Published: September 2024

Background: The World Health Organisation has advocated the use of generic medicines to make them accessible and affordable but studies have revealed that marketed products do not produce same therapeutic effects and hence are not interchangeable. Dissolution testing of generic solid dosage forms serves as a valuable tool for acquiring dissolution profiles and for assessing the similarity or dissimilarity between the formulations under examination.
Objectives:

To evaluate the in-vitro drug release profiles of different generic brands of Itopride Sustained release capsules that are commercially available in Indian market and compare them with the innovator product using model dependant and as well as model independent methods.
To determine whether same medicine manufactured by different brands are interchangeable.

Materials & Methods: In this study Eight generic brands of Itopride 150mg sustained release capsules available in the Indian market were evaluated using dissolution test with the aim to assess their bioequivalence with the innovator product (Ganaton OD). Dissolution studies were performed using USP type II apparatus at 100 rpm in 900 ml 0.1N HCl while maintaining a temperature of 37±0.5 ºC. The samples were estimated by a validated HPLC method.
Dissolution test results were statistically evaluated by employing both model dependant and model independent methods. In model dependant experimental data obtained for each dissolution profile were transformed by applying the equations of different kinetic models and the best-fit model was selected whereas in model independent approach fit factors, dissolution efficiency and mean dissolution times were calculated.
Results: The Weibull model best explained the release of drugs from all the brands. Upon statistical evaluation of dissolution test results its was found that while similarity factor f2 was within the limits for all generic brands, difference factor f1 of two brands was out of acceptable range thus questioning their bioequivalency with the innovator product. Also the dissolution efficiency of four out of the brands was out of acceptable limits.
Keywords: bioequivalence, difference factor (f1), similarity factor (f2), dissolution profile, comparison and evaluation..

Published: September 2024

A traqueostomia tem como finalidade realizar uma abertura na parede anterior da traqueia, onde será colocada a cânula de traqueostomia, para permitir a passagem de ar até às vias aéreas. Na traqueostomia depois de um período ocorrem mudanças nas estruturas anatômicas, que interferem no processo fisiológico da deglutição, mais de 50% dos traqueostomizados apresentam alterações da deglutição. A decanulação é o processo destinado à retirada da cânula de traqueostomia do indivíduo. É bem claro e definidas as indicações para TQT, entretanto, para seu desmame e decanulação não se observa regras bem estabelecidas. O objetivo deste estudo é elaborar um protocolo que conduza a equipe de fisioterapia no processo de desmame da decanulação traqueal. É um estudo metodológico, construído em duas etapas: uma revisão de literatura integrativa, utilizando os descritores traqueostomia, desmame e adulto, contemplando publicações de 2019 a 2023, com critérios de inclusão e exclusão bem estabelecidos e por último elaborado um protocolo de acordo com a literatura atual. Com respaldo na literatura mais recente construiu-se um protocolo para desmame de decanulação traqueal: padronização para conduta da fisioterapia, contemplando os dados de identificação do paciente, avaliação respiratória, nível de consciência, sinais vitais e teste de oclusão de traqueostomia. Conclui-se que os principais critérios considerados no desmame da decanulação traqueal foram desinsuflação do cuff, oclusão de traqueostomia, capacidade para manejo de secreções, tosse, deglutição, nível de consciência, entre outros. Ainda são necessários mais estudos que abordem essa temática.

This study investigates the potential of dandelion (Taraxacum officinale) root ethanol extract as a green corrosion inhibitor for two types of steel (TH-550 and TS-275) in a chloride-rich environment. Steel samples were chemically prepared and immersed in a 3% NaCl solution, both without and with the extract at concentrations of 0.5, 1.0, and 1.5 g/L. Morphology and composition of steel samples after 24 h in blank and inhibited solutions, examined by SEM and EDX, revealed the inhibitive effect of dandelion extract, since corrosion products were not visible on the steel surfaces after 24 h in the inhibited solution, unlike the blank steel surfaces. Based on the weight loss, dandelion extract inhibited corrosion processes of S2 in a chloride-rich environment at all examined concentrations; on the other hand, it acted as a corrosion inhibitor of S1 in 3% NaCl only at the concentrations of 1.0 and 1.5 g/L. According to corrosion current, corrosion potential and polarization resistance determined by potentiodynamic tests, dandelion root extract is a mixed corrosion inhibitor with a dominant anodic reaction, which decreases corrosion rate by adsorbing onto anodic sites and prevents steel dissolution. According to ATR-FTIR analysis, hydroxyl groups within the inulin molecule could act as the dominant metal-complexing groups. Therefore, the adsorption properties of dandelion root extract are most probably related to this specific site. Based on electrochemical impedance spectroscopy, the enhancement of corrosion resistance in the steel samples was evident in all the inhibited solutions examined compared to a pure 3% NaCl solution.
