Dr. Ivana Daň ková Dept. of Natural Drugs, Faculty of Pharmacy, VFU Brno PHYTOPHARMACEUTICALS in the treatment of some CIRCULATORY DISORDERS Circulatory disorders ► is any disorder or condition that affects circulatory system ► Circulatory disorders can arise from problems with the heart, blood vessels or the blood itself. Disorders of the circulatory system generally result in diminished flow of blood and oxygen supply to the tissues. ► They can be classified into 5 groups: traumatic, compressive, occlusive, tumors/malformations and vasospastic (spasm of the artery, which reduces its diameter and thus its blood flow) ► 2 PHYTOPHARMACEUTICALS in the treatment of some CIRCULATORY DISORDERS ► Peripheral vascular diseases (PVDs) are circulation disorders that affect blood vessels outside of the heart and brain. PVD typically strikes the veins and arteries that supply Jower body", the arms, legs = peripheral vessels. ► In PVD, blood vessels are narrowed. Narrowing is usually caused by arteriosclerosis = a condition where plaque builds up inside a vessel. It is also called "hardening of the arteries." Plaque decreases the amount of blood and oxygen supplied to the arms and legs. ► As plaque growth progresses, clots may develop. This further restricts the affected vessel. Eventually, arteries can become obstructed. ► 3 PHYTOPHARMACEUTICALS in the treatment of some CIRCULATORY DISORDERS ► PVD that develops only in the arteries is called peripheral arterial disease (PAD) This is the most common form of PVD. ► PVD may also be referred to as: ► arteriosclerosis obliterans ► arterial insufficiency of the lower limbs (legs) claudication ► intermittent claudication PHYTOPHARMACEUTICALS in the treatment of some CIRCULATORY DISORDERS Raynaud's phenomenon is believed to be the result of vasospasms that decrease blood supply to the respective regions in response to cold or emotional stress (vasoneurosis), causing discoloration of the fingers, toes, and occasionally other areas. Constricted digital arteries block Mood to finger tips, causing discoloration Digital arteries supply blood to fingers ► 5 PHYTOPHARMACEUTICALS in the treatment of some CIRCULATORY DISORDERS ► Preparations containing Ginkgo bilobae extract ► Ginkgo dry extract (22.0-27.0 % flavonoids, 2.6-3.2 % bilobalide, 2.8-3.4 % ginkgolides) = EGb 761 ► It has especially following effects: ► vasodilating of small arteries (it widens them) ► rheological (it improves rheological properties of blood) ► it decreases agglomeration of blood platelets and red blood cells ► promotes venous tone (tension) ► decreases increased permeability of capillaries and so acts against oedemas ► improves intracellular utilization of glucose and also acts against the presence of so-called free radicals. ► 6 PHYTOPHARMACEUTICALS in the treatment of some CIRCULATORY DISORDERS ► EGb761 ► Indications: vascular disorders ► peripheral arterial occlusive disease of legs (claudication), vasospasms, Raynaud's phenomen ► sensory disorders of vascular and involution origin (tinnitus, vertigo, hearing and sight disorders) ► treatment of cerebral vascular insufficiency - dementia, mental losses due to organic brain syndrome ► TANAKAN (Ipsen Ltd.) tanakan SUKLcode : 0062914; ATC: N06DX02 ► TEBOKAN (Dr. Willmar Schwabe GmbH & Co) ► SUKLcode: 0075124; ATC: N06DX02 further information about preparations in lecture 4 Ginkgo bilobae folium ► food suplements ► solid forms - tablets, capsules, content usually 40, 80 mg to 120 mg ► producers: Walmark, Dr. Müller Pharma, MedPharma, NefDesante, Swiss, GS, Favea... ► composite preaprations, e.g.: ► GINKOPRIM (Walmark) - contains 40 mg Egb 761 and 150 mg Mg2+ ► liquid preparations - herbal drops, tinctures herbal teas GINKGO I ««i BILOBA J GINKGO GinkoPrim \ ► 8 PHYTOPHARMACEUTICALS in the treatment of VENOUS DISEASES VENOUS DISEASES to heart refers to all conditions related to or caused by veins that become diseased or abnormal ► about 15 percent of adult population is affected ► In the normal circulation, arteries carry oxygen rich blood from your heart to the body, and veins return the blood toyour heart. Veins have one-way valves along their length to keep the blood flowing to the heart. As muscles contract, the blood is squeezed forward in the veins. When muscles relax, the valves shut to prevent blood from flowing backward. relaxed skeletal muscle blood squeezed forward to heart contracted skeletal muscle valve open valve closed ► 9 PHYTOPHARMACEUTICALS in the treatment of VENOUS DISEASES If the vein walls become weak or damaged, or if the valves are stretched or injured, the system stops working normally and the blood begins to flow backward when the muscles relax. This creates unusually high pressure in the veins, resulting in even more stretching, twisting, and swelling of veins. ► 10 PHYTOPHARMACEUTICALS in the treatment of VENOUS DISEASES Venous diseases of lower limbs (legs) include: ► spider veins, varicose veins ► leg swelling, leg pain ► chronic venous insufficiency (CVI) leg skin changes, leg ulcers ► phlebitis = inflammation of the vein, usually accompanied with thrombosis - thrombophlebitis ► phlebotrombosis - deep vein trombosis Normal vein Varicose veins Thrombophlebitis Blood flow Closed valve Varicose vein Open valve ► ii PHYTOPHARMACEUTICALS in the treatment of VENOUS DISEASES ► Venous diseases are caused by a damage of the vein wall -lower elasticity and tensile strength of the vein wall —> increased permeability and fragility of the capillaries ► —> local bleeding, swelling, inflammation, thrombosis ► The poorly functioning valves allow blood to flow backward, which causes pooling (congestion) in the veins, worse venous return —> increasing pressure inside the veins —> veins become „leaky" Normal Vein Damage ^ Venous Valve ^ Venous Function to Venous Valves r Insufficiency ^Hypertension ► 12 PHYTOPHARMACEUTICALS in the treatment of VENOUS DISEASES Therapy of venous diseases: ► supporting of venous return physical training ► massage ► compression stockings ► sclerotherapy, endovenous laser ablation, phlebectomy...
