Serotonin involvement in lisuride-induced mounting and in sleep
Pharmacopsychiatry
|March 1, 1985
Summary
Lisuride-induced mounting in rats, linked to altered neurotransmission, serves as a model for identifying drugs affecting monoaminergic systems. This research explores the role of serotonin and dopamine in behavior and sleep regulation.
Area of Science:
- Neuropharmacology
- Behavioral Neuroscience
Background:
- Mounting behavior in rats can be induced by drugs affecting neurotransmitter levels.
- Serotonin (5-HT) and dopamine (DA) neurotransmission are implicated in regulating behavior and the sleep-wake cycle.
Purpose of the Study:
- To propose lisuride-induced mounting as a behavioral model for detecting drugs that modulate monoaminergic mechanisms.
- To investigate the role of specific neurotransmitters in drug-induced behaviors and sleep.
Main Methods:
- Induction of mounting behavior in rats using various drugs (p-CPA, 5,7-dihydroxytryptamine, L-DOPA, lisuride).
- Analysis of the combined effects of decreased serotonin and increased dopamine on behavior.
- Evaluation of the potential of lisuride-induced mounting as a screening model for pharmacologically active compounds.
Main Results:
- Drug-induced mounting behavior correlates with a decrease in serotonin and an increase in dopamine neurotransmission.
- Lisuride-induced mounting shows promise as a model for identifying drugs targeting serotonin reuptake and monoamine oxidase A.
Conclusions:
- Lisuride-induced mounting provides a valuable behavioral model for drug discovery targeting monoaminergic pathways.
- Serotonin plays a significant role in the sleep-wake cycle, though other neuromodulators are also involved.

01:28Antidepressant Drugs: Tricyclics, SSRIs, and SNRIs
Tricyclic Antidepressants (TCAs), including Desipramine (Norpramin), Imipramine (Tofranil), Clomipramine (Anafranil), and Amitriptyline (Elavil), inhibit serotonin and norepinephrine reuptake and also block other receptors. They are used for depression, pain conditions, and insomnia. Common adverse effects include anticholinergic effects, sedation, orthostatic hypotension, and weight gain. They have a narrow therapeutic window and so require plasma-level monitoring. Abrupt discontinuation can...
01:23Antidepressant Drugs: MAOIs and Other Agents
Atypical antidepressants, including bupropion (Wellbutrin), mirtazapine (Remeron), nefazodone (Serzone), trazodone (Desyrel), and vilazodone (Viibryd), offer unique mechanisms of action. Bupropion weakly inhibits dopamine and norepinephrine reuptake, aiding depression treatment and smoking cessation, with a low risk of sexual dysfunction. Mirtazapine enhances serotonin and norepinephrine neurotransmission, leading to sedation, increased appetite, and weight gain. As a result, it helps treat...
01:23Sedatives and Hypnotics: Overview
Sedatives are drugs that alleviate anxiety, while hypnotics induce sleep. Both classes of medication suppress neuronal activity, leading to a calming effect for sedatives and facilitating sleep for hypnotics.
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...

01:19Management of Insomnia
The sleep cycle, an integral part of human health, consists of several stages with distinct characteristics and functions. It begins with a transition from wakefulness to sleep, known as the light sleep phase, followed by the restorative deep sleep phase, essential for physical recovery and growth. The cycle concludes with the Rapid Eye Movement (REM) phase, characterized by high brain activity and vivid dreaming. Insomnia, a prevalent sleep disorder, involves difficulty falling asleep, staying...

Sedatives and hypnotics encompass a wide range of substances, each with its unique mechanism of action, uses, and potential adverse effects.
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...

01:23Drugs Affecting GI Tract Motility: Serotonin Receptor Agonists
Serotonin, a crucial neurotransmitter synthesized by enterochromaffin cells, plays a cardinal role in regulating gastrointestinal (GI) motility. With over 90% of the body's total serotonin in the GI tract, its influence on digestive processes is profound. Serotonin is swiftly released upon various stimuli, such as food boluses or certain drugs, triggering intrinsic sensory neurons in the myenteric plexus and extrinsic vagal and spinal sensory neurons. This leads to the activation of the...
