Review the full interaction monograph for more information.
| Drug Interaction | Drug Names |
|---|---|
| Selected P-glycoprotein (P-gp) Substrates/Capmatinib SEVERITY LEVEL: 2-Severe Interaction: Action is required to reduce the risk of severe adverse interaction. MECHANISM OF ACTION: Capmatinib is an inhibitor of the P-glycoprotein (P-gp) system. P-gp substrates with a narrow therapeutic index may be increased.(1) CLINICAL EFFECTS: Concurrent use of capmatinib with narrow therapeutic index P-gp substrates may result in elevated levels of the substrate, increasing the risk for adverse effects.(1) PREDISPOSING FACTORS: None determined. PATIENT MANAGEMENT: The US manufacturer of capmatinib states that the concurrent use of narrow therapeutic index P-gp substrates should be avoided. If concurrent therapy cannot be avoided, the dosage of the narrow therapeutic index P-gp substrate should be decreased according to the substrate prescribing information.(1) DISCUSSION: In a study, capmatinib increased digoxin's area-under-curve (AUC) by 47% and maximum concentration (Cmax) by 74%.(1) Selected narrow therapeutic index P-gp substrates include: afatinib, betrixaban, digoxin, etoposide, everolimus, loperamide, sirolimus, and ubrogepant.(1,2) |
TABRECTA |
| Selected P-glycoprotein (P-gp) Substrates/Sotorasib SEVERITY LEVEL: 2-Severe Interaction: Action is required to reduce the risk of severe adverse interaction. MECHANISM OF ACTION: Sotorasib is an inhibitor of the P-glycoprotein (P-gp) system. P-gp substrates with a narrow therapeutic index may be increased.(1) CLINICAL EFFECTS: Concurrent use of sotorasib with narrow therapeutic index P-gp substrates may result in elevated levels of the substrate, increasing the risk for adverse effects.(1) PREDISPOSING FACTORS: None determined. PATIENT MANAGEMENT: The US manufacturer of sotorasib states that the concurrent use of narrow therapeutic index P-gp substrates should be avoided. If concurrent therapy cannot be avoided, the dosage of the narrow therapeutic index P-gp substrate should be decreased according to the substrate prescribing information.(1) DISCUSSION: In a study, sotorasib increased digoxin's area-under-curve (AUC) by 21% and maximum concentration (Cmax) by 91%.(1) Selected narrow therapeutic index P-gp substrates include: afatinib, betrixaban, digoxin, edoxaban, etoposide, and loperamide.(1,2) |
LUMAKRAS |
| Selected P-glycoprotein (P-gp) Substrates/Selpercatinib SEVERITY LEVEL: 2-Severe Interaction: Action is required to reduce the risk of severe adverse interaction. MECHANISM OF ACTION: Selpercatinib is an inhibitor of the P-glycoprotein (P-gp) transporter and may increase the plasma concentrations of P-gp substrates.(1) CLINICAL EFFECTS: Concurrent use of selpercatinib with P-gp substrates may result in elevated levels of the substrate, increasing the risk for adverse effects.(1) PREDISPOSING FACTORS: None determined. PATIENT MANAGEMENT: The US manufacturer of selpercatinib states that the concurrent use of narrow therapeutic index P-gp substrates should be avoided. If concurrent therapy cannot be avoided, follow recommendations for the narrow therapeutic index P-gp substrate according to the substrate's prescribing information.(1) DISCUSSION: In a study, selpercatinib increased dabigatran's area-under-curve (AUC) by 38% and maximum concentration (Cmax) by 43%.(1) Selected narrow therapeutic index P-gp substrates include: afatinib, betrixaban, bilastine, dabigatran, digoxin, edoxaban, etoposide, everolimus, loperamide, rimegepant, rivaroxaban, sirolimus, and ubrogepant.(1,2) |

There are 1 moderate interactions.
The clinician should assess the patient’s characteristics and take action as needed. Actions required for moderate interactions include, but are not limited to, discontinuing one or both agents, adjusting dosage, altering administration.
| Drug Interaction | Drug Names |
|---|---|
| Loperamide/CYP3A4; CYP2C8; P-glycoprotein (P-gp) Inhibitors SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed. MECHANISM OF ACTION: Inhibitors of CYP3A4, CYP2C8, and/or P-gp may increase loperamide systemic absorption and facilitate entry into central nervous system (CNS).(1) CLINICAL EFFECTS: Concurrent use of inhibitors of CYP3A4, CYP2C8, and/or P-gp may increase levels of loperamide, resulting in respiratory depression.(1) PREDISPOSING FACTORS: None determined. PATIENT MANAGEMENT: Use loperamide with caution in patients receiving inhibitors of CYP3A4, CYP2C8, and/or P-gp. Consider lower doses of loperamide in these patients and monitor for adverse effects. The manufacturer of lonafarnib recommends starting loperamide at a dose of 1 mg and slowly increasing the dose as needed.(2) DISCUSSION: In a randomized, cross-over study in 12 healthy subjects, itraconazole (100 mg twice daily for 5 days - first dose 200 mg), gemfibrozil (600 mg twice daily), and the combination of itraconazole and gemfibrozil (same dosages) increased the area-under-curve (AUC) of single doses of loperamide (4 mg) by 2.9-fold, 1.6-fold, and 4.2-fold, respectively.(3) In a study of healthy subjects, lonafarnib (100 mg twice daily for 5 days) increased the AUC and maximum concentration (Cmax) of single dose loperamide (2 mg) by 299% and 214%, respectively.(3) In a study in 18 healthy males, quinidine increased the AUC of a single dose of loperamide by 2.2-fold and markedly decreased pupil size.(4) In a study in 8 healthy subjects, subjects experienced respiratory depression when a single dose of loperamide (16 mg) was administered with a single dose of quinidine (600 mg) but not when loperamide was administered alone.(6) Loperamide plasma levels increased 2-fold to 3-fold.(5) |

There are no adequate and well-controlled studies using loperamide in pregnant women, and the drug should be used during pregnancy only if potential benefits to the woman justify potential risks to the fetus. Reproduction studies in rats and rabbits using loperamide hydrochloride dosages up to 40 mg/kg daily (43 times the human dosage based on body surface comparison) did not reveal evidence of teratogenicity; however, a dosage of 40 mg/kg daily in rats produced impaired growth and survival of offspring.
Because loperamide is distributed into milk in low concentrations, the drug is not recommended in nursing women.
