Norvasc vs Bystolic
Introduction
For patients dealing with hypertension or high blood pressure, certain classes of drugs that act on the cardiovascular system can help in managing symptoms and reducing risks associated with elevated blood pressure levels. Norvasc and Bystolic are two such medications commonly prescribed for this purpose. They each work differently to control blood pressure but both have effects aimed at relaxing the heart's workload. Norvasc is a calcium channel blocker (CCB) which works by preventing calcium from entering specific muscle cells in the heart and arteries, thereby allowing them to relax more easily. On the other hand, Bystolic falls under the category of beta blockers; it primarily affects cardiac activity by blocking epinephrine's action on beta receptors thus slowing down your heartbeat.

What is Norvasc?
Amlodipine (the generic name for Norvasc) is a calcium channel blocker used to treat high blood pressure and angina. It was first approved by the FDA in 1992. Amlodipine works by relaxing your blood vessels, allowing blood to flow more easily, thus lowering your blood pressure. It's typically prescribed for hypertension and coronary artery disease.
On the other hand, Nebivolol (the generic name for Bystolic), which falls under the category of beta blockers, slows down your heart rate and reduces its workload. First approved by the FDA in 2007, it's primarily used to manage hypertension.
Both drugs are efficient at controlling high blood pressure; however, they work differently in our bodies due to their unique mechanisms of action. While both have been reported as relatively well-tolerated with minimal side effects compared with similar medications in their respective classes, individual responses can vary widely based on several factors including age, overall health status and presence of other diseases.
What conditions is Norvasc approved to treat?
Norvasc is approved for the treatment of various cardiovascular conditions:
- Hypertension, also known as high blood pressure
- Coronary artery disease (CAD), specifically for symptomatic relief of stable angina and vasospastic angina
- It can also be used to reduce the risk of hospitalization due to angina and decrease the risk of a coronary revascularization procedure.
How does Norvasc help with these illnesses?
Norvasc is a medication that manages hypertension and chest pain by relaxing the blood vessels, allowing them to widen. It does this by blocking calcium from entering certain tissues and arteries. This action prevents muscle contraction in the artery walls, thereby expanding blood vessels which helps improve blood flow. Bystolic, on the other hand, works differently as it belongs to a class of drugs known as beta blockers. Beta blockers work by affecting the response to certain nerve impulses in your body, hence slowing down your heart rate and reducing its workload. Bystolic also lowers blood pressure thereby lessening the risks associated with high pressure such as strokes and heart attacks. Both medications are effective for managing cardiovascular diseases but their mode of operation differs significantly.
What is Bystolic?
Bystolic, known generically as nebivolol, is a beta-blocker that primarily treats hypertension or high blood pressure. It functions by blocking the effects of the hormone epinephrine (also called adrenaline) on the heart and blood vessels. This action leads to a decrease in heart rate, blood pressure, and strain on the heart. The FDA approved Nebivolol in 2007.
Unlike Calcium channel blockers such as Norvasc (Amlodipine), Bystolic does not directly act on calcium channels to dilate blood vessels but achieves similar results through its effect on beta receptors. Its side-effect profile also tends to be different from that of calcium channel blockers; it may cause less fluid build-up or edema - a common side effect associated with drugs like Norvasc.
Moreover, nebivolol has unique vasodilatory properties which might offer additional benefits for hypertensive patients who require reduction in their vascular resistance without consequential increase in cardiac output.
What conditions is Bystolic approved to treat?
Bystolic is a medication that has been approved for the treatment of particular cardiovascular conditions like:
- Hypertension, also known as high blood pressure
- Heart failure in certain patients to reduce the risk of cardiovascular death and hospitalization related to heart failure. It's essential to note that Bystolic must be started at a low dose and carefully adjusted.
How does Bystolic help with these illnesses?
Nebivolol, also known by the brand name Bystolic, works as a beta blocker to decrease heart rate and reduce blood pressure. Its primary action is on the beta-1 adrenergic receptors in the heart and vascular smooth muscle, thereby reducing cardiac output and systemic vascular resistance. In contrast to other similar medications like Norvasc (a calcium channel blocker), Bystolic has vasodilatory properties that can further lower blood pressure. It's often prescribed when patients do not respond well or have side effects with traditional antihypertensive drugs such as calcium channel blockers. Moreover, it may be combined with these types of medication for more effective treatment of hypertension or specific cardiovascular conditions.
How effective are both Norvasc and Bystolic?
Both amlodipine (Norvasc) and nebivolol (Bystolic) have proven effectiveness in managing hypertension, with their approval by the FDA separated by more than a decade. They act on different pathways to achieve blood pressure control, which can influence the circumstances under which they might be prescribed. The efficacy of amlodipine and nebivolol in managing high blood pressure was directly compared in several clinical trials; both drugs showed similar proficiency in lowering systolic and diastolic blood pressures, along with comparable safety profiles.
A review done in 2007 reported that Norvasc is an effective treatment for hypertension from the first dose onwards, its side effect profile compares favorably against many other antihypertensives, and it is well-tolerated across various patient groups including elderly individuals. Notably, due to its long half-life leading to sustained effects over 24 hours, once daily dosing is usually sufficient. As one of the most-prescribed antihypertensive medication worldwide, there's substantial evidence supporting its use for treating high blood pressure.
As per a meta-analysis conducted in 2014 indicated Bystolic’s effectiveness seems superior to placebo while being equally efficacious as other commonly used beta-blockers for controlling hypertension. However,Bystolic may not always be considered as first-line therapy; preferred initial treatments usually include thiazide diuretics or ACE inhibitors depending upon individual patient characteristics.In addition,due to unique properties like vasodilation alongwith beta-blocking activity,Bystolic could be beneficial for patients who require heart rate control without associated vasoconstriction or those prone to adverse metabolic effects seen with older generation beta blockers.

