Noradrenaline (Norepinephrine) Kalceks (Norepinephrine)

Norepinephrine stimulates alpha‑1 and alpha‑2 adrenergic receptors, causing strong vasoconstriction that increases systemic vascular resistance. Its modest beta‑1 activity also supports heart contractility, together resulting in higher arterial pressure and improved tissue perfusion.

The dose of norepinephrine is individualized by the prescribing clinician based on the patient’s hemodynamic status, target blood pressure, and response to therapy. Dosing is typically expressed in micrograms per minute and adjusted continuously during infusion.

The safety of norepinephrine in pregnancy and lactation has not been established. It should only be used if the potential benefit justifies the potential risk to the fetus or infant, and this decision must be made by the treating physician.

To place an order, submit an enquiry on the product page at gnhindia.com, specifying the required quantity. GNH India works with hospitals, pharmacies and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details (including cold‑chain where required) and necessary import documentation.

Norepinephrine is often preferred as a first‑line vasopressor because of its potent alpha‑1 mediated vasoconstriction and relatively lower risk of tachyarrhythmias compared with agents like dopamine. Phenylephrine provides pure alpha activity, while epinephrine adds stronger beta effects, which may be less desirable in certain shock states.

The product must be stored refrigerated at 2‑8 °C, protected from light, and must never be frozen or shaken. Keep the vial in its original packaging until use to maintain stability and potency.

Norepinephrine is supplied as a sterile solution for injection and is administered intravenously, usually via a central venous catheter. The infusion is started at a low rate and titrated to achieve the desired blood pressure, with continuous hemodynamic monitoring.

Serious risks include myocardial ischemia, severe hypertension, and tissue necrosis at the infusion site due to extravasation. Prompt recognition of these events and immediate intervention, such as adjusting the infusion rate or stopping the drug, are essential to prevent lasting damage.

Norepinephrine is contraindicated in patients with known hypersensitivity to the drug or its excipients, and it should be used with extreme caution in individuals with severe peripheral vascular disease, uncontrolled hypertension, or recent myocardial infarction.
