Iterium (Rilmenidine Dihydrogen Phosphate)

Rilmenidine selectively stimulates imidazoline I1 receptors in the brainstem. This activation reduces sympathetic nervous system activity, leading to decreased peripheral vascular resistance and lower cardiac output, which together result in a reduction of systemic blood pressure.

The appropriate dose of Iterium is determined by the prescribing healthcare professional based on the individual’s clinical condition, response to therapy, and any concomitant medications. Patients should follow the prescriber’s instructions and not adjust the dose on their own.

Safety data for rilmenidine in pregnancy and lactation are limited. It is generally recommended to avoid use unless the potential benefit justifies the potential risk to the fetus or infant. Women who are pregnant, planning pregnancy, or breastfeeding should discuss alternatives with their healthcare provider.

To request Iterium, 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 and any necessary import documentation.

Iterium belongs to the imidazoline receptor agonist class, which lowers blood pressure by reducing sympathetic outflow. Unlike beta‑blockers or ACE inhibitors, it does not block adrenergic receptors or inhibit the renin‑angiotensin system, offering an alternative mechanism that can be combined with those classes for additive effect.

Iterium tablets should be stored at room temperature, below 25 °C, in the original packaging to protect them from moisture and light. Keep the product out of reach of children and do not use it after the expiry date printed on the label.

Iterium is taken orally as a tablet. The tablet should be swallowed whole with a glass of water, preferably at the same time each day. Patients should not crush, chew, or split the tablet unless specifically instructed by a healthcare professional.

The most serious adverse events reported with rilmenidine include severe hypotension, which can lead to fainting or falls, significant elevations in liver enzymes indicating possible hepatic injury, and allergic reactions such as rash, angioedema, or anaphylaxis that require immediate medical attention.

Iterium should be avoided in patients with known hypersensitivity to rilmenidine or any excipients, in individuals with severe hypotension, and in those taking monoamine oxidase inhibitors. Caution is also advised for patients with significant renal or hepatic impairment, and the drug should be used only under medical supervision.
