The drug Amzaar
The safety of Amzaar was evaluated in clinical trials for 8 weeks with the participation of 646 patients with AH, of which 325 patients took combination therapy amlodipine + losartan. In the course of clinical studies, the following adverse events were observed, which were evaluated by the investigators as possible, probably or definitely associated with taking the drug (frequent> 1% and <10%, infrequent> 0.1% and <1%).
From the nervous system Frequent: dizziness, headache. Infrequent: drowsiness.
General disorders Infrequent: weakness, discomfort in the chest, chest pain, a sense of rapid saturation, peripheral edema.
From the gastrointestinal tract Infrequent: abdominal discomfort, dyspepsia, nausea, reflux esophagitis.
From the skin and subcutaneous tissue Infrequent: itchy skin (generalized), urticaria (generalized).
From the heart Infrequent: a feeling of palpitations.
From the side of the vessels Infrequent: "tides" of blood to the skin of the face, orthostatic hypotension.
On the part of the respiratory system, the organs of the thorax and the mediastinum Infrequent: shortness of breath.
From the side of the hearing organ and labyrinthine disorders Infrequent: vertigo.
From the side of the kidneys and urinary tract Infrequent: pollakiuria.
The following undesirable phenomena were observed when using the active substances included in the preparation Amsaar in monotherapy.
Losartan
Because clinical trials are conducted under different conditions, the frequency of adverse reactions observed in clinical studies of a single drug can not be directly compared with the frequency of adverse reactions observed in clinical studies of another drug and it can not reflect the frequency observed in clinical practice.
Generally losartan well tolerated by patients with AH. Adverse events are mild and transient and do not require withdrawal of therapy. The total incidence of adverse events with losartan is comparable to that for placebo. In controlled clinical trials, the frequency of discontinuation of therapy due to clinically significant adverse events was 2.3% in the group of patients taking losartan, and 3.7% in the group of patients taking placebo. In controlled clinical trials of losartan in patients with hypertension, the only undesirable treatment-related response observed more often than with placebo was dizziness observed in treatment groups with losartan at a frequency of 1% or more.In addition, less than 1% of patients had dose-dependent orthostatic reactions. Rarely (> 0.01% and <0.1% of cases) reported skin rash, but the incidence was less than with placebo.
In double-blind, controlled clinical trials,> 1% of patients with AH experienced the following adverse events with losartan (n = 2085) or placebo (n = 535), regardless of their association with treatment.
General disorders: pain in the stomach area of 1.7% (placebo 1.7%); weakness and fatigue 3.8% (3.9%); chest pain 1.1% (2.6%); peripheral edema 1.7% (1.9%).
From the cardiovascular system: a palpitation of 1.0% (placebo 0.4%); tachycardia 1.0% (1.7%).
From the digestive system: diarrhea 1.9% (placebo 1.9%); indigestion 1.1% (1.5%); nausea 1.8% (2.8%).
From the musculoskeletal system: back pain 1.6% (placebo 1.1%); muscle spasms 1.0% (1.1%).
From the central nervous system: dizziness 4.1% (placebo 2.4%); headache 14.1% (17.2%); insomnia 1,1% (0,7%).
From the respiratory system: cough 3.1% (placebo 2.6%); edema of the nasal mucous membrane 1.3% (1.1%); pharyngitis 1.5% (2.6%); Sinusitis 1.0% (1.3%); upper respiratory tract infection 6.5% (5.6%).
Controlled clinical studies have shown that losartan mainly well tolerated by patients with hypertrophy and left ventricular hypertrophy. The most frequent undesirable reactions associated with the use of losartan were systemic and non-systemic dizziness, asthenia / weakness.
In this study, in patients without diabetes mellitus, the incidence of new cases of diabetes was lower with losartan compared to atenolol (p <0.001). Since there was no placebo group in this study, it is not known whether this is a positive effect of losartan or an undesirable phenomenon of atenolol.
