Generic Cartia Xt Information

Introduction

Cartia Xt is a cardiovascular medicine marketed for the management of hypertension and angina. The tablet contains the active compound diltiazem HCl, a calcium‑channel blocker belonging to the blood‑pressure and cardiovascular therapeutic groups. In Hong Kong, elevated blood pressure and ischemic heart disease remain leading causes of morbidity, and clinicians frequently prescribe diltiazem‑based products to achieve rate control, relieve anginal pain, and lower systemic vascular resistance. Cartia Xt is manufactured by a multinational pharmaceutical company (specific manufacturer details may vary by market) and is also available in several brand formulations such as Cartia, Cardizem, and Diltiazem HCl SR.

What is Cartia Xt?

Cartia Xt is a tablet formulation that delivers diltiazem HCl, an L‑type calcium‑channel antagonist. It is classified as a non‑dihydropyridine calcium‑channel blocker. The drug was originally developed in the 197s by Cardiotonic Laboratories and later licensed worldwide. In most territories the product is produced under the Cartia brand name, but identical generic versions are marketed by multiple manufacturers. Our online pharmacy offers this medication as a cost‑effective alternative that meets the same pharmaco‑technical specifications as the original brand products.

How Cartia Xt Works

Diltiazem blocks voltage‑gated L‑type calcium channels in vascular smooth muscle and cardiac myocytes. By inhibiting calcium influx:

• Vasodilation occurs in peripheral arterioles, reducing systemic vascular resistance and consequently lowering arterial blood pressure.
• Coronary artery dilation improves myocardial oxygen delivery, alleviating ischemic chest pain.
• Negative chronotropic and dromotropic effects decrease heart‑rate and slow atrioventricular (AV) nodal conduction, which is useful for rate control in atrial fibrillation and for terminating supraventricular tachycardias.

The onset of action for immediate‑release tablets is within 30–60 minutes, whereas extended‑release formulations achieve therapeutic plasma concentrations over a 12‑ to 24‑hour period. Diltiazem is metabolized primarily by hepatic CYP3A4 enzymes, with an elimination half‑life of roughly 3–5 hours for the immediate‑release form and 6–8 hours for the prolonged‑release preparation.

Conditions Treated with Cartia Xt

• Hypertension (essential) – Diltiazem lowers systolic and diastolic pressures by reducing peripheral vascular tone. In Hong Kong, the prevalence of hypertension is estimated at 27 % among adults, making effective oral agents essential for cardiovascular risk reduction.
• Chronic stable angina pectoris – Coronary vasodilation and decreased myocardial oxygen demand relieve exertional chest discomfort.
• Atrial fibrillation (rate control) – The drug’s AV‑node blocking properties slow ventricular response without inducing significant negative inotropy.
• Supraventricular tachycardia (off‑label) – By prolonging AV‑node refractory period, diltiazem can terminate re‑entrant tachyarrhythmias.

These indications are approved by major regulatory agencies (e.g., US FDA, EMA, Hong Kong’s Department of Health) and are supported by robust clinical trial data.

Patient Groups Most Likely to Benefit

• Adults with stage 1 or stage 2 hypertension who have not achieved target blood pressure with monotherapy or who require a medication with a favorable metabolic profile.
• Patients with effort‑induced angina who are intolerant to β‑blockers (e.g., due to asthma) or nitrates (e.g., due to severe hypotension).
• Elderly individuals who need modest heart‑rate reduction without pronounced negative inotropic effects.
• Patients with atrial fibrillation where a rate‑controlling agent is needed but β‑blockers are contraindicated.

Contra‑indications include severe hypotension (systolic BP < 90 mmHg), second‑ or third‑degree AV block without a pacemaker, sick‑sinus syndrome, and decompensated heart failure. Caution is advised in hepatic impairment, severe renal insufficiency, and in patients taking strong CYP3A4 inhibitors.

Risks, Side Effects, and Interactions

Common

• Headache
• Flushing or warmth sensation
• Peripheral edema (ankle/foot)
• Dizziness or light‑headedness, especially on standing (orthostatic effect)
• Fatigue or mild weakness
• Nausea, abdominal discomfort

Rare

• Photosensitivity reactions
• Skin rash or pruritus
• Elevated liver transaminases (ALT/AST)
• Taste disturbances (dysgeusia)

Serious

• Bradycardia (heart rate < 50 bpm)
• Second‑ or third‑degree AV block
• Exacerbation of heart failure (pulmonary edema, dyspnea)
• Severe hypotension leading to syncope
• Myocardial infarction or unstable angina (in rare cases)

Clinically Relevant Drug–Drug Interactions

• CYP3A4 inhibitors (ketoconazole, erythromycin, clarithromycin, ritonavir) → increase diltiazem plasma levels, heightening risk of bradycardia and hypotension.
• CYP3A4 inducers (rifampin, carbamazepine, phenytoin) → reduce efficacy.
• Other antihypertensives (ACE inhibitors, ARBs, diuretics) → additive blood‑pressure lowering; monitor for orthostatic hypotension.
• β‑blockers (metoprolol, atenolol) → additive AV‑node slowing; consider dose reduction.
• Digoxin → increased serum digoxin concentrations; monitor levels.
• Grapefruit juice → inhibits intestinal CYP3A4, raising diltiazem concentrations.

Patients should disclose all prescription, over‑the‑counter, and herbal products to their healthcare provider.

Practical Use: Dosing, Missed Dose, Overdose

• Standard dosing (adults):

  • Immediate‑release tablets: 30 mg three times daily, titrated up to a maximum of 120 mg three times daily based on blood‑pressure response and tolerability.
  • Extended‑release tablets: 120 mg once daily, with possible escalation to 180 mg or 240 mg once daily. Some clinicians use 240 mg twice daily for refractory hypertension, but this is off‑label.

• Missed dose: If a dose is forgotten and more than 2 hours remain before the next scheduled dose, take the missed tablet promptly. If the next dose is imminent, skip the missed tablet and resume the regular schedule. Do not double the dose.

• Overdose: Symptoms may include profound hypotension, severe bradycardia, cardiac conduction abnormalities, and syncope. Immediate medical attention is required. Management includes gastric decontamination with activated charcoal (if within 1 hour of ingestion), intravenous fluids, vasopressors, and atropine for symptomatic bradycardia.

• Precautions:

  • Take tablets with or without food; avoid grapefruit juice.
  • Alcohol may potentiate hypotensive effects; limit intake.
  • Monitor liver function tests periodically, especially in patients with pre‑existing hepatic disease.
  • Adjust dose in severe renal impairment (eGFR < 30 mL/min/1.73 m²) due to reduced clearance of metabolites.
