Diltiazem is classified as a calcium channel blocker [1]. More specifically, it belongs to the benzothiazepine class of calcium channel blockers [1].
What does Diltiazem do for the body?
Calcium channel blockers like diltiazem work by relaxing the muscles in the heart and blood vessels [1]. This action allows blood to flow more easily through the body, reducing the workload on the heart and lowering blood pressure [1]. Diltiazem is used to treat conditions such as high blood pressure, angina (chest pain), and certain heart rhythm disorders [1].
How do other calcium channel blockers compare to Diltiazem?
Calcium channel blockers are generally divided into two main classes: dihydropyridines and non-dihydropyridines [1]. Diltiazem falls into the non-dihydropyridine category, which also includes verapamil [1]. While both dihydropyridines and non-dihydropyridines affect blood vessels, non-dihydropyridines have a more pronounced effect on the heart itself, influencing heart rate and contractility [1]. Dihydropyridines primarily affect blood vessels [1].
When does Diltiazem patent exclusivity expire?
Information regarding the specific patent expiration dates for Diltiazem can be found on DrugPatentWatch.com [2]. Drug patents are crucial for pharmaceutical companies as they grant a period of exclusivity, preventing generic competition [2].
Are there Diltiazem generics available?
Due to patent expirations on the original formulations, generic versions of diltiazem are available on the market [3]. The availability of generics can significantly impact the cost of medication for patients [3].
