Interaction entre Lopinavir et ritonavir et Morphine

…Hepatitis C direct acting antiviral: elbasvir/grazoprevir HMG-CoA Reductase Inhibitors: lovastatin, simvastatin Microsomal triglyceride transfer protein (MTTP) Inhibitor: lomitapide Non-opioid Analgesic (selective blocker of Nav1.8 sodium channels): suzetrigine PDE5 Inhibitor: sildenafil (Revatio ® ) when used for the treatment of pulmonary arterial hypertension Sedative/Hypnotics:…

Postmarketing life-threatening cases of cardiac toxicity (including complete AV block, bradycardia, and cardiomyopathy), lactic acidosis, acute renal failure, CNS depression and respiratory complications leading to death have been reported, predominantly in preterm neonates receiving KALETRA oral solution.

Sedative/Hypnotics: triazolam, orally administered midazolam ↑ triazolam ↑ midazolam Contraindicated due to potential for prolonged or increased sedation or respiratory depression [see Contraindications ( 4 )] .

…potential risks, infants should be monitored closely for increases in serum osmolality and serum creatinine, and for toxicity related to KALETRA oral solution including: hyperosmolality, with or without lactic acidosis, renal toxicity, CNS depression (including stupor, coma, and apnea), seizures, hypotonia, cardiac arrhythmias and ECG changes, and hemolysis.

Analgesics Opioid: methadone* fentanyl Non-opioid analgesic (selective blocker of Na v 1.8 sodium channels): suzetrigine ↓ methadone ↑ fentanyl ↑ suzetrigine and active metabolite M6-SUZ Dosage of methadone may need to be increased when co-administered with KALETRA.

P-Glycoprotein (P-gp) Inhibitors Clinical Impact: The concomitant use of P-gp inhibitors can increase the exposure to morphine by two-fold and can increase the risk of hypotension, respiratory depression, profound sedation, coma, and death.

Intervention: Evaluate patients for signs of respiratory depression that may be greater than otherwise expected and decrease the dosage of Morphine Sulfate Oral Solution and/or the P-gp inhibitor as necessary.
