Dosing

Hypertensive disease Starting dose 40/12.5 mg or 20/12.5 mg once daily depending on prior monotherapy; titrate up to 40/25 mg if needed.

Hypertensive disease - Adults The usual initial antihypertensive oral dose of NORVASC is 5 mg once daily, and the maximum dose is 10 mg once daily. Small, fragile, or elderly patients, or patients with hepatic insufficiency may be started on 2.5 mg once daily and this dose may be used when adding NORVASC to other antihypertensive therapy. Adjust dosage according to blood pressure goals. In general, wait 7 to 14 days between titration steps. Titrate more rapidly, however, if clinically warranted, provided the patient is assessed frequently.

Hypertensive disease - Pediatric patients The effective antihypertensive oral dose in pediatric patients ages 6-17 years is 2.5 mg to 5 mg once daily. Doses in excess of 5 mg daily have not been studied in pediatric patients.

Stable angina The recommended dose for chronic stable angina is 5-10 mg once daily, with the lower dose suggested in the elderly and in patients with hepatic insufficiency. Most patients will require 10 mg for adequate effect.

Angina Pectoris, Variant The recommended dose for vasospastic angina is 5-10 mg once daily, with the lower dose suggested in the elderly and in patients with hepatic insufficiency. Most patients will require 10 mg for adequate effect.

Coronary Artery Disease The recommended dose range for patients with coronary artery disease is 5-10 mg once daily. In clinical studies, the majority of patients required 10 mg.

Adverse Reactions

Most common (>2%) Dizziness, upper respiratory infection, hyperuricemia, nausea

Serious Hypotension, impaired renal function, hypersensitivity reactions, electrolyte and metabolic imbalances, acute myopia and secondary angle-closure glaucoma, systemic lupus erythematosus, sprue-like enteropathy

Postmarketing Asthenia, vomiting, hyperkalemia, rhabdomyolysis, alopecia, pruritus

Most common adverse reactions (incidence >1%) The most common adverse reaction to amlodipine is edema which occurred in a dose related manner (up to 10.8% at 10 mg dose vs 0.6% placebo). Other adverse experiences not dose related but reported with an incidence >1.0% are fatigue (4.5%), nausea (2.9%), abdominal pain (1.6%), and somnolence (1.4%).

Dose-related adverse reactions Edema: 1.8% (2.5 mg), 3.0% (5 mg), 10.8% (10 mg) vs 0.6% (placebo). Dizziness: 1.1% (2.5 mg), 3.4% (5 mg), 3.4% (10 mg) vs 1.5% (placebo). Flushing: 0.7% (2.5 mg), 1.4% (5 mg), 2.6% (10 mg) vs 0.0% (placebo). Palpitation: 0.7% (2.5 mg), 1.4% (5 mg), 4.5% (10 mg) vs 0.6% (placebo).

Gender differences For several adverse experiences that appear to be drug and dose related, there was a greater incidence in women than men: Edema (14.6% female vs 5.6% male), Flushing (4.5% female vs 1.5% male), Palpitations (3.3% female vs 1.4% male).

Less common adverse reactions (<1% but >0.1%) Cardiovascular: arrhythmia (including ventricular tachycardia and atrial fibrillation), bradycardia, chest pain, peripheral ischemia, syncope, tachycardia, vasculitis. Central and Peripheral Nervous System: hypoesthesia, neuropathy peripheral, paresthesia, tremor, vertigo. Gastrointestinal: anorexia, constipation, dysphagia, diarrhea, flatulence, pancreatitis, vomiting, gingival hyperplasia. General: allergic reaction, asthenia, back pain, hot flushes, malaise, pain, rigors, weight gain, weight decrease. Musculoskeletal: arthralgia, arthrosis, muscle cramps, myalgia. Psychiatric: sexual dysfunction, insomnia, nervousness, depression, abnormal dreams, anxiety, depersonalization. Respiratory: dyspnea, epistaxis. Skin: angioedema, erythema multiforme, pruritus, rash, rash erythematous, rash maculopapular. Special Senses: abnormal vision, conjunctivitis, diplopia, eye pain, tinnitus. Urinary: micturition frequency, micturition disorder, nocturia. Autonomic: dry mouth, sweating increased. Metabolic: hyperglycemia, thirst. Hemopoietic: leukopenia, purpura, thrombocytopenia.

Postmarketing experience Gynecomastia has been reported infrequently. Jaundice and hepatic enzyme elevations (mostly consistent with cholestasis or hepatitis), in some cases severe enough to require hospitalization, have been reported in association with use of amlodipine. A possible association between extrapyramidal disorder and amlodipine has been reported.

Pharmacology

Olmesartan medoxomil selectively blocks angiotensin II binding to the AT1 receptor in vascular smooth muscle, inhibiting vasoconstriction independent of angiotensin II synthesis pathways; hydrochlorothiazide is a thiazide diuretic that directly increases renal excretion of sodium and chloride, reducing plasma volume to lower blood pressure.

Amlodipine is a dihydropyridine calcium antagonist (calcium ion antagonist or slow-channel blocker) that inhibits the transmembrane influx of calcium ions into vascular smooth muscle and cardiac muscle. Amlodipine binds to both dihydropyridine and nondihydropyridine binding sites. The contractile processes of cardiac muscle and vascular smooth muscle are dependent upon the movement of extracellular calcium ions into these cells through specific ion channels. Amlodipine inhibits calcium ion influx across cell membranes selectively, with a greater effect on vascular smooth muscle cells than on cardiac muscle cells. Amlodipine is a peripheral arterial vasodilator that acts directly on vascular smooth muscle to cause a reduction in peripheral vascular resistance and reduction in blood pressure. In patients with exertional angina, NORVASC reduces the total peripheral resistance (afterload) against which the heart works and reduces the rate pressure product, and thus myocardial oxygen demand, at any given level of exercise. In vasospastic angina, NORVASC blocks constriction and restores blood flow in coronary arteries and arterioles, inhibiting coronary spasm. Following administration of therapeutic doses to hypertensive patients, NORVASC produces vasodilation resulting in a reduction of supine and standing blood pressures. These decreases in blood pressure are not accompanied by a significant change in heart rate or plasma catecholamine levels with chronic dosing. With chronic once daily oral administration, antihypertensive effectiveness is maintained for at least 24 hours. Plasma concentrations correlate with effect in both young and elderly patients.
