Isolated cases of hepatitis, toxic epidermal necrolysis, Stevens-Johnson syndrome, erythema multiforme and bradyarrhythmia have also been reported with lopinavir/ritonavir.

Interaction

Lopinavir / ritonavir is an in vitro and in vivo inhibitor of the CYP3A isoenzyme. Concomitant use of lopinavir / ritonavir and drugs primarily metabolized by the CYP3A isoenzyme (for example, dihydropyridine slow calcium channel blockers, HMG-CoA reductase inhibitors, immunosuppressants, and phosphodiesterase 5 (PDE-5) inhibitors) may lead to an increase in plasma concentrations of these drugs, the therapeutic or side effects of which may increase or last. In drugs that are actively metabolized by the CYP3A isoenzyme and have a high presystemic metabolism, when taken simultaneously with lopinavir/ritonavir, a significant increase in AUC (more than 3-fold) is more often observed. Drugs that are contraindicated precisely because of undesirable interactions and the possibility of developing serious side effects are listed in the section “Contraindications”.

Lopinavir / ritonavir is metabolized by the CYP3A isoenzyme. Concomitant use of lopinavir/ritonavir and drugs that induce the CYP3A isoenzyme may reduce plasma concentrations of lopinavir and reduce its therapeutic effect, although these changes were not observed when co-administered with ketoconazole.

Concomitant use of lopinavir / ritonavir and other drugs that inhibit the CYP3A isoenzyme may increase plasma concentrations of lopinavir.

Drugs used to treat HIV

Nucleoside reverse transcriptase inhibitors (NRTIs)

Stavudine and lamivudine

There were no changes in the pharmacokinetics of lopinavir when lopinavir/ritonavir was co-administered with stavudine and lamivudine compared to lopinavir/ritonavir monotherapy.

Didanosine

It is recommended to take didanosine on an empty stomach; therefore, in combination with didanosine, lopinavir/ritonavir tablets should be taken one hour before or two hours after a meal.

Zidovudine and abacavir

Lopinavir / ritonavir induces glucuronidation, so the drug can reduce the plasma concentrations of zidovudine and abacavir. The clinical significance of this potential interaction is unknown.

Tenofovir

The study showed that lopinavir / ritonavir increases the concentration of tenofovir in blood plasma. The mechanism of this interaction is unknown. Patients taking lopinavir / ritonavir and tenofovir should be monitored for tenofovir-related side effects.

Other NRTs

Increased creatine phosphokinase (CPK) activity, myalgia, myositis and, rarely, rhabdomyolysis have been reported with HIV protease inhibitors, especially in combination with NRTIs.

Non-nucleoside reverse transcriptase inhibitors(NNRTIs)

Nevirapine

There were no changes in the pharmacokinetics of lopinavir in healthy adult patients during concomitant use of nevirapine and lopinavir/ritonavir. The results of a study involving HIV-positive children showed a decrease in lopinavir concentrations during concomitant use with nevirapine. It is believed that the effect of nevirapine on HIV-positive adult patients may be similar to that in children, which may lead to a decrease in the concentration of lopinavir. The clinical significance of the pharmacokinetic interaction is unknown.

In patients who have previously received antiretroviral therapy or who have phenotypic or genotypic signs of a significant decrease in sensitivity to lopinavir, when lopinavir / ritonavir is co-administered with nevirapine, it may be necessary to increase the dose of lopinavir / ritonavir to 500/125 mg twice daily. Lopinavir / ritonavir in combination with nevirapine should not be used once a day.

Efavirenz

Increasing the dose of lopinavir/ritonavir tablets to 500/125 mg (two Kaletra tablets 200/50 mg + one Kaletra tablet 100/25 mg) twice a day does not affect the concentration of lopinavir in blood plasma in comparison with the use of lopinavir/ritonavir 400/100 mg twice a day without efavirenz. Increasing the dose of lopinavir/ritonavir tablets to 600/150 mg (three (3) 200/50 mg tablets) twice daily when co-administered with efavirenz increased the plasma concentration of lopinavir by approximately 36% and the concentration of ritonavir by approximately 56%-92% compared to the dose of lopinavir/ritonavir 400/100 mg (two (2) 200/50 mg tablets) when taken twice daily without efavirenz (see section “Dosage and use”).

