HYDROcodone esketamine

Applies to: Gua HC (guaifenesin / hydrocodone) and esketamine

MONITOR CLOSELY: Concomitant use of esketamine with central nervous system (CNS) depressants may increase sedation and impairment of attention, judgment, thinking, reaction speed, and psychomotor skills. In clinical trials, 49% to 61% of esketamine-treated patients developed sedation based on the Modified Observer's Alertness/Sedation scale (MOAA/s), and 0.3% of esketamine-treated patients experienced loss of consciousness (MOAA/s score of 0). In the MOAA/s scale, 5 means "responds readily to name spoken in normal tone" and 0 means "no response after painful trapezius squeeze," and any decrease in MOAA/s from pre-dosing of esketamine is considered to indicate presence of sedation. Dose-related increases in the incidence of sedation were also observed in a fixed-dose study. Additionally, cognitive performance decline was reported in a study in healthy volunteers who received a single intranasal dose of esketamine. Compared to placebo-treated subjects, esketamine-treated subjects required a greater effort to complete cognitive tests at 40 minutes post-dose, although results were comparable between the two groups at 2 hours post-dose. Drowsiness was comparable after 4 hours post-dose.

MANAGEMENT: Caution is advised and patients should be closely monitored during concomitant use of esketamine with CNS depressants or other drugs that can cause sedation or dizziness. Due to the risk of delayed or prolonged sedation and other adverse effects, patients should be monitored for at least 2 hours after esketamine administration, followed by an assessment to determine when the patient is considered clinically stable and ready to leave the healthcare setting. Patients should be instructed not to engage in potentially hazardous activities that require complete mental alertness and motor coordination, such as driving a motor vehicle or operating machinery, until the next day after a restful sleep.

Drug and food interactions

Major

HYDROcodone food

Applies to: Gua HC (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.

esketamine food

Applies to: esketamine

GENERALLY AVOID: Concomitant use of esketamine with central nervous system (CNS) depressants such as alcohol may increase sedation and impairment of attention, judgment, thinking, reaction speed, and psychomotor skills.

ADJUST DOSING INTERVAL: Nausea and vomiting may occur following intranasal administration of esketamine. In clinical studies, nausea and vomiting were reported in approximately 25% and 10% of esketamine-treated patients, respectively.

MANAGEMENT: Patients receiving esketamine should be advised to avoid or limit the consumption of alcohol. In addition, to help prevent nausea and vomiting, patients should be advised not to eat for at least 2 hours before intranasal administration of esketamine and not to drink liquids for at least 30 minutes prior to administration.

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.
