Sorbitrate (Isosorbide Dinitrate) is a medication used primarily to prevent chest pain (angina) in patients with heart conditions. It works by relaxing blood vessels, improving blood flow to the heart. Sorbitrate 5mg is not typically available over the counter and requires a prescription in most countries, including the USA, due to its specific medical use and potential side effects. For those in the USA, Sorbitrate can be purchased through licensed pharmacies with a valid prescription. Always consult with a healthcare provider before using Sorbitrate.
