Fucithalmic in acute conjunctivitis. Open, randomized comparison of fusidic acid, chloramphenicol and framycetin eye drops.

Fucithalmic, which is 1% fusidic acid in a sustained-release eye preparation, was shown to be superior to both chloramphenicol eye drops and framycetin (Soframycin) eye drops in the treatment of bacterial conjunctivitis in Tanzania. The clinical success rate was 77/83 (93%) on fusidic acid compared with 22/46 (48% on chloramphenicol and 26/35 (74%) on framycetin (P less than or equal to 0.02). The better effect of fusidic acid could be ascribed to a much lower rate of in vitro resistance (17%) compared to chloramphenicol (58%) and framycetin (41%). Because of the low resistance rate to fusidic acid among eye pathogens, especially in areas of the world with a high resistance towards other commonly used eye anti-infectives, Fucithalmic given twice daily would seem to be a valuable new eye anti-infective.

[Bilateral deafness due to the local use of framycetin (author's transl)].

A case is reported of total bilateral cochleo-vestibular destruction following instillation of Framycetin into the middle ear, under pressure, through a transtympanic drain. Toxicity of Framycetin after local use is exceptional and only one case, reported by Ransome, was found in the published literature. The interest of this observation is that, by using puncture of the foot of the stapes, it was possible to find Framycetin in the perilymphatic liquid three weeks after the injection of the product.

Laboratory evaluation of topically used antibiotics: framycetin MIC and extinction time data for Pseudomonas aeruginosa.

Minimum inhibitory concentration (MIC) and extinction time (ET) of framycetin (0.5% in isotonic buffer) were determined. Of 90 consecutive clinical isolates of Pseudomonas aeruginosa, obtained from patients with ear or eye infections, 88.9% were inhibited by 62.5 mg/l and 96.66% were killed within 60 min by framycetin (0.5%). Determination of ET appears to be a promising technique for quantifying the bacterial action of high drug concentrations. Further clinical and experimental studies are required to see whether the ET predicts the efficacy of topical antibacterial preparations better than the MIC.

Incidence of neomycin and framycetin sensitivity.

A total of 450 consecutive patients were patch-tested to both neomycin and framycetin (20% in petrolatum). Thirteen patients were sensitive to both preparations, 10 to neomycin alone and four to framycetin alone. The significance of these results is discussed, with particular reference to the constituents of the preparations and the allergenic groups involved.

Identification and quantitation of polymyxin B, framycetin, and dexamethasone in an ointment by using thin-layer chromatography with densitometry.

A new thin-layer chromatographic-densitometric method has been developed for rapid identification and quantitative determination of polymyxin B, framycetin, and dexamethasone in a dental ointment. Silica gel 60 and F254 silica gel 60 plates were used for separating antibiotics and dexamethasone acetate, respectively. When determining framycetin and polymyxin B, chromatograms were developed by using 2 mobile phases, namely methanol and methanol-n-butanol-ammonia (25%)-chloroform (14 + 4 + 9 + 12, v/v/v/v/). The densitometric measurements were made at 550 nm after detection with 0.3% ninhydrin solution. Dexamethasone was determined by using the mobile phase cyclohexane-ethyl acetate (2 + 3, v/v) and ultraviolet densitometric recording at 245 nm. The results obtained for individual constituents with the chromatographic-densitometric method demonstrate similar accuracy, relative standard deviation values from 1.49 to 2.47%, and relative error values from 0.02 to 0.81% and are comparable to those obtained with the reference methods.

Analysis of neomycin sulfate and framycetin sulfate by high-performance liquid chromatography using evaporative light scattering detection.

A rapid and simple method for the determination of main components and related substances of both neomycin sulfate and framycetin sulfate by HPLC and evaporative light scattering detection (ELSD) is described. The method was also used to determine the neomycin B and the sample sulfate content. Detection and quantitation of aminoglycoside antibiotics are problematic because of the lack of UV absorbing chromophore. The use of a universal detector avoids the need for sample derivatization or use of specific detector based on pulsed amperometry described to be difficult in routine assays. Separation was performed with a Polaris C18 150 mm x 4.6 mm i.d., 3 microm reversed-phase column with a solution of 170mM trifluoroacetic acid (TFA) mobile phase at a flow rate of 0.2 mL/min. The chromatographic parameters were optimized with the help of experimental design software. Mass spectrometry (MS) was employed to confirm the ELSD profile. The final method was validated using methodology described by the International Conference of Harmonization in the field of Active Pharmaceutical Ingredients. Commercial samples of different sources were analyzed and results were in good agreement with specifications of the European Pharmacopoeia.

[Optimization of aerosol therapy in otorhinolaryngology: stability and granulometry of dexamethasone-gomenol-framycetin solution].

Nebulization of solutions associating gomenol, dexamethasone and framycetin is very widespread in otorhinolaryngology (particularly for the treatment of actue laryngitis and post-traumatic laryngitis and rhinitis and for the tracheotomy care). A rigorous clinical evaluation is however lacking. The aim of this work was to evaluate use of such solutions in comparison with the recommendations issuing from the National Session in April 1997 on good practices for aerosol therapeutics. Stability and granulometry were studied in order to optimize processing. A new formulation and new technical methods of administration are proposed in relation to the results of this study and the national recommendations.
