Description
Isosorbide dinitrate 10 mg tablets (UK generic) are used to prevent and treat angina pectoris (chest pain caused by heart disease).
Primary Uses:
– Prevention and management of angina pectoris.
Drug Class:
– Nitrate vasodilator, an antianginal agent.
General Mechanism of Action:
– Isosorbide dinitrate works by relaxing and dilating blood vessels, which reduces the heart’s workload and improves blood flow to the heart muscle, thereby relieving or preventing chest pain.
Common Forms:
– Oral tablets, including 10 mg strength.
Dosage Instructions:
– Typically taken two to three times daily with careful attention to creating a nitrate-free interval of about 14 hours to reduce tolerance.
– The exact dosage and frequency depend on the patient’s condition and response to treatment.
– Tablets should be swallowed with water and can be taken with or without food.
Side Effects, Contraindications, or Interactions:
– Common side effects include headache, dizziness, flushing, low blood pressure, and lightheadedness.
– Contraindicated in patients with severe anemia, increased intracranial pressure, hypotension, or hypersensitivity to nitrates.
– Should not be used in combination with phosphodiesterase inhibitors (such as sildenafil) due to risk of severe hypotension.
– Use caution in patients with heart failure or hypotension.
– May interact with other blood pressure-lowering medications.
Medical supervision is important for safe and effective use.
