About Cilnidipine
Indications of Cilnidipine
Established Use
Cilnidipine is indicated for the treatment of essential hypertension (high blood pressure) in adults. It is used to lower blood pressure and, by doing so, reduce the risk of hypertension-related complications such as stroke and cardiovascular events.
Guideline-Supported / Preferential Use
Cilnidipine is particularly favored in hypertensive patients who also have diabetes mellitus, albuminuria (protein in urine), or chronic kidney disease, because its additional N-type calcium channel blocking action may offer a degree of renal protection and reduced glomerular capillary pressure compared with conventional dihydropyridine calcium channel blockers. It may also be preferred in patients prone to reflex tachycardia or sympathetic activation on standard dihydropyridine calcium channel blockers.
Combination Therapy
In patients whose blood pressure is not adequately controlled on Cilnidipine alone, it may be combined with other antihypertensive classes such as angiotensin receptor blockers (ARBs), ACE inhibitors, or diuretics, under physician supervision.
Dosage & Administration of Cilnidipine
General Dosing Principles
Cilnidipine is administered orally, once daily. Treatment is typically started at a low dose and adjusted by the physician based on blood pressure response and tolerability.
| Indication | Adult Dose | Notes |
|---|---|---|
| Essential hypertension (initial therapy) | 5 mg orally once daily, preferably after breakfast | May be increased gradually based on response |
| Essential hypertension (maintenance/inadequate response) | 10 mg orally once daily | Usual effective maintenance dose |
| Maximum dose | Up to 20 mg once daily | Only under close physician supervision in patients with inadequate response |
Elderly patients: Initiate at the lowest available dose (5 mg once daily) due to increased susceptibility to hypotension, and titrate cautiously.
Renal impairment: Use with caution; no fixed dose reduction is well-established, but close monitoring of blood pressure is advised, particularly in significant renal impairment.
Hepatic impairment: Since Cilnidipine is extensively metabolized by the liver, use with caution and reduced dose in patients with hepatic impairment; avoid in severe hepatic dysfunction unless directed by a physician (see Precautions and Warnings).
Side Effects of Cilnidipine
Side effects of Cilnidipine are generally mild to moderate and dose-related, consistent with its vasodilatory calcium channel blocking action.
Common
- Dizziness
- Flushing
- Headache
- Palpitations
- Peripheral (ankle) edema
- Increased frequency of urination (nocturnal/daytime)
Less Common
- Gastrointestinal disturbances (nausea, dyspepsia, constipation)
- Lethargy or fatigue
- Gum hyperplasia (rare, class effect of dihydropyridines)
- Elevated liver enzymes (rare)
Patients should seek medical advice if side effects are persistent, severe, or accompanied by symptoms such as fainting, chest pain, or significant swelling.
Contraindications of Cilnidipine
Cilnidipine is contraindicated in patients with:
- Known hypersensitivity to Cilnidipine or to any component of the formulation, or to other dihydropyridine calcium channel blockers.
- Cardiogenic shock.
Other conditions such as severe hepatic impairment, recent myocardial infarction, unstable angina, and pregnancy are important precautions requiring careful risk-benefit assessment rather than absolute contraindications in all cases; see Precautions and Warnings and Pregnancy and Lactation for details.
Frequently Asked Questions about Cilnidipine
What is Cilnidipine used for?
Cilnidipine is used to treat high blood pressure (hypertension) in adults. It works by relaxing blood vessels to help blood flow more easily, and it is often preferred in patients who also have diabetes, protein in the urine, or kidney disease.
How is Cilnidipine different from other calcium channel blockers like amlodipine?
Cilnidipine blocks both L-type and N-type calcium channels, whereas most other dihydropyridine calcium channel blockers (like amlodipine) block only L-type channels. This dual action may result in less reflex increase in heart rate and, in some patients, less ankle swelling, although individual results can vary.
When should I take Cilnidipine?
Cilnidipine is usually taken once daily, preferably after breakfast, at the same time each day. Follow your physician's specific instructions regarding dose and timing.
Can I drink grapefruit juice while taking Cilnidipine?
No. Grapefruit juice can increase the amount of Cilnidipine in your blood by interfering with how your liver breaks it down, which can increase the risk of side effects such as low blood pressure and dizziness. It is best to avoid grapefruit and grapefruit juice while taking Cilnidipine.
What are the common side effects of Cilnidipine?
Common side effects of Cilnidipine include dizziness, flushing, headache, palpitations, mild swelling of the ankles or feet, and increased frequency of urination. Most side effects are mild, but you should contact your doctor if they are severe or persistent.
Is Cilnidipine safe during pregnancy or breastfeeding?
The safety of Cilnidipine during pregnancy and breastfeeding has not been well established. Cilnidipine should only be used in pregnancy if clearly needed and the potential benefit outweighs the potential risk, and a decision about breastfeeding while taking Cilnidipine should be made in consultation with your physician.
