What is Isosorbide mononitrate ER 30 mg TB?
Isosorbide mononitrate extended-release 30 mg tablets (often written as “isosorbide mononit er 30 mg TB”) are a long-acting form of isosorbide mononitrate. It’s used to prevent angina (chest pain) by relaxing blood vessels and improving blood flow to the heart.
What is it used for?
This medication is commonly prescribed for prevention of angina attacks. It is not typically used to treat an angina attack that’s already happening (that’s usually done with a fast-acting nitrate such as nitroglycerin).
How is ER 30 mg usually taken?
Because it’s “ER” (extended-release), dosing is usually done on a schedule meant to provide steady effect through the day. The exact instructions depend on the prescription and your condition, so it’s important to follow your label or clinician’s directions.
What are common side effects people report?
Common side effects can include headache, dizziness, lightheadedness, flushing, and low blood pressure. If you get severe dizziness, fainting, or symptoms of very low blood pressure, you should seek medical care.
What important drug interactions should be avoided?
Nitrates like isosorbide mononitrate can interact with certain medicines used for erectile dysfunction (for example, sildenafil, tadalafil, vardenafil, and similar drugs), which can cause dangerous drops in blood pressure. Tell your prescriber/pharmacist about all medicines you take.
Can you take it with alcohol or other blood-pressure medicines?
Alcohol and other blood-pressure–lowering medicines can increase the chance of dizziness or fainting. If you’re on antihypertensives or have low blood pressure, discuss this with your clinician.
What should patients watch for regarding tolerance?
Like other nitrates, regular use can sometimes lead to reduced effect over time (“tolerance”). Prescribers often use dosing schedules that include nitrate-free periods when appropriate.
Is there a brand-name version, and is it covered by patents?
