Pharmaceutical Technology Europe. This article presents a simple and systematic approach to HPLC method development, beginning with sample preparation and finishing with practical analytical method validation.

A rapid, simple, and sensitive RP-HPLC analytical method was developed for the simultaneous determination of triclabendazole and ivermectin in combination using a C18 RP column. The mobile phase was acetonitrilemethanolwateracetic acid 56 36 7. A nm UV detection wavelength was used.

A reliable, selective and sensitive stability-indicating RP-HPLC assay was established for the quantitation of bromazepam BMZ and one of the degradant and stated potential impurities; 2- 2-aminobromobenzoyl pyridine ABP.

In the current scenario, the stability problems of phytoconstituents are a major problem for regulators and because of the complex nature of the components of plant extracts.


High performance liquid chromatography is one of the most accurate methods widely used for the quantitative as well as qualitative analysis of drug product and is used for determining drug product stability. Stability indicating HPLC methods are used to separate various drug related impurities that are formed during the synthesis or manufacture of drug product. This article discusses the strategies and issues regarding the development of stability indicating HPLC system for drug substance. A number of key chromatographic factors were evaluated in order to optimize the detection of all potentially relevant degradants. The method should be carefully examined for its ability to distinguish the primary drug components from the impurities.

High performance liquid chromatography HPLC is an analytical technique which is proficient to separate, detect and quantify various drugs and its related degradants. An appropriate mobile phase, column, column temperature, wavelength and gradient must be found that affords suitable compatibility and stability of drug as well as degradants and impurities.

Carvone volatile oil is a commercial product that is widely used in the food, cosmetic and pharmaceutical industry due to its fragrance, flavoring and medicinal properties. A validated HPLC method for the qualitative and quantitative analysis of this oil in raw and commercial products is not available in the literature. The aim of this study is to develop a validated new analytical HPLC method for the estimation of Carvone in raw materials and suppositories. The mobile consists of two phases Methanol and 1. The developed HPLC analytical method was simple and was validated in accordance with FDA and ICH guidelines and showed good linearity, accuracy, precision, selectivity and the system suitability results were within the acceptance criteria. This new analytical method could be used to screen the quality of the oil in formulation studies of the final product formulations and can be applied for routine analysis of carvone in raw material as well as in pharmaceutical suppositories and can be applied in any lab and industrial batch quality control. Alternative and complementary medicines are hugely used in the treatment of different ailments including the inflammatory bowel disease IBD Jagtap et al.


Objective: The present work was undertaken with an aim to develop and validate a rapid reverse-phase high-performance liquid chromatography RP-HPLC method for the estimation of curcumin and cyclosporine in the capsule dosage form. Separation of drugs was achieved in an isocratic mode and elution was monitored using PDA detector at nm. Results: Retention time of the curcumin and cyclosporine were found to be 3. Conclusion: The proposed method was found accurate, precise and specific for the determination of curcumin and cyclosporine in bulk as well as in capsule dosage form. Thus, the present method can be used for routine analysis and quality control of curcumin and cyclosporine in bulk and capsule dosage form.

A new selective and sensitive high-performance liquid chromatography HPLC method was developed for the quantification of diclofenac sodium DS in pharmaceutical dosage form using lidocaine as internal standard IS. Chromatographic separation was achieved on a symmetry C18 column 4. The method was validated to fulfill International Conference on Harmonisation ICH requirements and this validation included specificity, linearity, limit of detection LOD , limit of quantification LOQ , accuracy, precision and robustness. All results were acceptable and this confirmed that the method is suitable for its intended use in routine quality control and assay of drugs. Diclofenac sodium [N-piperidino 4-chlorophenyl 2,4-dichlorophenyl methylpyrazole-carboxamide] is one of the analgesic-antipyretic-nonsteroidal anti-inflammatory drug.

Кольцо, - совсем близко прозвучал голос. Беккер поднял глаза и увидел наведенный на него ствол.

HPLC Method Development and Validation for Pharmaceutical Analysis

Халохот был мертв. Беккер отшвырнул пистолет и без сил опустился на ступеньку. Впервые за целую вечность он почувствовал, что глаза его застилают слезы, и зажмурился, прогоняя влажную пелену.

 С вами хочет поговорить начальник шифровалки. Она сейчас будет. - Она? - Беккер рассмеялся.

 - Сюрреализм. Я в плену абсурдного сна. Проснувшись утром в своей постели, Беккер заканчивал день тем, что ломился в гостиничный номер незнакомого человека в Испании в поисках какого-то магического кольца.
