Diclofenac sodium eye drops
Function and Efficacy
Diclofenac sodium is a non-steroidal anti-inflammatory analgesic derived from phenylacetic acid. Its mechanism of action is to inhibit the activity of cyclooxygenase, thereby blocking the conversion of arachidonic acid to prostaglandins. At the same time, it can also promote the combination of arachidonic acid with triglycerides, reduce the concentration of free arachidonic acid in cells, and indirectly inhibit the synthesis of leukotrienes. Animal experiments have confirmed that prostaglandins are one of the mediators of intraocular inflammation, which can lead to blood-aqueous barrier collapse, vasodilation, increased vascular permeability, leukocyte chemotaxis, non-cholinergic mechanism pupil constriction, etc. Diclofenac sodium is a stronger non-steroidal anti-inflammatory drug. Its inhibitory effect on prostaglandin synthesis is stronger than that of aspirin and indomethacin. Diclofenac sodium eye drops have a strong inhibitory effect on the collapse of the blood-aqueous barrier caused by mechanical, chemical, biological and other stimuli. Clinical studies have shown that 0.1% diclofenac sodium can reduce flare and cell count in the anterior chamber in the treatment of postoperative inflammation of cataract surgery; it can relieve postoperative pain and photophobia in patients undergoing radial keratotomy or laser refractive keratectomy, and is better than placebo.
Ingredients

Inhibits cyclooxygenase activity, thereby blocking the conversion of arachidonic acid to prostaglandins, while promoting the combination of arachidonic acid and triglycerides, reducing the concentration of free arachidonic acid in cells, and indirectly inhibiting the synthesis of leukotrienes. Its inhibitory effect on prostaglandin synthesis is stronger than that of aspirin and indomethacin, and it has a strong inhibitory effect on the collapse of the blood-aqueous humor barrier caused by mechanical, chemical, biological and other stimuli, and can reduce the flare and cell count in the anterior chamber, and relieve postoperative pain and photophobia.

Appearance
This product is a colorless or slightly yellow clear aqueous solution.
Indication
1. Used to treat uveitis, keratitis, scleritis, inhibit the formation of corneal neovascularization, treat inflammatory reactions after intraocular surgery, laser keratoconjunctivitis or various eye injuries, and inhibit the pupillary constriction reaction during cataract surgery; 2. Used for analgesia and anti-inflammatory after excimer laser keratectomy; allergic eye diseases such as spring conjunctivitis and seasonal allergic conjunctivitis, prevention and treatment of inflammation and macular cystoid edema after cataract and intraocular lens surgery, and promotion of filtration bleb formation after glaucoma filtration surgery.
Usage and Dosage
4 to 6 times a day, 1 drop each time; for ophthalmic surgery: 1 drop each time, 3, 2, 1, and 0.5 hours before surgery. Start taking the medication 24 hours after cataract surgery, 4 times a day, and continue for two weeks; start taking the medication 15 minutes after corneal refractive surgery, 4 times a day, and continue for three days.
Adverse Reactions
Eye drops may cause short-term burning, stinging, tearing, etc., and very few may have conjunctival congestion and blurred vision. Less than 3% of patients may experience systemic reactions such as fatigue, drowsiness, and nausea.
Precautions
It is contraindicated for those who are allergic to this product.
Special Population Medication
Precautions for children: The safety and effects of this product in children have not been investigated. Precautions for pregnancy and lactation: In animal teratogenicity studies, mice were given 5000 times the human topical dose (20 mg/kg/day), and rats and rabbits were given 2500 times (10 mg/kg/day), and no teratogenic effects were found, although these doses were toxic to the mother and fetus. The toxicity of diclofenac sodium to rat mothers was manifested as dystocia, prolonged pregnancy, and decreased fetal weight, growth, and survival rate. It has been shown that diclofenac sodium can pass through the placental barrier of rats and mice. However, there are currently no reports of studies in humans, so pregnant women should use it with caution. Precautions for the elderly: It is not yet clear.
