dextromethorphan inFLIXimab

Applies to: Endacon (dextromethorphan / guaifenesin / phenylephrine) and infliximab
Monitor

Plasma concentrations and effects of drugs that are CYP450 substrates may be altered following the initiation of interleukin (IL) inhibitors, tumor necrosis factor (TNF) blockers, or interferon (IFN) inhibitors in patients with chronic inflammatory diseases. The formation of hepatic CYP450 enzymes may be suppressed during infection and chronic inflammation by increased levels of certain cytokines (e.g., interleukins-1, -6, and -10; tumor necrosis factor alpha; interferons). Immunomodulating therapy that improves inflammation by targeting these cytokines may restore or normalize CYP450 enzyme levels resulting in increased or decreased metabolism of these substrates to active or inactive metabolites. The therapeutic target and disease state being treated may play a role in the significance of this interaction. The most evidence is currently for agents targeting the actions of IL-6 and in disease states with high levels of inflammation such as rheumatoid arthritis, rather than in patients with psoriasis and atopic dermatitis. In vitro studies showed that tocilizumab, an IL-6 inhibitor, has the potential to impact expression of various hepatic microsomal enzymes including CYP450 1A2, 2B6, 2C9, 2C19, 2D6, and 3A4. Its effects on CYP450 2C8 or transporters is unknown. In vivo studies with omeprazole (a substrate of CYP450 2C19 and 3A4) and simvastatin (a substrate of CYP450 3A4 and OATP 1B1) showed decreases of up to 28% and 57% in systemic exposure, respectively, one week following a single dose of tocilizumab. Likewise, simvastatin and simvastatin acid exposures decreased by 45% and 36%, respectively, in 17 patients with rheumatoid arthritis one week following a single 200 mg subcutaneous dose of sarilumab, another IL-6 inhibitor. A role for other interleukins such as IL-12, IL-17A, or IL-23 in the regulation of CYP450 enzymes has not been clearly established, and it is not known whether antagonists of these interleukins would similarly affect CYP450 metabolism. For example, in drug interaction studies, the IL-23 antagonists risankizumab and tildrakizumab, and the IL-17A antagonist ixekizumab demonstrated no clinically significant effects on the activity of CYP450 isoenzymes 1A2, 3A, 2C19, 2D6, or 2C9. Similarly, data evaluating this interaction are not available for the TNF blockers certolizumab and etanercept.

Management

Caution is advised when treatments targeting cytokines such as interleukins, tumor necrosis factors, or interferons are prescribed to patients receiving concomitant drugs that are CYP450 substrates, particularly those with narrow therapeutic ranges (e.g., antiarrhythmics, anticonvulsants, immunosuppressants, theophylline) or sensitive substrates where decreases in plasma levels may be significant or undesirable (e.g., oral contraceptives, statins, benzodiazepines, opioids). Clinical and/or laboratory monitoring should be considered following the initiation or withdrawal of such treatments, and the dosage(s) of the CYP450 substrate(s) adjusted accordingly. Clinicians should note that the effects of IL inhibitors, TNF blockers, and IFN inhibitors on CYP450 activities may persist for several weeks after stopping therapy. Individual product labeling for these products should be consulted for specific recommendations.

phenylephrine Caffeine

Applies to: Endacon (dextromethorphan / guaifenesin / phenylephrine)
Monitor

Coadministration of two or more sympathomimetic or noradrenergic agents may increase the risk of nervousness, irritability, tachycardia, and/or increased blood pressure. Central nervous system (CNS) stimulants, particularly amphetamines, can potentiate the adrenergic response to vasopressors and other sympathomimetic and/or noradrenergic agents, including norepinephrine transporter inhibitors. Additive increases in blood pressure and heart rate may occur due to enhanced peripheral sympathetic activity.

Management

Caution is advised if two or more sympathomimetic or noradrenergic agents are coadministered. Pulse and blood pressure should be closely monitored. Consultation with individual product labeling, as well as relevant institutional protocols, may be advisable for further guidance.

Discontinuation of therapy should be considered in patients with confirmed significant hematologic abnormalities.

Cardiovascular Conditions and Disorders

Major:

Endacon

The phenylephrine in Endacon has a major potential interaction with Cardiovascular Conditions and Disorders.

