Drugs Mode of action Side effects
Hypertension
Angiotensin converting Inhibits the conversion of Side effects:
enzyme inhibitor (ACEi) angiotensin I-> II (which prevent - Hypotonia
- Captopril the vasoconstriction) - Coughing
- Enalapril - Hyperkalemia
- (pril) - Acute kidney failure
- Angioneurotic oedema
- Fetoxicity

Contraindications:
- Bilateral renal artery
stenosis
- Primary
hyperaldosteronism
- Angio-oedema
- Pregnancy
Interactions: K+diuretics,
digoxin, lithium, NSAID
Angiotensin receptor blocker Blocks AT1 receptors in brain, Similar ACEi (except of cough)
(ARB) -sartan family: vessels and adrenal gland.
Candesartan
Ibersartan Vasodilation, reduced
Olmesartan aldosterone and ADH
(vasopressin) secretion, reduced
cardiac hypertrophy
Calcium antagonist (increased Relaxation of smooth muscle of Contraindications:
resistance all) arteries and coronary vessels - Hypotonia
- Heart failure (mainly
Dihydropyridine: nifedipine, Reduction of blood pressure, verapamil, diltiazem)
nitrendipine, felodipine and reduction of afterload, - Unstable angina pectoris
amlodipine spasmolytic effects on coronary (relative)
vessels.
Phenylalkylamine: verapamil
and gallopamil (also Inhibition of L-type Ca2+
increased CO) channels binding to a1 subunit

Benzothiazepine: diltiazem
(increased cardiac output)
Nifedipine -Rapid relaxation of vascular SE: do effect baroreceptor
smooth arterial muscle cells reflex (blood pressure drop->
(starting at arterioles) increase BP)
- Blood pressure/afterload
decrease All calcium antagonist
- Cardiac wall tension/O2 - Hypotonia
consumption - Heart failure (mainly
-Dilation of coronary vessels verapamil, diltiazem)
-Barely any direct effects on the - Unstable angina pectoris
myocardium (relative)

Mode of action:
Inhibition of cardiac> vascular L-
type calcium channels

,Verapamil Inhibition of cardiac> vascular L- Increase Frequency heart and
type calcium channels AV conduction due to
- Inhibition of SA node baroreceptor
- AV conduction decrease
- Inhibition of late Na - Arterial hypertonicity
potentials - Coronary sclerosis-
- Myocardial contractility dependent angina
decrease - Vasospastic angina
(diltiazem)
- Supraventricular
tachyarrhythmia
SE: bradycardia, AV blockade,
negative inotropic effects (HF)

- Hypotonia
- Heart failure (mainly
verapamil, diltiazem)
- Unstable angina pectoris
(relative)

- II and III AV block
- Sick sinus syndrome
- Bradycardia - -Receptor
blockade (mainly verapamil)
- Increased digoxin levels
(verapamil)

Indications:
- Arterial hypertonicity
- Vasospastic angina
(Prinzmetal‘s)
- Chronic stable angina
(amlodipine)
- Hypertensive
emergency (nifedipine)
- Raynaud‘s syndrome

Diltiazem - Inhibition of cardiac and - Arterial hypertonicity
vascular calcium - Coronary sclerosis-
channels dependent angina
- Cardiac/vascular organ - Vasospastic angina
selectivity in between (diltiazem)
compounds of the PAA - Supraventricular
and DHP types tachyarrhythmia
SE: bradycardia, AV blockade,
negative inotropic effects (HF)

- Hypotonia
- Heart failure (mainly
verapamil, diltiazem)
- Unstable angina pectoris
(relative)

- II and III AV block
- Sick sinus syndrome
- Bradycardia - -Receptor
blockade (mainly verapamil)
- Increased digoxin levels

, (verapamil)


B-blockers (metoprolol) Blocks beta receptor Cardiac:
- Bradycardias / disorders of
AV conductivity
- Worsening of heart failure
symptoms

Non-cardiac:
- Vasoconstriction / cold
feeling in the extremities
- Ischaemias
- Bronchoconstriction
- Worsening of prediabetic /
diabetic metabolism
- Obscuring hypoglycaemia
- Fatigue
- Sleep disorders…
