Oxygen plasma was used to generate oxygen-containing functional groups on the surface of the compact to increase the wettability of the surface and the dissolution rate of the drug. Compacts of furosemide (300 mg) were produced using a stainless steel die and punch assembly, which was placed into a KBr press. The time of the plasma treatment was varied to assess the effect if any upon the dissolution rate and the wettability of the drug. Dissolution experiments of the plasma-treated and untreated compacts were carried out using the paddle apparatus method. Dissolution was carried out at 37\u00b0C using 1 L of 0.1 M HCl and phosphate buffer (pH 6). The wettability was assessed by contact angle measurements using the sessile drop technique. Untreated and plasma-treated samples were analysed by scanning electron microscopy at \u00d7 5000 magnification. Plasma treatment was found to lower the equilibrium contact angle from approximately 50 to 35\u00b0 but the dissolution rate was not significantly affected. This was attributed to fusion of the surface by the plasma treatment.<\/jats:p>","DOI":"10.1211\/0022357022070","type":"journal-article","created":{"date-parts":[[2003,12,1]],"date-time":"2003-12-01T23:48:55Z","timestamp":1070322535000},"page":"1473-1478","source":"Crossref","is-referenced-by-count":2,"title":["Effects of oxygen plasma treatment on the surface wettability and dissolution of furosemide compacts"],"prefix":"10.1093","volume":"55","author":[{"given":"A","family":"Naseem","sequence":"first","affiliation":[{"name":"Biomedical Materials Research Group, School of Pharmacy & Biomolecular Sciences, University of Brighton , Moulsecoomb, Brighton, BN2 4GJ,","place":["UK"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C J","family":"Olliff","sequence":"additional","affiliation":[{"name":"Biomedical Materials Research Group, School of Pharmacy & Biomolecular Sciences, University of Brighton , Moulsecoomb, Brighton, BN2 4GJ,","place":["UK"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"L G","family":"Martini","sequence":"additional","affiliation":[{"name":"GlaxoSmithKline, New Frontiers Science Park (South) , Third Avenue, Harlow, Essex, CM19 5AW,","place":["UK"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A W","family":"Lloyd","sequence":"additional","affiliation":[{"name":"Biomedical Materials Research Group, School of Pharmacy & Biomolecular Sciences, University of Brighton , Moulsecoomb, Brighton, BN2 4GJ,","place":["UK"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2003,11,1]]},"reference":[{"key":"2024103109394232300_cit1","doi-asserted-by":"crossref","first-page":"227","DOI":"10.1016\/S0378-5173(98)00020-9","article-title":"Surface treatment of the hydrophobic drug danazol to improve drug dissolution","volume":"165","author":"Brown","year":"1998","journal-title":"Int.
