Patients, the in the pre-menopausal period with no ovulation
When using rosiglitazona in women who are in the pre-menopausal period,there is hormonal imbalance, but no significant adverse events associated with menstrual irregularities are observed. In the event of a menstrual cycle, it is necessary to assess the possible risk and the expected benefits of continuing treatment. Due to increased sensitivity to insulin, rosiglitazone therapy in patients with insulin resistance and anovulatory cycle in the premenopause (for example, in patients with polycystic ovary syndrome) may result to the resumption of ovulation and the risk of pregnancy.
Increase in total cholesterol concentration
The increase in the total cholesterol concentration is associated with an increase in both LDL and HDL, and the ratio of total cholesterol to HDL is not changed.
Anemia
Treatment with rosiglitazone was associated with a dose-dependent decrease in hemoglobin concentration. Patients with low hemoglobin content prior to initiation of therapy are at increased risk for developing anemia with rosiglitazone treatment.
Fluid retention and heart failure
Thiazolidinediones can cause fluid retention in the body,which can aggravate or promote the development of symptoms of heart failure.
Rosiglitazone can cause a dose-dependent fluid retention in the body. It is necessary to take into account the possible value of fluid retention in weight gain. All patients, especially those receiving combination therapy with insulin or sulfonylureas, and with a risk of developing heart failure, should be observed for the development of adverse events associated with fluid retention, including weight gain and heart failure. Increased attention is required by patients receiving a combination of rosiglitazone with metformin and insulin.
Rosiglitazone It is necessary to cancel if there are signs of heart failure. After starting therapy with rosiglitazone and during the titration of the dose, careful medical monitoring of the patient's condition with regard to the following symptoms and signs of heart failure is necessary: rapid and excessive weight gain, dyspnea and / or swelling. With the development of symptoms of heart failure, rosiglitazone should be discontinued and therapy prescribed in accordance with current standards for the treatment of heart failure.
The drug is contraindicated in patients with heart failure of I-IV functional class according to the NYHA classification (New York Heart Association), including in the history.
Patients with acute coronary syndrome (ACS) were not included in the clinical studies. The appointment of rosiglitazone, as well as other oral hypoglycemic drugs, is not recommended for ACS, especially taking into account the increased risk of developing heart failure in ACS. During the acute phase, rosiglitazone should be withdrawn.
The incidence of heart failure was more often reported in patients with a history of heart failure, the incidence of edema and heart failure was also more commonly reported in elderly patients and patients with mild or moderate renal failure. Given the limited experience with rosiglitazone in patients older than 75 years, caution should be exercised in patients of this age group.
Myocardial ischemia
A retrospective analysis of 42, mostly short-term clinical trials, suggests a link between rosiglitazone intake and the risk of developing myocardial ischemia in placebo-controlled studies, but not in comparison with active drugs.In the same analysis, when comparing rosiglitazone with other oral hypoglycemic drugs, there were no differences in the incidence of cardiovascular complications. The relationship between rosiglitazone intake and the risk of ischemia is not established. An increased risk of developing myocardial ischemic damage was observed in patients who received nitrate therapy initially or during a clinical study for established CHD.
Rosiglitazone It is not recommended to use in patients receiving concomitant therapy with nitrates.
At present, there is no reliable data on the reduction of the risk of macrovascular complications in patients with type 2 diabetes with oral hypoglycemic drugs, including thiazolidinediones.
Since in patients with type 2 diabetes, the risk of developing coronary artery disease is increased regardless of the choice of an oral hypoglycemic drug, appropriate measures should be taken to reduce the risk of developing cardiovascular complications.
Visual impairment
There are rare reports of the development or deterioration of diabetic macular edema with reduced visual acuity.Such patients often reported the development of peripheral edema. In some cases, such violations were resolved after the abolition of therapy. It should be borne in mind the possibility of developing this complication with complaints of the patient to reduce visual acuity.
Hypoglycaemia
It is possible to develop hypoglycemia associated with the combined use of rosiglitazone and sulfonylurea derivatives, which may require a reduction in the dose of the concomitant drug.
Effect on the condition of bone tissue
In a comparative study of glycemic control lasting 4-6 years ("ADORT" - "Study of outcomes of diabetes progression") with the use of rosiglitazone monotherapy in patients who had not previously received treatment, who was recently diagnosed with type 2 diabetes, there was an increase in the incidence of bone fractures among women. During the 4-6 year period, the incidence of fractures in women taking
rosiglitazone, was 9.3% (60/645) compared with 3.5% (21/605) in women taking
glibenclamide, and from 5.1% (30/590) in women taking
metformin. Most of the reported messages in the rosiglitazone group concerned fractures of the upper limbs and distal fractures of the lower extremities.This localization of fractures differs from that usually observed in postmenopausal osteoporosis (for example, proximal femur or spine). Other studies show that the risk of bone fractures can also exist in men. Nevertheless, the risk of fractures in women is obviously higher than that of men.
In women, an increase in the incidence of fractures was recorded after the first year of use and subsequent application for a long period. When rosiglitazone is prescribed, especially for women, a possible increase in the risk of fractures should be taken into account. It is necessary to monitor bone mineral density (BMD).
In several studies in men and women taking
rosiglitazone, cases of a slight decrease in BMD in the spine and femur were recorded. Correlations between changes in BMD and risk of fractures have not been established.
Simultaneous prescribing with other drugs (see also section "Interaction with other drugs" medicinal preparations ")
With simultaneous administration with inhibitors or inductors СUR2С8, careful monitoring of blood glucose and correction of rosiglitazone dose may be required.
Monitoring of liver function
In the course of routine practice, rare reports of liver damage were recorded. Data on the use of rosiglitazone in patients with increased activity of "hepatic" enzymes (ALT 2.5 times higher than the upper limit of the norm) are limited. Thus, before the beginning and periodically during treatment, depending on the clinical picture, all patients should be monitored for activity of "liver" enzymes. Treatment with rosiglitazone does not begin with an increase in the activity of "liver" enzymes, 2.5 times higher than the upper limit of the norm (VGN), or in the presence of any sign of liver disease. At excess of VGN more than 3 times on a background of treatment it is necessary to make a repeated estimation of indicators as soon as possible. In the event that the values remain exceeding the VGN 3 times, treatment with rosiglitazone is stopped. In the case of developing symptoms suggestive of liver dysfunction, such as unexplained nausea, vomiting, abdominal pain, fatigue, anorexia and / or darkening of urine, it is necessary to evaluate the activity of "liver" enzymes. The decision to continue therapy with rosiglitazone should be based on the clinical picture and laboratory data.When jaundice appears, treatment with rosiglitazone should be discontinued.
Patients with impaired renal function
With renal failure of mild to moderate severity, dose adjustment is not required. With regard to the use of the drug in patients with severe renal insufficiency, the data is insufficient, so the drug should be used with caution.
