[Use of clindamycin-2-phosphate in ophthalmology (author's transl)]

Clindamycin-2-phosphate was studied to evaluate its possible use in ophthalmology. 1. Sensitivity of organisms isolated from human clinical materials: Of 44 staphylococcal strains in vitro studied 13 were highly sensitive to 0.1 mug/ml and 28 were resistant to 100 mug/ml or more of clindamycin-2-phosphate. 2. In experiments with rabbits, clindamycin-2-phosphate showed superior penetration into the ocular tissues after intravenous injection than after intramuscular injection. 3. Clindamycin-2-phosphate was administered intramuscularly at the dose of 300 mg to 6 healthy volunteers. The blood concentrations of 6 cases averaged 3.2 mug/ml after 1 hour, and 0.8 mug/ml after 6 hours. 4. Fourteen patients with extraocular infection were treated with daily intramuscular administration of 300 mg of clindamycin-2-phosphate. All of them improved by the treatment, and no side effect was observed.
