Cilnidipine Dosing: Maximum Dose and Frequency
The maximum daily dose of cilnidipine is 20 mg once daily, with a typical starting dose of 5-10 mg once daily.
Standard Dosing Regimen
Based on the available clinical evidence, cilnidipine follows this dosing pattern:
- Starting dose: 5-10 mg once daily 1, 2, 3, 4
- Maximum dose: 20 mg once daily 1, 3, 4
- Frequency: Once daily administration
The once-daily dosing is supported by multiple studies demonstrating sustained 24-hour blood pressure control with single daily administration 2, 3, 4.
Dose Titration
When initiating therapy:
- Begin with 5-10 mg once daily
- May increase to 20 mg once daily based on blood pressure response
- The dose escalation typically occurs after 4-8 weeks of treatment to assess efficacy 1, 3, 5
Clinical Context
Cilnidipine is a unique L-type and N-type calcium channel blocker that provides effective blood pressure reduction comparable to other dihydropyridine calcium channel blockers 6. Key advantages include:
- No reflex tachycardia: Unlike amlodipine and nifedipine, cilnidipine does not significantly increase heart rate 3, 5, 4, 7
- Lower incidence of pedal edema: Significantly less ankle swelling compared to amlodipine 7
- Sustained 24-hour control: Effective throughout the day with once-daily dosing 2, 4
Important Caveats
Note: The FDA drug label information provided in the evidence 8 actually describes cyclobenzaprine (a muscle relaxant), not cilnidipine. This appears to be a data error. The dosing recommendations above are based on the research studies specifically evaluating cilnidipine as an antihypertensive agent [1-9].
The 20 mg maximum daily dose is consistently reported across multiple clinical trials conducted in hypertensive patients, with no studies using higher doses 1, 3, 4.
