The hydrosoluble fiber Plantago ovata husk improves levodopa (with carbidopa) bioavailability after repeated administration.
The influence of treatment duration (7 or 14 days) with Plantago ovata husk/levodopa/carbidopa in the bioavailability and other pharmacokinetic parameters of levodopa were evaluated in rabbits. Fiber was administered at two different doses, 100 and 400 mg/kg, and the dosage of levodopa/carbidopa was 20:5 mg/kg. These doses were administered once a day. When 100 mg/kg of fiber was administered, ...
متن کاملStudy of the protective effect on intestinal mucosa of the hydrosoluble fiber Plantago ovata husk
BACKGROUND Several studies have indicated that dietary fiber may have a protective effect on gastrointestinal mucosa. The aim of this study was to evaluate the protective action of the soluble fiber Plantago ovata husk against intestinal damage. METHODS To evaluate the anti-ulcerogenic effect on duodenal mucosa of the soluble fiber Plantago ovata husk, low-dose acetylsalicylic acid (10 mg/kg)...
متن کاملInfluence of Plantago ovata husk (dietary fiber) on the bioavailability and other pharmacokinetic parameters of metformin in diabetic rabbits
BACKGROUND Metformin is an oral hypoglycemic agent frequently used in patients with type 2 diabetes. In this study, we have investigated the influence of the dietary fiber Plantago ovata husk on the pharmacokinetics of this drug when included in the diet, as well as when administered at the same time as metformin. METHODS Six groups of 6 rabbits were used. Groups 1 to 3 were fed with standard...
متن کاملEffects of Plantago ovata husk on levodopa (with Carbidopa) bioavailability in rabbits with autonomic gastrointestinal disorders.
Gastrointestinal dysfunction is common in Parkinson's disease. Fiber therapy could be used to reduce the symptoms of gastrointestinal motility disorders. In a previous study, we showed that slowed gastrointestinal motility modified levodopa pharmacokinetics: area under the plasma concentration-time curve (AUC) and maximum plasma concentration (C(max)) decreased and the elimination was delayed. ...
متن کاملThe gel-forming polysaccharide of psyllium husk (Plantago ovata Forsk).
The physiologically active, gel-forming fraction of the alkali-extractable polysaccharides of Plantago ovata Forsk seed husk (psyllium seed) and some derived partial hydrolysis products were studied by compositional and methylation analysis and NMR spectroscopy. Resolving the conflicting claims of previous investigators, the material was found to be a neutral arabinoxylan (arabinose 22.6%, xylo...
