摘要

Disclosed are a method and dosage of eye drops containing 1.5 pcnt (w/v) of levofloxacin, characterized in that, when the eye drops are dropped into the eyes thrice a day, bacterial conjunctivitis can be healed within a short period of time, compared with the conventional case where 0.5 pcnt (w/v) eye drops are used thrice a day, without increasing the incidence of side effects. Healing of an eye infection within a short period of time contributes to shortening of the exposure time of a pathogenic bacterium causing the eye infection to levofloxacin. As a result, it is expected that, when used in the aforesaid method and dosage, the levofloxacin-containing eye drops inhibit the appearance of a resistant strain which is caused by the prolonged usage of levofloxacin-containing eye drops in the conventional method or dosage. Moreover, it is confirmed that, when used in the aforesaid method and dosage, the levofloxacin-containing eye drops directly inhibit the appearance of resistance, which is caused by the short-term usage of levofloxacin-containing eye drops in the conventional method or dosage, in pathogenic bacteria causative of eye infections such as Staphylococcus aureus.
