'''Bromfenac''' is a nonsteroidal anti-inflammatory drug (NSAID) with analgesic and anti-inflammatory properties. It is primarily used in ophthalmology to treat postoperative inflammation and reduce pain in patients who have undergone cataract surgery. Bromfenac works by inhibiting the action of cyclooxygenase (COX) enzymes, which are involved in the synthesis of prostaglandins, substances that mediate inflammation and pain.

Bromfenac is a potent inhibitor of the COX enzymes, with a slightly higher selectivity for COX-2 over COX-1. The inhibition of these enzymes leads to a decrease in the production of prostaglandins, which are key mediators of inflammation and pain. By reducing the levels of prostaglandins, bromfenac effectively reduces inflammation and alleviates pain.

The primary indication for bromfenac is the treatment of postoperative inflammation and pain in patients who have undergone cataract surgery. It is administered as an ophthalmic solution. Bromfenac may also be used for other conditions as determined by a healthcare provider.


== Dosage and Administration ==
==Pharmacology==
Bromfenac is available as an ophthalmic solution, typically in a concentration of 0.07% or 0.09%. The recommended dosage for the treatment of postoperative inflammation and pain following cataract surgery is one drop in the affected eye(s) twice daily, beginning 24 hours after surgery and continuing for the first 14 days postoperatively.

Bromfenac is rapidly absorbed through the cornea and reaches peak concentrations in the aqueous humor. It is metabolized in the liver and excreted primarily in the urine.

Bromfenac is an effective NSAID for the treatment of postoperative inflammation and pain following cataract surgery. Its use should be guided by a healthcare provider, with consideration given to potential side effects, contraindications, and drug interactions.

Nonsteroidal anti-inflammatory drug


Bromfenac chemical structure

Bromfenac is a nonsteroidal anti-inflammatory drug (NSAID) used primarily in the treatment of ocular inflammation and pain following cataract surgery. It is available in the form of an ophthalmic solution and is known for its ability to inhibit the cyclooxygenase (COX) enzymes, which play a key role in the inflammatory process.

Pharmacology[edit]

Bromfenac works by inhibiting the cyclooxygenase enzymes, specifically COX-1 and COX-2, which are involved in the conversion of arachidonic acid to prostaglandins. Prostaglandins are mediators of inflammation, and their inhibition leads to reduced inflammation and pain. Bromfenac is particularly effective in reducing ocular inflammation due to its ability to penetrate ocular tissues efficiently.

Medical uses[edit]

Bromfenac is primarily used in the management of postoperative inflammation and reduction of ocular pain in patients who have undergone cataract surgery. It is administered as an eye drop, typically once or twice daily, depending on the formulation and the specific needs of the patient.

Side effects[edit]

Common side effects of bromfenac include mild to moderate eye irritation, conjunctival hyperemia, and eye pain. Serious side effects are rare but can include corneal thinning, corneal erosion, and delayed healing. Patients are advised to report any unusual symptoms to their healthcare provider.

Chemistry[edit]

Bromfenac cyclic amide structure

Bromfenac is chemically known as 2-amino-3-(4-bromobenzoyl)phenylacetic acid. It is a derivative of amfenac, with a bromine atom added to enhance its anti-inflammatory properties. The presence of the bromine atom increases the lipophilicity of the molecule, allowing for better penetration into ocular tissues.

Comparison with Amfenac[edit]

Comparison of Bromfenac and Amfenac

Bromfenac is closely related to amfenac, another NSAID used in ophthalmology. The primary difference between the two is the presence of a bromine atom in bromfenac, which enhances its potency and duration of action compared to amfenac. This modification allows bromfenac to be used at lower concentrations while maintaining efficacy.
