4.2 Drug Indication

Isoprenaline is indicated to treat mild or transient episodes of heart block not requiring electric shock or pacemakers, serious episodes of heart block and Adams-Stokes attacks not caused by ventricular tachycardia or fibrillation, and bronchospasm during anesthesia. Isoprenaline is also indicated for cases of cardiac arrest until preferable treatments like electric shock and pacemakers are available. Isoprenaline is also indicated as an adjunct therapy to fluid and electrolyte replacement therapy in hypovolemic shock, septic shock, hypoperfusion, congestive heart failure, and cardiogenic shock.


FDA Label


5 Pharmacology and Biochemistry
5.1 Pharmacology

Isoprenaline is a non-selective beta adrenergic receptor agonist used in a number of indications for the heart, as well as bronchospasm in anesthesia. Isoprenaline has a short duration of action as it is rapidly cleared, and a wide therapeutic index. Patients should be counselled regarding the risks of isoprenaline in the treatment of cardiogenic shock following myocardial infarction, paradoxical worsening of heart block, or precipitation of Adams-Stokes attacks.


5.2 MeSH Pharmacological Classification

Adrenergic beta-Agonists

Drugs that selectively bind to and activate beta-adrenergic receptors. (See all compounds classified as Adrenergic beta-Agonists.)


Bronchodilator Agents

Agents that cause an increase in the expansion of a bronchus or bronchial tubes. (See all compounds classified as Bronchodilator Agents.)


Sympathomimetics

Drugs that mimic the effects of stimulating postganglionic adrenergic sympathetic nerves. Included here are drugs that directly stimulate adrenergic receptors and drugs that act indirectly by provoking the release of adrenergic transmitters. (See all compounds classified as Sympathomimetics.)


Cardiotonic Agents

Agents that have a strengthening effect on the heart or that can increase cardiac output. They may be CARDIAC GLYCOSIDES; SYMPATHOMIMETICS; or other drugs. They are used after MYOCARDIAL INFARCT; CARDIAC SURGICAL PROCEDURES; in SHOCK; or in congestive heart failure (HEART FAILURE). (See all compounds classified as Cardiotonic Agents.)

5.5 Absorption, Distribution and Excretion

Absorption

Data regarding absorption kinetics of isoprenaline are not readily available.


Route of Elimination

Isoprenaline is 12.2-27.0% recovered in the feces and 59.1-106.8% recovered in the urine after 48 hours. The majority of the recovered dose in the urine is conjugated isoprenaline, with 6.5-16.2% free isoprenaline, and 2.6-11.4% 3-O-methylisoprenaline and conjugates.


Volume of Distribution

In pediatric patients, the volume of distribution was 216 57 mL/kg.


Clearance

In pediatric patients, the clearance of isoprenaline was 42.5 5.0 mL/kg/min.


5.6 Metabolism/Metabolites

Isoprenaline is predominantly metabolized to glucuronide conjugates. Isoprenaline can also be O-methylated by catechol O-methyltransferase to the metabolite 3-O-methylisoprenaline, which can also be further glucuronidated.


5.7 Biological Half-Life

The half life of intravenous isoprenaline is 2.5-5 minutes. Oral isoprenaline has a half life of 40 minutes.


5.8 Mechanism of Action

Isoprenaline is a non-selective beta adrenergic receptor agonist. Agonism of beta-1 and beta-2 adrenergic receptors causes the alpha subunit of G-protein coupled receptors to exchange GMP for GTP, activating them, and allowing the alpha subunit to dissociate from the beta and gamma subunits. Dissociation of the alpha subunit activates adenylate cyclase, converting ATP to cyclic AMP. Cyclic AMP activates protein kinase A (PKA), which phosphorylates cardiac L-type calcium channels such as Cav1.2. These channels depolarize cells by inward active transport of calcium ions. Agonism of beta-1 adrenergic receptors lead to increased strength of contractility, conduction of nerve impulses, speed of relaxation, and rate in the heart. Agonism of beta-2 adrenergic receptors leads to glycogenolysis in the liver, glucagon release from the pancreas, and activation of the renin-angiotensin-aldosterone system. In the alveoli, agonism of beta-2 adrenergic receptors, activates similar pathways to the heart, however the end result is regulation of sodium channels, the cystic fibrosis transmembrane conductance regulator (CFTR), and sodium potassium ATPase. PKA phosphorylates scaffolding proteins and sodium channels, increasing the number of sodium channels on the apical side of alveolar cells and increasing active transport of sodium ions into cells. Agonism of beta-2 adrenergic receptors can also increase chloride ion transport across CFTR. Together, these actions lead to passive transport of water out of the alveoli, and the clearance of alveolar fluid.
