Diltiazem

• Diltiazem is available by prescription only.

• Diltiazem is an extra-label calcium channel blocker prescribed to dogs and cats suffering from different heart conditions that include...

• hypertrophic cardiomyopathy, or thickened heart walls

• high blood pressure

• irregular heartbeats

• Calcium enters the heart through calcium channels and causes the heart muscle and blood vessels to contract, making it harder to pump blood through the body.

• Diltiazem blocks these calcium channels, reducing the contraction of the heart muscle and dilating the arteries.

• This slows the heart beat and lowers blood pressure, allowing the heart to pump blood more efficiently.

• Extended Release (ER) capsules come in two different capsule types. Ask your veterinarian which type of extended release capsule will work best for you and your pet.

• Dilacor XR Capsules can be opened and contain a tablet, which may make giving diltiazem to your pet easier, especially if your pet has trouble taking pills.

• Cardizem CD Capsules should not be opened, but can work well for pets who take pills easily.

• Keep out of the reach of children and pets.

• Diltiazem should not be used in animals with known allergies to this drug.
