Leukotriene-Receptor Antagonists (LTRAs) seem like to become a standard of inhaled glucocorticoids for people who need asthma treatment, but other also agree that drugs also helps the symptom reduction since they work as monotherapy for asthma patients.

LTRA is mostly recommended for asthma patients since it works as first-line treatment to control the asthma on patients with mild persistent disease. Based on the clinical trials under serious control, TRLAs are clearly effective to reduce symptoms.

Particular study conducted to evaluate LTRAs effectiveness that involved both LTRA and inhaled glucocorticoid as first-line therapy.

The ear is divided into the outer, middle, and inner parts. The outer ear consists of the auricle and the auditory canal. The middle ear, a small chamber lying within the temporal bone and separated from the outer ear by the eardrum (tympanic membrane), houses the ossicles (three tiny bones bearing the names malleus, incus, and stapes) and communicates with the upper throat via the eustachian tube.

The inner ear consists of the outer osseous labyrinth enclosing the inner membranous labyrinth, whose parts are the cochle, semicircular canals, utricle, and saccule. A watery fluid, the perilymph, fills the space between the osseous and membranous labyrinths, and another watery fluid, the endolymph, fills the membranous labyrinth. The organ of Corti, the actual receptor of sound, is situated within the cochlea.
