💓 Diltiazem 180mg Capsule: Heart Health and Blood Pressure Control
🧬 What Is Diltiazem 180mg?
Diltiazem 180mg is an extended-release (ER) calcium channel blocker (CCB) used primarily to treat:
-
Hypertension (high blood pressure)
-
Angina (chronic chest pain)
-
Certain heart rhythm disorders such as atrial fibrillation and atrial flutter
It works by relaxing the muscles of the heart and blood vessels, reducing the heart rate and allowing easier blood flow, which helps reduce blood pressure and control chest pain.
💊 How to Use
-
Dosage: Typically one capsule daily, but dosage can vary depending on the condition and patient response.
-
Form: Extended-release capsule; must be swallowed whole.
-
Administration: Can be taken with or without food. Take at the same time each day for consistency.
-
Missed Dose: Take as soon as remembered unless close to the next dose. Do not double up.
🔬 Active Ingredient & Mechanism
-
Diltiazem Hydrochloride (180mg):
A non-dihydropyridine calcium channel blocker that:-
Blocks calcium from entering the heart and vascular smooth muscle cells.
-
Lowers heart rate
-
Reduces myocardial oxygen demand
-
Decreases blood pressure
-
This dual action makes it suitable for cardiovascular conditions involving both rhythm and pressure control.
😊 Common Side Effects
-
Dizziness or lightheadedness
-
Swelling in hands or feet (edema)
-
Flushing
-
Headache
-
Nausea
-
Constipation
-
Tiredness or weakness
Most side effects are mild and lessen over time with continued use.
⚠️ Serious Side Effects
Seek medical attention if you experience:
-
Very slow heartbeat (bradycardia)
-
Heart failure symptoms (e.g., swelling, fatigue, breathing difficulty)
-
Severe hypotension (fainting, confusion)
-
Liver problems (jaundice, dark urine, abdominal pain)
-
Severe allergic reaction (rash, hives, trouble breathing)
🧪 Monitoring & Follow-Up
-
Blood pressure and heart rate – monitored frequently during dose titration
-
ECG (Electrocardiogram) – especially if used for arrhythmia
-
Liver function tests (LFTs) – if symptoms suggest liver involvement
-
Kidney function – periodically, especially in elderly or those with comorbidities
⚠️ Warnings & Precautions
-
Do not stop abruptly – can cause rebound chest pain or worsening of arrhythmias.
-
Avoid grapefruit juice – it interferes with Diltiazem metabolism and may raise blood levels dangerously.
-
Not recommended in patients with:
-
Severe hypotension
-
Heart block (unless pacemaker is present)
-
Decompensated heart failure
-
-
Caution in elderly patients – higher sensitivity to cardiovascular effects
-
Pregnancy/Breastfeeding – Use only if clearly needed and prescribed by a doctor
Drug interactions:
-
Additive effects with beta-blockers
-
May increase levels of digoxin, cyclosporine, and statins
-
Risk of enhanced blood pressure lowering when used with other antihypertensives
