Moderate

HYDROcodone ticagrelor

Applies to: EndaCof-Tab (guaifenesin / hydrocodone) and ticagrelor

MONITOR: Coadministration with opioid agonists may delay and reduce the absorption of orally administered P2Y12 inhibitors (e.g., clopidogrel, prasugrel, ticagrelor). The proposed mechanism may involve opioid-mediated slowed gastric emptying. In one study, IV morphine (5 mg) given immediately prior to a loading dose of clopidogrel (600 mg) decreased the systemic exposure (AUC) and maximum concentration (Cmax) of the active metabolite of clopidogrel by 34% and increased the time to peak concentration (Tmax) of clopidogrel when compared with placebo (105 minutes vs 83 minutes, respectively). In addition, morphine reduced the pharmacodynamic (antiplatelet) effects of clopidogrel. In another study, IV morphine (5 mg) given immediately prior to a loading dose of ticagrelor (180 mg) decreased the AUC of ticagrelor and its active metabolite by approximately 36%, doubled the Tmax of ticagrelor, and reduced the antiplatelet effects of ticagrelor. The clinical relevance of this interaction is unknown. The risks associated with other opioid agonists are also unknown.

MANAGEMENT: Although data are limited, caution is recommended when orally administered P2Y12 inhibitors are given concomitantly with opioid agonists. In acute coronary syndrome patients who require an opioid agonist, the use of a parenteral antiplatelet agent, such as cangrelor, should be considered.

Drug and food interactions

Major

HYDROcodone food

Applies to: EndaCof-Tab (guaifenesin / hydrocodone)

GENERALLY AVOID: Alcohol may potentiate the central nervous system (CNS) depressant effects of opioid analgesics including hydrocodone. 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.

GENERALLY AVOID: Consumption of alcohol while taking some sustained-release formulations of hydrocodone may cause rapid release of the drug, resulting in high systemic levels of hydrocodone that may be potentially lethal. Alcohol apparently can disrupt the release mechanism of some sustained-release formulations. In study subjects, the rate of absorption of hydrocodone from an extended-release formulation was found to be affected by coadministration with 40% alcohol in the fasted state, as demonstrated by an average 2.4-fold (up to 3.9-fold in one subject) increase in hydrocodone peak plasma concentration and a decrease in the time to peak concentration. Alcohol also increased the extent of absorption by an average of 1.2-fold (up to 1.7-fold in one subject).

GENERALLY AVOID: Grapefruit juice may increase the plasma concentrations of hydrocodone. The proposed mechanism is inhibition of CYP450 3A4-mediated metabolism of hydrocodone by certain compounds present in grapefruit. Increased hydrocodone concentrations could conceivably increase or prolong adverse drug effects and may cause potentially fatal respiratory depression.

MANAGEMENT: Patients taking sustained-release formulations of hydrocodone should not consume alcohol or use medications that contain alcohol. In general, potent narcotics such as hydrocodone should not be combined with alcohol. Patients should also avoid consumption of grapefruit or grapefruit juice during treatment with hydrocodone.

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.