Controlled clinical studies have shown that losartan mainly well tolerated by patients with type 2 diabetes and proteinuria. The most frequent adverse reactions associated with the use of losartan were dizziness, asthenia / weakness, marked decrease in blood pressure and hyperkalemia (see SPECIAL INSTRUCTIONS).
The following undesirable reactions were observed in clinical practice during post-marketing period.
Hypersensitivity reactions: in patients taking losartan, anaphylactic reactions, angioedema with involvement of the larynx and pharynx causing airway obstruction, and / or angioedema of the face, lips, throat and / or tongue were rarely observed. Some of these patients had a history of angioneurotic edema following the administration of other drugs, including ACE inhibitors. Rarely reported on the occurrence of vasculitis, including purple Shenlaine-Genoh.
From the digestive system: hepatitis (rarely), a violation of the liver, vomiting.
General disorders: a feeling of general discomfort.
On the part of the blood system: anemia, thrombocytopenia (rarely).
From the musculoskeletal system: myalgia, arthralgia.
From the central nervous system: migraine, dysgeusia.
From the genitals and the breast: erectile dysfunction / impotence. From the respiratory system: cough.
From the skin: urticaria, itching, redness of the skin, photosensitization.
Amlodipine besylate
Since clinical trials are conducted under different conditions, the frequency of adverse reactions,observed in clinical studies of a single drug, can not be directly compared with the frequency of adverse reactions observed in clinical studies of another drug, and it can not reflect the frequency observed in clinical practice.
The safety of amlodipine besylate has been evaluated in clinical trials involving more than 11,000 patients. In general, treatment with amlodipine besylate in a dosage of up to 10 mg once a day was well tolerated. The majority of undesirable phenomena observed during amlodipine besylate therapy were of mild or moderate severity. In controlled clinical trials that directly compare amlodipine besylate therapy at a dosage of up to 10 mg once daily from placebo, amlodipine besylate therapy was withdrawn because of adverse events in only 1.5% of patients, which is not significantly different from the placebo group (about 1 %). The most frequent (> 1% and <10%) adverse events are headache and swelling.
The following frequency (%) of dose-dependent undesirable events was observed:
Unwanted phenomenon | 2.5 mg | 5.0 mg | 10.0 mg | Placebo |
Edema | 1,8 | 3,0 | 10,8 | 0,6 |
Dizziness | 1,1 | 3,4 | 3,4 | 1,5 |
Tides | 0,7 | 1,4 | 2,6 | 0,0 |
Heart palpitations | 0,7 | 1,4 | 4,5 | 0,6 |
Other adverse events that were observed in the placebo-controlled clinical trials of more than 1.0% of patients and did not have a clear link with the dose:
Unwanted phenomenon | Amlodipine besylate (%) | Placebo (%) |
Headache | 7,3 | 7,8 |
Increased fatigue | 4,5 | 2,8 |
Nausea | 2,9 | 1,9 |
Abdominal pain | 1,6 | 0,3 |
Drowsiness | 1,4 | 0,6 |
Some adverse events appears to be associated with taking amlodipine besylate and dose were more common in women than in men:
Undesirable | Amlodipine besylate | Placebo |
phenomenon | Men (%) | Women (%) | Men (%) | Women (%) |
Edema | 5,6 | 14,6 | 1,4 | 5,1 |
Tides | 1,5 | 4,5 | 0,3 | 0,9 |
Feeling palpitation | 1,4 | 3,3 | 0,9 | 0,9 |
Drowsiness | 1,3 | 1,6 | 0,8 | 0,3 |
The following undesirable phenomena are often (>0,1% and < 1%) observed in patients treated in controlled clinical trials or in the open research environment or in the post-registration period, applications where a causal relationship is unknown (indicated in order to inform about a possible causal relationship):
From the cardiovascular system: arrhythmia (including ventricular tachycardia and atrial fibrillation), bradycardia, chest pain, marked reduction in blood pressure, ischemic peripheral vascular disease, syncope, tachycardia, postural dizziness, postural hypotension, vasculitis.
