Cefroxadine (CXD) capsules and dry syrup, an oral cephem antibiotic, were administered into 120 cases with ocular infections and the following results were obtained: The daily dose of CXD capsule was ranged from 500 to 1,500 mg and that of CXD dry syrup from 17.9 to 85.7 mg/kg, and the duration of CXD administration was from 2 days to 14 days. Clinical response rates classified by diagnosis The clinical response rates were 77.8% (14/18) in blepharitis, 86.7% (26/30) in hordeolum, 62.5% (5/8) in meibomianitis, 74.6% (44/59) in conjunctivitis, 100% (2/2) in corneal infiltration, 100% (1/1) in cellulitis of the lid, in dacryocystitis and in corneal ulcer, respectively. Clinical response classified by isolated organisms The response rates on S. aureus were 80.0% (20/25), on S. epidermidis 75.8% (47/62) and on S. pneumoniae 66.7% (2/3), respectively. The overall clinical response rate on Gram-positive bacteria was 78.3% (94/120). The response rates on H. influenzae, Acinetobacter spp., P. mirabilis, E. coli and Moraxella spp. were ranged from 42.9 to 100%. The sensitivity distributions of clinically isolated S. aureus and S. epidermidis to CXD were ranged from 1.56 to greater than 100 micrograms/ml and from 0.39 to 12.5 micrograms/ml, respectively. The former showed a peak at 3.13 micrograms/ml and the latter in 1.56 micrograms/ml. Side effects in 3 cases (2.3%) out of 129 were observed. That is; glossitis, thirst feeling and palpitation in each case, respectively.
