According to the World Health Organization (WHO)
the undesirable effects are classified according to their frequency of development as follows: very often (> 1/10), often (> 1/100, <1/10), infrequently (> 1/1000, <1/100), rarely (> 1/10000, <1/1000), very rarely (<1/10000), the frequency is unknown (the frequency of occurrence of phenomena can not be determined byaccessing existing data).
From the side of the cardiovascular system
often: marked decrease in blood pressure, violation of orthostatic regulation of vascular tone (orthostatic hypotension), syncopal conditions;
infrequently: orthostatic collapse, myocardial ischemia, including the development of an attack of angina or myocardial infarction, impaired cerebral circulation (due to a sharp fall in blood pressure in patients at risk), tachycardia, arrhythmia, peripheral edema, palpitation, "flushes" of blood to the skin of the face;
rarely: occurrence or strengthening of circulatory disorders against the background of stenosing vascular lesions, vasculitis;
frequency is unknown: Raynaud's syndrome.
On the part of the organs of hematopoiesis infrequently: eosinophilia; rarely: leukopenia, including neutropenia and agranulocytosis (neutropenia and agranulocytosis are reversible and disappear with the abolition of ACE inhibitors), anemia, thrombocytopenia, lymphadenopathy, a decrease in hemoglobin;
frequency is unknown: oppression of bone marrow hematopoiesis, pancytopenia, hemolytic anemia.
From the nervous system
often: weakness, headache; infrequently: mood lability, anxiety, nervousness, paresthesia, dizziness, sleep disorders, insomnia, motor
anxiety;
rarely: tremor, imbalance, confusion;
frequency is unknown: cerebral ischemia, including stroke and transient impairment of cerebral circulation, parosmia (impaired perception of odors),
violation of psychomotor reactions, violation of concentration of attention.
From the sense organs
infrequently', visual disorders, including vagueness of the image, a violation of taste sensations;
rarely: conjunctivitis, hearing impairment tinnitus (sensation of ringing, noise in the ears).
From the respiratory system often: "dry" cough, bronchitis,
sinusitis, dyspnea; infrequently: bronchospasm, includingseverity of the course of bronchial asthma, congestion of the nose.
From the digestive system
often: inflammatory reactions in the stomach and intestines, digestive disorders, abdominal discomfort, dyspepsia, diarrhea, nausea, vomiting; infrequently: pancreatitis, increased activity of "liver" transaminases and conjugated bilirubin concentration in blood plasma, increased activity of pancreatic enzymes, intestinal angioedema, abdominal pain, gastritis, constipation, dryness of the oral mucosa;
rarely: glossitis; Cholestatic jaundice, hepatocellular lesions;
frequency is unknown: aphthous stomatitis (inflammatory reaction of the oral mucosa), acute liver failure, cholestatic or cytolytic hepatitis, incl. with a lethal outcome.
From the urinary tract rarely: impaired renal function, including the development of acute renal failure, increased allocation of urine, the enhancement of pre-existing proteinuria,increase in the concentration of urea and creatinine in the blood.
From the skin and mucous membranes often: skin rash, in particular maculopapular;
Mr.Often: angioedema, including fatal outcome (laryngeal edema can cause airway obstruction leading to death), skin itching, hyperhidrosis (increased sweating);
rarely: exfoliative dermatitis, urticaria, onycholysis (exfoliation of the nail from the soft tissues of the finger); rarely: photosensitivity reaction; frequency is unknown: toxic epidermal necrolysis, Stevens-Johnson syndrome, erythema multiforme, pemphigus (blistering rash), weight gain of psoriasis, psoriasis-like dermatitis, pemphigoid or lichenoidal exanthema or enanthema, alopecia.
From the side of the musculoskeletal system
often: muscle cramps, myalgia;
infrequently: arthralgia.
From the side of metabolism
hasto: increase of potassium content in blood;
infrequently: anorexia, decreased appetite;
frequency is unknown: the content of sodium in the blood.
From the immune system frequency is unknown:
anaphylactic or anaphylactoid reactions, an increase in the titer of antinuclear antibodies.
From the endocrine system frequency unknown: syndrome inadequate secretion of an antidiuretic hormone (SAN ADH).
From the side of the reproductive system
infrequently: transient impotence due to erectile dysfunction, decreased libido;
frequency unknown: gynecomastia.
General disorders and disorders at the site of administration
often: pain in the chest, increased fatigue; infrequently: fever; rarely: asthenia.
