Topical corticoste­roids and NSAID drops in treating Macular Edema or CME


Topical corticoste­roids and NSAID drops

Treatments —Medical

Topical non-steroidal anti-inflammatory medications are the most common treatment for ME following cataract sur­gery (See Figure 3). These agents are di­­rected at decreasing intraocular pro­staglandin levels, which have been im­plicated in the path­ogenesis of ME. Dou­ble-masked, randomized, active and placebo-controlled studies including patients un­dergoing cataract surgery have re­ported anti-inflammatory effects from topically applied 1% in­do­meth­a­cin, 0.03% flurbiprofen, 0.5% ketorolac, and 0.1% diclofenac ophthalmic pre­pa­ra­tions.15,16″

Diclofenac 0.1% and ke­to­ro­lac 0.5% ophthalmic solutions, however, are the only topically applied NSAIDs spe­cif­ically approved by the Food and Drug Administration for this in­dication”.

“Therapy combining a topical corticoste­roid and NSAID drops has been found to have greater efficacy in treating ME than either medication alone.16 Al­though not FDA-approved, topical NSAIDs are often used prior to cat­aract surgery to prevent postoperative ME”.

Oral acetazolamide is occasionally used in the treatment of ME secondary to inflammatory conditions and retinitis pig­mentosa, particularly when topical NSAIDs and corticosteroids fail. Several prospective, masked, crossover studies comparing ace­tazolamide and placebo in patients with ME due to a variety of causes. A five-cycle crossover study in 41 patients found a reproducible response, characterized as either partial or complete resolution of ME, in more than half of the patients with inherited or in­flammatory retinal disease, but no re­sponse from those with primary retinal vas­cular diseases”.17

“A 500-mg/day or oral acetazolamide was found to be more ef­fective than 250-mg/day in treating ME in patients with ME secondary to RP.18 This study ob­served improvement in 10 of 12 treated pa­tients”.

Addtionally, Reviewofophthalmology.com article stated:

“Corticosteroids are potent anti-in­flam­matory agents that are used frequently in the treatment of ME. They have multiple mechanisms of action, including stabilization of the blood-retinal barrier and inhibition of pro-inflammatory mediators. Delivery modes in­clude topical, periocular injection, intravitreal injection, and both oral and in­tra­venous administration. While oral and IV corticosteroids certainly reach the­rapeutic levels within the vitreous, they expose patients to the additional risk of systemic complications, and are therefore usually reserved for patients with sight-threatening uveitis in the setting of systemic disease. Topical corticosteroid drops are at the other end of the safety spectrum, but their ability to reach the posterior segment is limited”.

indomethacin

[in″do-meth´ah-sin]
“a nonsteroidal antiinflammatory drug used in the treatment of rheumatoid arthritis, osteoarthritis, ankylosing spondylitis, and various other rheumatic and nonrheumatic inflammatory conditions, dysmenorrhea, and vascular headache. The trihydrated sodium salt is used to induce closure in certain cases of patent ductus arteriosus“.

FDA Box Warning

•” Drug may increase risk of serious cardiovascular thrombotic events, myocardial infarction, and stroke (which can be fatal). Risk may increase with duration of use, and may be greater in patients who have cardiovascular disease or risk factors for it”.

Drug is contraindicated for perioperative pain in setting of coronary artery bypass graft surgery.

• “Drug increases risk of serious GI adverse events, including bleeding, ulcers, and stomach or intestinal perforation, which can be fatal. These events can occur at any time during therapy and without warning. Elderly patients are at greater risk”.

Flurbiprofen

COMMON BRAND(S): Ansaid

GENERIC NAME(S): Flurbiprofen

Diclofenac Ophthalmic Solution Description

Diclofenac Sodium Ophthalmic Solution, 0.1% is a sterile, topical, nonsteroidal, anti-inflammatory product for ophthalmic use. Diclofenac sodium is designated chemically as 2-[(2,6-dichlorophenyl)amino] benzeneacetic acid, monosodium salt, with an empirical formula of C14H10Cl2NO2 Na. The structural formula of diclofenac sodium is:

Pharmacodynamics

“Diclofenac sodium is one of a series of phenylacetic acids that has demonstrated anti-inflammatory and analgesic properties in pharmacological studies. It is thought to inhibit the enzyme cyclooxygenase, which is essential in the biosynthesis of prostaglandins”.

Acetazolamide

COMMON BRAND(S): Diamox

GENERIC NAME(S): Acetazolamide

“This drug is also used with other medications to treat a certain type of eye problem (open-angle glaucoma). Acetazolamide is a “water pill” (diuretic). It decreases the amount of fluid that can build up in the eye. It is also used to decrease a buildup of body fluids (edema) caused by congestive heart failure or certain medications. Acetazolamide can work less well over time, so it is usually used only for a short period.

It has also been used with other medications to treat certain types of seizures (petit mal and unlocalized seizures).

How to use Acetazolamide

If you are taking the tablets, take this medication by mouth, usually 1 to 4 times daily or as directed by your doctor. If you are taking the long-acting capsules, take this medication by mouth, usually 1 or 2 times daily or as directed by your doctor. Swallow the long-acting capsules whole. Do not open, break, or chew the capsules. Doing so can destroy the long action of the drug and may increase side effects.

Acetazolamide may be taken with or without food. Drink plenty of fluids unless otherwise directed by your doctor. Your dosage is based on your medical condition and response to therapy.

Nepafenac Ophthalmic
