The possible interactions between these two drugs were studied in C57Bl/6J mice bearing the Lewis Lung Carcinoma (3LL). The anticoagulant activity of heparin was temporarily reduced by concomitant treatment with adriamycin, as indicated by both activated partial thromboplastin times and blood recalcification times. In contrast, no changes were found in the kinetics of adriamycin disappearance from blood and accumulation in tissues if mice had been pretreated with heparin. Moreover, the effect of adriamycin on tumour and metastasis growth was unchanged by the association with the anticoagulant.

Circadian, circannual and other rhythmic changes in biological susceptibility and response of organisms to a large variety of physical as well as chemical agents including medications and foods are rather common phenomena. Modern chronopharmacology investigates drug effects: a) as a function of biological timing and b) upon parameters characterising the endogenous bioperiodicities. A better understanding of periodic and thus predictable changes in drug effects can be attained through consideration of three complementary concepts: the chronokinetics of a drug (rhythmic changes in its pharmacokinetics): the chronesthesy (rhythmic changes in susceptibility of target biosystem to this drug), and the chronergy (the drug-integrated overall effects). One of the aims of chronopharmacology is solving problems of drug optimization. Knowledge of those administration times coinciding with best effectiveness or tolerance is required to optimize both timing(s) and dosage(s) of a medication. Illustrative examples of both experimental and clinical investigative chronopharmacology are corticosteroids and anticancerous agents.</p>","PeriodicalId":9217,"journal":{"name":"Biomedicine / [publiee pour l'A.A.I.C.I.G.]","volume":"34 4","pages":"171-8"},"PeriodicalIF":0.0,"publicationDate":"1981-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18215479","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}
