1- CLINICAL PHARMACY IN CARDIOLOGY
2FREQUENCY of arterial hypertension (AH)AP gt
140/90 mm Hg
- 20-30 in population
- At elderly people - 45-50
3Principles 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.
4Treatment of arterial hypertension Drugs of
first row -diuretics (furosemid, dichlothiazide,
spironolacton) -inhibitors of ACE
(captopril, enalapril, ramipril) -antagonists of
angiotesine II receptors (?R? ??)

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)
5Mechanism 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
6FUROSEMIDE
- 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
7THIAZIDES and RELATED DIURETICS
- Medium efficacy diuretics

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)

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

first dose), tolerance gradually develops with
monotherapy

antioxidant/free radical scavenging properties,
it is used for HD and for CHF
21MECHANISM 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
22IACE (ANGIOTENSIN CONVERTING ENZYME INHIBITORS)

- 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)
23PERINDOPRIL (IACE)
24KOZAAR (Losartan) ?R? ??

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

beta-adrenoreceptors in heart, which leads to
increasing of systolic volume after 8-10 weeks of
regular administration (paradox of
