International Nonproprietary Name: Atenolol

Atenolol, a widely recognized medication, is the active ingredient found in Tenormin, a brand prominently used in Canada and other regions. This medication belongs to a class known as selective beta-blockers.

Brand Names in Canada

In Canada, Tenormin is the most recognized brand name for Atenolol. This product may be available in various formulations and strengths. As with many medications, there are generic equivalents, such as Atenolol itself, which may be available under different brand names depending on the manufacturer. These variations include various packaging options to accommodate patient needs.

ATC Code & Classification

The Anatomical Therapeutic Chemical (ATC) code for Atenolol is C07AB03. This categorizes it within the cardiovascular system, specifically as a selective beta-blocker. Beta-blockers function primarily by blocking the effects of adrenaline, leading to a decrease in heart rate and blood pressure, making them invaluable in managing cardiovascular conditions.

Dosage Forms Available

Atenolol is typically available in oral tablet form, with strengths of 25 mg, 50 mg, and 100 mg. These tablets are conveniently packaged in blisters or bottles, providing flexibility for dosing routines.

Manufacturers

Atenolol is produced by AstraZeneca as the original inventor and brand owner of Tenormin. Several other generic manufacturers also produce Atenolol, including Zentiva, Sandoz, and Teva. This diversity enables broader access to the medication across various pharmacy settings in Canada.

Registration Status

In Canada, Atenolol is classified as a prescription-only medication. It requires a healthcare provider's approval to ensure it is used safely and effectively. Regulatory bodies such as Health Canada oversee its approval and usage, ensuring adherence to safety standards. This classification is not unique to Canada; it mirrors the prescription-only status mentioned in many other major markets across the globe.

• Arrhythmias: Doses typically range from 50 mg to 100 mg.

Adjustments may be necessary based on factors like age and other health conditions.

• Children: Usage is rare and typically requires specialist input.
