Study Notes
Adrenergic Drugs Classification
-
Norepinephrine: A1, A2, B1 agonist; induces vasoconstriction.
-
Epinephrine: A1, A2, B1, B2 agonist; used for vasoconstriction, treating acute asthma and anaphylactic shock.
-
Isoproterenol: B1, B2 agonist; primarily prescribed for asthma management.
-
Phenylephrine: A1 agonist; serves as a nasal decongestant and causes vasoconstriction.
-
Clonidine: A2 agonist; acts as an antihypertensive to lower blood pressure.
-
Dobutamine: B1 agonist; enhances cardiac output and stroke volume.
-
Terbutaline: B2 agonist; commonly used for respiratory conditions.
-
Metaproterenol: B2 agonist; indicated for asthma treatment.
-
Albuterol: B2 agonist; utilized for acute asthma attacks.
-
Salmeterol: B2 agonist; effective for managing nocturnal asthma.
-
Formoterol: B2 agonist; indicated for asthma treatment, providing long-lasting effects.
-
Bitolterol: B2 agonist; used for asthma management.
-
Ritodrine: B2 agonist; indicated for the prevention of premature labor.
-
Indacaterol: B2 agonist; treatment for Chronic Obstructive Pulmonary Disease (COPD).
-
Mirabegron: B3 agonist; used for treating overactive bladder.
Adrenergic Antagonists
-
Phenoxybenzamine: A1, A2 antagonist; reduces peripheral resistance and blood pressure.
-
Prazosin: A1 antagonist; functions as an antihypertensive agent to lower blood pressure.
-
Tamsulosin: A1 antagonist; used primarily for treating benign prostatic hyperplasia (BPH).
-
Terazosin: A1 antagonist; beneficial in BPH with minimal impact on blood pressure.
-
Propranolol: B1, B2 antagonist; decreases heart rate and is widely used for various cardiac conditions.
-
Atenolol: B1 antagonist; primarily lowers heart rate.
-
Acebutolol: B1 antagonist; reduces heart rate impacts.
-
Metoprolol: B1 antagonist; commonly prescribed for lowering heart rate.
-
Pindolol: B1, B2 antagonist; decreases heart rate and utilized in managing hypertension.
-
Nadalol: B1, B2 antagonist; functions to lower heart rate effectively.
-
Timolol: B1, B2 antagonist; reduces heart rate and used in ophthalmic preparations.
-
Esmolol: B1 antagonist; ultra-short-acting, effective for acute treatment and crisis situations.
-
Labetalol: B1, B2 antagonist; decreases heart rate and aids in managing hypertension.
-
Carvedilol: B1, B2 antagonist; effective in lowering heart rate.
-
Nebivolol: B1 antagonist; reduces heart rate and improves overall cardiovascular health.
-
Ephedrine: A1, B1, B2 antagonist; increases blood pressure and improves breathing in emergencies.
