  • Verapamil is only moderately effective as an antianginal agent
  • Annals of emergency
  • Interventions: Patients received up to two intravenous boluses of either diltiazem or verapamil, followed by an 8-hour continuous infusion if a therapeutic response was achieved (phase I)

    2 Both verapamil and diltiazem have similar mechanisms of action, contraindications, relative precautions, and proven comparative efficacy

    Snapshot A 56-year-old man recently had a myocardial infarction

    Calcium channel blockers work by blocking the initial calcium influx into myocytes and vascular smooth muscle cells, preventing the cascade of events detailed above

    Verapamil and diltiazem are used interchangeably for rate control in A-fib with RVR

    5 vs 219

    The Food and Drug Administration (FDA) approved indications for verapamil include angina (chronic stable, vasospastic or Prinzmetal variant), unstable angina (crescendo, preinfarction), hypertension as add-on therapy, paroxysmal supraventricular tachycardia (PSVT) prophylaxis, and supraventricular tachycardia (SVT)

    Additionally, while verapamil and diltiazem both have negative chronotropic effects -- verapamil has more negative inotropy, which is a no-no in decompensated heart failure, though in my opinion, neither of these nodal agents should be used in acute decompensated heart failure

    Less commonly, nausea, vomiting, dizziness, and fatigue have also been reported

    At 2 minutes after the initial bolus dose, the mean ventricular rate decreased to 100 ± 13 beats/minute in the diltiazem group compared with 114 ± 17 beats/minute in Rats were randomized into three groups: a control group, a verapamil-treated group, and a diltiazem-treated group, each consisting of five animals

    The contraindications and adverse effects of non-dihydropyridine (DHP) CCBs (diltiazem and verapamil) are quite different from DHP CCBs (amlodipine, felodipine, nifedipine)

    Verapamil and diltiazem are reported to increase AUC and Cmax for DOACS by 196% and 40%, and 250% and 31%, respectively

    At 1 h after receiving the initial rate control drug, there was no statistical difference between diltiazem, metoprolol, and verapamil in achieving ventricular rate less than 100 bpm (15

    "Verapamil is more constipating and is a stronger negative inotrope so more caution required in the context of concern for heart failure (e

    Verapamil belongs to the Phenylalkylamines class of calcium channel blockers and Diltiazem belongs to a class called the Benzothiazepines

    Diltiazem is used alone or together with other medicines to treat angina (severe chest pain) or hypertension (high blood pressure)

    The best rate control in verapamil and digoxin groups was observed after 5

    Conclusion: Administration of verapamil in comparison with digoxin has no difference to There are four main groups of antiarrhythmic medications: class I, sodium-channel blockers; class II, beta-blockers; class III, potassium-channel blockers; class IV, calcium-channel blockers; and miscellaneous antiarrhythmics, or unclassified antiarrhythmics

    45% of reviewers reported a positive effect, while 33% reported a negative effect

    Class 4 antiarrhythmics include the drugs verapamil and diltiazem, and these drugs function primarily by blocking Calcium channels at the heart

    3 Observations from a large-scale registry suggested that in patients with HFpEF and a heart rate of ≥70 beats per minute, high dose beta blocker use was associated with lower all-cause mortality

    However, an initial bolus dose was more common in the diltiazem group as compared with the verapamil group

    Verapamil can help regulate the heart rate and lower blood pressure and is used to treat certain heart conditions

    All CCBs are substrates of CYP3A4, but both diltiazem and verapamil are also inhibitors of 3A4 and have an increased risk of drug interactions

    Vasospastic angina, which was previously referred to as Prinzmetal [ 1] or variant angina, is characterized by episodes of rest angina that promptly respond to short-acting nitrates and are attributable to coronary artery vasospasm

    Only amlodipine significantly reduced the exercise pulmonary Calcium blockers like diltiazem and verapamil can be effective too, it's a bit trial and error, it all depends on what's causing them

    2) Epicutaneous tests have been useful for diagnosis

    stronger inebriant than methanol and ethanol causing mild depression of CNS resulting in seizures and coma

    In 1991, Kaesemeyer et al

    Better control of heart rate (<80 bpm vs 80-100 bpm) was achieved in the verapamil

    Diltiazem has an average rating of 6

    Lower utilization of verapamil compared with diltiazem naturally leads to

    Nifedipine plus diltiazem had a greater antihypertensive effect than

    Characteristics of three different calcium antagonist groups: Most important calcium

    We conducted a population-based, retrospective cohort study of all adults (aged ≥ 66 years) on a DOAC (dabigatran, apixaban, rivaroxaban; n = 295,038) who were newly prescribed amiodarone (n = 4872), verapamil (n = 1284), or diltiazem (n = 14,638), compared with metoprolol or amlodipine, from Ontario, Canada (2009-2016)

    All CCBs are substrates of CYP3A4, but both diltiazem and verapamil are also inhibitors of 3A4 and have an increased risk of drug interactions

    A randomized blind cross-over study with placebo lead-in compared efficacy of calcium antagonists diltiazem and verapamil in 71 patients with stable angina concurrent with arterial hypotension (group 1) and 38 normotensive patients with ischemic heart disease (group 2)

    Overall, 65 patients (89%) in the verapamil group and 66 patients (90%) in the diltiazem group achieved an HR <110 bpm during the infusion (P =

    The heart rate increase for amlodopine differed from verapamil and diltiazem (+19

    In the first treatment period, diltiazem and verapamil improved subjective complaints in 83% and 71% of those who were symptomatic in the baseline Amlodipine has an average rating of 4

    By blocking calcium, calcium channel blockers allow blood vessels to relax and open

    It works by relaxing blood vessels in the body and heart and lowers the heart rate