Efavirenz and nevirapine induce the CYP3A isoenzyme and, thus, can reduce the plasma concentrations of other viral protease inhibitors when used in combination with lopinavir/ritonavir. Concomitant use of lopinavir / ritonavir with both efavirenz and nevirapine once daily is contraindicated.

Delavirdin

Delavirdine is able to increase the concentration of lopinavir in plasma.

HIV protease inhibitors

Amprenavir

Lopinavir / ritonavir may increase amprenavir concentrations (taking amprenavir at a dose of 750 mg twice daily plus lopinavir / ritonavir leads to an increase in AUC similar to_cmax, an increase in_Cmin relative to amprenavir at a dose of 1200 mg twice daily). Concomitant use of lopinavir / ritonavir and amprenavir reduces the concentration of lopinavir (see section “Dosage and use”). Concomitant use of lopinavir / ritonavir with amprenavir once daily is contraindicated.

Fosamprenavir

The study showed that concomitant use of lopinavir / ritonavir with fosamprenavir reduces the concentrations of fosamprenavir and lopinavir. Adequate safety and efficacy doses of fosamprenavir and lopinavir/ritonavir in combination have not been established.

Indinavir

Lopinavir/ritonavir may increase the concentration of indinavir (when combined with indinavir at a dose of 600 mg twice a day with simultaneous use of lopinavir/ritonavir, a decrease in_cmax, an increase in_cmin compared to taking indinavir three times a day at a dose of 800 mg is observed, while AUC is similar). The indinavir dose may need to be reduced when lopinavir/ritonavir is co-administered 400/100 mg twice daily. use of lopinavir / ritonavir in combination with indinavir once daily has not been studied.

Nelfinavir

Lopinavir / ritonavir may increase the concentrations of nelfinavir and the nelfinavir metabolite M8 (when taking nelfinavir 1000 mg twice daily and lopinavir/ritonavir compared to taking nelfinavir 1250 mg twice daily, similar AUC, similar_cmax, increased_{cmin are observed}). Concomitant use of lopinavir / ritonavir and nelfinavir leads to a decrease in lopinavir concentrations (see section “Dosage and use”). Concomitant use of lopinavir / ritonavir with nelfinavir once daily is contraindicated.

Ritonavir

When lopinavir/ritonavir was co-administered with an additional 100 mg of ritonavir twice daily, the AUC of lopinavir increased by 33% and Cmin increased by 64% compared to lopinavir/ritonavir 400/100 mg twice daily.

Saquinavir

Lopinavir / ritonavir increases saquinavir concentrations (saquinavir 800 mg twice daily plus lopinavir / ritonavir compared to saquinavir 1200 mg three times daily leads to an increase in AUC, _cmax and_cmin). The dose of saquinavir co-administered with lopinavir/ritonavir 400/100 mg twice daily may need to be reduced. use of lopinavir / ritonavir in combination with saquinavir once daily has not been studied.

Tipranavir

When tipranavir (500 mg twice daily) is co-administered with ritonavir (200 mg twice daily) and lopinavir/ritonavir (400/100 mg twice daily), the AUC and_cmin of lopinavir decrease by 55% and 70%, respectively. Concomitant use of lopinavir / ritonavir and tipranavir with a low dose of ritonavir is contraindicated.

Hepatitis C virus protease inhibitors

Telaprevir

Concomitant use of lopinavir / ritonavir with telaprevir leads to a decrease in the steady-state concentration of telaprevir without changing the steady-state concentration of lopinavir.

Boceprevir

Concomitant use of lopinavir / ritonavir with boceprevir leads to a decrease in the steady-state concentrations of boceprevir and lopinavir. Concomitant use of lopinavir / ritonavir with boceprevir is contraindicated.

