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.
