那他霉素滴眼液怎么滴,滴多少？

Fungal keratitis is an infectious corneal disease caused by pathogenic fungi with a high rate of blindness. In recent years, due to the irregular use of antibiotics and hormones, the incidence of fungal keratitis has been on the rise. Fungal keratitis often occurs during the busy farming season and is more common in young adults and the elderly. It is currently one of the most difficult to treat keratitis. Unlike fluconazole and amphotericin B, natamycin eye drops are the first topical antifungal drug approved by the US FDA for production. It is a polyene macrolide antifungal agent with a wide antifungal spectrum and has broad-spectrum, dual-effect antifungal effects. So, how to drip and how much to drip?

Please shake natamycin eye drops well before use. The optimal starting dose is 1 drop each time, instilled once every 1-2 hours into the conjunctival sac. After 3-4 days, change to 1 drop each time, 6-8 times a day. Treatment generally lasts for 14-21 days or until active fungal keratitis subsides. In most cases, gradual reduction of the drug dosage every 4-7 days is necessary to ensure elimination of pathogen replication. The initial dose for the treatment of fungal blepharitis and conjunctivitis can be smaller, 1 drop each time, 4-6 times a day.

The prospect of natamycin eye drops is very competitive

There will be no systemic adverse reactions when natamycin is applied topically to the eye, but occasional ocular adverse reactions (such as foreign body sensation, irritation, pain), itching, mild conjunctival congestion and edema, and mild corneal epithelial erosion may still occur. Most of these adverse reactions are mild, do not affect the efficacy, and have no sequelae. After many years of clinical application in ophthalmology and other fields, it has been proven that natamycin eye drops have good antibacterial effects and few adverse reactions in terms of antifungal effects, and are very competitive in ophthalmic application prospects.
