Amlodipine and Felodipine are both classified as calcium channel blockers, which are medications that inhibit calcium ions from entering vascular smooth muscle and cardiac muscle cells. By doing so, these medications promote vasodilation, decrease peripheral resistance, and ultimately lower blood pressure. This mechanism is particularly beneficial in managing hypertension and angina.

Amlodipine is commonly prescribed because of its long duration of action and is often used in combination with other antihypertensive agents. Felodipine, similarly, effectively reduces blood pressure while also helping to control symptoms of angina.

On the other hand, Metoprolol, which is mentioned in the options, is a beta-blocker, not a calcium channel blocker. It works by blocking the effects of adrenaline on beta-adrenergic receptors, leading to a decrease in heart rate and blood pressure.

Therefore, the option that correctly identifies a calcium channel blocker is indeed the combination of Amlodipine and Felodipine.
