Insights

Calcium channel blockers may help prevent sensorineural hearing loss (SNHL). This study found CCB users had a 23.6% decreased risk of SNHL compared to non-users, suggesting a potential prophylactic role.

Area of Science:

  • Cardiology
  • Otolaryngology
  • Pharmacology

Background:

  • Sensorineural hearing loss (SNHL) is a significant health concern.
  • Hypertension is a common comorbidity associated with SNHL.
  • Calcium channel blockers (CCBs) are widely used antihypertensive medications.

Purpose of the Study:

  • To investigate the potential of calcium channel blockers (CCBs) as a prophylactic agent for sensorineural hearing loss (SNHL).

Main Methods:

  • Retrospective cohort study of US veterans within the Veteran's Affairs healthcare system.
  • Inclusion criteria: diagnosed hypertension, no prior SNHL diagnosis, and either prescribed CCBs or no antihypertensive medication.
  • Propensity score matching was used to compare outcomes between CCB users and a control group.

Main Results:

  • A total of 1,338,409 patients were analyzed, with 292,981 in the CCB group and 1,045,428 in the control group.
  • CCB users exhibited a 23.6% reduced risk of developing SNHL compared to individuals not using antihypertensive medications (HR = 0.764, 95% CI [0.752-0.777]).

Conclusions:

  • Findings suggest that calcium channel blockers may serve as a potential prophylactic agent against sensorineural hearing loss.
  • Further research is recommended to confirm these findings and explore the underlying mechanisms.

Antiarrhythmic Drugs: Class I Agents as Sodium Channel Blockers

Class I antiarrhythmic drugs are used to treat various types of arrhythmias or irregular heart rhythms. These drugs block the sodium (Na+) channels in the cardiac cells, thereby affecting the movement of electrical impulses across the heart. Class I antiarrhythmic drugs are divided into three subgroups: Class IA, Class IB, and Class IC, each with distinct mechanisms of action and effects on the heart.
Class 1A Antiarrhythmic Drugs: These drugs work by moderately blocking sodium channels,...

Antiarrhythmic Drugs: Class IV Agents as Calcium Channel Blockers

Class IV antiarrhythmic drugs, such as verapamil and diltiazem, block calcium channels. They primarily affect the heart, slowing the conduction in calcium-dependent tissues like the SA and AV nodes. These drugs manage reentrant supraventricular tachycardia (SVT) and reduce ventricular rate in atrial flutter/fibrillation.
Verapamil, a calcium channel blocker, inhibits calcium movement across myocardial cell membranes and vascular smooth muscle. This results in the dilation of coronary and...

Antianginal Drugs: Calcium Channel Blockers and Ranolazine

Angina pectoris, a primary symptom of ischemic heart disease, requires careful pharmacological interventions. In this context, calcium channel blockers (CCBs) and ranolazine have emerged as crucial pharmacotherapeutic agents, providing deep insights into the complexities of angina management.
CCBs, a diverse class that includes dihydropyridines (nifedipine) and diphenylalkylamines (verapamil and diltiazem), exert their effect by blocking calcium channels in cardiac and smooth muscle cells. This...

Antihypertensive Drugs: Action of Calcium Channel Blockers01:18

Antihypertensive Drugs: Action of Calcium Channel Blockers

Calcium ions are essential to contract smooth muscle cells in blood vessels. They enter these cells through voltage-dependent calcium channels, specifically L-type calcium channels in the cell membrane. These L-type calcium channels are integral to the excitation-contraction coupling process in smooth muscle. When a stimulus is received by smooth muscle cells, their membrane depolarizes. This alteration in membrane potential instigates the opening of L-type calcium channels. As a result,...

Antiepileptic Drugs: Calcium Channel Blockers01:17

Antiepileptic Drugs: Calcium Channel Blockers

Calcium channel blockers, a class of antiepileptic drugs, regulate the flow of calcium ions within neurons.
Calcium channel blockers exert their antiepileptic effects by targeting T-type calcium channels, which are integral to transmitting nerve signals in the central nervous system. These channels allow the passage of calcium ions, which are vital for neuronal communication. By inhibiting T-type calcium channels, calcium channel blockers effectively reduce the release of neurotransmitters and...

Antiarrhythmic Drugs: Class III Agents as Potassium Channel Blockers01:12

Antiarrhythmic Drugs: Class III Agents as Potassium Channel Blockers

Class III antiarrhythmic drugs are a group of medications that can prolong action potentials in the heart. They achieve this by blocking potassium channels or enhancing inward currents from sodium channels. However, these drugs have a unique property of "reverse use-dependence," which is most pronounced at slower heart rates and can lead to torsades de pointes—a specific type of arrhythmia. However, it is essential to note that excessive QT interval prolongation—a measure of...
