Others drugs of antianginal classification Flashcards
Adverse β-Blocker Adverse Effects
bronchospasm;
bradycardia, CH, AV blockade, hypotension;
↓ peripheral, cerebral blood flow - weakness, fatigue;
metabolic disorders: increased atherogenesis, hypoglycemia
dyspeptic symptoms;
Applied for the treatment of coronary artery disease on the background of hypertension and tachyarrhythmias, appropriate combination with nitrates.
Antihypoxants
myocardial tolerance hypoxia;
in conditions of chronic hypoxia, cause the activation of anaerobic processes and inhibits aerobic;
inhibit tissue respiration;
show efficiency at a widespread sclerosis of coronary vessels, intended for military purposes
Ivabradine (coraxan) - selective If – inhibitor
specific blocker of incoming ion current through mixed Na / K channels, which
- determines the pacemaker activity,
- activated at the time of hyperpolarization, participate in the occurrence of a phase of spontaneous slow diastolic depolarization in the sinus node cells
determines the heart rate.
Drugs increasing the delivery of O2 to the myocardium
Vasodilator drugs of myotropic action: Dipyridamole (Curantil), carbocromen. increases the volumetric rate of coronary blood flow and O2 delivery, increase the number of collaterals; have antiplatelet effect; reduce blood pressure, increase heart rate; normalizes lipid metabolism cause dyspeptic symptoms; headache; hypotension.
Drotaverine (no-shpa) and papaverine
Reduce the tone of the smooth muscles of blood vessels, including coronary, increasing the delivery of O2 to the myocardium and internal organs (colic);
Papaverine impairs myocardial conductivity.
Moderately reduce blood pressure;
are of secondary importance and are used to prevent attacks of stenocardia, chimes - for bicycle ergometric tests (for determining the functional reserve).
Reflex vasodilators (validol)
It acts from the cold receptors of the oral cavity, reflexively expanding the coronary vessels;
The onset of action is 1 min, the duration of action is 10-15 min .;
take under the tongue in the form of a solution on a piece of sugar, capsules and tablets.
Ineffective! Used for the relief of attacks, in the early stages of coronary artery disease.
Reduces headache caused by the use of nitroglycerin.
Stable analogues of prostacyclin
Ailoprost, carbacyclin
prostacyclin - a short-lived prostanoid (1.5 min), an endogenous regulator of vascular tone
dilate blood vessels
↓ platelet aggregation,
stabilize lysosome membranes (↓ necrosis).
Rarely used, place in the treatment of CHD is not defined
