Monosordil (Isosorbide Mononitrate)

Isosorbide mononitrate is converted in the body to nitric oxide, a potent vasodilator. Nitric oxide activates guanylate cyclase, increasing cyclic GMP levels in vascular smooth muscle, which relaxes the vessels, lowers blood pressure, and reduces the workload on the heart, thereby decreasing myocardial oxygen consumption.

The dose of Monosordil is individualized by the prescribing clinician based on the patient’s clinical condition, response, and tolerance. Healthcare professionals determine the appropriate strength and dosing schedule, which may be adjusted over time to achieve optimal symptom control.

Safety data for isosorbide mononitrate in pregnancy and lactation are limited. It should only be used if the potential benefit justifies any possible risk to the fetus or infant. Women who are pregnant, planning to become pregnant, or breastfeeding should discuss alternatives and risks with their healthcare provider.

To request Monosordil, 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 any cold‑chain requirements), and necessary import documentation.

Monosordil belongs to the organic nitrate class, offering a once‑daily oral option that provides steady nitric‑oxide release. Compared with short‑acting nitrates, it has a longer half‑life and fewer dosing fluctuations, but like all nitrates it may cause tolerance over time. Alternatives such as beta‑blockers or calcium‑channel blockers work via different mechanisms and may be preferred based on patient comorbidities.

Monosordil tablets should be stored at room temperature, below 25 °C, in the original packaging to protect them from moisture and light. Keep the container tightly closed and out of reach of children. No refrigeration is required for this oral formulation.

Monosordil is taken orally, usually with a glass of water. It can be taken with or without food, but patients should follow the prescribing clinician’s instructions regarding timing and whether to maintain a consistent daily schedule to ensure stable plasma levels.

The most serious risks include severe hypotension, which can lead to fainting or syncope, and rare allergic reactions such as rash, angioedema, or anaphylaxis. Patients should seek immediate medical attention if they experience sudden dizziness, fainting, chest pain, or signs of an allergic response.

Monosordil should be avoided in patients with known hypersensitivity to isosorbide mononitrate or any other organic nitrates, those who have taken other nitrate medications within the past 24 hours, and individuals with severe anemia, closed‑angle glaucoma, or uncontrolled hypotension. Clinicians must assess each patient’s medical history before prescribing.
