Cardiac drugs

This dog is suffering from a persistent dry cough due his antihypertensive medication - rampril. It's probably time he was switched to an ARB instead.

The heart is very useful, and cardiologists attempt to keep it that way. The drugs they use are below:

ACE inhibitors

ACE inhibitors inhibit the action of the ACE enzyme, reducing blood pressure. Common ones are ramipril and perindopril. They are used the treat hypertension. See the ACE inhibitor page for more.

Angiotension II receptor agonists

Also known as ARBs (angiotensin II receptor blockers), they work in a very similar way to ACE inhibitors, but are don't cause the dry cough. In time, they may replace ACE inhibitors as the first line treatment.

Common types and doses

• Losartan 50mg OD, upto 100mg in hypertension.
• Candestartan 32mg OD.

Antiarrhythmics

There are a variety of antiarrhythmic drugs (possibly the hardest word to spell in the whole world).

The most well known are beta blockers and calcium channel blockers, however there are many more types. Visit the page on antiarrythmics to find out more about them.

Beta blockers

Beta blockers make the heart pump slower and less hard. Common ones are propanolol and atenolol. They are mainly used to prevention of MIs and deal with tachyarrhythmias. See the beta blockers page for more.

Diuretics

Diuretics are used to control hypertension, by reducing the amount of fluid in the body. They are so sexy that they have their own page. Check it out!
