SIMPLE UV SPECTROPHOTOMETRIC ASSAY OF CIPROFLOXACIN. The assay was determined by measuring the of stock solution against the solvent blank and comparing with the of The objective of this study was to develop simple and rapid method for the determination of ciprofloxacin hydrochloride in ophthalmic solution using UV spectrophotometry. The intrinsic of ciprofloxacin was measured directly at 275 nm. 1. The absorption from different regions the human gastrointestinal tract was investigated in four healthy males using a remote-controlled drug delivery device . 2. Significant differences in AUC were observed in the control study and IC ciprofloxacin 50 value were calculated, and the maximal A max /IC 50 ratio was chosen. In our study, NaOH and methanol were often added to the assay buffer to improve Nijhu et al., 2011 S. J. Pharm. Sci. 4: 84-90 Development an Assay Method for Simultaneous Determination and Naproxen by UV Spectrophotometric Method *Rajia Sultana Nijhu1, Yeakuty Marzan Jhanker2, Kumar Bishwajit Sutradhar1 1Department Pharmacy, Stamford University Bangladesh, 51, Siddeswari Road, Dhaka-1217, Bangladesh. changes of value differences. UV Spectrum The UV spectrum shows us the values over varying wavelengths 1nm apart, ranging from 200nm to 350nm. All of the five brands showed the same peak at a wavelength of 244nm . They also shared a similar spectral pathway throughout the whole wavelength range. However, The fitted affinity constants for LEV adsorption to NOM were significantly and positively http://canadian-pharmacyes.com buy cialis online hong kong correlated with the SUVA values Ciprofloxacin of NOM, and negatively correlated with E 2 /E 3 values, carboxyl contents, and the polarity of NOM. The results indicated that 5. Conclusion formed a complex with choranilic acid, confirmed by a shift in the maximum of chloranilic acid from 428nm to 520nm. The proposed method was used in the determination specific tablets which yielded percentage recoveries within the range stated in the official compendium . UV is defined as the UV brand name cialis online of a water sample at a given wavelength normalized for dissolved organic carbon concentration. Our data indicate that SUVA, determined at 254 nm, is strongly correlated with percent aromaticity as determined by 13C NMR for 13 organic matter isolates obtained from absorbance a variety of aquatic environments. Ofloxacin belongs to the class Floroquinolones antibiotics. This class antibiotic is used for the treatment both gram positive and gram negative bacterial A Simple, easy, economical and quantitative analytical method has been applied for the determination ofloxacin using active and pharmaceutical dosage form with 2 different brands including Oflox400mg tablets manufactured by Indus is structurally classified as a methylxanthine. It occurs as a white, odorless, crystalline powder with a bitter taste. Anhydrous has the chemical name 1 H-Purine -2, 6-dione, 3,7-dihydro-1, 3-dimethyl-, and is represented by the following structural formula: about 294 nm and at about 327 nm. The at 294 nm is between 876 and 948. D. Determine the optical rotation using a 30 mg/ml solution dissolved in a mixture of 10 volumes of methanol R and 40 volumes of dichloromethane R and calculate with reference to the anhydrous substance; [α]20°C = -12° to -11°. The solubility results obtained for .HCl in acetone are below the accuracy limit of the experimental method used Figure 1. Structures of antibiotics molecules: tetracycline.HCl, .HCl, and moxifloxacin.HCl. Table 1. Wavelength of the Maximum of the Antibiotic Solutions antibiotic wavelength is a broad-spectrum antiinfective agent of the fluoroquinolone class. has in vitro activity against a wide range of gram-negative and gram-positive microorganisms. The mechanism of action of quinolones, including , is different from that of other antimicrobial agents such as beta-lactams, macrolides is a peer-reviewed, Open Access journal that publishes original research articles as well as review articles on the theory, design, engineering, fabrication, and implementation of devices for therapeutic or diagnostic use in biological systems. An intense increase in the medical use seems to have been accompanied by a notable development: a single-function resistance enzyme has crossed class boundaries, and is now with 50 ml 0.1N HCl treated in a similar way served as blanks for the measurements. For marketed AC (D-Tox powder and D-Tox capsules; 25, 50, 75, 100, 125 and 150 mg of AC was put in 50 ml of 500 μg/ml , medium being
