adrenergic drugs produce which effect
Side effects and adverse effects: Side effects can occur when the drug dosage in increased or the drug is nonselective causing more responses to occur than are desired. Anorexia, nausea, vomiting, nervousness, tremors, agitation, headache, pallor, insomnia, syncope, dizziness and restlessness are common side effects. alpha 1 agonists. -drugs, including NE and EPI, that produce contraction of smooth muscle by stimulating alpha 1 receptors. -NE is considered to be the parent compound for the alpha 1 drugs. -alpha adrenergic drugs have chemical structures and produce effects that are almost identical to those of NE. ***vasodilation. Sympathomimetic drug. Chemical structures of the catecholamines. Sympathomimetic drugs (also known as adrenergic drugs and adrenergic amines) are stimulant compounds which mimic the effects of endogenous agonists of the sympathetic nervous system. Integrate pharmacodynamic principles to understand the actions of drugs that interact with the adrenergic receptors and how these interactions are relevant to dental practice. 2. Understand the effects of epinephrine and norepinephrine on the cardiovascular system. The effects of the cholinergic drugs are to produce the same effects as stimulation of the parasympathetic nervous system. These effects include slowing of the heartbeat, increases in normal secretions including the digestive acids of the stomach, saliva and tears. Understand the pharmacologic actions and therapeutic actions of drugs that act at the beta1 and beta2 -adrenergic receptors as well as the alpha1 -adrenergic receptor. 3. Know the mechanism of action and effects of amphetamine and cocaine. Cholinergic drugs. Actions and uses. Cholinergic drugs are medications that produce the same effects as the parasympathetic nervous system, especially imitating acetylcholine. Acetylcholine is the most common neurohormone of the parasympathetic nervous system, it is responsible for the everyday work of the body. ADRENERGIC BLOCKERS. Actions and uses:Adrenergic blockers are drugs that block the effects of adrenergic neurotransmitters. They act as antagonists to adrenergic agonists by blocking the alpha- and beta-receptor sites. The educational goal is to understand the uses in dental practice of drugs that interact at the adrenergic receptors as well as toxicities that could occur as a result of these interactions. In addition, dental patients are likely to be taking drugs that act at these receptors. Adrenergic drugs stimulate the sympathetic nervous system by mimicking sympathetic neurotransmitters such as norepinephrine and epinephrine. They act on adrenergic receptor sites located in the cells of muscles, such as the heart, bronchiole walls, GI tract, urinary bladder, and ciliary muscle of the eye.
Endogenous agonists of the sympathetic nervous system.
