Nowadays, there is an increasing necessity to use a lot of medical products (MP) in one patient. This can lead to potential nephrotoxic adverse reactions (ADRs) among drugs. One of drug-induced kidney damage manifestations is acute tubular necrosis (ATN), which causes the development of severe complications associated with the use of hemodialysis and a high risk of mortality. The purpose of this review is to analyze literature data concerning groups of drugs and individual drugs, the intake of which is associated with the development of drug-induced ATN, risk factors, prevention and treatment methods. Among drug-induced ATN development risk factors are both general, associated with the development of drug-induced acute kidney damage (for example, age, history of chronic kidney disease, etc.), and specific ones, typical for certain groups of drugs. Most often, drug-induced ATN develops while taking antibacterial, antiviral and anticancer drugs. The main method of treatment for drug-induced ATN is abolition of nephrotoxic drugs, but if it is impossible, then there are certain patient management schemes. To prevent and to diagnose drug-induced ATN at early stages, that is the key for favorable prognosis, it is necessary to aware of doctors of different specialties about such pharmacotherapy complications.

Cardiovascular diseases are the leading cause of death both in the world and in the Russian Federation. The most significant contributors to the increase in mortality are arterial hypertension (AH) and ischemic heart disease (IHD). Dihydropyridine calcium channel blockers (CCBs) are the first line of treatment for these conditions. This is noted in the clinical guidelines for the diagnosis and treatment of AH and in the guidelines for the management of patients with chronic coronary syndromes. CCBs are a heterogeneous group of drugs that have both general and individual pharmacokinetic and pharmacodynamic properties. They are used in patients with AH and/or IHD, including those with concomitant diseases (diabetes mellitus, chronic kidney disease, bronchial asthma, chronic obstructive pulmonary disease, peripheral arterial disease). Felodipine is one of the CCBs. It has a combination of clinical effects, allowing the drug to be prescribed as a first-line therapy for AH, IHD and a combination of these diseases. This is noted in the registered indications for its use. This CCB has a sufficient evidence base of clinical trials demonstrating not only good antihypertensive and antianginal potential of the drug, but also the nephroprotection and cerebroprotection properties. The nephroprotective effect of felodipine is associated with a slowdown in the progression of chronic kidney disease, and the cerebroprotective effect is associated with a decrease in the risk of stroke and an improvement in cognitive functioning. The safety profile of felodipine is favorable: peripheral edema develops much less frequently. This is confirmed by the results of comparative studies. Felodipine is recommended for a wide range of patients with AH, IHD and their combination due to such clinical and pharmacological properties.

Among the causes of acute interstitial nephritis, drug-induced acute interstitial nephritis accounts for 50 to 78 % of all cases. Th e review summarizes the literature data on drugs that cause acute interstitial nephritis. Search in eLibrary databases.RU, PubMed®, MEDLINE, EMBASE, manuals and guidelines, materials of adverse drug reactions databases, instructions for the medical use of drugs. it was held until October 2020. Th e most probable mechanisms of its development are considered. Most attention is paid to non-steroidal anti-infl ammatory drugs, anticoagulants, antibiotics, antitumor drugs (immune checkpoint inhibitors), which are widely used in clinical practice. Th e symptoms of drug-induced acute interstitial nephritis are variable and oft en non-specific; therefore, a kidney biopsy is required for an accurate diagnosis. The main direction of treatment of drug-induced acute interstitial nephritis is the cancellation of nephrotoxic drugs, if this condition is not feasible and/or the duration of acute interstitial nephritis is less than 3 weeks, the biopsy has minimal interstitial fibrosis and there are no serious contraindications, then the possibility of using it should be considered.

The following article provides the latest recommendations of the European Society of Hypertension (ESH) and the European Society of Cardiology (ESC) 2013 for the treatment of hypertension. Particular attention is given to the group of angiotensin receptor blockers and irbesartan.