Antiviral drugs — inhibitors of the CCR5 chemokine receptor

Maravirok

Simultaneous use of maraviroc with lopinavir / ritonavir leads to an increase in the concentration of maraviroc. When used concomitantly with lopinavir/ritonavir at a dose of 400/100 mg twice daily, the dose of maraviroc should be reduced. The dosage of maraviroc should be selected in accordance with its instructions for use.

Other medications

Narcotic analgesics

Fentanyl

Since lopinavir / ritonavir inhibits the CYP3A4 isoenzyme, it is possible to increase the concentration of fentanyl in blood plasma.

Therapeutic and side effects (including respiratory depression) should be carefully monitored when lopinavir/ritonavir and fentanyl are co-administered.

Antiarrhythmic drugs (bepridil, lidocaine and quinidine)

Concomitant use with lopinavir / ritonavir may increase the concentrations of these drugs. Caution should be exercised when using these drugs and monitoring therapeutic concentrations, if possible.

Digoxin

An analysis of the literature showed that concomitant use of ritonavir (300 mg every 12 hours) and digoxin resulted in a significant increase in the concentration of digoxin in the blood. Caution should be exercised when using lopinavir/ritonavir concomitantly with digoxin, while monitoring serum digoxin concentrations.

Medications that extend the QT interval

Under the influence of lopinavir / ritonavir, concentrations of phenyramine, quinidine, erythromycin, clarithromycin may increase, followed by prolongation of the QT interval and the development of cardiac side effects. Special care should be taken when using lopinavir/ritonavir concomitantly with drugs that prolong the QT interval.

Anticancer agents (e. g. dasatinib, nilotinib, vincristine, vinblastine)

It is possible to increase their serum concentrations when used simultaneously with lopinavir/ritonavir, which can lead to side effects usually associated with these antitumor drugs.

The dosage of nilotinib and dasatinib should be selected in accordance with the instructions for use of these drugs.

Anticoagulants

Possible effect on warfarin concentrations when used concomitantly with lopinavir / ritonavir. It is recommended to monitor the INR (International Normalized ratio).

Rivaroxaban

Concomitant use of rivaroxaban with lopinavir / ritonavir may increase the concentration of rivaroxaban, which may lead to an increased risk of bleeding.

Antidepressants

Bupropion

Concomitant use of bupropion with lopinavir/ritonavir reduces plasma concentrations of bupropion and its active metabolite (hydroxybupropion). If concomitant use of lopinavir/ritonavir with bupropion is necessary, then it should be carried out under close clinical monitoring of the effectiveness of bupropion without exceeding the recommended dose, despite the observed increase in metabolism.

Trazodone

Concomitant use of ritonavir and trazodone may increase the concentration of trazodone. Side effects were observed: nausea, dizziness, hypotension and fainting. Use trazodone with a CYP3A4 inhibitor, such as lopinavir/ritonavir, should be used with caution and reduce the dose of trazodone.

Anticonvulsants (phenobarbital, phenytoin, carbamazepine)

It is known that these drugs can induce the CYP3A4 isoenzyme and, thus, reduce the concentration of lopinavir. Concomitant use of lopinavir / ritonavir once daily in combination with phenobarbital, phenytoin or carbamazepine is contraindicated.

In addition, the concomitant use of phenytoin and lopinavir / ritonavir leads to a moderate decrease in steady-state concentrations of phenytoin. Phenytoin concentrations should be monitored when the drug is administered concomitantly with lopinavir / ritonavir.

Lamotrigine and valproic acid

Concomitant use of these drugs with lopinavir/ritonavir resulted in a decrease in lamotrigine and valproic acid concentrations. The decrease in lamotrigine concentration reached 50%. These drug combinations should be used with caution. When these drugs are co-administered with lopinavir/ritonavir, especially during the dose selection period, it may be necessary to increase the dose of lamotrigine or valproic acid, as well as monitor their concentration in blood plasma.

Antifungal products

Serum concentrations of ketoconazole and itraconazole may increase under the influence of lopinavir/ritonavir. The use of ketoconazole and itraconazole in high doses (more than 200 mg / day) together with lopinavir / ritonavir is not recommended.

