Gynipral (Hexoprenaline Sulfate)

Gynipral is employed in clinical practice for conditions that benefit from uterine smooth‑muscle relaxation or bronchodilation. It is typically used under medical supervision in acute care settings.

• Tocolysis for the management of preterm labor to delay delivery.
• Adjunct therapy for bronchospasm in asthma when rapid bronchodilation is required.
• Situations requiring short‑term uterine relaxation during obstetric procedures.
• Emergency treatment of severe uterine hyperactivity.
• Off‑label use may occur in specialized respiratory care under physician direction.

Side effects of Gynipral vary in frequency and severity. Patients should be monitored for both common and serious reactions.

Common

• Tremor or shaking, especially in the hands.
• Palpitations or increased heart rate.
• Headache.
• Nausea or mild gastrointestinal discomfort.
• Transient flushing or feeling of warmth.

Serious

• Significant arrhythmias or cardiac rhythm disturbances.
• Severe hypotension or hypertension.
• Pulmonary edema.
• Allergic reactions such as rash, urticaria, or anaphylaxis.
• Hyperglycemia in susceptible individuals.

Gynipral should be used with caution, and several safety considerations are recommended before and during therapy.

• Assess cardiovascular status; avoid use in patients with uncontrolled arrhythmias.
• Monitor blood pressure and heart rate continuously during infusion.
• Use cautiously in patients with diabetes, as it may affect glucose levels.
• Evaluate for a history of thyroid disease, as beta‑2 agonists can influence thyroid function.
• Ensure appropriate fetal monitoring when administered during pregnancy.
• Adjust dose in patients with severe renal or hepatic impairment.
• Discontinue promptly if serious adverse reactions occur.

Potential drug interactions with Gynipral can influence its safety and effectiveness. Clinicians should review concomitant medications.

Avoid

• Non‑selective beta‑blockers, which may diminish the bronchodilator effect.
• Monoamine oxidase inhibitors (MAOIs) that could increase the risk of hypertensive crisis.
• Other potent vasodilators that may exacerbate hypotension.

Use with caution

• Diuretics, as they may potentiate hypokalemia.
• Antidiabetic agents, due to possible hyperglycemic effects.
• Other beta‑2 agonists, which could increase the risk of tachycardia.
• Calcium channel blockers, which may affect cardiac conduction when combined.
