Specific patent expiry dates can vary by region and the type of patent, but the drug has been available generically for many years.

What is atenolol used for?
Atenolol is a beta-blocker medication prescribed to treat a variety of cardiovascular conditions. It is commonly used to manage high blood pressure (hypertension) and to prevent chest pain (angina pectoris) in patients with heart disease. It can also be used after a heart attack to improve the chances of survival [2].
How does atenolol work?
As a beta-blocker, atenolol works by blocking the effects of adrenaline (epinephrine) on the heart and blood vessels. It slows down the heart rate, reduces the force with which the heart pumps blood, and widens blood vessels. This combined effect helps to lower blood pressure and reduce the heart's workload [2].
What are the common side effects of atenolol?
Common side effects associated with atenolol include fatigue, dizziness, slow heart rate, cold hands and feet, and shortness of breath. Less common side effects may include nausea, diarrhea, and changes in mood [2].
Can atenolol be taken with other medications?
Atenolol can interact with various other medications. It is important to inform a healthcare provider about all other drugs, supplements, or herbal products being taken. Interactions can occur with other blood pressure medications, certain heart rhythm drugs, and medications that affect the central nervous system [2].
What are the risks if I stop taking atenolol abruptly?
Stopping atenolol suddenly can be dangerous. It may lead to a sudden increase in blood pressure, chest pain, or even a heart attack. If a change in medication is needed, a healthcare provider will typically recommend gradually reducing the dosage over time [2].
Are there alternatives to atenolol for high blood pressure?
Yes, there are many alternative medications for high blood pressure, including other classes of drugs such as ACE inhibitors, calcium channel blockers, diuretics, and ARBs. The choice of medication depends on individual patient factors, including other medical conditions and potential side effects [3].
