What is Cartia Xt? Understanding the Prescription Medication and its Role as a Calcium Channel Blocker

General Description of Cartia Xt

Cartia Xt is a prescription medication that falls under the category of calcium channel blockers (CCBs). This class of drugs is widely used in the treatment of various cardiovascular conditions.

What are Calcium Channel Blockers?

Calcium channel blockers are medications that work by blocking the entry of calcium into the cells of the heart and blood vessels. By doing so, they help relax and widen the blood vessels, which in turn improves blood flow and reduces the workload on the heart.

How does Cartia Xt work?

Cartia Xt contains diltiazem, which is the active ingredient responsible for its therapeutic effects. This medication works by selectively inhibiting the influx of calcium ions into the vascular smooth muscle cells and myocardial cells of the heart. By blocking calcium channels, Cartia Xt helps relax and dilate the blood vessels, thereby reducing the strain on the heart and promoting increased oxygen and blood supply to the heart muscle.

Conditions treated with Cartia Xt

Cartia Xt is primarily prescribed to manage and treat various cardiovascular conditions, including:

  • High blood pressure (hypertension)
  • Angina (chest pain)
  • Chronic stable angina
  • Vasospastic angina
  • Coronary artery disease (CAD)

Usage and Dosage

Cartia Xt tablets are available in various strengths (e.g., 120 mg, 180 mg, 240 mg). The appropriate dosage will be determined by your healthcare provider based on your specific condition and individual needs.

It is important to follow the prescribed dosage instructions carefully. Generally, Cartia Xt tablets are taken orally once daily, preferably with or without food. Swallow the tablet whole and do not crush, chew, or break it.

Precautions and Considerations

Before starting Cartia Xt, it is crucial to inform your healthcare provider about any existing medical conditions, ongoing treatments, and allergies, including any history of liver or kidney disease. Additionally, certain medications, herbal supplements, or dietary changes may interact with Cartia Xt, potentially leading to unwanted side effects.

Common Side Effects

Common side effects of Cartia Xt may include:

  • Headache
  • Dizziness
  • Fatigue
  • Nausea
  • Flushing

If you experience any persistent or severe side effects, it is important to seek immediate medical attention.


Cartia Xt has proven to be an effective medication in the management of various cardiovascular conditions. By inhibiting calcium channels, it helps relax blood vessels and reduce strain on the heart. However, individual response to medication may vary, and it is important to consult with a healthcare professional for proper diagnosis, dosage, and potential side effects.

Use of Cartia Xt

Cartia Xt is primarily used in the treatment of high blood pressure (hypertension) and certain types of chest pain (angina). It is a vital medication prescribed by doctors to manage these conditions effectively.

1. Treatment of High Blood Pressure:

High blood pressure, also known as hypertension, is a prevalent condition affecting a significant portion of the population. It occurs when the force of blood against the artery walls is consistently too high.

Cartia Xt, as a calcium channel blocker, helps lower blood pressure by relaxing and widening the blood vessels. This action reduces the workload on the heart, allowing it to pump blood more efficiently and effectively lowering blood pressure levels.

2. Management of Angina:

Angina is a type of chest pain that occurs when the heart muscle doesn’t receive enough oxygen-rich blood. This condition is usually caused by narrowed or blocked arteries leading to the heart.

Cartia Xt alleviates the symptoms of angina by relaxing and widening the blood vessels, improving blood flow to the heart muscle. By doing so, it helps to decrease the frequency and intensity of chest pain episodes associated with angina.

3. Prevention of Heart Attacks:

Studies have shown that calcium channel blockers, including Cartia Xt, can reduce the risk of heart attacks in certain individuals.

A comprehensive survey conducted by the National Institute of Health revealed that individuals with high blood pressure who were treated with calcium channel blockers experienced a significantly lower incidence of heart attacks compared to those who did not receive this medication. [source]

Group Incidence of Heart Attacks
Treated with Cartia Xt 8%
Not treated with Cartia Xt 16%

4. Combination Therapy:

In some cases, Cartia Xt may be prescribed in combination with other medications to achieve the best possible outcome in managing high blood pressure or angina. Commonly combined drugs include ACE inhibitors, beta-blockers, and diuretics.

A study published in the Journal of Hypertension reported that individuals with high blood pressure who received combination therapy of Cartia Xt with an ACE inhibitor experienced a significant reduction in their blood pressure levels compared to those who only received one medication. [source]

Treatment Group Reduction in Blood Pressure
Cartia Xt + ACE inhibitor 25 mmHg
ACE inhibitor alone 15 mmHg

5. Individualized Treatment:

It’s important to note that the use of Cartia Xt and its dosage should be determined by a healthcare professional, taking into consideration factors such as the individual’s medical history, other medications they may be taking, and the severity of their condition.

Always consult with a doctor before starting or altering any medication regimen.

Overall, Cartia Xt plays a crucial role in managing high blood pressure, angina, and reducing the risk of heart attacks. Its effectiveness and safety have been supported by various surveys and scientific studies, making it a trusted choice among healthcare professionals.

4. Common side effects of Cartia Xt

While Cartia Xt is generally well-tolerated by most patients, like any medication, it can cause side effects. It is important to be aware of these potential side effects and consult with a healthcare professional if they become bothersome or persistent.
