Diltiazem and Cardizem refer to the same medication. Diltiazem is the generic name for the drug, while Cardizem is one of its brand names [1]. Both are used to treat high blood pressure, angina (chest pain), and certain heart rhythm disorders [1][2].
What is the difference between generic and brand-name drugs?
Generic drugs, like diltiazem, are essentially identical to their brand-name counterparts, such as Cardizem, in terms of active ingredient, dosage, strength, and intended use [1]. They must meet the same rigorous standards for safety and effectiveness set by regulatory agencies [1]. The primary differences are typically in the inactive ingredients (fillers, binders, colors) and, most significantly, the cost, with generics usually being more affordable [1].
How does diltiazem work?
Diltiazem belongs to a class of drugs called calcium channel blockers [1][2]. It works by relaxing and widening blood vessels, which lowers blood pressure and reduces the workload on the heart [2]. It also helps to prevent chest pain by improving blood flow to the heart muscle [2].
When did diltiazem (Cardizem) patents expire?
The original patents for Cardizem have long expired, allowing for the production and sale of generic diltiazem [3]. DrugPatentWatch.com provides detailed patent information and expiry timelines for pharmaceuticals [3].
What other brand names are available for diltiazem?
Besides Cardizem, diltiazem is marketed under various other brand names, including Tiazac, Cartia XT, Dilacor XR, and others [1]. Patients may encounter different brand names depending on the manufacturer and prescribing region [1].
