Question 1

What is Imdur?

Accepted Answer

Imdur is a long-acting nitrate medication that works by relaxing and widening the blood vessels. This process, known as vasodilation , allows blood to flow more easily through the body and reduces the overall workload on the heart.

Question 2

What is Imdur used for?

Accepted Answer

Imdur is used to treat angina pectoris .

Question 3

How does Imdur work?

Accepted Answer

Mechanism of Action

Imdur works by relaxing the smooth muscles found in the walls of blood vessels. This relaxation causes the blood vessels to widen, a process called vasodilation. When the vessels are wider, it is easier for blood to circulate, which reduces the overall workload on the heart.

Preventing Angina

By widening the arteries and veins, Imdur helps ensure that the heart muscle receives a steady supply of oxygen-rich blood. This helps prevent angina, which is chest pain that occurs when the heart muscle is strained or lacks sufficient oxygen.

Because Imdur is an extended-release tablet, it releases the medication slowly into the bloodstream over time. This makes it effective for preventing future episodes of chest pain, but it is not intended to treat a sudden attack of angina.

Question 4

What are the active ingredients in Imdur?

Accepted Answer

The active ingredient in Imdur is Isosorbide mononitrate .

Question 5

Always consult with a healthcare professional about potential side effects.

Question 6

What drug class is Imdur?

Accepted Answer

Question 7

What is the dosage of Imdur and how do I take it?

Accepted Answer

How to Take Imdur

Imdur is generally taken once a day, often in the morning upon waking. You can take this medication with or without food, but it is important to be consistent. Taking the tablet at the same time each day helps maintain a steady level of medicine in your system.

These tablets are extended-release and must be swallowed whole with liquid. Do not crush or chew the tablet, as doing so can interfere with the slow-release mechanism and release all the medication at once.

Missed Dose

If you miss a dose, take it as soon as you remember. If it is nearly time for your next dose, skip the missed dose and return to your regular schedule. Do not take extra medicine to make up for a missed dose.

Question 8

Is Imdur safe during pregnancy and breastfeeding?

Accepted Answer

Pregnancy

There are no adequate and well-controlled studies of Imdur in pregnant women. Animal reproduction studies using high doses of isosorbide mononitrate did not show evidence of harm to the developing fetus. However, because animal studies are not always predictive of human response, this medication should be used during pregnancy only if clearly needed and under the guidance of a healthcare provider.

Breastfeeding

It is not known whether isosorbide mononitrate passes into human breast milk. Because many medications are excreted in breast milk, healthcare providers typically advise caution when Imdur is administered to a nursing woman. If you are breastfeeding or planning to breastfeed, discuss the potential risks and benefits with your doctor to determine the best course of action for you and your infant.

Question 9

What forms and strengths does Imdur come in?

Accepted Answer

Imdur is supplied in the following form for oral administration:

Extended-release tablet: This formulation is designed to release the medication slowly into the bloodstream over an extended period.

These tablets are generally intended to be swallowed whole to maintain the extended-release properties. Some versions of the tablet may be scored, which allows them to be broken in half if a partial dose is required, but they should not be crushed or chewed.

Question 10

What is the FDA approval status of Imdur?

Accepted Answer

FDA Approval and Indications

Imdur is approved by the U.S. Food and Drug Administration (FDA) for the prevention of angina pectoris due to coronary artery disease. As an extended-release formulation of isosorbide mononitrate, it is designed to be taken on a regular schedule to help reduce the frequency and severity of chest pain episodes over time.

Limitations of Use

The FDA-approved labeling specifies that Imdur is not intended for the immediate relief of acute angina attacks. Because the medication is released slowly into the bloodstream, it does not work quickly enough to stop chest pain that has already started. Patients are typically advised to use a fast-acting nitrate medication for sudden symptoms.

Safety Warnings and Contraindications

While Imdur does not have a boxed warning or a Risk Evaluation and Mitigation Strategy (REMS) program, the FDA-approved labeling includes a major contraindication regarding its use with certain other drugs. It must not be used in combination with phosphodiesterase inhibitors, such as sildenafil, tadalafil, or vardenafil. Co-administration of these medications can lead to a dangerous and potentially life-threatening drop in blood pressure.

Question 11

What should I know about Imdur and cost?

Accepted Answer

Generic Availability

Imdur is available as a generic drug called isosorbide mononitrate. Generic medications are typically much less expensive than brand-name versions. Most insurance plans and Medicare Part D cover the generic form of this medication, which can significantly reduce out-of-pocket expenses.

Factors Influencing Price

Several variables can affect the final price of the medication:

Insurance Coverage: Your specific plan determines your copay or coinsurance amount based on their drug formulary.

Pharmacy Selection: Prices can vary between different retail pharmacies and mail-order services.

Prescription Quantity: Buying a 90-day supply may sometimes offer a lower per-dose cost compared to a 30-day supply.

If you have concerns about the cost of Imdur, you may want to discuss generic alternatives or patient assistance programs with your healthcare provider or pharmacist.
