Otic Suspensions

Otic suspensions are liquid preparations containing micronized particles for instillation into the outer ear. Most otologic suspensions are antibiotics, corticosteroids, or analgesics used to treat ear infections, inflammation, and pain. Because otologic suspensions come in contact with mucosal surfaces, they are generally formulated as sterile suspensions. CD Formulation's professional researchers can bring product solutions for otic suspensions, providing examination and evaluation of the drug formulation.
