Title: CLINICAL PHARMACY IN CARDIOLOGY


1
  • CLINICAL PHARMACY IN CARDIOLOGY

2
FREQUENCY of arterial hypertension (AH)AP gt
140/90 mm Hg
  • 20-30 in population
  • At elderly people - 45-50

3
Principles of treatment of arterial hypertension
1. Treatment should be started as soon as
possible and should be hold till the end of life.
Canceling antihypertensive drugs administration
causes relapse of AH. 2. All the individuals with
increased arterial pressure should obtain
drugless treatment (modifying lifestyle)
-rejection from smoking and alcohol -in
creasing of physical activity -restriction
of salt consumption (less than 6 g per
day) -decreasing of body weight in a case
of obesity. 3. Scheme of drug treatment should
be the most availably simple 1 tablet per day
if possible it is better to use drugs with long
duration of action (prophylaxis of considerable
fluctuation of blood pressure during the day). 4.
Rapid decreasing of blood pressure to low figures
is dangerous, especially for elderly patients. 5.
Main aim of the treatment is to decrease blood
pressure to 140/90 mm Hg. To improve life
prognosis is the aim that has a more significant
meaning than character of drugs used to reach
this aim. It is better to prescribe cheap and
non modern drugs than dont treat the patient
at all.
4
Treatment of arterial hypertension Drugs of
first row -diuretics (furosemid, dichlothiazide,
spironolacton) -inhibitors of ACE
(captopril, enalapril, ramipril) -antagonists of
angiotesine II receptors (?R? ??)
(losartan) -ß-adrenoblockers (anaprilin,
atenolol, thymolol) -a-adrenoblockers
(prasosine, terasosine) -a-, ß-adrenoblockers
(labetolol, carvedilol) -Ca ions antagonists
(niphedipine, amlodipine, verapamil) Drugs of
second row -agonists of a2 adrenoreceptors of
central action (clopheline, methyldopa) -sympathol
ytics (reserpin, octadin) -direct vasodilators
(molsidomin, hydralasin) New drugs -imidasolines
(moxonidine, rilmenidine) -serotonin receptors
blockers (ketanserin) -monateril (calcium
antagonist, a2 -adrenoblocker)
5
Mechanism of action of thiaside diuretics in case
of arterial hypertension
Dychlothiaside (hypothiaside)
Oxodolin (chlortalidon, hygroton)
Thiaside diuretics
Holding sodium and water
Volume of circulating blood
Peripheral vascular resistance
Cardiac output
Decreasing of arterial pressure
6
FUROSEMIDE
  • High ceiling (loop) diuretic
  • Properties
  • 1. diuretic action
  • 2. dilation of peripheral venous
  • 3. decrease left ventricular filling pressure
  • 4. potent anti-inflammatory effect (similar to
    indometacine and other NSAID)
  • Administration hypertensive emergencies,
    long-term treatment of arterial hypertension
  • Adverse reactions dehydration, hypokalemia,
    hearing loss - deafness, hypocalcaemia

7
THIAZIDES and RELATED DIURETICS
  • Medium efficacy diuretics
  • Benzothiadiazines (chlorothiazide,
    hydrochlorothiazide, clopamide), related thiazide
    like (chlorthalidone, indapamide)
  • for long-term treatment of arterial hypertesion
    (oral administration)
  • Duration of action (6-12 hours for
    hydrochlorothiazide, 12-18 hours for clopamide,
    48-50 hours for chlorthalidone)
  • Adverse reactions dehydration, hypokalemia,
    hyperuricaemia (rise of blood urate level)

8
Furosemid (diuretic)

Furosemid (diuretic)
10
TORASEMID
11
Mechanism of action of beta-adrenoblockers (anapri
lin, atenolol, methoprolol etc.) in case of
arterial hypertension
ß- adrenoblockers
activation of
ß1-adrenoreceptors of
heart
Cardiac output
Decreasing of blood pressure
Peripheral resist- ance of vessels
Angiotensine ??
Renin
Aldosterone
Holding sodium and water
Volume of
blood circulation
12
ß-adrenoblockers
  • Used for mostly mild to moderate cases of AH
    (frequently in combinations with other drugs)
  • Stable hypotensive response develops over
    1-3 weeks
  • Titration the effective dose
  • Antihypertensive action is maintained over
    24 hr after single daily dose
  • Withdrawal syndrome if discontinue quickly
  • Contraindications bronchial asthma, peripheral
    vascular disease, diabetes

13
Atenolol ß - adrenoblocker
14
Anaprilin ß1- ß 2 adrenoblocker
15
Vasocardin 100 mgMethoprolol tartrate
16
Nadolol( ß1, ß 2 - adrenoblocker )
17
Tenoretic(atenolol chlortalidon)
18
a1-adrenergic blockers(prazosin, terazosin,
doxazosin)
  • Do not block presynaptic a2-adreno-receptors, so
    do not cause reflex cardiac stimulation (as
    compared to nonselective a-adrenoblockers)
  • Dilate resistance and capacitance vessels
  • Adverse effects postural hypotension (effect of
    first dose), tolerance gradually develops with
    monotherapy

19
Prasosine (a1 adrenoblocker)
20
a, ß adrenoreceptors blockers(labetalol,
carvedilol)
  • Labetalol is used for long-term treatment of AH
    and for emergencies (i. v. - hypertensive
    crisis, clonidine withdrawal, cheese reaction)
  • Carvedilol produces vasodilatation,
    antioxidant/free radical scavenging properties,
    it is used for HD and for CHF

21
MECHANISM OF ACTION OF IACE
ANGIOTENSINOGEN
sympathetic tone
Renin (kidneys)
ANGIOTENSIN (inactive)
Decrease of arterial pressure
peripheral vessels tone
Decrease angiotensine II production
retention of Na and H2O
ACE
Decrease aldosterone production
-
bradicinine
IACE
22
IACE (ANGIOTENSIN CONVERTING ENZYME INHIBITORS)
  • Captopril, enalapril, ramipril, perindopril etc.
  • Decrease the levels of mortality and morbidity
  • When used for monotherapy control AP in 50 of
    patients
  • Frequently combined with diuretics (not with
    potassium-sparing diuretics !) and
    ß-adrenoblockers - the effectiveness of therapy
    grows to 90
  • Adverse effects cause the retention of potassium
    ions, dry persistent cough (requires
    discontinuation of IACE or treatment with NSAID)
  • Contraindicated for the patients with bilateral
    renal artery stenosis)

23
PERINDOPRIL (IACE)
24

    mortality as a result of reinfarction (long term
    controlled trials)
  • Retard forms of DHPs (Amlodipine) are used widely
    for AH
  • Do not contraindicated in asthma, do not impair
    renal perfusion, do not affect male sexual
    function
  • Can be used during pregnancy
  • Can be given to diabetics
  • Adverse reactions ankle edema, slight negative
    inotropic / dromotropic action, nifedipine
    decreases insulin release (diabetes accentuating)

39
Factors which promote developmentINTOXICATION
WITH HEART GLYCOZIDES
  • Digitoxin is a choice drug when HI is combined
    with kidney insufficiency, but contraindicated
    if liver is damaged (it is metabolized by liver)
  • Digoxin is not contraindicated even in case of
    liver cirrhosis (it is not metabolized in liver),
    but contraindicated in case of kidney
    insufficiency (it is excreted by kidneys)
