      2.6.2 Calcium Channel Blockers
                    Amlodipine is for angina and hypertension, has a longer duration of action and can be given once a day. 
                    It should be prescribed generically as amlodipine.  The besilate salt should not be prescribed as this is more expensive.
                    GREEN       Amlodipine (as maleate/mesilate salt only) tablets 5mg, 10mg
 
                    Lercanidipine or Lacidipine can be used as a  second line calcium channel blocker when amlodipine is not tolerated
                    (e.g. where patients develop significant ankle oedema).

        2.6.3 Other antianginal drugs
                   Nicorandil
                   Nicorandil, a potassium channel activator with a nitrate component, has both arterial and venous dilating properties
                   and is licensed for the prevention and  long-term treatment of chronic stable angina pectoris. It is usually prescribed in
                   addition to isosorbide mononitrate if symptoms remain uncontrolled.  Patients already receiving MAXIMAL therapy
                   with two antianginal medications (e.g. calcium channel blocker and nitrates) should be referred to a specialist for
                   further assessment.
                   GREEN      Nicorandil tablets 10mg, 20mg
 
                   Ivabradine
                   Chronic Stable Angina
                     °   Ivabradine should only be initiated by specialists in the treatment of chronic stable angina.
                     °   Ivabradine has not demonstrated any increased benefits in terms of efficacy and safety over other available 
                          treatments for angina, and is considerably more expensive.
                     °   It is recommended for symptomatic treatment of chronic stable angina pectoris in patients with normal sinus
                          rhythm for whom heart rate control is desirable and for whom beta-blockers and calcium-channel blockers are
                          inappropriate or not tolerated. Long-term protection against cardiovascular events, however, has not been 
                          demonstrated.
                     °   Therefore patients already receiving MAXIMAL therapy with two antianginal medications (e.g. calcium channel  
                          blocker and nitrates) should be referred to a specialist for further assessment.
                     °   There is no evidence that addition of a third drug improves symptom control.  If a third drug (e.g. nicorandil) is 
                         introduced while awaiting an outpatient appointment, its effects should be monitored and if it has no effect it should 
                         be stopped.

                   Chronic Heart Failure

                  Ranolazine
                  Ranolazine should only be initiated by specialists in the treatment of chronic stable angina.
                  It is recommended as add on therapy for symptomatic treatment of patients with stable angina whose symptoms are
                  inadequately controlled or intolerant  of first-line anti-anginal therapies, nitrates and/or nicorandil, and third line 
                  ivabradine.

        2.6.4 Peripheral vasodilators and related drugs
                  Nifedipine may be useful for reducing the frequency and severity of vasospastic attacks in Raynaud’s syndrome.
                  [Nifedipine immediate release capsules have been discontinued and the use of MR 10mg, 20mg  BD has been approved for use]
                  Nifedipine is no longer recommended for the treatment of hypertension and angina.

                  NICE guidance for peripheral arterial disease (TAG 223)
                  Naftidrofuryl oxalate is recommended as an option for the treatment of intermittent claudication in people with
                  peripheral arterial disease for whom vasodilator therapy is considered appropriate after taking into account 
                  other treatment. Treatment with naftidrofuryl oxalate should be started with the least costly licensed preparation i.e.  
                  generic prescribing only.
