Presenting peer-reviewed papers on basic chronobiology and medical chronobiology, this multidisciplinary journal serves as the leading forum for communication in biological rhythm investigations. It is the only journal which regularly features articles on rhythm-dependencies in the kinetics and dynamics of medications-chronopharmacology- and chronotherapeutics-optimization of drug effects and safety by timing to rhythm determinants. Chronobiology International publishes groundbreaking articles on genetic and molecular mechanisms of biological timekeeping, melatonin and pineal gland rhythms, as well as on the chronobiology and chronotherapy of cardiovascular, pulmonary, ulcer and other diseases.
