Symptoms: dizziness, nausea, and vomiting. With intravenous administration of ranolazine following symptoms were further noted: diplopia, confusion, fainting. Severity of symptoms can be enhanced by increasing the dose. Treatment: . Symptomatic primobolan cycle under careful medical supervision for 30 minutes after taking the drug can take measures to prevent its absorption from the gastrointestinal tract (gastric lavage, administration of activated charcoal). Hemodialysis is ineffective.
Interaction with other drugs
Ranolazine is a substrate of cytochrome. The simultaneous use of ranolazine isoenzyme inhibitors increases the concentration in plasma ranolazine. Probability of development of dose-related side effects (eg, nausea, dizziness) may also increase with an increase in ranolazine plasma concentrations.
Concomitant use contraindicated: Strong inhibitors Concomitant use of ranolazine and strong inhibitors (eg, itraconazole, ketoconazole, voriconazole, posaconazole, HIV protease inhibitors, clarithromycin, telithromycin, nefazodone) is contraindicated (see section. “Contraindications” ). Simultaneous treatment with ketoconazole 200 mg 2 times a day increases the of ranolazine by 3.0 – 3.9 times. Grapefruit juice is also a potent inhibitor isoenzyme.
Concomitant use with caution: Moderate inhibitors Inducers of CYP3A4 should not start taking ranolazine to patients receiving treatment with inducers of (rifampicin, phenytoin, phenobarbital, carbamazepine, St. John’s wort (Hypericum perforatum)). Since, for example, rifampicin (600 mg once daily) reduces the equilibrium concentration in the blood plasma ranolazine of about 95%. Inhibitors isozyme Ranolazine partially metabolized isoenzyme. The simultaneous use of ranolazine isozyme inhibitors may increase the ranolazine plasma concentrations. The simultaneous use of ranolazine 1000 mg 2 times a day with a potent inhibitorisozyme paroxetine 20 mg 1 time per day increases the average concentration of ranolazine plasma at steady state is about 1.2 times. No dose adjustment is required. The simultaneous use of ranolazine 500 mg 2 times a day, a potent inhibitor of CYP2D6 isozyme may lead to an increase in AUC of ranolazine of about 62%.The inhibitors / substrates of P-gp (P-glycoprotein) Ranolazine is a substrate of P-gp. Inhibitors of P-gp (such as cyclosporine, verapamil) increase the concentration of ranolazine plasma. Verapamil (120 mg tid) increases the equilibrium concentration of ranolazine 2.2 times. For patients treated with inhibitors of P-gp, ranolazine recommended dose titration. You may need to decrease the dose of ranolazine. On the other hand, ranolazine is a moderate inhibitor of P-gp and may increase the concentration of P-gp substrates in plasma. Tissue distribution of drugs which are transported by P-gp, may be increased.Substrates isozyme There is evidence that ranolazine is a weak inhibitor isozyme. Receiving ranolazine 750 mg 2 times a day increases in the plasma concentration of metoprolol in 1.8 times. Therefore, while the use of ranolazine, may potentiate metoprolol or other substrates isoenzyme primobolan cycle (e.g., propafenone and flecainide, to a lesser extent, tricyclic antidepressants and neuroleptics) thereby may require dose reduction of these drugs. Substrates isoenzyme potential to inhibit isoenzyme is not installed. During the appointment, together with the isoenzyme substrates (eg bupropion, efavirenz, cyclophosphamide) recommend caution. Digoxin There is evidence of increasing the concentration of digoxin in the blood plasma of on average 1.5 times, while the use of digoxin and ranolazine. Therefore, a control digoxin concentrations at the beginning and after the end of therapy with ranolazine. Substrates isoenzyme is a weak inhibitor of isozyme which may lead to increased concentrations isoenzyme substrates in plasma and require dose correction sensitive substrates isoenzyme for example, simvastatin, lovastatin) and substrates with narrow therapeutic range (eg, cyclosporine, tacrolimus, sirolimus, everolimus). simvastatin metabolism and clearance of simvastatin are highly dependent on isoenzyme. Receiving ranolazine 1000 mg two times a day increases the concentration of the simvastatin lactone and simvastatinovoy acid in blood plasma at about 2 times. Simvastatin in high doses associated with the development of rhabdomyolysis, also cases of rhabdomyolysis while the use of ranolazine and simvastatin have been described. The maximum dose of simvastatin for patients receiving simultaneously primobolan cycleranolazine, should not exceed 20 mg / day. buy anabolic steroids online bruce lee’s workout anabolic steroids online uk
