Angina
Angina
Angina is chest discomfort caused by reduced blood flow to heart muscle. This category focuses on therapies that prevent episodes and relieve acute attacks. You can compare brand and generic names, dosage forms like sublingual tablets, capsules, and extended-release tablets, and a range of strengths. Stock and pack sizes may change without notice as suppliers update listings. We provide options with US shipping from Canada, alongside links to related conditions and learning resources to support safe browsing.Angina OverviewThis syndrome reflects an imbalance between oxygen supply and demand in the myocardium. It often presents as pressure, tightness, or burning behind the breastbone that may spread to the jaw, back, or arm. Episodes can be brought on by exertion, cold exposure, or heavy meals, and they usually resolve with rest or short-acting nitrate therapy.Clinicians classify presentations as stable, worsening, or sudden-onset patterns that require urgent evaluation. Risk factors include atherosclerosis, high blood pressure, diabetes, and tobacco use. Pharmacologic options aim to reduce myocardial workload, widen coronary vessels, and prevent recurrent ischemia. Common classes include nitrates, beta-blockers, and calcium channel blockers. Some agents act on late sodium current or reduce vasospasm to improve exercise tolerance and symptom control.What’s in This CategoryThis category contains medicines used to prevent attacks and to treat angina symptoms during a sudden episode. Short-acting nitrates are available as sublingual tablets for fast relief. Long-acting nitrates come as once-daily or twice-daily tablets and capsules. Calcium channel blockers and beta-blockers provide preventive control, with options tailored to heart rate, blood pressure, and comorbidities. A late sodium current inhibitor offers symptom reduction for patients who need an alternative or add-on.Examples include Nitroglycerin tablets for on-demand relief during an episode. For chronic prevention, Ranolazine can be considered when first-line drugs are not tolerated or insufficient. You can browse dosage forms such as extended-release tablets, immediate-release tablets, and sublingual tablets, then compare strengths and typical dosing intervals. Always review labeling for maximum daily doses and interactions before selecting a product to discuss with a clinician.How to ChooseSelection depends on diagnosis, symptom pattern, and comorbid conditions. Patients with new or changing chest pain patterns require urgent assessment; this may indicate unstable angina. For preventive therapy, consider heart rate, blood pressure, and exercise tolerance, as these factors guide whether a beta-blocker, calcium channel blocker, or other agent fits best. For rapid relief, short-acting nitrates are commonly used, with clear instructions on use and repeat dosing.Compare once-daily extended-release options like Nifedipine XR if you prefer simpler regimens. If rate control is needed or palpitations occur, Verapamil may be considered in appropriate patients. Check storage and handling rules, especially for sublingual tablets, which often require a tightly closed original container. Verify drug interactions involving CYP3A substrates and strong inhibitors, and review nitrate-free intervals to limit tolerance with long-acting nitrates.Avoid doubling doses after missed preventive tablets.Do not combine phosphodiesterase inhibitors with nitrates.Do not exceed labeled repeat doses for acute relief.Popular OptionsMany patients use daily calcium channel blockers to reduce exercise-induced chest discomfort. Amlodipine is a once-daily option that helps lower blood pressure and decrease episodes linked to exertion or cold weather. It suits patients who need vasodilation without excessive heart rate slowing. When rate control and blood pressure reduction both matter, choices are tailored to individual vitals and symptoms.Long-acting nitrates provide steady vasodilation through the day. Isosorbide Mononitrate offers extended-release dosing with a planned nitrate-free interval to reduce tolerance. Beta-blockers can be used when heart rate reduction is desired; options vary by cardioselectivity and dosing profile. In high-risk cases or changing patterns, clinicians will consider Atenolol or other agents within a broader plan for unstable angina treatment directed by guidelines.Related Conditions & UsesChest discomfort exists on a spectrum, and some presentations require urgent care. Learn how clinicians differentiate sudden changes in pattern, duration, and triggers under Unstable Angina. Stable exertional patterns often relate to fixed coronary narrowing and predictable triggers. Broader risk reduction includes lipid management, smoking cessation, and blood pressure control as part of long-term cardiovascular care.If you want to understand artery narrowing and ischemia, explore Coronary Artery Disease.

Frequently Asked Questions
Which products are listed in this angina category?
This category includes prescription medicines used to prevent episodes and to relieve acute chest discomfort. You can browse short-acting sublingual tablets for fast relief, long-acting nitrates for prevention, and common preventive classes like beta-blockers and calcium channel blockers. Listings may change as suppliers update stock, strengths, and pack sizes. Always review product labeling and discuss choices with a clinician if you have new or changing symptoms.
Do I need a prescription for these medications?
Most therapies for chest pain prevention or relief require a valid prescription. Availability depends on the specific agent and jurisdictional rules. Some over-the-counter products may ease unrelated indigestion but do not treat ischemic chest discomfort. If you have new, severe, or worsening pain, seek urgent medical care rather than browsing. Your clinician can confirm diagnosis and recommend appropriate therapy and monitoring.
How are sublingual nitroglycerin tablets stored and shipped?
Sublingual tablets should remain in their original, tightly closed container to protect from air and moisture. Keep them at room temperature, away from heat and light. During shipping, items are packed to maintain labeled conditions. After opening, check expiration dates and replace tablets on schedule. Follow the product insert for repeat dosing limits and spacing. Never combine with certain erectile dysfunction drugs due to serious interaction risks.
Can I filter by strengths and dosage forms?
Yes. You can compare dosage forms such as sublingual tablets, immediate-release tablets, and extended-release tablets, along with common strengths for each product. Review dosing intervals, maximum daily doses, and nitrate-free intervals where applicable. Consider your current regimen, blood pressure, and heart rate before selecting. If unsure, review the patient information leaflet and consult a clinician to align choices with your treatment plan.
Are brand and generic options available for preventive therapy?
Both brand-name and generic products may appear, depending on current supplier inventory. Generics contain the same active ingredient and meet bioequivalence standards. You can compare price, strength, and release profile to find a suitable option. Some patients prefer extended-release generics for once-daily dosing, while others use a combination strategy. Stock may vary, so check listings periodically for updates.
