Problems solved by technology

A drug may show different effects and toxic reactions after being administered by different administration routes or administration sites, which is very common in pharmacy. Oral or intravenous administration of gatifloxacin and moxifloxacin can be used In the treatment of ophthalmic diseases [Document 1, Chen Zuji, the application research progress of gatifloxacin in ophthalmology, Journal of Optometry & Ophthalmology, Chinese Journal of Optometry & Ophthalmology, 2006, 8(6): 400-402; Document 2, Chen Zuji; Broad Spectrum Highly effective new fluoroquinolone antibacterial drug moxifloxacin and its application in ophthalmology, Ophthalmology Research, Chinese Ophthalmic Research, 2005, 06: 656-659;], however, cephalexin and cefadroxil can only be taken orally and cannot be injected The drug or the effect is very poor, ceftriaxone sodium, cefminox sodium, etc. can only be given by injection and cannot be taken orally or it is almost ineffective. Topical administration of cromolyn sodium eye drops or sprays can treat conjunctivitis or allergies or asthma etc. are effective, and are popular and commonly used drugs in the world, but the convenient oral tablets or capsules are worthless; a typical but not widely known example may also be: the toxicity of spectinomycin hydrochloride by intravenous injection is much higher than that by intramuscular injection Toxicity at the time, so that the drug can not be administered intravenously at therapeutic doses and can only be injected intramuscularly
[0015] In addition, our research found that the effect of low-dose antofloxacin is not satisfactory. In order to improve the compliance and efficacy of treatment, it is necessary to study whether antofloxacin can be used in the preparation of ophthalmic drugs or ophthalmic drugs for local administration of anti-infective diseases, etc. Obtaining valuable applications in otic medicine or skin external application, as well as suitable or valuable administration concentration or dosage or combined administration with steroidal or non-steroidal anti-inflammatory drugs, etc., etc., in On the basis of safety to improve curative effect, shorten the course of treatment, etc.
