what medichs used treat trachoma? How to treat and control trachoma? Antibiotic treatment is very important for the cure of active trachoma infection crowd. Since the early 1950s the 20th century, trachoma treatment rely mainly on the long-term use of local tetracycline.Chlamydia trachomatis is sensitive to some antibiotics, including sulfa drugs, erythromycin and tetracycline. Tetracycline eye ointment is wildly used for its low prices and reliable results. Tetracycline is effective for reduce the inflammatory trachoma prevalence and severity in the short term, but such treatment was considered suppression, not curative, so it needs a long term to be effective. 1% tetracycline eye ointment need to be taken two times a day, for a total time of six months, or take intermittent treatment, 2 times a day, for continuous 5 days per month, or one day per month, for continuous ten day per month for six months a year. Individual partial use of tetracycline will lead to the disappearance of Chlamydia trachomatis infections and secondary bacterial infection reducted. This will reduce the existed and serious eye infection in a short-term, but the other chlamydia infection were not affected, the eyes will be infected again. In addition, if in community not all infected persons receive effective treatment, the spread of chlamydia could be restarted. The endemic areas should take group treatment and family therapy, that is to take the antibiotic treatment for activities of trachoma patients or individual / family, and systemic antibiotic therapy should be added for the serious patients. Use sulfa initially, but it was replaced by tetracycline and oxytetracycline later. Oral tetracycline: 250 mg, four times a day for total three weeks. 100mg，Or doxycycline 100 mg, once a day for total three weeks. For children and pregnant women, use 250 mg erythromycin, four times a day for total three weeks. Recently in the Gambia, Egypt and Saudi Arabia, studies show that one-time oral drink 1 grams azithromycin has a good effect to the treatment of Chlamydia trachomatis, but the price of azithromycin is high, that`s should be concerned. | |
