Diltiazem, sold under the brand name Cardizem among others, is a nondihydropyridine calcium channel blocker medication used to treat high blood pressure, angina, and certain heart arrhythmias. [9] It may also be used in hyperthyroidism if beta blockers cannot be used. [ 9 ]
Modified-release dosage is a mechanism that (in contrast to immediate-release dosage) delivers a drug with a delay after its administration (delayed-release dosage) or for a prolonged period of time (extended-release [ER, XR, XL] dosage) or to a specific target in the body (targeted-release dosage).

Structural formula of diltiazem. Benzothiazepine calcium channel blockers belong to the benzothiazepine class of compounds and are an intermediate class between phenylalkylamine and dihydropyridines in their selectivity for vascular calcium channels. By having both cardiac depressant and vasodilator actions, benzothiazepines are able to reduce ...

1,3-thiazepine 1,4-thiazepine Diltiazem. 1,4-thiazepine is the seven membered ring in the middle. Thiazepines are substituted thiepins, with a nitrogen replacing a carbon in the seven-membered heterocyclic compound. [1] Depending on the location of the nitrogen, one distinguishes 1,3-thiazepine and 1,4-thiazepine. [1]
L-type Calcium Channels contain 5 different subunits, the α1(170–240 kDa), α2(150kDa), δ(17-25 kDa), β(50-78 kDa), and γ(32 kDa) subunits. [8] The α2, δ, and β subunits are non-covalently bonded to the α1 subunit and modulate ion trafficking and biophysical properties of the α1 subunit.
Dihydropyridine calcium channel blockers are derivatives of 1,4-dihydropyridine that are used as L-type calcium channel blockers. [1] They are used in the treatment of hypertension.
