It is a calcium antagonist accompanied with L-type and N-type calcium channel blocking functions. Unlike other calcium antagonists, cilnidipine can act on the N-type calcium channel in addition to acting on the L-type calcium channel.

It was patented in 1984 and approved for medical use in 1995.[1]

Medical usesEdit

Cilnidipine decreases blood pressure and is used to treat hypertension and its comorbidities. Due to its blocking action at the N-type and L-type calcium channel, cilnidipine dilates both arterioles and venules, reducing the pressure in the capillary bed. Cilnidipine is vasoselective and has a weak direct dromotropic effect, a strong vasodepressor effect, and an arrhythmia-inhibiting effect. Blood pressure control with cilnidipine treatment in Japanese post-stroke hypertensive patients [The CA-ATTEND study] - the results of a large-scale prospective post-marketing surveillance study of post-stroke hypertensive patients (n = 2667, male 60.4%, 69.0 ± 10.9 years) treated with cilnidipine indicate that ilnidipine was effective in treating uncontrolled blood pressure and was well tolerated in post-stroke hypertensive patients.[2] The Ambulatory Blood Pressure Control and Home Blood Pressure (Morning and Evening) Lowering By N-Channel Blocker Cilnidipine (ACHIEVE-ONE) trial is a large-scale (n=2319) clinical study on blood pressure (BP) and pulse rate (PR) in the real world with use of cilnidipine - this study revealed that Cilnidipine significantly reduced BP and PR in hypertensive patients at the clinic and at home, especially with higher BP and PR in the morning.[3]

Side effectsEdit

The side effects could be severe diziness, fast heartbeat, and swelling of face, lips, tongue, eyelids, hands and feet. Lesser side effects include stomach pain, diarrhea and hypotension.

Peripheral edema, a common side effect from the use of amlodipine, was reduced when patients were shifted to cilnidipine.[4]

HistoryEdit

It was jointly developed by Fuji Viscera Pharmaceutical Company and Ajinomoto, and was approved to enter the market and be used as an anti-hypertensive in 1995.[citation needed]

Brand namesEdit

In Bangladesh, cilnidipine is marketed by The ACME Laboratories Ltd and Opsonin Pharma Limited under the brand names Duocard,and CILDIP, respectively, available as both 5 mg and 10 mg. In India it is marketed by JBCPL(JB Chemicals and Pharmaceuticals)[expand acronym] under the brand name Cilacar and by Lloyd under the brand name Cilidin, and by kronos healthcare under the brand name Cilush it is available in 5 mg, 10 mg, 20 mg and other doses. In Japan it is marketed by Ajinomoto Pharmaceuticals under the brand name Atelec. In the United States it is available through different brands, including Atelec and Cilacar.
