Fluvoxamine, sold under the brand name Luvox among others, is an antidepressant of the selective serotonin reuptake inhibitor (SSRI) class. [8] It is primarily used to treat major depressive disorder and, perhaps more-especially, obsessive–compulsive disorder (OCD), [9] but is also used to treat anxiety disorders [10] such as panic disorder, social anxiety disorder, and post-traumatic stress ...
Examples of sympathomimetic effects include increases in heart rate, force of cardiac contraction, and blood pressure. [1] The primary endogenous agonists of the sympathetic nervous system are the catecholamines (i.e., epinephrine [adrenaline], norepinephrine [noradrenaline], and dopamine ), which function as both neurotransmitters and hormones .
Cardiotonic agents, also known as cardiac inotropes or stimulants, have a positive impact on the myocardium (muscular layer of the heart) by enhancing its contractility. Unlike general inotropes, these agents exhibit a higher level of specificity as they selectively target the myocardium.
Activation of β 2 receptors induces smooth muscle relaxation in the lungs, gastrointestinal tract, uterus, and various blood vessels. Increased heart rate and heart muscle contraction are associated with the β1 receptors; however, β 2 cause vasodilation in the myocardium. [citation needed] β3 receptors are mainly located in adipose tissue. [5]
Common signs of an Adderall withdrawal are feeling tired, mentally “foggy,” taking the drug despite knowing it’s causing harm or needing larger doses to feel the effects. fizkes/istockphoto ...
The adverse side effects of amphetamine are many and varied, and the amount of amphetamine used is the primary factor in determining the likelihood and severity of adverse effects. [ 29 ] [ 41 ] Amphetamine products such as Adderall , Dexedrine, and their generic equivalents are currently approved by the U.S. FDA for long-term therapeutic use.
Numerous studies have demonstrated the effectiveness of drugs such as Adderall (a mixture of salts of amphetamine and dextroamphetamine) in controlling symptoms associated with ADHD. Due to their availability and fast-acting effects, substituted amphetamines are prime candidates for abuse.
An increase in sympathetic stimulation to the heart increases contractility and heart rate. An increase in contractility tends to increase stroke volume and thus a secondary increase in preload. An increase in preload results in an increased force of contraction by Starling's law of the heart; this does not require a change in contractility.
