The design and screening of drugs to prevent acquired sensorineural hearing loss

Area of Science:

• Ototoxicity and Hearing Loss Prevention
• Pharmacological Interventions for Hearing Protection

Background:

• Sensorineural hearing loss is a widespread issue, significantly impacting patients undergoing cisplatin chemotherapy and those treated with aminoglycoside antibiotics.
• Noise-induced hearing loss is also prevalent, with limited effectiveness of traditional ear protection methods.
• Developing preventative drug therapies for hearing loss would greatly benefit public health.

Purpose of the Study:

• This review examines research on protective agents against hearing loss induced by cisplatin, aminoglycoside antibiotics, and noise.
• It evaluates the efficacy of these agents in animal models and their ongoing clinical trial applications.

Main Methods:

• Review of scientific literature on protective agents for cisplatin-induced ototoxicity.
• Analysis of research on agents preventing aminoglycoside antibiotic-induced hearing loss.
• Examination of studies on preventing noise-induced hearing loss.
• Assessment of animal study data and ongoing clinical trial results.

Main Results:

• Significant research findings on protective agents against cisplatin, aminoglycoside, and noise-induced hearing loss are discussed.
• Efficacy of these agents in animal studies is presented.
• Application and progress of these protective agents in ongoing clinical trials are detailed.

Conclusions:

• Future strategies for preventing sensorineural hearing loss from cisplatin, aminoglycosides, and noise are highlighted.
• Numerous agents are emerging as potential preventatives for drug- and noise-induced hearing loss.
• Novel drug delivery systems aim to target the inner ear, minimizing side effects and interference with primary treatments.
