Contact Our PharmacyWhat Is Atenolol?
Atenolol is a beta-blocker frequently prescribed in veterinary medicine to help control systemic hypertension, heart rhythm disorders (arrhythmias), and certain forms of heart disease in dogs and cats. Because commercial tablets are typically too large or not flexible enough for precise veterinary dosing, compounded atenolol provides veterinarians with pet-appropriate strengths, formats, and flavors.
How Atenolol Works in Pets
Atenolol works by blocking beta-adrenergic receptors in the heart, which slows the heart rate, lowers blood pressure, and decreases the heart’s oxygen demand. This makes it especially useful for cats with hypertrophic cardiomyopathy and dogs with systemic hypertension or tachyarrhythmias. By reducing cardiac workload, atenolol helps improve both comfort and long-term outcomes in pets with cardiovascular disease.
Veterinary Dosage Forms
Our compounded atenolol formulations are designed for accurate dosing and easier administration across a wide range of pet sizes and temperaments.
Capsules
Custom strengths typically compounded for small pets and large dogs; allows precise oral dosing.
Oral Suspension
Flavored liquids (commonly compounded between 1 mg/mL – 10 mg/mL) to simplify administration for cats and small dogs.
Oral Paste
Semi-solid paste, often standardized around 12.5 mg/mL; convenient dial-a-dose option for pets resistant to liquids or capsules.
Transdermal Gel
Applied via micro-dosing (0.1 mL) applicator; customizable strengths, often chosen for cats and small dogs that resist oral dosing.
Chewable Treats
Flavored chewables (chicken, beef, liver, fish, and more), ideal for picky pets; compounded in veterinarian-directed strengths.
