[Delta sleep-inducing peptide as a modulator of mediators acting on the heart]
Abstract:
Experiments on 51 isolated rabbit hearts have documented, that delta sleep-inducing peptide (6 X 10(-6) M/l) has a modulating effect on the mediators influencing the heart. This peptide enhances negative chronotropic effect of acetylcholine (1 X 10(-6) M/l) and decreases positive chronotropic effect of noradrenaline (1 X 10(-6) M/l). Such effect may be one of mechanisms of changes in the extracardiac regulation on the heart influenced by this peptide.

Sedatives and Hypnotics: Overview
Sedative-hypnotics are categorized into barbiturates, benzodiazepines (BZDs), and non-benzodiazepines or Z-drugs. These drugs work by suppressing central nervous system activity, and this suppression is dose-dependent. Older sedative medications, like barbiturates, follow a linear curve in...

Sedatives and Hypnotics Drugs: Miscellaneous Agents
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...