Voriconazole

The study showed that concomitant use of ritonavir at a dose of 100 mg every 12 hours reduces the steady-state AUC of voriconazole by an average of 39%; concomitant use of lopinavir/ritonavir and voriconazole is contraindicated.

Medications for the treatment of gout

Concomitant use of colchicine with lopinavir / ritonavir may increase the concentration of colchicine. use and dose selection of colchicine should be carried out in accordance with its instructions for use.

Antibacterial agents

Lopinavir/ritonavir may cause a moderate increase in clarithromycin AUC. In patients with impaired renal or hepatic function, the dose of clarithromycin should be reduced when used concomitantly with lopinavir / ritonavir.

Anti-tuberculosis drugs

Rifabutin

When rifabutin and lopinavir/ritonavir were co-administered for ten days, the_cmax and AUC of rifabutin (unchanged drug and active 25-O-deacetyl metabolite) increased 3.5-fold and 5.7-fold, respectively. Based on these data, it is recommended to reduce the dose of rifabutin by 75% (i. e. 150 mg every other day or three times a week) when used with lopinavir/ritonavir. Further dose reduction of rifabutin may be necessary.

Rifampicin

Concomitant use of rifampicin with lopinavir / ritonavir is accompanied by a dose-dependent decrease in the plasma concentration of lopinavir compared to the use of lopinavir/ritonavir at a standard dose of 400/100 mg without rifampicin. The use of rifampicin with a standard dose of lopinavir / ritonavir may lead to a loss of virological response and possible development of resistance to lopinavir/ritonavir or to a class of HIV protease inhibitors or other antiretroviral drugs used simultaneously.

When rifampicin is co-administered with lopinavir / ritonavir (800/200 mg twice daily) the decrease in plasma concentrations of lopinavir reached 57% compared to the use of lopinavir/ritonavir at a dose of 400/100 mg twice a day without simultaneous use of rifampicin. When rifampicin was co-administered with lopinavir / ritonavir at a dose of 400/400 mg twice daily, the corresponding decrease in the concentration of lopinavir in blood plasma reached 7%.

In studies with higher doses of lopinavir/ritonavir when used concomitantly with rifampicin, an increase in ALT and AST activity was observed, this phenomenon may depend on the sequence of dose use.

If the concomitant use of lopinavir/ritonavir and rifampicin is necessary, lopinavir/ritonavir should be started at a standard dose of 400/100 mg twice daily approximately 10 days before the start of rifampicin, and the dose of lopinavir/ritonavir should be gradually increased. Careful monitoring of liver function is necessary.

Antiparasitic agents

It is possible to reduce the therapeutic concentration of atovahone when used simultaneously with lopinavir / ritonavir. It may be necessary to increase the doses of atovahone.

Glucocorticosteroids (corticosteroids)

Dexamethasone may cause an increase in CYP3A4 activity and a decrease in lopinavir concentrations.

Fluticasone: concomitant use of lopinavir / ritonavir and fluticasone may significantly increase plasma concentrations of fluticasone and lower serum cortisol concentrations. Use with caution. It is recommended to consider alternatives to fluticasone, especially for long-term use.

Systemic effects of glucocorticosteroids, including Itsenko-Cushing syndrome and adrenal suppression, have been reported when ritonavir is co-administered with intranasal and inhaled forms of fluticasone and budesonide.

Concomitant use of lopinavir/ritonavir and fluticasone, as well as other CORTICOSTEROIDS that are metabolized by CYP3A4, such as budesonide, is not recommended, unless the potential benefit of such therapy outweighs the risk of systemic corticosteroid effects, including Cushing’s syndrome and adrenal suppression.

Special caution should be exercised when lopinavir/ritonavir is co-administered with any of the inhaled or nasal glucocorticosteroids.

Consideration should be given to reducing the dose of glucocorticosteroid with careful monitoring of local and general reactions, or switching to a glucocorticosteroid that is not a substrate for CYP3A4 (e. g. Beclomethasone). Also, in case of discontinuation of glucocorticoid therapy, a gradual dose reduction should be carried out over a long period.

Slow calcium channel blockers (for example, felodipine, nifedipine, nicardipine).

