Pediatric Maximum Dose
- In pediatric patients ages 6-17 years, the maximum dose is 5 mg once daily 1
- Doses exceeding 5 mg daily have not been studied in pediatric patients and should not be used 1
Pharmacokinetic Rationale
- Amlodipine's long elimination half-life of approximately 30-50 hours (up to 64 hours in elderly patients) supports once-daily dosing and maintains effective blood levels throughout the 24-hour dosing interval 2, 5
- The gradual absorption after oral administration produces gradual vasodilation, reducing reflex tachycardia and headache compared to other calcium antagonists 4
