Amlodipine Besylate Overview
Amlodipine (Norvasc) is a long-acting dihydropyridine calcium channel blocker (CCB) used to treat high blood pressure (hypertension), chronic stable angina, vasospastic (Prinzmetal's) angina, and coronary artery disease. It is one of the most widely prescribed medications in the United States, known for its once-daily dosing, excellent tolerability, and proven cardiovascular outcomes data from the...

Amlodipine Besylate
Mechanism of Action — L-Type Calcium Channel Blockade
Amlodipine is a dihydropyridine (DHP) calcium channel blocker that selectively inhibits the influx of calcium ions through voltage-gated L-type calcium channels in vascular smooth muscle and cardiac muscle cells.
Step-by-step mechanism:
- L-type calcium channel blockade: Amlodipine binds to the alpha-1 subunit of L-type (long-lasting) voltage-gated calcium channels in vascular smooth muscle cells. This binding is highly select…
Valsartan
Angiotensin II is formed from angiotensin I in a reaction catalyzed by angiotensin-converting enzyme (ACE, kininase II). Angiotensin II is the principal pressor agent of the renin-angiotensin system, with effects that include vasoconstriction, stimulation of synthesis and release of aldosterone, cardiac stimulation, and renal reabsorption of sodium. Valsartan blocks the vasoconstrictor and aldosterone-secreting effects of angiotensin II by selectively blocking the bindin…
Approved Uses (Indications)
Amlodipine Besylate
FDA-Approved Indications:
Hypertension (adults and pediatric patients ≥6 years):
- Treatment of hypertension to reduce blood pressure and lower the risk of cardiovascular events
- Can be used as monotherapy or in combination with other antihypertensives (e.g., ACE inhibitors, ARBs, thiazides)
- Pediatric use: approved for children ≥6 years; dose 2.5–5 mg once daily
Coronary Artery Disease (CAD):
- Chronic stable angina: Reduces frequency of angina episodes and nitroglycerin use
- Vasospastic angina (Prinzmetal's or variant angina): Blocks coronary artery spasm; confirmed …
Valsartan
Valsartan is an angiotensin II receptor blocker (ARB) indicated for: Hypertension in adults and children six years and older, to lower blood pressure. Lowering blood pressure reduces the risk of fatal and nonfatal cardiovascular events, primarily strokes and myocardial infarctions Heart failure (NYHA class II-IV); Valsartan oral solution significantly reduces hospitalization for heart failure in patients who are unable to swallow valsartan tablets Stable left ventricular failure or left ventricular dysfunction following myocardial infarction; Valsartan oral so…

Cost Comparison
Amlodipine Besylate
$4–$15/month
**Cost & Savings:** Amlodipine is available as an inexpensive generic medication at virtually all pharmacies in the United States. - **Generic amlodipine (5 mg or 10 mg, 30 tablets):** $4–$15/month at most major pharmacy chains (Walmart, Kroger, Costco) and with GoodRx coupons - **Norvasc (brand):** $150–$300+/month; rarely necessary given equivalent generic availability - **Katerzia (oral suspension, 1 mg/mL):** $200–$400/month; used for patients who cannot swallow tablets - **Norliqva (oral suspension, 1 mg/mL):** $200–$400/month; alternative oral suspension **Savings tips:** - Use GoodRx or RxGo to compare prices at local pharmacies — generic amlodipine is often $4–$9/month - Walmart, Kroger, and Costco frequently offer generic amlodipine for $4/month on their discount programs - Mark Cuban's Cost Plus Drugs (costplusdrugs.com) offers amlodipine 5 mg (90 tablets) for approximately $5 - Most insurance plans (including Medicare Part D) cover generic amlodipine at Tier 1 (lowest copay)
Valsartan
$10–$40/month
Since Valsartan is available as a generic, significant savings can be found using discount cards like GoodRx or by checking prices at different pharmacies. Manufacturer coupons are generally not available for generic medications.
Drug Interaction: Moderate
The combination of valsartan and amlodipine can lead to an additive hypotensive effect, potentially causing symptomatic hypotension, especially in patients who are volume-depleted or on other antihypertensive medications. While often used together for synergistic blood pressure reduction, close monitoring is warranted.
Mechanism: Valsartan, an angiotensin receptor blocker (ARB), and amlodipine, a dihydropyridine calcium channel blocker (CCB), both lower blood pressure through different mechanisms. Their concurrent use results in an additive pharmacodynamic effect on blood pressure.
