Interactions between your drugs

Moderate

naloxone pentazocine

Applies to: Talwin Nx (naloxone / pentazocine) and Talwin Nx (naloxone / pentazocine)

MONITOR: This warning does not apply to the naloxone component in non-injectable formulations of naloxone-containing combination medicines. Naloxone injection is an antagonist that will reverse the actions of opiates. This reversal can occur when the opiate drug is being used clinically and when it is being abused. Physically dependent patients may experience withdrawal symptoms. Abrupt postoperative opioid reversal has resulted in hypotension, ventricular tachycardia and fibrillation, pulmonary edema, cardiac arrest, encephalopathy, and death.

MANAGEMENT: Patients receiving naloxone injection should be monitored for changes in vital signs, nausea, vomiting, diarrhea, aches, fever, runny nose, sneezing, nervousness, irritability, shivering, abdominal cramps.

Moderate

naloxone naldemedine

Applies to: Talwin Nx (naloxone / pentazocine) and naldemedine

GENERALLY AVOID: Concomitant use of peripherally-acting mu-opioid receptor antagonists, such as methylnaltrexone, naldemedine and naloxegol, with other opioid antagonists may result in additive pharmacologic effects and increased risk of opioid withdrawal. Symptoms consistent with opioid withdrawal including hyperhidrosis, chills, diarrhea, abdominal pain, nausea, vomiting, anxiety, irritability, increased lacrimation, rhinorrhea, and yawning have occurred in patients treated with peripherally-acting mu-opioid receptor antagonists. Patients with disruptions to the blood-brain barrier may be at increased risk.

MANAGEMENT: Concomitant use of peripherally-acting mu-opioid receptor antagonists with other opioid antagonists should generally be avoided.

Drug and food interactions

Moderate

pentazocine food

Applies to: Talwin Nx (naloxone / pentazocine)

MONITOR: Smoking tobacco may decrease the plasma concentrations and effects of pentazocine by enhancing its metabolic clearance.

MANAGEMENT: The possibility of reduced therapeutic effects of pentazocine should be considered in smokers.

Moderate

naldemedine food

Applies to: naldemedine

GENERALLY AVOID: Grapefruit juice may increase the plasma concentrations of naldemedine. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruit. In pharmacokinetic studies, naldemedine systemic exposure (AUC) was increased approximately 90% by the moderate CYP450 3A4 inhibitor fluconazole and nearly 200% by the potent inhibitor itraconazole. The interaction has not been studied with grapefruit juice. In general, the effect of grapefruit juice is concentration-, dose- and preparation-dependent, and can vary widely among brands. Certain preparations of grapefruit juice (e.g., high dose, double strength) have sometimes demonstrated potent inhibition of CYP450 3A4, while other preparations (e.g., low dose, single strength) have typically demonstrated moderate inhibition. Increased exposure to naldemedine may precipitate opioid withdrawal symptoms such as hyperhidrosis, lacrimation, rhinorrhea, chills, diarrhea, abdominal pain, anxiety, insomnia, irritability, restlessness, and yawning.

Food does not significantly affect the overall bioavailability of naldemedine. When administered with a high-fat meal, the rate of naldemedine absorption was decreased, but not the extent. Specifically, naldemedine peak plasma concentration (Cmax) was decreased by approximately 35% and time to achieve Cmax was delayed from 0.75 hours in the fasted state to 2.5 hours in the fed state, while naldemedine AUC was not significantly changed.

MANAGEMENT: Naldemedine may be taken with or without food. Patients should avoid consumption of grapefruit and grapefruit juice during treatment with naldemedine.

Moderate

pentazocine food

Applies to: Talwin Nx (naloxone / pentazocine)

GENERALLY AVOID: Ethanol may potentiate the central nervous system (CNS) depressant effects of opioid analgesics. Concomitant use may result in additive CNS depression and impairment of judgment, thinking, and psychomotor skills. In more severe cases, hypotension, respiratory depression, profound sedation, coma, or even death may occur.

MANAGEMENT: Concomitant use of opioid analgesics with ethanol 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.
