An FBC not only tests for disorders and abnormalities of the blood but, as blood travels throughout the whole body, it can give an indication of disease present in other organs. An FBC, as the name suggests, is used to obtain a count of the blood cells in the sample of blood taken.
Flecainide is a sodium channel blocker used mainly in the treatment of supraventricular arrhythmias. Central nervous system side effects such as dizziness, visual disturbances, headache and nausea are commonly associated with flecainide, but severe central nervous system toxicity is rare.
Amlodipine is a long-acting calcium channel blocker used as an anti-hypertensive, and in the treatment of angina. As with other calcium channel blockers, amlodipine acts by relaxing the smooth muscles in the arterial wall, decreasing peripheral resistance and hence improving blood pressure. In angina it improves blood flow to the myocardium. It was developed under the direction of Dr. Simon Campbell.
