What Experts Say

Cardiologists in Pakistan prescribe Sustac Tablet 6.4mg as a long acting nitrate for patients with recurring angina caused by narrowed coronary arteries. Glyceryl Trinitrate relaxes vascular smooth muscle, so more oxygen rich blood reaches the heart during physical or emotional stress.

Doctors emphasize regular dosing rather than occasional use, since Sustac is meant to prevent angina episodes before they start. Patients are advised never to stop this medicine suddenly, because abrupt withdrawal after long term nitrate therapy can trigger rebound chest pain or worsen underlying heart disease. Any dose changes should happen gradually and only under medical supervision.

Experts warn that Sustac Tablet 6.4mg should never be combined with sildenafil or other PDE5 inhibitor medicines, since this combination can cause a dangerous drop in blood pressure. Physicians stress getting a proper cardiac evaluation before starting or adjusting nitrate therapy.

How to use Sustac Tablet 6.4mg?

• Take Sustac Tablet 6.4mg exactly as prescribed, usually one or two tablets up to three times a day.
• Swallow the tablet whole with a full glass of water.
• Do not crush, break, or chew this tablet, since that destroys its sustained release action.

• If a dose is missed, take it as soon as remembered. Do not double the next dose.

Drug Interactions

• Sildenafil And Other PDE5 Inhibitors: This is a critical, dangerous interaction. Combining Sustac with sildenafil, tadalafil, or vardenafil can cause a severe and sudden fall in blood pressure.
• Other Blood Pressure Medicines: Taking Sustac with antihypertensives, diuretics, or beta blockers can add to blood pressure lowering effects.
• Alcohol: Alcohol increases the risk of dizziness and low blood pressure when combined with this medicine.
• Other Nitrates: Combining with other nitrate medicines or nitrate based ointments raises the risk of excessive hypotension.
• Heparin: High dose intravenous nitrates may reduce the blood thinning effect of heparin in hospital settings.

Risks and warnings

• Low Blood Pressure: Sustac can cause a sharp drop in blood pressure, especially when standing up quickly, leading to dizziness or fainting.
• PDE5 Inhibitor Interaction: Never take this medicine with sildenafil, tadalafil, or similar erectile dysfunction drugs, since the combination can cause severe, life threatening hypotension.
• Head Injury Or Brain Bleeding: Avoid use in patients with recent head trauma or cerebral hemorrhage, since nitrates can raise pressure inside the skull.
• Severe Anemia: Use with caution in patients with marked anemia, as nitrates may further reduce oxygen delivery in these cases.
• Glaucoma: Patients with narrow angle glaucoma should use this medicine only under close medical supervision.
• Alcohol Use: Drinking alcohol while on Sustac can intensify blood pressure lowering effects and increase dizziness.
• Pregnancy And Breastfeeding: Safety data is limited, so this medicine should only be used in pregnancy or lactation if a doctor considers it necessary.
• Tolerance: Long term continuous use may reduce the medicine's effectiveness, so doctors often plan short nitrate free intervals.
