Dose and Administration: 70mg daily in two divided doses.
Indications: treatment of angina in patients in normal sinus rhythm.
Contraindications: severe bradycardia (not to be initiated if heart rate below 60 beats per minute); cardiogenic shock; acute myocardial infarction; immediately after cerebrovascular accident; sick-sinus syndrome; sino-atrial block; moderate to severe heart failure; patients with pacemaker; unstable angina; second- and third-degree heart block; congenital QT syndrome; pregnancy and breast-feeding.
Dose and Administration: Initially 5 mg twice daily, increased if necessary after 3–4 weeks to 7.5 mg twice daily (if not tolerated reduce dose to 2.5–5 mg twice daily); elderly initially 2.5 mg twice daily
Peripheral Vasodilators and Related Drugs:
Indications: treatment of patients with intermittent claudication on the basis of chronic occlusive arterial disease of the limbs. It may improve function and symptoms but is not intended to replace more definitive therapy, such as surgical bypass, or removal of arterial obstructions when treating peripheral vascular disease.
Contraindications: cerebral haemorrhage, extensive retinal haemorrhage, acute myocardial infarction; pregnancy and breast-feeding
Dose and Administration: 400 mg 2–3 times daily
Indications: Treating hemorrhoids, Treating leg ulcers caused by poor circulation, when used in combination with hesperidin.
Contraindications: pregnancy and breast-feeding.
Dose and Administration: For the treatment of internal hemorrhoids: 1350 mg of diosmin plus 150 mg of hesperidin twice daily for 4 days followed by 900 mg of diosmin and 100 mg of hesperidin twice daily for 3 days. Some researchers also try 600 mg of diosmin three times daily for 4 days, followed by 300 mg twice daily for 10 days, in combination with 11 grams of psyllium daily. However, this lower diosmin dose does not seem to be as effective. For prevention of relapse internal hemorrhoids: 450 mg of diosmin plus 50 mg of hesperidin twice daily for 3 months of therapy. For the treatment of leg wounds due to bloodflow problems (venous stasis ulcers): the combination of 900 mg of diosmin and 100 mg of hesperidin daily has been used for up to 2 months
Beta Hydroxyethyl Rutosides:
Indications: indicated for oedema and symptoms (painful, tired, heavy, swollen legs with cramps and paraesthesia) associated with chronic venous insufficiency; postphlebitic syndrome, trophic disorders, varicose dermatitis and varicose ulcers.