From the central and peripheral nervous system: hypoesthesia, peripheral neuropathy, paresthesia, tremor, vertigo.
From the digestive system: anorexia, constipation, dyspepsia *, dysphagia, diarrhea, flatulence, pancreatitis, vomiting, gingival hyperplasia.
General disorders: allergic reaction, asthenia *, back pain, "tides" of blood to the skin of the face, malaise, pain, stiffness, weight gain, weight loss. From the side of the musculoskeletal system: arthralgia, arthrosis, muscle cramps *, myalgia.
Disorders of the psyche: sexual dysfunction (in men and women), insomnia, increased excitability, depression, unusual dreams, anxiety, depersonalization.
From the respiratory system: shortness of breath *, nosebleeds.
From the skin: angioedema, erythema multiforme, skin itch *, skin rash *, erythematous rash, maculopapular rash.
From the sense organs: impaired vision, conjunctivitis, diplopia, pain in the eye, ringing in the ears.
From the urinary system: frequent urination, impaired urination, nocturia.
From the side of the autonomic nervous system: dryness of the oral mucosa, increased sweating.
From the side of metabolism and nutrition: hyperglycemia, thirst.
From the hematopoiesis: leukopenia, purpura, thrombocytopenia.
* These adverse events were observed in less than 1% in placebo-controlled studies, but their incidence was from 1% to 2% in all studies with repeated use of amlodipine.
The following undesirable phenomena were observed very rarely (<0.1%): heart failure, rhythm disturbances, extrasystole, skin depigmentation, urticaria, dry skin, alopecia, dermatitis, muscle weakness, muscle twitching, ataxia, increased blood pressure, migraine, and moisture of the skin, apathy, agitation, amnesia, gastritis, increased appetite, frequent unformed stool, cough, rhinitis, dysuria, polyuria, parosmia, taste disorder, accommodation disorder and xerophthalmia.
Other adverse events have been observed sporadically, and it is impossible to establish a causal relationship with medication or concomitant diseases, such as myocardial infarction and angina pectoris.
The following undesirable phenomena were also observed in the post-marketing period of observation.Since these unwanted reactions were obtained voluntarily from a population of unknown size, it is not always possible to establish their frequency reliably or to establish a cause-and-effect relationship with the taking of the drug. An undesirable phenomenon that was rarely observed in the post-registration period of observation without an established cause-effect relationship: gynecomastia. During post-registration period of observation, amlodipine besylate received jaundice and increased activity of "hepatic" enzymes (mostly caused by cholestasis or hepatitis), in some cases quite severe and requiring hospitalization.
Amlodipine besylate was safely used in patients with chronic obstructive pulmonary disease, compensated for chronic heart failure, coronary artery disease, peripheral arterial disease, diabetes mellitus, and lipid profile disorder.
Laboratory indicators
The drug Amzaar
In some patients, at 8 weeks of simultaneous administration of amlodipine and losartan, palpitation decreased, but it was not clinically significant.
Some patients showed an increase in creatinine in the blood and an increase in the activity of "liver" enzymes, but no specific laboratory monitoring is required.
Losartan
In controlled clinical trials in patients with hypertension, clinically significant changes in baseline laboratory indicators were rarely associated with losartan. In 1,5% of patients, hyperkalemia was observed (serum potassium more than 5.5 meq / l). In a clinical study in patients with type 2 diabetes mellitus with proteinuria, hyperkalemia developed in 9.9% of patients taking losartan, and 3.4% of patients taking placebo (see SPECIAL INSTRUCTIONS). Increased activity of alanine aminotransferase (ALT) was observed in rare cases and usually returned to normal after the abolition of therapy.
Amlodipine
There were no clinically significant changes in standard laboratory indicators associated with amlodipine therapy. There were no clinically significant changes in serum potassium levels, serum glucose concentrations, triglyceride concentrations, total cholesterol, high-density lipoprotein cholesterol, uric acid, blood urea nitrogen, or creatinine.
