Lesson 13 Flashcards
Are autonomic nervous sytem drugs that stimulate the adrenergic receptors
Adrenergic agonists
Adrenergic agonist are classified into three:
Alpha and Beta adrenergic agonist
Alpha-specific adrenergic agonist
Beta-specific adrenergic agonist
An eye condition characterized by increased in intraocular pressure
Glaucoma
This agonist help in dilating the pupils
Alpha adrenergic agonists
A complication caused by acute blood loss that can significantly alter the functions of the organs and tissues
Shock
A hypersensitivity reaction to specific triggers characterized by inflammatory reactions and bronchospasm
Asthma
Adrenergic agonist is also called as
Sympathomimetic
Example drugs of the alpha and beta adrenergic agonist
Dopamine
Epinephrine
A naturally occuring catecholamine
Dopamine
Synthetic catecholamines indicated for treatment of heart failure
Dobutamine
Ephedrine
Stimules release of norepinephrine from nerve endings
Ephedrine
Drugs that bind primarily to alpha receptors rather than beta receptors
Alpha-specific adrenergic agonists
Oral drugs used to treat orthostatic hypertension
Midodrine
Drugs that bind primarily to beta receptors rather than alpha receptors
Beta-specific adrenergic agonist
Referred to as symphatolytics
Adrenergic antagonists
They lyse, or block, the effects of the sympatetic nervous system
Adrenergic antagonists
Primarily used to treat cardiac related conditions
Non-selective adrenergic Antagonist
Five andrenergic antagonist
Non-selective adrenergic antagonist
Non-selective alpha adrenergic antagonist
Non-selective beta adrenergic antagonist
Selective alpha adrenergic antagonist
Selective beta adrenergic antagonist
It can improve urine flow in male patients and are used as treatment for benign hypertrophy
Selective alpha1-receptor adrenergic antagonists
Used to treat cv and prevent infarction after MI
Non-selective beta adrenergic antagonist
More advantageous than non-selective beta blockers, allow bronchodilation
Non-selective beta adrenergic antagonist
It block all the receptors (alpha and beta)
Non-selective adrenergic blocking agents
Drugs with specific affinity for alpha-receptor sites
Non-selective alpha-adrenergic blocking agents
Drugs that have affinity for alpha1-receptor sites
Alpha-selective adrenergic blocking agents
Drugs that block the beta-receptors within the CNS
Non-selective beta andrenergic blocking agents
Drugs that do not block the beta receptors responsible for bronchodilation
Beta-selective adrenergic blocking agents
In non-selective alpha-adrenergic blocking agents, the drugs used is
Phentolamine
