Zymfecard, XL-30 (Nifedipine) Tablets

What is Nifedipine 30mg Extended Release?

Nifedipine 30mg Extended Release is a once-daily, long-acting calcium channel blocker — one of the most widely prescribed and clinically proven medicines for managing high blood pressure (hypertension) and chronic chest pain (angina). Its extended-release technology delivers a steady, controlled amount of medication over a full 24 hours, maintaining consistent blood pressure control from morning to night without the peaks and troughs associated with older immediate-release formulations.

Nifedipine is a dihydropyridine calcium channel blocker approved for the treatment of chronic stable angina and hypertension. Extended-release preparations have been shown to have a sustained 24-hour antihypertensive effect and fewer adverse effects. 

Nifedipine 30mg ER represents the standard initiation dose — the strength most doctors start patients on before adjusting upward if needed. It is a practical, well-tolerated entry point into Nifedipine therapy, with a safety and efficacy record spanning several decades of clinical use worldwide.

What is Nifedipine 30mg ER Used For?

Primary Approved Indications:

• High Blood Pressure (Hypertension) — Nifedipine is used alone or in combination with other drugs to treat high blood pressure. Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems. 
• Chronic Stable Angina (Chest Pain Prevention) — This medication is also used for certain types of chest pain (angina). It may help increase your ability to exercise and decrease the frequency of chest pain attacks. It should not be used to treat chest pain when it occurs. Use other medications (such as sublingual nitroglycerin) to relieve attacks of chest pain as directed by your doctor. 
• Vasospastic Angina (Prinzmetal's Angina) — Nifedipine is particularly effective for vasospastic angina — a form of chest pain caused by sudden spasm of the coronary arteries rather than fixed blockages. Its powerful vasodilatory action directly counteracts coronary artery spasm.

What Conditions Does Nifedipine 30mg Help Protect Against?

By effectively controlling blood pressure and preventing coronary artery spasm, Nifedipine 30mg ER helps reduce the risk of:

• Stroke — caused by sustained high pressure bursting or blocking brain blood vessels
• Heart Attack — caused by narrowed and spasming coronary arteries
• Kidney Failure — caused by persistently elevated blood pressure damaging delicate kidney filtration vessels
• Vision Loss — caused by hypertensive retinopathy damaging retinal blood vessels
• Angina attacks — allowing patients to exercise more and live more actively

How to Take Nifedipine 30mg ER

• Dosage must be adjusted according to each patient's needs. Therapy for either hypertension or angina should be initiated with 30 or 60mg once daily. The 30mg tablet is therefore the standard, recommended starting dose for most patients. 
• Take once daily — at the same time each day for maximum consistency.
• Extended-release formulations of Nifedipine should be taken on an empty stomach. Always follow your doctor's specific instructions on timing relative to meals. 
• Take this medication by mouth with or without food as directed by your doctor, usually once daily. Swallow the tablets whole. Do not crush or chew the tablets — doing so can release all of the drug at once, increasing the risk of side effects. 
• Extended-release preparations are available in 30, 60, and 90mg tablets. Dosage adjustments should ideally occur at 7 to 14-day intervals. 
• Use this medication regularly to get the most benefit from it. To help you remember, take it at the same time each day. 
• Never stop Nifedipine suddenly — if discontinuation is necessary, the dosage should be decreased gradually with close physician supervision, as abrupt stopping can worsen blood pressure and trigger angina.

Common Side Effects

• Ankle and foot swelling (peripheral oedema) 
• Flushing 
• Headache 
• Dizziness or lightheadedness 
• Nausea 

Seek immediate medical attention if you experience:

• Chest pain, pressure, tightness, or squeezing — especially if new or worsening
• Severe shortness of breath or difficulty breathing
• Rapid, pounding, or very irregular heartbeat
• Significant swelling of the hands, legs, or feet that develops quickly
• Severe dizziness, fainting, or near-collapse
• Signs of allergic reaction: hives, severe rash, difficulty breathing, facial swelling
