Angiotension II receptor agonists
Also known as ARBs, they work in a very similar way to ACE inhibitors, but are don't cause a dry cough. In time, they may replace ACE inhibitors as the first line treatment. More on them here.
There are a variety of antiarrhythmic drugs (possibly the hardest word to spell in the whole world).
Beta blockers make the heart pump slower and less hard. Common ones are propanolol, bisoprolol and atenolol. They are mainly used to prevention of MIs and deal with tachyarrhythmias. See the beta blockers page for more.
Calcium channel blockers
Calcium channel blockers have a wider range of effects. Some, like verapamil, make the heart pump slower and less hard. Others, like nifidipine mostly just dilate blood vessels in the heart and body, meaning they are used to treat angina. Find out more on the calcium channel blockers page.
These are used to treat angina. There are two main types, glyceryl trinitrate - well known in the GTN spray - and isosorbide dinitrate, used sublingually and for prophylaxis. More on the nitrates page.
