Summary
Local drug therapy offers new hope for inner ear hearing loss, including sudden sensorineural hearing loss and Menière's disease. Understanding drug delivery (LADME) is key to developing effective treatments for hearing restoration.
Area of Science:
- Otolaryngology
- Pharmacology
- Regenerative Medicine
Context:
- Inner ear hearing loss encompasses conditions like sudden sensorineural hearing loss, Menière's disease, and ototoxicity.
- Local drug delivery presents a promising therapeutic avenue for various inner ear disorders.
- Current research explores diverse pharmacological agents for inner ear treatment.
Purpose:
- To review the indications for local drug therapy in inner ear hearing loss.
- To discuss current and emerging drugs used in local inner ear treatments.
- To highlight the application of the LADME principle for optimizing inner ear pharmacotherapy.
Summary:
- Indications for local drug therapy include sudden sensorineural hearing loss, Menière's disease, autoimmune hearing loss, ototoxicity, acoustic trauma, and cochlear implant enhancement.
- Investigational drugs include glucocorticoids, growth factors, apoptosis inhibitors, antioxidants, TNF-α inhibitors, and antibodies.
- The LADME (liberation, absorption, distribution, metabolism, elimination) principle is crucial for understanding pharmacokinetics in local inner ear drug delivery.
Impact:
- Facilitates a deeper understanding of drug behavior within the inner ear.
- Aims to guide the rational development of effective pharmacotherapies for hearing loss.
- Supports the advancement of local drug delivery strategies, including intratympanic and intralabyrinthine applications.

Auditory sensation, commonly called hearing, involves the transformation of sonic waves into neural impulses facilitated by the structures of the auditory organ. The prominent, flesh-like structure on the side of the head, called the auricle, directs sound waves towards the auditory canal. The auricle is often mislabeled as the pinna, a term more aligned with mobile structures like a feline's external ear. The auditory canal penetrates the cranium via the external auditory meatus of the...

Drug delivery methods like oral inhalation, nasal sprays, transdermal patches, eye drops, intravitreal injection, and rectal administration provide localized effects with reduced toxicity.
Oral inhalation and nasal sprays swiftly transfer drugs across the respiratory epithelium's mucosal layer. Inhaled glucocorticoids and bronchodilators directly target lung conditions such as asthma, while fluticasone nasal spray mitigates allergic rhinitis.

The cochlea is a coiled structure in the inner ear that contains hair cells—the sensory receptors of the auditory system. Sound waves are transmitted to the cochlea by small bones attached to the eardrum called the ossicles, which vibrate the oval window that leads to the inner ear. This causes fluid in the chambers of the cochlea to move, vibrating the basilar membrane.

When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.
