    • erythromycin base
  293. antiglaucoma agents

    • timolol (Betimol) , acetazolamide (Diamox)
  294. mydriatics
    • drugs that disrupt parasympathetic nerve supply to the eye or stimulate the sympathetic nervous system, causing the pupil to dilate
    • commonly used to dilate the pupil to treat inflammatory conditions or in preparation for internal examinations of the eye
    • atropine sulfate
  295. ophthalmic decongestants
    • constrict the small arterioles of the eye, decreasing redness and relieving conjunctival congestion
    • otc products that temporarily relieve the itching and minor irritation commonly associated with allergy
    • tetrahydrozoline (Murine, Visine)
  296. ophthalmic moisturizers
    • sooth dry eyes due to environmental irritants and some allergens
    • administered topically and may also be used to facilitate ophthalmoscopic examination in gonioscopy and ophthalmoscopy
    • buffered isotonic solutions (Akwa Tears, moisure eyes)
  297. ear antiemetics
    • treat and prevent nausea, vomiting, dizziness, and vertigo by reducing the sensitivity of the inner ear to motion or inhibiting stimli from reaching the part of the brain that triggers nausea and vomiting
    • meclizine (Antrizine, Bonine, Meni-D)
  298. otic analgesics
    • provide temporary relief from pain and inflammation assoc with otic disorders
    • may be perscribed for otitis media, otitis externa, and swimmer's ear. some are also wax emulsifiers
    • antipyrine and benzocaine (Allergan Ear Drops, A/B Otic)
  299. wax emulsifiers
    • loosen and help remove impacted cerumen (ear wax)
    • carbamide peroxide (Debrox drops, Murine ear drops)
