Tiapamil
chemical compound

Tiapamil (INN; also known as dimeditiapramine) is a calcium antagonist or calcium channel blocker. It is an experimental drug that has never been marketed.
Tiapamil has been described as an antianginal agent. It exhibits properties of anti-arrhythmic medications. These are medications that are used to treat unusually fast or irregular heartbeats. Examples of arrhytmthic conditions include atrial fibrillation, atrial flutter, and super-ventricular tachycardia. Upon research, the drug shows promising effects on treatment of these condition. Research seeks to create a treatment with tiapamil in order to mitigate the side effects of the more commonly prescribed calcium antagonist and anti-hypertensive verapamil. The two drugs have similar properties; however, tiapamil appears to treat arrhythmic conditions without many of the hypotensive, negative inotropic, and negative chronotropic side effects. Tiapamil is a calcium channel blocker that acts on the slow calcium channels.

Why this record matters
“Tiapamil” is worth following because a concise public description often conceals a longer documentary argument. Here, Tiapamil, chemical and compound provides the most credible route into that argument.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Aug 21, 2026. The linked authority identifier is Q5277228. None of the 0 selected statements returned an explicit reference.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
