Medication

Medication Summary

The goal of pharmacotherapy is to reduce morbidity and to prevent complications.

Next:

Ophthalmics, Other

Class Summary

May reduce inflammation in cornea by creating an osmotic gradient across an intact blood barrier.

Sodium chloride hypertonic, ophthalmic (Muro 128 5%, Altachlore 5%)

For osmotic pressure control and water distribution.

Antibiotics

Class Summary

Empiric antimicrobial therapy must be comprehensive, covering all likely pathogens in the context of the clinical setting.

Trimethoprim/polymyxin B ophthalmic (Polytrim Ophthalmic Solution)

Used for ocular infections involving cornea or conjunctiva resulting from strains of microorganisms susceptible to this antibiotic combination.

Polymyxin B ophthalmic

Polymyxin B is used for ocular infection of the cornea or conjunctiva caused by susceptible microorganisms.

Polymyxin B/bacitracin ophthalmic (Ak-Poly-Bac, Polycin)

Bacitracin prevents transfer of mucopeptides into the growing cell wall, which causes inhibition of bacterial cell wall synthesis. Polymyxin B damages bacterial cytoplasmic membrane and alters permeability, causing intracellular constituents to leak.

Azithromycin ophthalmic (AzaSite)

This ophthalmic macrolide antibiotic is indicated for bacterial conjunctivitis caused by susceptible strains of microorganisms and for prevention of corneal and conjunctival infections.

Corticosteroids

Class Summary

These have anti-inflammatory properties and cause profound and varied metabolic effects. Corticosteroids modify the body's immune response to diverse stimuli.

Prednisolone acetate (Pred Forte, Omonipred, Pred Mild)

Treats acute inflammations following eye surgery or other types of insults to the eye.

Decreases inflammation by suppressing migration of polymorphonuclear leukocytes and reversing increased capillary permeability.

Previous
Next:

Alpha 2-adrenergic agonists

Class Summary

These can decrease intraocular pressure by decreasing aqueous production.

Brimonidine (Alphagan P)

Selective alpha 2-receptor that reduces aqueous humor formation and increases uveoscleral outflow.

Previous
Next:

Beta-adrenergic blockers

Class Summary

These agents reduce elevated and normal intraocular pressure, with or without glaucoma.

Timolol ophthalmic (Timoptic, Istalol, Betimol)

These may reduce elevated and normal IOP, with or without glaucoma, by reducing production of aqueous humor or by outflow.
