Isordil Titradose
Isordil Titradose (Isosorbide Dinitrate) is a nitrate medication used primarily to prevent and treat angina pectoris (chest pain) associated with coronary artery disease. It helps to relieve angina by dilating blood vessels, reducing the heart's workload, and improving blood flow to the heart muscle.

Comprehensive Drug Guide
How Does Isordil Titradose Work?
Isosorbide dinitrate works by relaxing the smooth muscles in blood vessels, leading to vasodilation. This action decreases preload (the amount of blood returning to the heart), which reduces myocardial oxygen demand and helps relieve angina symptoms.
Common Dosages
- Extended-release tablets: Common dosages include 30 mg, 60 mg, or 120 mg.
Typical Dosing
- The usual starting dose is 30 mg taken orally two or three times daily. The dosage may be adjusted based on individual response and tolerability, with a maximum recommended dose of 240 mg per day.
Typical Dosing
FDA Approved Indications
- Prevention and treatment of angina pectoris due to coronary artery disease.
Who Shouldn't Take Isordil Titradose?
- Known hypersensitivity to isosorbide dinitrate or any components of the formulation
- Severe anemia
- Hypotension (low blood pressure)
- Increased intracranial pressure (e.g., due to head trauma or hemorrhage)
Advice From The Pharmacist
- Patients should be advised to take Isordil Titradose as prescribed and not to crush or chew the tablets, as this can affect the extended-release mechanism.
- Encourage patients to maintain a consistent dosing schedule to avoid fluctuations in blood pressure and angina control.
- Inform patients about the possibility of headaches, a common side effect, and recommend that they report persistent or severe headaches to their healthcare provider.
