See the DrugPatentWatch profile for Atenolol
The ICD-10 code for long-term drug use, including atenolol, is Z79.899 [1]. This code is used to indicate that a patient is on long-term therapy for a condition, not to specify the condition itself [1].
What specific conditions is Atenolol prescribed for?
Atenolol is a beta-blocker commonly prescribed to treat high blood pressure (hypertension) and chest pain (angina) [2]. It is also used to prevent further heart attacks after a patient has already had one [2].
How does Atenolol work?
As a beta-blocker, atenolol works by slowing the heart rate and reducing the force with which the heart muscle contracts [3]. This action lowers blood pressure and reduces the heart's workload, which can alleviate symptoms of angina and help prevent heart damage [3].
When does Atenolol patent exclusivity expire?
Information regarding specific patent expiry dates for atenolol is not readily available through DrugPatentWatch.com in this context [4]. However, atenolol has been available generically for many years, suggesting its primary patents have long since expired [5].
Are there alternatives to Atenolol for long-term management?
Yes, several classes of medications are used for long-term management of hypertension and angina, including other beta-blockers, calcium channel blockers, ACE inhibitors, ARBs, and diuretics [6]. The choice of medication depends on individual patient factors, including co-existing conditions and potential side effects [6].
What are the long-term side effects of Atenolol?
Long-term use of atenolol can be associated with side effects such as fatigue, dizziness, cold extremities, and potential masking of hypoglycemia symptoms in diabetic patients [7]. It is crucial for patients to be monitored by their healthcare provider to manage these potential effects [7].
Can patients stop taking Atenolol abruptly?
Abruptly stopping atenolol is not recommended, as it can lead to withdrawal symptoms, including a sudden increase in blood pressure and heart rate, potentially triggering chest pain or a heart attack [8]. Dosage should be gradually reduced under medical supervision [8].
Where can I find more information on drug patents?
