title: A new approach to encapsulating nonsteroidal anti-inflammatory drugs. IV. Effect of cellulose derivatives with different functional groups on the bioavailability and gastric ulcerogenic activity of acidic as well as basic nonsteroidal anti-inflammatory drugs.
abstract: The bioavailability and gastric ulcerogenic activity of oxyphenbutazone and glafenine (acidic and basic nonsteroidal anti-inflammatory drugs), coated with different cellulose derivatives were assessed in albino rats. The cellulose derivatives chosen have different functional groups, acidic (carboxymethyl cellulose), basic (chitosan) and neutral (hydroxypropylmethyl cellulose). The bioavailability was dependent on the drug and polymers. Generally, all the cellulose derivatives chosen decreased the gastric ulcerogenic activity of the drugs studied.
