Cilnipres N

Cilnipres N Uses, Dosage, Side Effects, Food Interaction and all others data.

Cilnidipine acts on the L-type calcium channels of blood vessels by blocking the incoming calcium and suppressing the contraction of blood vessels, thereby reducing blood pressure. Cilnidipine also works on the N-type calcium channel located at the end of the sympathetic nerve, inhibiting the emission of norepinephrine and suppressing the increase in stress blood pressure.

Administration of cilnidipine has been shown to present an antisympathetic profile in vitro and in vivo. It decreases blood pressure safely and effectively without excessive blood pressure reduction or tachycardia.

Nebivolol is a β-adrenergic receptor blocking agent. Nebivolol is a racemate of two enantiomers, d-Nebivolol and l-Nebivolol. Nebivolol exhibits high selectivity for β1-adrenergic receptors and has vasodilating activity due to a direct action on the endothelium, involving nitric oxide release. It lacks intrinsic sympathomimetic and membrane-stabilising activity.

Nebivolol is a selective beta-1 adrenergic receptor antagonist that decreases vascular resistance, increases stroke volume and cardiac output, and does not negatively affect left ventricular function. It has a long duration of action as effects can be seen 48 hours after stopping the medication and a wide therapeutic window as patients generally take 5-40mg daily. Patients should not abruptly stop taking this medication as this may lead to exacerbation of coronary artery disease. Diabetic patients should monitor their blood glucose levels as beta blockers may mask signs of hypoglycemia.

Uses

Cilnidipine is used for the management of hypertension for end-organ protection. It is reported to be useful in elderly patients and in those with diabetes and albuminuria. Cilnidipine has been increasingly used in patients with chronic kidney disease.

Hypertension is the term used to describe the presence of high blood pressure. The blood pressure is generated by the force of the blood pumped from the heart against the blood vessels. Thus hypertension is caused when there is too much pressure on the blood vessels and this effect can damage the blood vessel

Nebivolol is used for the treatment of essential hypertension and adjunct in stable mild to moderate heart failure in patients over 70 years.

Cilnipres N is also used to associated treatment for these conditions: High Blood Pressure (Hypertension)High Blood Pressure (Hypertension)

How Cilnipres N works

Nebivolol is a highly selective beta-1 adrenergic receptor antagonist with weak beta-2 adrenergic receptor antagonist activity. Blocking beta-1 adrenergic receptors by d-nebivolol leads to decreased resting heart rate, exercise heart rate, myocardial contracility, systolic blood pressure, and diastolic blood pressure. The selectivity of d-nebivolol limits the magnitude of beta blocker adverse effects in the airways or relating to insulin sensitivity. Nebivolol also inhibits aldosterone, and beta-1 antagonism in the juxtaglomerular apparatus also inhibits the release of renin. Decreased aldosterone leads to decreased blood volume, and decreased renin leads to reduced vasoconstriction. l-nebivolol is responsible for beta-3 adrenergic receptor agonist activity that stimulates endothelial nitric oxide synthase, increasing nitric oxide levels; leading to vasodilation, decreased peripheral vascular resistance, increased stroke volume, ejection fraction, and cardiac output. The vasodilation, reduced oxidative stress, and reduced platelet volume and aggregation of nebivolol may lead to benefits in heart failure patients.

Dosage

Cilnipres N dosage

5-10 mg once daily, increase to 20 mg once daily if necessary.

Adults: 5 mg daily, maximum recommended dose 40 mg once daily.

Renal Impairment: In patients with severe renal impairment the recommended initial dose is 2.5 mg once daily; titrate up slowly if needed.

Hepatic Impairment: In patients with moderate hepatic impairment, the recommended initial dose is 2.5 mg once daily; titrate up slowly if needed.

Geriatric Patients: It is not necessary to adjust the dose in the elderly.

Pediatric Use: Safety and effectiveness of Nebivolol in pediatric patients have not been established.

Side Effects

Dizziness; flushing; headache; hypotension; peripheral oedema; tachycardia; palpitations; GI disturbances; increased micturition frequency; lethargy; eye pain; depression; ischaemic chest pain; cerebral or myocardial ischaemia; transient blindness; rashes; fever; abnormal liver function; gingival hyperplasia; myalgia; tremor; impotence.

The most common side effects are headache, nausea and bradycardia.

Toxicity

The percentage of reports of cilnidipine that express drug toxicity reported as side effects are 5.26%.

Patients experiencing an overdose may present with bradycardia, hypotension, cardiac failure, dizziness, hypoglycemia, fatigue, vomiting, bronchospasm and heart block. Treat overdose with general supportive measures including intravenous atropine for bradycardia, vasopressors and intravenous fluids for hypotension, isoproterenol infusion for heart block, digitalis glycosides and diuretics for congestive heart failure, bronchodilators for bronchospasm, and intravenous glucose for hypoglycemia.

Precaution

Hypotension, poor cardiac reserve, heart failure. Sudden withdrawal may exacerbate angina. Discontinue in patients who experience ischemic pain following administration. Pregnancy, lactation.

Patients with inadequate cardiac function, well-compensated heart failure, myasthenia gravis. Patients undergoing major surgery involving general anaesth. May mask signs and symptoms of hypoglycaemia and hyperthyroidism. Abrupt withdrawal may exacerbate angina symptoms and/or precipitate MI and ventricular arrhythmias in patients with coronary artery disease. Pregnancy and lactation.

Interaction

Other antihypertensives; aldesleukin; antipsychotics that cause hypotension; may modify insulin and glucose responses; quinidine; carbamazepine; phenytoin; rifampicin; cimetidine; erythromycin.

Use caution when Nebivolol is co-administered with CYP2D6 inhibitors (quinidine, propafenone, fluoxetine, paroxetine, etc.), Do not use Nebivolol with other β-blockers, both digitalis glycosides and β-blockers slow atrioventricular conduction and decrease heart rate. Concomitant use can increase the risk of bradycardia, Nebivolol can exacerbate the effects of myocardial depressants or inhibitors of AV conduction, such as certain calcium antagonists (verapamil and diltiazem), or antiarrhythmic agents, such as disopyramide.

Volume of Distribution

Drugs on the group of dihydropyridines such as cilnidipine tend to have a large volume of distribution.

For a 20mg dose, d-nebivolol has an apparent volume of distribution of 10,290.81±3911.72L, l-nebivolol has an apparent volume of distribution of 8,066.66±4,055.50L, and both enantiomers together have a volume of distribution of 10,423.42±6796.50L.

Elimination Route

Cilnidipine presents a very rapid absorption with a maximum peaked concentration after 2 hours. Its distribution tends to be higher in the liver as well as in kidneys, plasma and other tissues. Cilnidipine does not present a high accumulation in the tissue after repeated oral administration.

Cilnidipine is reported to present very low bioavailability determined to be approximately 13%. This low bioavailability is suggested to be due to its low aqueous solubility and high permeability. Hence, efforts have been made in order to find an innovative formulation that can significantly improve the bioavailability of this drug. One of these formulations corresponds to the generation of polymeric nanoparticles which enhance the bioavailability by 2.5-3-fold.
