ABSTRACT
OBJECTIVE:To study the compatible stability of Cefmenoxime for injection with Ganciclovir for injection in 0.9% Sodium chloride injection and 5% Glucose injection. METHODS:At room temperature,the appearance and pH of the mix-tures were observed after Cefmenoxime for injection was compatible with Ganciclovir for injection. HPLC method was adopted to determine the content of them. RESULTS:No significant change was noted for the mixture in appearance and pH value. The con-tent of ganciclovir was more than 98%,but that of cefmenoxime decreased to 75.33%. CONCLUSIONS:Cefmenoxime for injec-tion can not be mixed with Ganciclovir for injection in 0.9%Sodium chloride injection and 5%Glucose injection .
ABSTRACT
Objective To investigate thermal degradation kinetic characteristics of Cefmenoxime Hydrochloride in infusion solutions, and predict its thermal stability. Methods The HPLC was applied to determine the contents of Cefmenoxime Hydrochloride. Classical isothermal kinetic method and multivariate linear model were used to predict the expiration date of the injection. Results It was found that the thermal degradation kinetics of Cefmenoxime Hydrochloride in two infusion solutions corresponded with the first-order kinetics. The expiration dates of Cefmenoxime Hydrochloride in 0. 9%sodium chloride injection calculated by two different methods were 2. 20 days and 1. 52 days,and in 5% glucose injection were 2. 09 days and 1. 53 days,respectively. Conclusion The thermal stability of Cefmenoxime Hydrochloride in infusion solutions is poor and its expiration dates are the same calculated by two different methods.
ABSTRACT
PURPOSE: Neisseria gonorrhea is usually identified in neonatal conjunctivitis, but rare in adult keratoconjunctivitis. We report a rare case of bilateral gonococcal conjunctivitis combined with keratitis. METHODS: A 29-year-old male with a history of sexual contact with a prostitute 17 days ago referred to our hospital with acute keratoconjunctivitis. Ocular discharge was examined by Gram stain, culture, and sensitivity test to antibiotics, resulting in the identification of penicillin-resistant Neisseria gonorrhea. RESULTS: This patient was treated with intramuscular ceftriaxone for 5 days and topical cefmenoxime 0.5% for 2 weeks. Following 24 hours after antibiotics medication, the clinical symptoms were improved, and follow-up culture was negative. No evidence of serious complication was left in the cornea and conjunctiva. CONCLUSIONS: As adult gonococcal keratoconjuctivitis is relatively rare, the clinical diagnosis may be delayed. When one suspects an adult gonococcal keratoconjunctivitis, immediate gram staining and confirmatory culture for isolation of gram-negative intracellular diplococci are mandatory. It should be remembered that intramuscular ceftriaxone and topical cefmenoxime are an effective treatment for this condition.
