Albuterol [PROAIR, Proventil, Ventolin HFA] Drug Class: RESPIRATORY SYSTEM DRUGS --> Bronchodilators --> Beta2 Adrenergic Receptor Agonists --> Short-Acting Beta2 Adrenergic Receptor Agonist Pharmacological Class: Short-Acting Beta2 Adrenergic Receptor Agonist Other Drugs in Class: levalbuterol [Xopenex] Mechanism of Action: Relaxes bronchial smooth muscle by action on beta2-receptors with little effect on heart rate Labeled and Unlabeled Use: Treatment or prevention of broncho...

Adrenergic Agonist epinephrine: activates the SNS by increasing BP (alpha1), HR (beta1) and promotes bronchioldilation (beta2) SNS response from adrenergic agonists agents that activate adrenergic receptors in the sympathetic nervous system causing o Dilates pupils, increases intraocular pressure o Dilates bronchioles o Increases heart rate and strength of contractions o Constricts blood vessels and increases BP o Reduces GI secretions and motility o Relaxes bladder and decreases urina...

A patient asks his provider to explain what drug tolerance means. The provider responds by telling the patient that when tolerance occurs, it means the patient __________.Answer - may need increased amounts of the drug over time When tolerance develops, a dose increase may be needed because a decreased response may occur with prolonged use A group of nursing students asks a nurse to explain the blood-brain barrier. The nurse would be correct to say that the blood-brain barrier ________...

adrenergic agonist - ANSWERa drug that stimulates the adrenergic receptors of the sympathetic nervous system, either directly (by reacting with receptor sites) or indirectly (by increasing norepinephrine levels) alpha-agonist - ANSWERspecifically stimulating to the alpha-receptors within the sympathetic nervous system, causing body responses seen when the alpha-receptors are stimulated beta-agonist - ANSWERspecifically stimulating to the beta-receptors within the sympathetic nervous system...

Side effects of Positive Pressure ventilation - 1. Increased intrathoracic pressure leads to decreased venous return to the heart, decreasing stroke volume, and CO Two types of ventilators - 1. Negative pressure ventilators- i.e iron lung 2. Positive pressure ventilators: hospital bedside ventilators, use positive pressure to force air into the lungs by reversing normal breathing patterns. Stimulates both adrenergic and dopaminergic receptors, lower doses are mainly dopaminergic stimulatin...
