Study Notes
Therapeutic Drug Classes
-
Antithrombotic Therapies prevent blood clots.
-
Antiplatelet drugs inhibit platelet aggregation.
- Aspirin is a common antiplatelet.
- P2Y₁₂ antagonists (clopidogrel, prasugrel, ticagrelor) are also antiplatelet.
-
Anticoagulants prevent blood clot formation.
- Warfarin (VKA) is an older anticoagulant.
- DOACs (Apixaban, Dabigatran) are newer, quicker-acting anticoagulants.
- Heparins are another type of anticoagulant.
-
Thrombolytics dissolve existing blood clots.
- Alteplase and Tenecteplase are thrombolytics.
-
Antiplatelet drugs inhibit platelet aggregation.
-
Antianginal drugs treat angina (chest pain).
-
Antiarrhythmic drugs treat abnormal heart rhythms.
-
Cardioinhibitory drugs slow the heart rate.
-
Cardiostimulatory drugs increase the heart rate.
-
Diuretics increase urine production.
-
Pressor drugs increase blood pressure.
-
Vasoconstrictor drugs narrow blood vessels.
-
Vasodilator drugs widen blood vessels.
-
Antihyperlipidemics lower lipid levels in blood.
-
Beta blockers are sympatholytic drugs blocking adrenaline and noradrenaline effects.
- They indirectly influence the renin-angiotensin system (RAS) at the kidneys.
- They slow the heart rate (negative chronotropy) by blocking the sympathetic nerve stimulation at the SA and AV nodes.
- They reduce myocardial oxygen demand by decreasing contractility and afterload (antianginal effect).
- Used for various conditions including anxiety and migraine, alongside heart related conditions (antianginals, antihypertensives, antiarrhythmic, cardioinhibitory, heart failure).
Hypertension
- Hypertension is a condition characterized by chronically elevated arterial blood pressure.
- It is a leading cause of disease burden globally, and in the UK.
