The decrease in AUC, Cmax, and Cmin was not mitigated when an increased dose of REYATAZ/ritonavir (400/100 mg once daily) was temporally separated from omeprazole by 12 hours. Although not studied, similar results are expected with other proton pump inhibitors. This decrease in atazanavir exposure might negatively impact the efficacy of atazanavir. The mechanism of interaction is decreased solubility of atazanavir as intra-gastric pH increases with proton pump inhibitors.

Atazanavir is metabolised in the liver through CYP3A4. It inhibits CYP3A4. Therefore, REYATAZ with ritonavir is contraindicated with medicinal products that are substrates of CYP3A4 and have a narrow therapeutic index: quetiapine, lurasidone, alfuzosin, astemizole, terfenadine, cisapride, pimozide, quinidine, bepridil, triazolam, orally administered midazolam, lomitapide, and ergot alkaloids, particularly ergotamine and dihydroergotamine (see section 4.3). Co-administration of REYATAZ with grazoprevir-containing products, including elbasvir/grazoprevir fixed-dose combination is contraindicated because of the increase in grazoprevir and elbasvir plasma concentrations and potential for the increase in risk of ALT elevations associated with increased grazoprevir concentrations (see section 4.3). Co-administration of REYATAZ with glecaprevir/pibrentasvir fixed-dose combination is contraindicated because of the potential increase in the risk of ALT elevations due to a significant increase in glecapreir and pibrentasvir plasma concentrations (see section 4.3).

These active substances include antiarrhythmics (such as amiodarone, bepridil, quinidine), antihistamines (such as astemizole, terfenadine), ergot derivatives (such as dihydroergotamine, ergonovine, ergotamine, methylergonovine), gastrointestinal motility agents (such as cisapride), antipsychotics (such as pimozide, sertindole, quetiapine, lurasidone), sedatives/hypnotics (such as orally administered midazolam and triazolam) and HMG-CoA reductase inhibitors (such as simvastatin and lovastatin) (see section 4.5). Also the use of the alpha-1 adrenoceptor antagonist alfuzosin, and sildenafil when used for the treatment of pulmonary arterial hypertension. In addition, co-administration of Aptivus with low dose ritonavir, and medicinal products that are highly dependent on CYP2D6 for clearance, such as the antiarrhythmics flecainide, propafenone and metoprolol given in heart failure (see section 4.5).

Darunavir boosted with either ritonavir or cobicistat inhibits the elimination of active substances that are highly dependent on CYP3A for clearance, which results in increased exposure to the co-administered medicinal product. Therefore, concomitant treatment with such medicinal products for which elevated plasma concentrations are associated with serious and/or life-threatening events is contraindicated (applies to darunavir boosted with either ritonavir or cobicistat). These active substances include e.g.: - alfuzosin - amiodarone, bepridil, dronedarone, ivabradine, quinidine, ranolazine - astemizole, terfenadine - colchicine when used in patients with renal and/or hepatic impairment (see section 4.5) - ergot derivatives (e.g. dihydroergotamine, ergometrine, ergotamine, methylergonovine) - elbasvir/grazoprevir - cisapride - dapoxetine - domperidone - naloxegol - lurasidone, pimozide, quetiapine, sertindole (see section 4.5) - triazolam, midazolam administered orally (for caution on parenterally administered midazolam, see section 4.5) - sildenafil - when used for the treatment of pulmonary arterial hypertension, avanafil - simvastatin, lovastatin, lomitapide (see section 4.5) - ticagrelor (see section 4.5).