At what dose is Norvasc typically prescribed?
Oral dosages of Norvasc range from 2.5–10 mg/day, but studies have shown that 5 mg/day is sufficient for treating high blood pressure in most adults. Children and adolescents may be started on 2.5 mg/day depending upon the severity of hypertension or angina. If necessary, dosage can be increased after a few weeks if their blood pressure goal is not achieved. The maximum dosage that should not be exceeded in any case is 10 mg/day.
On the other hand, oral dosages of Bystolic range from 2.5-40mg a day with the usual starting dose being at least 5mg once daily for most patients suffering from high blood pressure or heart failure; however this might differ for those with kidney problems where lower doses might suffice initially.
It's crucial to note that both medications must only be adjusted under your doctor's supervision as they take into account various factors such as age, medical condition and response to treatment among others.
At what dose is Bystolic typically prescribed?
Bystolic treatment is generally initiated at a dose of 5 mg/day, to be taken orally once daily. Depending on the patient's response to this initial dosage, it can then be increased up to 10 mg/day after two weeks if necessary. For some patients with severe kidney or liver disease or older than 75 years old, the starting dose should not exceed 2.5 mg/day. The maximum advised dosage of Bystolic is set at 40 mg per day but this high dosage may only be considered after professional medical consultation and if there hasn't been any significant improvement in the patient's condition with lower dosages within a few weeks.

Contraindications for Norvasc and Bystolic?
Just like with any other cardiovascular medications, both Norvasc and Bystolic may cause certain side effects. If you notice a worsening of your symptoms or any new health concerns while taking these drugs, it is crucial to seek immediate medical attention.
You should never use either Bystolic or Norvasc if you are already taking some specific types of heart medication such as Sildenafil (Viagra) for chest pain or nitroglycerin. Always communicate clearly with your healthcare provider about all the medicines you are currently on; this will help in avoiding potential hazardous interactions between Norvasc and Bystolic with other medications.
Moreover, individuals who have liver disease, kidney disease, congestive heart failure or similar conditions should exercise caution when considering these medications. Your doctor might need to adjust your dosage accordingly based on the severity of your condition.
How much do Norvasc and Bystolic cost?
For the brand name versions of these drugs:
- The price of 30 tablets of Bystolic (5 mg) averages around $150, which works out to approximately $5/day.
- The price for 30 tablets of Norvasc (10 mg), on the other hand, is about $100 and translates to roughly $3.33 per day.
If you are prescribed a higher dose range for Bystolic (i.e., 20 mg/day or higher), then brand-name Norvasc is less expensive on a per-day treatment basis. It's important to note that cost should not be your primary consideration in determining which medication is right for you.
As far as generic versions go, prices drop significantly:
- Nebivolol (generic Bystolic) costs between $0.45 and $1.50 per day depending on whether your daily dosage falls within the typical range of 5mg up to 40mg.
- Amlodipine Besylate (generic Norvasc) comes in packs starting from fifteen up to hundreds with an average cost ranging between mere cents ($0.07/day if bought in larger quantities upfront) and about seventy-five cents ($0.75/day).
Popularity of Norvasc and Bystolic
Amlodipine, also known by its brand name Norvasc, was estimated to have been prescribed to about 75 million people in the US in 2020. Amlodipine accounted for a significant part of prescriptions for antihypertensives in the US. It is classified as a calcium channel blocker and primarily used to treat high blood pressure and angina (chest pain). The use of Amlodipine has remained relatively consistent over recent years.
Nebivolol or Bystolic, on the other hand, was prescribed to approximately 8 million individuals in the USA within the same year. In terms of overall beta-blocker prescriptions in America, Nebivolol accounts for just under 10%. This medication is also used primarily for managing hypertension. Over time we've seen an increasing trend towards prescribing Nebivolil - this may be due to its unique pharmacological properties that allow it to offer additional benefits such as improving endothelial function and potentially offering some degree of cardio-protection.
Conclusion
Both Norvasc (amlodipine) and Bystolic (nebivolol) have well-established records of usage in patients with hypertension, backed by numerous clinical studies indicating their effectiveness compared to placebo treatments. They may be used together in some cases; however, this decision should be made under the careful consideration of a physician due to potential drug interactions. Their mechanisms of action are different: Norvasc is a calcium channel blocker that widens blood vessels and improves blood flow, while Bystolic is a beta-blocker that slows heart rate and reduces the force with which the heart muscle contracts.
Norvasc can be considered as a first-line treatment option for high blood pressure whereas Bystolic might also be prescribed as an adjuvant therapy or for those who didn't respond well to first-line antihypertensive medications or need additional control over their heart rate.
Both drugs are available in generic form, leading to significant cost savings especially for patients paying out-of-pocket. Both Norvasc and Bystolic require time for full therapeutic effect meaning results may not appear immediately.
The side effect profile differs between these two drugs; both are generally well-tolerated but they come with unique risks. For example, Norvasc could lead to peripheral edema (swelling), while Bystolic could cause fatigue or slow heartbeat. It's crucial that anyone taking these medications monitor their health closely and seek immediate medical attention if serious problems arise.
