Nitro Pohl (Glyceryl Trinitrate)

Glyceryl trinitrate, the active ingredient in Nitro Pohl, is a nitrate vasodilator presented as an intravenous solution for intravenous use. It provides rapid relief of coronary artery spasm and reduces cardiac preload and afterload in acute angina, heart failure and hypertensive crises.

GNH India supplies Nitro Pohl as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide, with manufacturing provenance from the European Union.

Indications & Clinical Uses

  • Nitro Pohl (glyceryl trinitrate) is employed in cardiovascular emergencies where rapid vasodilation is required.
  • Acute angina pectoris: rapid relief of chest pain by dilating coronary arteries.
  • Acute heart failure: reduction of preload and afterload to improve cardiac output.
  • Hypertensive emergencies: prompt lowering of systemic blood pressure through venous and arterial dilation.

How It Works

  • Glyceryl trinitrate is enzymatically converted to nitric oxide within vascular smooth‑muscle cells. The released NO activates soluble guanylate cyclase, raising intracellular cyclic GMP levels, which relaxes smooth muscle, dilates veins and arteries, reduces preload and afterload, and alleviates coronary artery spasm. The vasodilatory effect appears within minutes after intravenous administration and is dose‑dependent.

Side Effects

Intravenous glyceryl trinitrate may cause a range of adverse reactions, varying from mild to severe.

Common Side Effects

  • Headache: throbbing headache due to cerebral vasodilation.
  • Flushing: facial or upper‑body flushing.
  • Hypotension: transient drop in blood pressure.
  • Tachycardia: reflex increase in heart rate.

Serious or Rare Side Effects

  • Methemoglobinemia: elevated methemoglobin causing cyanosis.
  • Severe hypotension: profound blood pressure fall leading to syncope.
  • Cardiac arrhythmias: new‑onset arrhythmias.
  • Allergic reaction: anaphylaxis or severe skin reactions.

Precautions & Warnings

  • When using Nitro Pohl, clinicians should observe specific safety measures to minimise risk.
  • Monitoring: continuous blood pressure and heart‑rate monitoring during infusion.
  • Titration: adjust infusion rate based on hemodynamic response.
  • Concomitant nitrates: avoid concurrent use to prevent excessive hypotension.
  • Phosphodiesterase‑5 inhibitors: contraindicated due to risk of severe hypotension.
  • Cardiovascular instability: use with caution in severe aortic stenosis or recent myocardial infarction.
  • Store at ambient temperature: keep in original container, protect from light and moisture, and do not freeze.

Avoid Interactions

Glyceryl trinitrate interacts with several drug classes; awareness of these interactions helps prevent adverse events.

Major Interactions (Avoid)

  • Phosphodiesterase‑5 inhibitors (e.g., sildenafil, tadalafil): can cause profound hypotension.
  • Other nitrates or nitric‑oxide donors: additive vasodilatory effect leading to severe hypotension.
  • Sodium nitroprusside: synergistic vasodilation.

Moderate Interactions (Monitor Closely)

  • Antihypertensives (beta‑blockers, ACE inhibitors): may enhance blood‑pressure lowering.
  • Diuretics: can increase risk of hypotension.
  • Alcohol: may potentiate vasodilatory effect.

Frequently Asked Questions

Nitro Pohl is an intravenous formulation of glyceryl trinitrate used in hospital settings to treat acute angina pectoris, acute heart failure, and hypertensive emergencies. By rapidly dilating coronary and systemic vessels, it relieves chest pain, reduces cardiac workload, and lowers dangerously high blood pressure.

Glyceryl trinitrate is converted in the body to nitric oxide, a potent vasodilator. Nitric oxide activates soluble guanylate cyclase, increasing cyclic GMP within smooth‑muscle cells. Elevated cyclic GMP causes relaxation of vascular smooth muscle, producing venous and arterial dilation, reduced preload and afterload, and relief of coronary artery spasm.

The specific dose and infusion rate of Nitro Pohl are determined by the prescribing clinician based on the patient’s condition, hemodynamic status, and response to therapy. Dosing is individualized and should follow institutional protocols and the product’s prescribing information.

The safety of glyceryl trinitrate in pregnancy and lactation has not been definitively established. It is generally classified as a category where benefits must outweigh potential risks, and use is reserved for situations where alternative treatments are unsuitable. Clinicians should evaluate each case carefully.

To order Nitro Pohl, 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.

Nitro Pohl contains glyceryl trinitrate, which is chemically identical to nitroglycerin and shares the same mechanism of nitric‑oxide donation. The main differences lie in formulation and regulatory status; Nitro Pohl is supplied as a sterile intravenous solution meeting EU GMP standards, whereas other products may be available in different concentrations or dosage forms.

Store Nitro Pohl at ambient temperature, preferably below 25 °C, in its original packaging. Protect the solution from direct light, moisture and extreme temperature fluctuations. Do not freeze or shake the vial, and ensure that any opened container is used within the time frame recommended by the manufacturer.

Nitro Pohl is administered intravenously by a qualified healthcare professional. The solution is typically infused through a calibrated infusion set, with the rate adjusted according to the patient’s blood‑pressure response and clinical condition. Continuous monitoring of vital signs is essential throughout the infusion.

The most serious risks include severe hypotension that can lead to syncope or organ hypoperfusion, methemoglobinemia causing impaired oxygen delivery, and life‑threatening cardiac arrhythmias. Prompt recognition and management of these events are critical, and the drug should be discontinued if they occur.

Nitro Pohl should be avoided in patients with known hypersensitivity to glyceryl trinitrate or other nitrates, those who have taken phosphodiesterase‑5 inhibitors within the past 24‑48 hours, and individuals with severe aortic stenosis or uncontrolled hypotension. Contraindications must be confirmed before initiating therapy.
