    Крахмал прежелатинизированный, гипролоза, коповидон, кросповидон, кальция гидрофосфат безводный, тальк, натрия лаурилсульфат, магния стеарат, гипромеллоза, макрогол 6000, титана диоксид, диметикон. Описание: овальные двояковыпуклые таблетки, покрытые пленочной оболочкой, белого цвета, с поперечной насечкой на одной стороне, разделяющей таблетку на две равные половины. На поперечном разрезе таблетки видно белое ядро и тонкое белое пленочное покрытие. антибиотик - азалид Код ATX: J01FA10 Фармакологическое действие Азитромицин - бактериостатический антибиотик широкого спектра действия из группы макролидов-азалидов. Механизм действия азитромицина связан с подавлением синтеза белка микробной клетки. Связываясь с 508-субъединицей рибосом, угнетает пептидтранслоказу на стадии трансляции и подавляет синтез белка, замедляя рост и размножение бактерий. В высоких концентрациях оказывает бактерицидное действие. Обладает активностью в отношении ряда грамположительных, грамотрицательных, анаэробов, внутриклеточных и других микроорганизмов. Микроорганизмы могут изначально быть устойчивыми к действию антибиотика или могут приобретать устойчивость к нему. A simple, precise and accurate reversed phase liquid chromatographic method has been developed for the assay of azithromycin in powder for oral suspension. The chromatographic separation was achieved on a Asahipak ODP 40 E(250 mm × 4.6 mm, 5 μm) analytical column. A mixture of methanol–ammonium dihydrogen phosphate (0.05M) (, v/v) (p H 9.0) was used as the mobile phase, at a flow rate of 1.5 m Lmin and detector wavelength at 210 nm. The retention time of azithromycin was found to be at 8.0 min. The validation of the proposed method was carried out for specificity, linearity, accuracy, precision, robustness and stability indicating assay. The linear dynamic range is from 382–1208 μgm L Azithromycin [9-de-oxy-9a-aza-9a-methyl-9a-homoerythromycin A dihydrate] is an azalide, a subclass of macrolide antibiotics as shown in Fig.1. It is derived from erythromycin; however it differs chemically from erythromycin in that a methyl substituted nitrogen atom is incorporated into the lactone ring, thus making the lactone ring 15 membered.

    Azithromycin has been analyzed by high-performance liquid. chromatography 1HPLC usingable in most laboratories. Liquid chromatography with UV detection has been already. Азитромицин — антибиотик широкого спектра действия. Это средство является прекрасным и эффективным средством в отношении большинства патогенных микроорганизмов. Azithromycin dihydrate ≥98% HPLC; CAS Number 117772-70-0; Synonym N-Methyl-11-aza-10Contact Technical Service. PZ0007 Sigma-Aldrich. Azithromycin dihydrate. ≥98% HPLC.

    Azithromycin is used to treat severe cases of thickened mucus caused by bacterial infections. Azithromycin is also used to treat severe cases of nasal congestion caused by sinusitis, to treat certain cases of pneumonia, to treat inflammation of the throat caused by bacterial infections, to treat certain bacterial skin infections, to treat inflammation of the urethra caused by bacterial infections, to treat inflammation of the cervix, to treat certain genital diseases in men, and to treat middle ear infections in children. Azithromycin should not be used to treat elderly patients, patients that require hospitalization, or patients who have severe health problems such as immunodeficiency. Azithromycin cannot be used to treat viral infections such as the common cold or flu. Azithromycin should also not be used to treat all bacterial infections as this may lead to the development of drug-resistant bacteria. It should only be used for the treatment of bacterial infections where it is effective. Azithromycin is a prescription medicine that belongs to a class of medicines called Macrolide Antibacterial. Macrolide antibacterials are a class of antibiotics that are used to treat certain kinds of bacterial infections. In this study, a high-performance liquid chromatographic method was developed for the quantitative determination of erythromycin (EM), roxithromycin (RXM), and azithromycin (AZM) in rat plasma with amperometric detection under a standardized common condition using clarithromycin (CAM) as an internal standard. This method was also proved to be applicable for the determination of CAM by employing RXM as an internal standard. Each drug was extracted from 150 μl of plasma sample spiked with internal standard under an alkaline condition with tert.-butyl methyl ether. The detector cell potential for the oxidation of the drugs was set at 950 m V. The linearity of the calibration curves were preserved over the concentration ranges of 0.1-10 μg/ml for EM and RXM, and 0.03-3.0 μg/ml for CAM and AZM. Coefficients of variation and relative error were less than 9% and ±7%, respectively.

The analytical method presented here was proved to be useful for the investigation of the pharmacokinetic characteristics of EM, CAM, RXM, and AZM in rats. This method was also proved to be applicable for the determination of CAM by employing RXM as an internal standard.

    Accutane (isotretinoin) is an acne medicine that quickly reached the U. market and become a best-settling prescription drug. Accutane drug was hailed by dermatologists as a breakthrough treatment for patients with severe acne. A number of generic equivalents of isotretinoin remain available today. It is still available in many countries outside of the United States. Within the United States, its generic form, isotretinoin, is available, and this drug is also marketed as under several different names within the United States: Claravis, Amnesteem, Sotret are a few of the best-known. Availability of generic Accutane (isotretinoin) available in many countries now and dominate the market. One of the most powerful treatments for severe cystic acne is a prescribed medicine called Isotretinoin. This drug was discovered in 1979, and it was used to treat patients with severe acne with successful (and lasting) results. Today, it is still the go-to treatment for severe acne that does not respond to retinol skin creams and antibiotics, as the results are fast, positive, and often permanent. Accutane chemical composition resembles that of retinoic acid, a compound derived from Vitamin A. Buy Accutane Online Without Prescription Treat Acne Forever Buy Accutane - Online LICENSED Drugstore!