There may be an increase in serum concentrations of these drugs when used concomitantly with lopinavir/ritonavir.

PDE5 inhibitors

Special care should be taken when using sildenafil and tadalafil for the treatment of erectile dysfunction in patients taking lopinavir/ritonavir, since when taking these drugs simultaneously, you can expect a significant increase in their concentrations and the development of side effects such as hypotension and prolonged erection.

Sildenafil

Use of sildenafil for the treatment of erectile dysfunction should be carefully reduced in doses (25 mg every 48 hours) and more often monitor side effects.

The use of sildenafil for the treatment of pulmonary arterial hypertension while taking lopinavir/ritonavir is contraindicated.

Tadalafil

Tadalafil should be used cautiously in reduced doses (no more than 10 mg every 72 hours) and side effects should be monitored more often.

The use of tadalafil for the treatment of pulmonary arterial hypertension while taking lopinavir/ritonavir is not recommended.

Vardenafil

Concomitant use of vardenafil with lopinavir / ritonavir is contraindicated.

Medicinal products of plant origin

Concomitant use of drugs containing St. John’s wort is contraindicated in patients receiving treatment with lopinavir/ritonavir, as this combination may reduce the concentrations of lopinavir/ritonavir in plasma. This effect may occur due to the induction of the CYP3A4 isoenzyme and may lead to a loss of therapeutic effect and the development of resistance.

HMG-CoA reductase inhibitors

Lopinavir/ritonavir may cause a significant increase in plasma concentrations of HMG-CoA reductase inhibitors metabolized by CYP3A4, such as lovastatin and simvastatin. Increased concentrations of these statins can lead to the development of myopathy, including rhabdomyolysis, so their combination with lopinavir / ritonavir is contraindicated. Rosuvastatin and atorvastatin, whose metabolism is less dependent on the CYP3A4 enzyme, should be used together with ritonavir/lopinavir with caution in minimal doses. When taken in combination with lopinavir / ritonavir, an increase in_cmax and AUC of atorvastatin by 4.7 and 5.9 times, respectively, was observed, which increases the risk of serious adverse reactions of myopathy and rhabdomyolysis.

No clinically significant interaction of lopinavir / ritonavir with pravastatin was detected. The metabolism of pravastatin and fluvastatin is independent of CYP3A4, so they should not interact with lopinavir/ritonavir. If treatment with HMG-CoA reductase inhibitors is indicated during the use of lopinavir/ritonavir, it is recommended to use pravastatin or fluvastatin.

Immunosuppressants

Concentrations of these drugs (e. g. cyclosporine, tacrolimus, and sirolimus) may increase when used concomitantly with lopinavir / ritonavir. More frequent monitoring of therapeutic concentrations is recommended until the concentrations of these drugs in the blood are stabilized.

Methadone

Lopinavir/ritonavir has been shown to reduce plasma concentrations of methadone. Monitoring of methadone plasma concentrations is recommended.

Buprenorphine

Buprenorphine at a dose of 16 mg once a day does not require a dose change.

Oral contraceptives or contraceptives in the form of a patch

Since ethinyl estradiol concentrations may be reduced by concomitant use of lopinavir / ritonavir and estrogen-containing oral contraceptives or patch-based contraceptives, alternative or complementary contraceptive measures should be used.

Vasodilators

Concomitant use of bosentan in combination with lopinavir/ritonavir_{resulted in a 6-and 5-fold increase in bosentan cmax} and AUC, respectively. Bosentan should be prescribed and selected in accordance with its instructions for use.

No clinically significant interaction is expected

No clinically significant interactions of lopinavir / ritonavir with desipramine, raltegravir, omeprazole, or ranitidine have been reported.Based on the data on metabolism, no clinically significant interaction of lopinavir/ritonavir with fluvastatin, dapsone, trimethoprim sulfamethoxazole, azithromycin or fluconazole is expected in patients with normal renal and hepatic function.

How to take, course of use and dosage

The recommended dose for adults and adolescents is 400/100 mg (5 ml of oral solution) 2 times / day with meals. The oral solution can be used in patients who have difficulty swallowing.

