CLINICAL PHARMACOLOGY

Antipyrine and Benzocaine Otic Solution combines the hygroscopic property of anhydrous glycerin with the analgesic action of antipyrine and benzocaine to relieve pressure, reduce inflammation and congestion, and to alleviate pain and discomfort in acute otitis media.

Antipyrine and Benzocaine Otic Solution does not blanch the tympanic membrane or mask the landmarks and, therefore, does not distort the otoscopic picture.

ANTIPYRINE AND BENZOCAINE INDICATIONS AND USAGE

Acute Otitis media of various etiologies

• -prompt relief of pain and reduction of inflammation in the congestive and serous stages.
• -adjuvant therapy during systemic antibiotic administration for resolution of the infection.

Because of the close anatomical relationship of the eustachian tube to the nasal cavity, otitis media is a frequent problem, especially in children in whom the tube is shorter, wider, and more horizontal than in adults.

Removal of Cerumen

• -facilitates the removal of excessive or impacted cerumen.

ANTIPYRINE AND BENZOCAINE CONTRAINDICATIONS

The product is contraindicated in any person with hypersensitivity to any of the components or substances related to them. This product is contraindicated in the presence of spontaneous perforation of the tympanic membrane or discharge.
