2nd Class Flashcards
1
Q
Metoprolol Tartrate (tab 50mg;100mg)
A
A= adrenonegative drug, cardiology selective beta1 antagonist without ISA + Class 2 antiarrhytmic drug B= blocks beta1>beta2 (cardioselective) --> reduces cardiac output (negative ino/batmo/chrono/dromotropic effects). Also have antihypertensive properties by blocking the effects of renin (decreases plasma renin levels thereby decreasing the effect of RAAS on bp) C= angina pectoris, hypertension, arrhythmias, migraine, stenocardia, acute myocardial infarction, chronic heart failure!
2
Q
Bisoprolol (tab. 5mg; 10mg)
A
A= adrenonegative drug, cardioselective beta1 blocker without ISA + Class 2 antiarrhytmic drug B= blocks beta1 receptors in heart and vascular smooth muscle. This results in a reduction of HR, CO, bp etc. At higher doses (>20mg) Bisoprolol may completely block beta2 receptors in bronchial and vascular smooth muscles --> bronchospasm and vasodilation. Also decreases renin levels C= angina pectoris, hypertension, tachycardia, migraine,coronary artery disease, ischemic heart diseases, prevention of MI
3
Q
Doxazosin
A
A= adrenonegative drug, selective alpha1 antagonist B= blocks selectively alpha1 receptors --> decreases systemic peripheral vascular resistance (alpha1b receptors) and induces vasodilation --> decreases bp (long lasting, 1 tab/day) also relaxes smooth muscles in urinary passages (alpha 1a receptors) C= hypertension and benign prostatic hyperplasia
4
Q
Clonidine
A
A= adrenopositive drug, selective alpha2 presynaptic receptor agonist (neurotropic drug) B= binds to and activates presynaptic alpha2 receptors --> located on cardiovascular control centers--> decreasing impulsation among sympathetic nerves from CNS--> decreasing of bp. Blood vessels--> decreased release of NE and decreasing of bp. Also binds to and activates I1 receptors (imidazoline receptors) which mediates sympathonegative actions to lower blood pressure C= hypertension, hypertensive crisis when immideate effects are not necessary. Differential diagnosis of pheochromocytoma in hypertensive patients, prophylaxis of vascular migraine headaches, ADHD. Painkiller properties, reliefs withdrawal symptoms of opioids or alcohol abuse
5
Q
Norepinephrine/Noradrenaline
A
A= adrenopositive drug, alpha and beta agonist, direct acting sympathomimetics B= stimulates alpha1, alpha2, beta1 receptors(latter to a lesser degree) and therefore acts as an peripheral vasoconstrictor and positive inotrophic effect on heart and dilator of coronary arteries as a result of its beta-adrenergic activity C= acute hypotension, cardiac arrest, septic shock, neurogenic shock
6
Q
Dopamine
A
A= adrenopositive drug, alpha and beta agonist B= activates alpha1 and beta1 receptors--> causes positive chronotropic and inotrophic effects on myocaridum --> increased HR and contractility--> due to directly activating beta adrenergic receptors and indirectly due to causing release of NE from storage sites of sympathetic neurons. In the brain dopamin acts as an agonist to be 5 receptor subtypes (d1-5) C= cardiogenic shock in infarction or cardiac surgery. Hemorrhagic shock, shock due to renal failure
7
Q
Ephedrine
A
A= adrenopositive drug, indirect sympathomimetics B= acts through the release of stored catecholamines (incl dopamine and serotonin) C= stimulate, have a stimulant effect on mood and alertness and a depressant effect on appetite. Ephedrine is utilized when prolonged duration of effect is desired, particularly after oral administration in case of nasal congestion, sinusitin and also urinary incontincence and asthma
8
Q
Phenylephrine
A
A= adrenopositive drug, direct acting selective alpha1 agonist B= binds to and activates alpha1 receptors (mainly located on peripheral blood vessels), increases peripheral arterial resistance (contraction) and decreases venous capacitance C= acute hypotension, shock, addition with anaesthetics, glaucoma, used as a nasal decongestant
9
Q
Felodipinum (tab. 2,5mg; 5mg;10mg)
A
A= antihypertensive drugs, dihydropyridine calcium channel blocker "dipins" --> vasoselective B= blocks voltage gated L-type calcium channels, decreases i/c levels of ca2+ in vascular smooth muscles, decreases contraction and cause muscle relaxation and vasodilatation (reduces vascular resistance) C= hypertension, prizmetal angina, anti arrhytmiac
10
Q
Lacidipinum
A
A= antihypertensive drugs, dihydropyridine calcium channel blocker "dipins" --> vasoselective B= blocks voltage gated L-type calcium channels, decreases i/c levels of ca2+ in vascular smooth muscles, decreases contraction and cause muscle relaxation and vasodilatation (reduces vascular resistance) C= hypertension, prizmetal angina, anti arrhytmiac
11
Q
Moxonidinum
A
A= antihypertensive drug, centrally acting alpha2-adrenergic agonist B= selectively binds to and activates imidazoline subtype 1 (I1) receptor found mainly in both rostral ventrolateral pressor and ventromedial depressor areas of medulla --> decreases sympathetic discharge --> decreases bp. Also promotes sodium excretion. C= mild to moderate hypertension
12
Q
Bosentanum
A
A= antihypertensive drug, endothelin receptor antagonist B= Endothelin-1 (ET-1) is a neurohormone, the effects of which are mediated by binding to ETA and ETB receptors in the endothelium and vascular smooth muscle. ET-1 concentrations are elevated in plasma and lung tissue of patients with pulmonary arterial hypertension, suggesting a pathogenic role for ET-1 in this disease (endothelin1 constricts pulmonary vessels). Bosentan is a specific and competitive antagonist at endothelin receptor types ETA and ETB (higher affinity to ETA) C= pulmonary artery hypertension, mild to moderate hypertension
13
Q
Enalaprilum (tab. 5mg; 10mg; 20mg)
A
A= antihypertensive drug, ACE inhibitor B= acts by blocking the ACE that normally hydrolyes angiotensin I to angiotensin II and inactivates bradykinin (plasma kininase). Blocking of ACE leads to decreased amount of angiotensin II and increased amount of bradykinin(vasodilator) -->vasodilation and inhibition of aldosterone secretion (reduces peripheral vascular resistance and decreases sodium and water retention) --> decreases bp C= Hypertension, heart failure, myocardial infarction, left ventricular dysfunction, diabetic nephropathy, renal protector
14
Q
Perindoprilum (tab. 2mg; 4mg)
A
A= antihypertensive drug, ACE inhibitor B= acts by blocking the ACE that normally hydrolyes angiotensin I to angiotensin II and inactivates bradykinin (plasma kininase). this leads to decreased amount of angiotensin II and increased amount of bradykinin(vasodilator) -->vasodilation and inhibition of aldosterone secretion (reduces peripheral vascular resistance and decreases sodium and water retention) --> decreases bp C= Hypertension, heart failure, myocardial infarction, left ventricular dysfunction, diabetic nephropathy, renal protector
15