Oral solution for children over 2 years of age is prescribed at a dose of 230/57.5 mg / m2 2 times/day with meals; the maximum dose is 400/100 mg 2 times/day. The dose of 230/57.5 mg / m2 may not be sufficient in some children who are taking nevirapine or efavirenz at the same time. In this case, it is necessary to increase the dose to 300/75 mg / m2. Dosing should be carried out using a dosing syringe.

Overdose

Currently, the clinical experience of acute overdose with lopinavir/ritonavir in humans is limited. There is no specific antidote.

Treatment consists of activities aimed at maintaining the body’s life support, including monitoring vital systems and monitoring the patient’s clinical condition.

If necessary, remove unabsorbed drugs by gastric lavage, for which the appointment of activated carbon may be useful. Since lopinavir/ritonavir is highly bound to plasma proteins, the use of dialysis is impractical.

Special instructions

Impaired liver function

Lopinavir/ritonavir is mainly metabolized in the liver. In this regard, caution should be exercised when prescribing this drug to patients with mild to moderate hepatic impairment. The use of lopinavir/ritonavir has not been studied in patients with severe hepatic impairment. Pharmacokinetic data indicate that in HIV-positive patients with HCV infection and mild to moderate hepatic impairment, lopinavir may increase plasma concentrations by approximately 30%, as well as reduce its binding to plasma proteins. If you have hepatitis B or C or a significant increase in the activity of aminotransferases before starting treatment, the risk of further increase is increased. In clinical practice, cases of impaired liver function, including those with a fatal outcome, have been reported. They were usually observed in patients with advanced HIV infection and concomitant chronic hepatitis or cirrhosis of the liver, who received excessive drug therapy. The association of these cases with lopinavir/ritonavir therapy has not been established.

Cases of increased transaminase activity have been reported with or without a concomitant increase in bilirubin concentrations within seven days of starting lopinavir / ritonavir in combination with other antiviral agents. In some cases, liver function disorders were severe, but a causal relationship between these cases and lopinavir/ritonavir therapy has not been established.

In such situations, it is advisable to monitor the activity of AST/ALT more often, especially in the first months after the appointment of lopinavir/ritonavir.

Diabetes mellitus/hyperglycemia

In the course of post-marketing surveillance, cases of development and decompensation of diabetes mellitus and hyperglycemia were reported in HIV-infected patients treated with protease inhibitors. In some cases, it was necessary to prescribe insulin or oral hypoglycemic agents or increase their doses. Sometimes diabetic ketoacidosis developed. In some patients, hyperglycemia persisted after discontinuation of the protease inhibitor. These cases were reported on a voluntary basis, so it was not possible to assess their frequency and association with protease inhibitor therapy.

Pancreatitis

Patients treated with lopinavir/ritonavir were observed to develop pancreatitis, including against the background of severe hypertriglyceridemia. Fatal cases have been reported. Although the association of this side effect with lopinavir/ritonavir has not been established, however, a significant increase in triglyceride concentrations is a risk factor for pancreatitis. Patients with advanced HIV infection have an increased risk of developing hypertriglyceridemia and pancreatitis, and patients with a history of pancreatitis have an increased risk of its exacerbation during treatment with lopinavir/ritonavir.

Resistance/cross-resistance

When studying protease inhibitors, cross-resistance of varying severity was observed. The effect of lopinavir/ritonavir on the effectiveness of subsequent therapy with other protease inhibitors is currently being studied.

Hemophilia

Cases of bleeding, including spontaneous subcutaneous hematoma formation and development of hemarthrosis, have been reported in patients with type A and B hemophilia treated with protease inhibitors. Some patients were given additional doses of factor VIII. In more than half of the cases described, treatment with protease inhibitors was continued or resumed. The causal relationship or mechanism of development of such adverse events during treatment with protease inhibitors has not been established.

