Interactions between your drugs

Moderate

amobarbital secobarbital

Applies to: amobarbital / secobarbital and amobarbital / secobarbital

MONITOR: Central nervous system- and/or respiratory-depressant effects may be additively or synergistically increased in patients taking multiple drugs that cause these effects, especially in elderly or debilitated patients. Sedation and impairment of attention, judgment, thinking, and psychomotor skills may increase.

MANAGEMENT: During concomitant use of these drugs, patients should be monitored for potentially excessive or prolonged CNS and respiratory depression. Cautious dosage titration may be required, particularly at treatment initiation. Ambulatory patients should be counseled to avoid hazardous activities requiring mental alertness and motor coordination until they know how these agents affect them, and to notify their physician if they experience excessive or prolonged CNS effects that interfere with their normal activities.

Moderate

amobarbital DOCEtaxel

Applies to: amobarbital / secobarbital and docetaxel

GENERALLY AVOID: Coadministration with inducers of CYP450 3A4 may decrease the plasma concentrations of docetaxel, which is a substrate of the isoenzyme. Rifampin and hyperforin, a component of St. John's wort, have been shown to significantly induce the in vitro metabolism of docetaxel in human hepatocyte cultures. However, clinical pharmacokinetic studies are lacking.

MANAGEMENT: Coadministration of docetaxel with potent CYP450 3A4 inducers such as carbamazepine, dexamethasone, enzalutamide, phenobarbital, phenytoin, rifamycins, and St. John's wort should generally be avoided unless the benefit outweighs the potential risk of docetaxel underexposure. Alternative agents with no or minimal CYP450 3A4 induction potential are recommended whenever possible. If concomitant use is required, close monitoring for signs of reduced therapeutic efficacy is advised. Other known inducers include aminoglutethimide, barbiturates, bexarotene, bosentan, dabrafenib, efavirenz, etravirine, nafcillin, nevirapine, somatrem, somatropin, and various other anticonvulsants, although the extent to which they interact with docetaxel is unknown.

Drug and food interactions

Major

DOCEtaxel food

Applies to: docetaxel

GENERALLY AVOID: Coadministration with inhibitors of CYP450 3A4, such as grapefruit juice, may significantly increase the plasma concentrations of docetaxel, which is a substrate of the isoenzyme. Current data suggest that consumption of large quantities of grapefruit juice inhibit both intestinal and hepatic CYP450 3A4 due to certain compounds present in grapefruit. In a pharmacokinetic study consisting of 7 cancer patients, mean dose-normalized docetaxel systemic exposure (AUC) increased by 2.2-fold and clearance decreased by 49% when intravenous docetaxel was given at a reduced dosage of 10 mg/m2 in combination with the potent CYP450 3A4 inhibitor ketoconazole (200 mg orally once daily for 3 days) compared to docetaxel administered alone at 100 mg/m2. In addition, a case report of a 52-year-old woman with esophageal squamous cell carcinoma receiving a twice weekly chemotherapy regimen including intravenous docetaxel (40 mg/m2) reported that docetaxel AUC increased by 65% compared with the AUC target of 1.96 mg*h/L and clearance decreased by 63%, with a 71% reduction in the patient's neutrophil count. In the absence of other CYP450 3A4 inhibitors, these effects were attributed to daily consumption of 250 mL of grapefruit juice, which the patient had been consuming for at least 3 months. Two weeks after the patient ceased the grapefruit juice, the docetaxel AUC was closer to the target value and the neutrophil count reduction was less than 35%.

MANAGEMENT: The use of docetaxel in combination with grapefruit and grapefruit juice should generally be avoided. If concomitant use is required, a reduced dosage of docetaxel should be considered, particularly if used with large amounts of grapefruit juice, and therapeutic drug monitoring of docetaxel considered per local treatment protocols. Patients should be closely monitored for the development of docetaxel toxicity such as myelosuppression, stomatitis, neurotoxicity (e.g., paraesthesia, dysesthesia, pain), myalgia, asthenia, fluid retention, nausea, vomiting, and diarrhea.

amobarbital food

Applies to: amobarbital / secobarbital

GENERALLY AVOID: Concurrent acute use of barbiturates and ethanol may result in additive CNS effects, including impaired coordination, sedation, and death. Tolerance of these agents may occur with chronic use. The mechanism is related to inhibition of microsomal enzymes acutely and induction of hepatic microsomal enzymes chronically.

MANAGEMENT: The combination of ethanol and barbiturates should be avoided.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
