This method is applicable for estimation of those drugs whose spectra overlap properly I.e. If a sample contains two absorbing drug each of which absorbing at λmax of the other, it is possible to determine both drugs by technique of simultaneous equation method. This article consists of the list of various combined dosage form and food sample analyzed by Vierodt’s method with its wavelength, linearity range and choice of solvents. This method permits simple, rapid and direct determination of combined dosage form without prior separation and therefore can be used in routine analysis. Quantitative estimation is necessary before introduction of any drug into the market because if concentration is more in formulation it can lead to toxicity problem or if concentration is found less, then formulation will not be effective in prescribed dose.","PeriodicalId":8547,"journal":{"name":"Asian Journal of Pharmaceutical Analysis","volume":"8 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74933385","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}

When used in combination with in vitro dissolution tests, the BCS can maintain the prediction of in vivo product performance and the development. Filtration is critical in drug dissolution testing as filtration stops the dissolution process and allows for accurate quantitation through separation of dissolved and un-dissolved components. The objective of this investigation was to determine if other sinker shapes will influence the rate, extent, or variability of dissolution. Dissolution test is required to study the drug release from the dosage form and its in vivo performance.
