A base granulation was made with the active ingredient naftidrofuryl. The variables investigated included fractions of the excipients microcrystalline cellulose, lactose and dicalcium phosphate dihydrate. The release rate, crushing strength, friability and weight variation were determined as response parameters. Mathematical models were fitted to the data obtained by the lattice method, described by Scheffé and by means of multiple linear regression. Regression analysis indicated a relatively good fit of the models. On the basis of the regression models, contour plots were constructed. An increase in the amount of dicalcium phosphate caused lower release rate and increased weight variation. An increase in the content of lactose showed lower strength and increased friability, whereas an increase in the amount of microcrystalline cellulose had the opposite effect.</p>","PeriodicalId":7082,"journal":{"name":"Acta pharmaceutica Nordica","volume":"4 1","pages":"9-16"},"PeriodicalIF":0.0,"publicationDate":"1992-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12683777","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 activation parameters, the solvent isotope effect and the effect of the dielectric constant on the degradation rate were determined, and possible degradation mechanisms were discussed.

The in vitro dissolution profile as well as the leakage of radioactivity from the drug particles were determined using a through-flow cell method. The radioactive drug particles were mixed with a lactose carrier and inhaled from a dry powder device by five healthy volunteers. The removal of the inhaled drug particles from the lungs was evaluated by a gamma camera. A close relationship between the dissolution of the drug as such and the leakage of radioactivity was noted. Gamma scintigraphy indicated a biphasic exponential removal of radioactivity from the lung region. The slow component with the halftime of about 55 min was mainly due to the dissolution of drug particles in the lungs. The halftime of the fast component describing mucociliary clearance was less than 10 min. This process was the dominating one for the removal of the drug from the lungs. The experiment thus showed that the main fraction of the inhaled dose was deposited in the tracheobronchial region. Accordingly, only a small portion of the dose initially deposited in the lung can be absorbed and induce a therapeutic effect.</p>","PeriodicalId":7082,"journal":{"name":"Acta pharmaceutica Nordica","volume":"3 3","pages":"155-8"},"PeriodicalIF":0.0,"publicationDate":"1991-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12956684","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}