Lengthening the PR interval

When taking lopinavir/ritonavir, some patients showed a moderate asymptomatic prolongation of the PR interval. When taking lopinavir/ritonavir, rare cases of grade II and III atrioventricular block have been reported in patients with organic heart disease and pre-existing disorders of the cardiac conduction system or in patients taking drugs that extend the PR interval (such as verapamil or atazanavir). Lopinavir / ritonavir should be used with caution in these patients.

Electrocardiogram

The QTcF interval (adjusted for Fridericia) was evaluated in a randomized, placebo-controlled cross – sectional study with active control (moxifloxacin 400 mg once daily) in 39 healthy adult volunteers. 10 measurements were performed for 12 hours on day 3 of the study. The mean maximum difference in QTcF compared to placebo was 3.6 (6.3) ms and 13.1 (15.8) ms for doses of 400/100 mg twice daily and 800/200 mg twice daily of lopinavir/ritonavir, respectively. The changes observed when using the above two dosage regimens were approximately 1.5 and 3 times higher than those observed when taking the recommended doses of lopinavir/ritonavir once a day or twice a day at steady state. None of the patients showed an increase in the QTcF interval >60 ms compared to the baseline value; the QTcF interval did not exceed the potentially clinically significant threshold of 500 ms. >

In the same study, a moderate increase in the PR interval was also observed in patients taking lopinavir/ritonavir on day 3. The maximum PR interval was 286 ms, and there was no development of grade II or III atrioventricular block.

Fat redistribution

On the background of antiretroviral therapy, fat redistribution/accumulation was observed with its deposition in the central parts of the body, in the back and neck, the appearance of a “buffalo hump”, a decrease in fat deposits on the face and limbs, an increase in mammary glands and kushingoid. The mechanism and long-term consequences of these adverse events are not known. Their connection with therapy has not been established.

Increased lipid concentrations

Lopinavir/ritonavir treatment resulted in increased total cholesterol and triglyceride concentrations. Before starting treatment with lopinavir/ritonavir and regularly during therapy, triglyceride and cholesterol concentrations should be monitored. In the presence of lipid disorders, appropriate therapy is indicated.

Immune recovery syndrome

Patients who received combined antiretroviral therapy, including lopinavir/ritonavir, developed a syndrome of restoring immunity. When immune function is restored at the beginning of combined antiretroviral therapy, asymptomatic or residual opportunistic infections (such as Mycobacterium avium, cytomegalovirus, Pneumocystis jiroveci (Pneumocystis carinii) or Mycobacterium tuberculosis) may worsen, which may require additional examination and treatment.

Autoimmune diseases, such as Graves ‘ disease, polymyositis, and Guillain-Barre syndrome, have been observed with the development of immune recovery syndrome, but the duration of occurrence of these phenomena can vary significantly and can be several months from the start of therapy.

Osteonecrosis

It is known that many factors play a role in the etiology of osteonecrosis (taking corticosteroids, alcohol abuse, high body mass index, severe immunosuppression, etc. ). In particular, cases of osteonecrosis have been reported in patients with advanced HIV infection and / or long-term use of combined antiretroviral therapy. Therefore, these patients should be advised to consult a doctor if they experience pain, stiffness in the joints and impaired motor function.

Use in the elderly

The number of patients aged 65 years and older was insufficient to assess the possible differences in their response to lopinavir/ritonavir treatment compared to those in younger patients. Caution should be exercised when using lopinavir/ritonavir in the elderly, given the increased incidence of decreased liver, kidney or heart function, comorbidities, and concomitant therapy.

Use in children

The safety and pharmacokinetics of lopinavir/ritonavir in children less than 6 months of age have not been established. In HIV-infected children aged 6 months to 12 years, the side effect profile in the clinical study was similar to that in adults.

The use of lopinavir/ritonavir once daily has not been studied in children.

Influence on the ability to drive motor vehicles, manage mechanisms

During the treatment period, care should be taken when driving vehicles and engaging in other potentially dangerous activities that require increased concentration of attention and speed of psychomotor reactions. If you develop side effects that may affect these abilities, such as dizziness, it is recommended to refrain from driving vehicles and operating mechanisms. Studies of the ability to drive motor vehicles and manage mechanisms have not been conducted.
