Question 1

What is Hydralazine?

Accepted Answer

Hydralazine is a medication classified as a peripheral vasodilator and antihypertensive. It works by relaxing the muscles in the walls of the blood vessels, allowing them to widen.

This process helps blood flow more easily and reduces the pressure within the cardiovascular system. By expanding the blood vessels, the medication helps to regulate blood pressure levels.

Question 2

What is Hydralazine used for?

Accepted Answer

Hydralazine is used to treat hypertension and heart failure .

Question 3

How does Hydralazine work?

Accepted Answer

Mechanism of Action

Hydralazine belongs to a class of medications known as peripheral vasodilators. It works by acting directly on the smooth muscles in the walls of the blood vessels, causing them to relax and expand.

When these blood vessels widen, it creates more space for blood to circulate. This process has several effects on the cardiovascular system:

Reduced Resistance: It lowers the resistance that blood faces as it travels through the arteries.

Lower Blood Pressure: By reducing resistance, the overall pressure within the circulatory system decreases.

Decreased Heart Workload: Because the blood vessels are wider, the heart does not have to pump as hard to move blood through the body.

Although the exact chemical process that causes the muscles to relax is not fully established, the medication primarily targets the arteries and arterioles rather than the veins.

Question 8

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

Accepted Answer

How to Take Hydralazine

Hydralazine is available as a tablet to be taken by mouth. It is usually taken several times a day, often four times daily. It is important to follow the specific schedule provided by your healthcare provider and to take the medication at the same times every day.

You may take hydralazine with or without food. However, you should choose one way and stick to it consistently so that the medicine is absorbed into your body the same way each time.

Missed Dose

If you miss a dose, take it as soon as you remember. If it is almost time for your next dose, skip the missed dose and continue with your regular schedule. Do not take two doses at once to make up for a missed one.

General Instructions

Take this medication exactly as directed by your doctor.

Do not stop taking hydralazine without consulting your healthcare provider, even if you feel well.

Your doctor may occasionally change your dose to ensure you get the best results.

Question 9

Is Hydralazine safe during pregnancy and breastfeeding?

Accepted Answer

Pregnancy

There are no adequate and well-controlled studies of hydralazine use in pregnant women. Research in animals has shown that high doses of the medication may cause birth defects, such as cleft palate, in certain species. Because of these findings, healthcare providers typically only prescribe hydralazine during pregnancy if the potential benefit justifies the potential risk to the developing baby.

Breastfeeding

Hydralazine has been shown to pass into breast milk in small amounts. While there are no specific reports of adverse effects on nursing infants, the safety of using this medication while breastfeeding is not fully established. It is important to discuss the risks and benefits with a healthcare provider if you are breastfeeding or planning to breastfeed while taking this medication.

Question 10

What forms and strengths does Hydralazine come in?

Accepted Answer

Available Forms

Hydralazine is primarily available in the following forms:

Oral Tablet: This form is taken by mouth and is the most common method for long-term management.

Injectable Solution: This form is intended for intramuscular or intravenous administration. It is typically administered by a healthcare professional in a clinical or hospital setting.

Combination Products

Hydralazine is also available in combination with other medications in a single oral tablet. These combination products may include:

Hydralazine and hydrochlorothiazide (a diuretic).

Hydralazine and isosorbide dinitrate (a nitrate).

Question 11

What is the FDA approval status of Hydralazine?

Accepted Answer

FDA Approval and Indications

Hydralazine is FDA-approved for the treatment of essential hypertension, also known as high blood pressure. It may be used alone or in combination with other medications to help lower blood pressure. Additionally, the FDA has approved fixed-dose combinations of hydralazine and isosorbide dinitrate for the treatment of heart failure in specific patient populations, particularly to improve survival and reduce hospitalizations in Black patients.

Safety Communications

The FDA monitors the safety of hydralazine through the FDA Adverse Event Reporting System (FAERS). In 2016, the agency identified a potential safety signal regarding drug-induced lupus erythematosus and vasculitis (inflammation of the blood vessels) associated with hydralazine use. These conditions occur when the immune system mistakenly attacks healthy tissues or blood vessels.

Pharmacogenomic Information

The FDA-approved labeling for hydralazine includes information about how genetic variations can affect how the body processes the medication. Specifically, the rate at which a person's liver metabolizes the drug, known as acetylation, can influence safety. Individuals who are slow acetylators may have higher levels of the drug in their system, which can increase the risk of developing drug-induced lupus.

Regulatory Requirements

Hydralazine is available as a generic prescription medication in oral tablet and injectable forms. It does not currently require a Risk Evaluation and Mitigation Strategy (REMS) program, and it does not carry a Boxed Warning, which is the FDA's most serious category of warning for approved drugs.

Question 12

What should I know about Hydralazine and cost?

Accepted Answer

Generic Availability

Hydralazine is available as a generic drug. Generic medications are typically less expensive than brand-name versions because they do not require the same initial research and marketing costs.

Factors Influencing Cost

The amount you pay for hydralazine can be affected by several factors:

Insurance Coverage: Most insurance plans, including Medicare Part D, cover generic hydralazine. Your specific out-of-pocket cost will depend on your plan's copayments, coinsurance, and deductible requirements.

Pharmacy Selection: Prices for the same prescription can vary between different retail pharmacies, mail-order services, and local clinics.

Prescription Details: The total cost may change based on the dosage strength and the number of tablets prescribed for each refill.

Because prices can fluctuate, patients are encouraged to check with their insurance provider or pharmacist to determine their specific costs. Some pharmacies may also offer discount programs for generic medications.
