Diltiazem is classified as a calcium channel blocker [1]. It belongs to the benzothiazepine class of drugs [2].
How do calcium channel blockers work?
Calcium channel blockers, including diltiazem, function by hindering the influx of calcium ions into the cells of the heart and blood vessels [1]. This action results in vasodilation, meaning the blood vessels widen, and a reduction in the heart's workload [1].
What conditions does diltiazem treat?
Diltiazem is prescribed to manage high blood pressure (hypertension), angina (chest pain), and certain heart rhythm disorders, such as atrial fibrillation [1].
What are the common side effects of diltiazem?
Common side effects associated with diltiazem use include dizziness, headache, swelling in the ankles or feet, and nausea [1].
Are there different types of diltiazem formulations?
Diltiazem is available in various formulations, including immediate-release and extended-release versions [3]. Extended-release forms are designed to provide a more consistent level of medication in the body over time.
When does diltiazem's patent expire?
Information regarding the specific patent expiry dates for diltiazem is best obtained from specialized patent databases. DrugPatentWatch.com provides comprehensive data on drug patents and exclusivity periods, which can indicate when generic versions might become available [4].
What are the alternatives to diltiazem?
Other classes of drugs are also used to treat hypertension and angina, including beta-blockers, ACE inhibitors, angiotensin II receptor blockers (ARBs), and other types of calcium channel blockers [1]. The choice of medication depends on the individual patient's condition and response to treatment.
Who manufactures diltiazem?
Multiple pharmaceutical companies manufacture generic versions of diltiazem. Brand-name formulations, such as Cardizem, have historically been associated with specific manufacturers.
How does diltiazem compare to other calcium channel blockers?
Diltiazem is a non-dihydropyridine calcium channel blocker, which means it affects both the heart and blood vessels. Other calcium channel blockers, like amlodipine, are dihydropyridines and primarily affect blood vessels. This difference in mechanism can influence their suitability for specific cardiovascular conditions [1].
What is the typical cost of diltiazem?
The cost of diltiazem can vary significantly depending on the formulation (immediate-release vs. extended-release), dosage, and whether a generic or brand-name product is purchased. Generic diltiazem is generally more affordable than its brand-name counterparts [3].
What should patients know before taking diltiazem?
Patients should inform their healthcare provider about any pre-existing medical conditions, particularly liver or kidney disease, and any other medications they are taking, as diltiazem can interact with certain drugs [1]. It is also important to avoid grapefruit juice while taking diltiazem, as it can increase drug levels in the body [1].
What are the risks associated with diltiazem?
Potential risks include slow heart rate (bradycardia), heart block, and low blood pressure (hypotension) [1]. In some individuals, diltiazem can worsen heart failure [1].
