In this context, quality control must accompany the process from the acquisition of raw material to the transformation into a finished product, since its goal is to ensure safe and effective drugs for human or animal consumption. Considering the significant increase in veterinary prescriptions containing antimicrobial drugs, the present work carried out a search for information about the qualification of veterinary preparations available in the national market, highlighting, through legislation, the quality parameters applied to pharmaceutical products for veterinary use. The quality of solid pharmaceutical preparations containing cephalexin, acquired in the national veterinary pharmaceutical market, was also evaluated. The six different brands of cephalexin tablets and coated tablets analyzed in this study were approved with regard to identification, average weight, determination of mechanical strength in tablets, disintegration test, and content. The results of the determination of the content varied between 94.9% and 103%, being within the limits indicated for preparations for human use, as recommended by USP 44 and the Brazilian Pharmacopeia 6th edition. Even so, it is important to emphasize the need for improvement in the legislation that regulates the quality control of medicines for veterinary use, since the norms are not very specific, with an absence of parameters, specifications, and release procedures that ensure which tests should be performed. This study is a perspective that can bring subsidies for investigations of other therapeutic classes, considering the large number of formulations available in the Brazilian market of veterinary medicines.","PeriodicalId":11314,"journal":{"name":"Drug Analytical Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86309192","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The drug was determined using a phase reverse system and the separation was performed in an analytical C18 column (250 mm x 4.6 mm, 5 μm). The mobile phase consists of 0.1% orthophosphoric acid and methanol in a 25:75, v/v ratio. Using a concentration range of 10–90 μg mL-1, the technique demonstrated a strong linear response (r=0.999). Effluents were measured at 262 nm while the flow rate was kept at 1.0 mL min-1. There was a retention time of 3.506 min. The method was statistically validated to determine its accuracy, precision, linearity, ruggedness, robustness, solution stability, selectivity, and forced degradation assessments. The stresses that were used were acid, alkali hydrolysis, water stress, oxidation, photolysis, and heat. Since the degradation products did not affect the capacity to identify ebastine, this technique may be taken as a stability indication. This methodology may be utilized for the analysis of Ebastine in pharmaceutical suspension, since the findings obtained were within the limits set by ICH standards.","PeriodicalId":11314,"journal":{"name":"Drug Analytical Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88640660","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This mini-review contemplates the current technological vision of pharmaceutical analysis through Green Analytical Chemistry (GAC). Green and sustainable methods have a main focus providing economic, environmental and social benefits. An example is spectrophotometry in the infrared region for quantitative purposes. The purpose of this mini-review is to show a practical guide for the quantitative analysis of raw materials and pharmaceutical products by spectrophotometry in the infrared region in order to contribute to a sustainability cycle, where the guarantee of product quality and the analytical awareness about health, time, waste generation, environment and cost coexist. A practical review for quantitative analysis by spectrophotometry in the infrared region was shown. It is useful for routine analysis of pharmaceutical products in general, and it can be used by chemical-pharmaceutical laboratories around the world.","PeriodicalId":11314,"journal":{"name":"Drug Analytical Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83869743","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Method I is simultaneous equation method (Vierodt’s Method), which is based on measurement of absorption at 251 and 227 nm i.e. λmax of Efonidipine Hydrochloride Ethanolate and Chlorthalidone, respectively. Method II is first order derivative was based on the measurement of absorbance of Efonidipine Hydrochloride Ethanolate measure at 283.2 nm (ZCP of Chlorthalidone) and absorbance of Chlorthalidone measure at 250.8 nm (ZCP of Efonidipine Hydrochloride Ethanolate). Linearity was observed in the concentration range of 6.4-38.4 µg.mL-1 for Efonidipine hydrochloride ethanolate and 2-12 µg.mL-1 for Chlorthalidone using methanol as a solvent. The accuracy of methods was assessed by recovery studies and was found to be within range of 98-102% for both the drugs. Precision of the methods was estimated by repeatability and intermediate precision studies. The % RSD values were found to be less than 2, proving methods were precise.

Formulations were prepared by PIT emulsification process. Seventeen emulsions containing different amounts of GSO, AVO and OMC were obtained according to experimental design. In vitro SPF was determined using a spectrophotometric method. As expected, formulations with the highest concentrations of UV filters, AVO and OMC, resulted in the highest SPF values, while the lowest SPF values were obtained by formulations containing concentrations of these filters below the central point. In the tested concentrations, the variable OMC and its combination with GSO showed to influence the SPF linearly as a function of their concentrations in formulations. The combination of GSO with OMC contributed to increase in vitro SPF. The use of natural compounds with antioxidant activity, such as GSO, is a viable strategy to increase the effectiveness of sunscreens to protect the human skin against UV-induced damage.","PeriodicalId":11314,"journal":{"name":"Drug Analytical Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84441896","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, the kinetic degradation under UVC radiation was studied, as well as the penetration/permeation and the ocular irritant potential of DEET repellents in the form of solution, lotion and gel. The photostability study was conducted over 96h, and the DEET degradation kinetics under UVC radiation was fitted to the zero-order model for the three formulations; t90% values of 23.7 h, 17.0 h and 16.1 h were obtained for gel, lotion and solution forms, respectively. The in vitro skin penetration/permeation using the vertical Franz cell in pig skin showed that all the formulations penetrated/permeated the skin layers, at a higher rate when the lotion (p<0.05) was used, possibly due to its qualitative composition. The in vitro ocular irritant potential using the HET-CAM method indicated that one of the products evaluated was classified as \"moderate irritant\" and five as \"severe irritant”. The set of data indicated the lower penetration/permeation of the solution form and reinforces the importance of being careful during application, to avoid accidental contact with the eyes.","PeriodicalId":11314,"journal":{"name":"Drug Analytical Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85848828","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
