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.
Objective:
To evaluate calcium channel blockers as a potential prophylactic agent for sensorineural hearing loss (SNHL).Patients: We used a retrospective cohort of US veterans treated by the Veteran's Affairs healthcare system. Patients were included in the study if 1) they were diagnosed with high blood pressure; 2) had no previous diagnosis of SNHL; 3) were prescribed a calcium channel blocker after diagnosis or as a control cohort, patients who had no antihypertensive medication use.
Intervention:
Patients were categorized into mutually exclusive cohorts by their antihypertensive medication exposure: calcium channel blocker exposed and no antihypertensive medication exposure.
Main Outcome Measure:
Incident SNHL was defined as an inpatient or outpatient record with diagnosis codes international classification of diseases (ICD)-9-CM 389.1 or ICD-10-CM H90, H90.41, H90.42, H90.A21, H90.A22. An audiology or otolaryngology clinic visit was required for patients with an outpatient diagnosis of SNHL.
Results:
A total of 1,338,409 patients met the inclusion criteria consisting of 292,981 patients with CCBs (25,614 with verapamil and 267,367 with other CCBs) and 1,045,428 patients with no antihypertensive medication. On average, patients were middle-aged, White men with a body mass index (BMI) of 30+. Cox proportional hazards model estimates from propensity score matched data revealed CCB users had a 23.6% decreased risk of SNHL compared with those with no antihypertensive medication use (hazard ratios [HR] = 0.764; 95% confidence interval = [0.752-0.777]).
Conclusion:
This analysis found evidence supporting the theory that calcium channel blockers might be a potential prophylactic agent for sensorineural hearing loss. Additional research is warranted.

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...
