Isoprenaline Macure (Isoprenaline Hydrochloride)

The drug binds to both β1 and β2 adrenergic receptors. In the heart, β1 activation raises cyclic AMP levels, increasing calcium entry into cardiac cells, which speeds up pacemaker activity and strengthens contraction. In the lungs, β2 stimulation raises cyclic AMP in airway smooth muscle, causing relaxation and bronchodilation.

Dosing is individualized and must be determined by a qualified prescriber based on the patient’s clinical condition, weight, and response. The healthcare professional will set the infusion rate, titrate as needed, and monitor vital signs to achieve the desired therapeutic effect while minimizing adverse reactions.

Safety data for Isoprenaline in pregnancy and lactation are limited. It should only be used when the potential benefit to the mother outweighs any possible risk to the fetus or infant. Women who are pregnant, planning pregnancy, or breastfeeding should discuss risks with their healthcare provider.

Isoprenaline differs from agents such as dopamine or epinephrine by providing strong β‑adrenergic stimulation with relatively less α‑mediated vasoconstriction. This results in pronounced heart‑rate acceleration and bronchodilation but may cause fewer increases in systemic vascular resistance compared with epinephrine. Choice of agent depends on the specific clinical scenario and physician judgment.

The product should be stored at room temperature, below 25 °C, in its original packaging to protect it from moisture and light. Do not freeze the solution. Before use, inspect the vial for particulate matter or discoloration and discard if any abnormalities are observed.

Isoprenaline is given intravenously, typically as a controlled infusion. The medication is diluted in an appropriate carrier solution according to the prescriber’s instructions and administered via a calibrated infusion pump or syringe driver, allowing precise titration to achieve the desired hemodynamic or bronchodilatory response.

Serious adverse events include life‑threatening arrhythmias, myocardial ischemia, severe hypotension, pulmonary edema, and anaphylactic reactions. Patients should be continuously monitored for changes in heart rhythm, blood pressure, and respiratory status, and immediate medical intervention should be available if any of these complications arise.

Isoprenaline is contraindicated in patients with severe aortic stenosis, uncontrolled hypertension, recent myocardial infarction, or known hypersensitivity to the drug or its excipients. Caution is also advised in individuals with hyperthyroidism, severe heart failure, or those taking non‑selective beta‑blockers, as the therapeutic effect may be blunted.
