Percutaneous Absorption of Drugs

Annual Review of Pharmacology and Toxicology, 1989
Some practical applications of basic information in percutaneous absorption have been reviewed. Drug release from vehicles is discussed in relation to glucocorticosteroids. Penetration enhancers are reviewed with emphasis on the need for further investigations and applications of enhancers for clinical use.

EPIDERMAL ABSORPTION OF DRUGS

Archives of Dermatology, 1948
CERTAIN ethylene series are absorbable when applied on the intact skin by gentle spreading. This has suggested the possibility of the use of one of these glycols alone or in mixture with other agents, as a vehicle or carrier for drugs, to promote or enhance their percutaneous absorption.

Drug Absorption II: Effect of Fasting on Intestinal Drug Absorption

Journal of Pharmaceutical Sciences, 1969
The effects of fasting on the intestinal absorption profiles of salicylic acid, barbital, haloperidol, and chlorpromazine were studied in anesthetized rats. The in situ technique employed in this study yielded absorption rate constants which were realistic and comparable to those observed following oral drug administration. The weak acids, barbital and

Experimental modelling of drug absorption and drug absorption interactions

International Journal of Pharmaceutics, 1986
Abstract Five experimental models of drug absorption were evaluated using chloroquine and phenobarbitone as tracer drugs. Their absorption was followed at different pH values and in the absence and presence of the interactants kaolin and activated charcoal.

Migraine and Drug Absorption

Clinical Pharmacokinetics, 1978
The majority of migraine attacks are associated with gastrointestinal symptoms which add considerably to the distress and inconvenience caused by the headache. When salicylate absorption from effervescent aspirin tablets was studied during migraine, the rate of absorption was found to be reduced relative to that found in non-migrainous volunteers and ...

Free Diffusion in Drug Absorption

2021
Absorption is a mass transfer process that involves the passage of intact drug molecules from the site of absorption (which often, but not always, corresponds to the site of administration) to the bloodstream. Free diffusion is the most common absorption mechanism for drugs.

Interactions Affecting Drug Absorption

Clinical Pharmacokinetics, 1984
The influence of drug-drug and drug-food interactions affecting the absorption of orally administered medication is reviewed. Drug-drug interactions can be classified in terms of indirect effects by one drug on gastrointestinal tract physiology influencing the absorption of other drugs, or direct interactions involving altered pH, adsorption ...

Drug absorption in celiac disease

American Journal of Health-System Pharmacy, 2013
Published evidence on established and theorized effects of celiac disease on drug absorption and pharmacokinetics is reviewed.Patients with celiac disease develop a variety of gastric disorders requiring oral medications, but the impact of damage to intestinal villi and other celiac disease sequelae on drug absorption remains poorly understood.

Maximum entropy and drug absorption

Journal of Pharmacokinetics and Biopharmaceutics, 1991
The application of maximum entropy to the calculation of drug absorption rates was introduced in an earlier paper. Here it is developed further, and the whole procedure is presented as a problem in scientific inference to be solved using Bayes' theorem.