Sympathomimetic agents may cause adverse cardiovascular effects, particularly when used in high dosages and/or in susceptible patients. In cardiac tissues, these agents may produce positive chronotropic and inotropic effects via stimulation of beta- 1 adrenergic receptors. Cardiac output, oxygen consumption, and the work of the heart may be increased. In the peripheral vasculature, vasoconstriction may occur via stimulation of alpha-1 adrenergic receptors. Palpitations, tachycardia, arrhythmia, hypertension, reflex bradycardia, coronary occlusion, cerebral vasculitis, myocardial infarction, cardiac arrest, and death have been reported. Some of these agents, particularly ephedra alkaloids (ephedrine, ma huang, phenylpropanolamine), may also predispose patients to hemorrhagic and ischemic stroke. Therapy with sympathomimetic agents should generally be avoided or administered cautiously in patients with sensitivity to sympathomimetic amines, hyperthyroidism, or underlying cardiovascular or cerebrovascular disorders. These agents should not be used in patients with severe coronary artery disease or severe/uncontrolled hypertension.

Central Nervous System Disorders

Major:

infliximab

inFLIXimab has a major potential interaction with Central Nervous System Disorders.

The use of TNF blocking agents has been associated with rare cases of CNS manifestations of systemic vasculitis, seizure and new onset or exacerbation of clinical symptoms and/or radiographic evidence of central nervous system demyelinating disorders, including multiple sclerosis and optic neuritis, and peripheral demyelinating disorders, including Guillain-Barré syndrome. Care should be exercised when considering the use of these agents in patients with neurologic disorders and discontinuing the agent is recommended if these disorders develop during therapy.

Cerebrovascular Insufficiency

Major:

Endacon

The phenylephrine in Endacon has a major potential interaction with Cerebrovascular Insufficiency.

Cardiac output, oxygen consumption, and the work of the heart may be increased. In the peripheral vasculature, vasoconstriction may occur via stimulation of alpha-1 adrenergic receptors. Palpitations, tachycardia, arrhythmia, hypertension, reflex bradycardia, coronary occlusion, cerebral vasculitis, myocardial infarction, cardiac arrest, and death have been reported. Some of these agents, particularly ephedra alkaloids (ephedrine, ma huang, phenylpropanolamine), may also predispose patients to hemorrhagic and ischemic stroke. Therapy with sympathomimetic agents should generally be avoided or administered cautiously in patients with sensitivity to sympathomimetic amines, hyperthyroidism, or underlying cardiovascular or cerebrovascular disorders. These agents should not be used in patients with severe coronary artery disease or severe/uncontrolled hypertension.

COPD

Moderate:

infliximab

inFLIXimab has a moderate potential interaction with COPD.

In studies, patients with moderate to severe chronic obstructive pulmonary disease (COPD) treated with infliximab developed more malignancies, the majority of lung or head and neck origin than those treated with placebo. Caution should be exercised when considering the use of infliximab in patients with moderate to severe COPD.

Diabetes Mellitus

Moderate:

Endacon

The phenylephrine in Endacon has a moderate potential interaction with Diabetes Mellitus.

Sympathomimetic agents may cause increases in blood glucose concentrations. These effects are usually transient and slight but may be significant with dosages higher than those normally recommended. Therapy with sympathomimetic agents should be administered cautiously in patients with diabetes mellitus. Closer monitoring of blood glucose concentrations may be appropriate.

Glaucoma/Intraocular Hypertension

Moderate:

Endacon

The phenylephrine in Endacon has a moderate potential interaction with Glaucoma/Intraocular Hypertension.

Sympathomimetic agents can induce transient mydriasis via stimulation of alpha-1 adrenergic receptors. In patients with anatomically narrow angles or narrow-angle glaucoma, pupillary dilation can provoke an acute attack. In patients with other forms of glaucoma, mydriasis may occasionally increase intraocular pressure. Therapy with sympathomimetic agents should be administered cautiously in patients with or predisposed to glaucoma, particularly narrow-angle glaucoma.

Heart Failure

Major:

infliximab

inFLIXimab has a major potential interaction with Heart Failure.

In a study of patients with moderate to severe heart failure (New York Heart Association [NYHA] Functional Class III/IV), an increase incidence of death and hospitalization due to worsening of heart failure was observed after treatment with infliximab at 10 mg/kg. Infliximab at doses > 5 mg/kg is contraindicated in patients with moderate to severe heart failure.

History, Skin Cancer

Major:

infliximab

inFLIXimab has a major potential interaction with History, Skin Cancer.

In clinical trials malignancies have been observed in patients receiving TNF-blockers agents. Patients with psoriasis should be monitored for non-melanoma skin cancers (NMSCs), particularly those patients who have had prior prolonged phototherapy treatment. Melanoma and Merkel cell carcinoma have been reported in patients treated with TNF blocker therapy. Periodic skin examination is recommended for all patients, particularly those with risk factors for skin cancer. Postmarketing cases of fatal hepatosplenic T-cell lymphoma (HSTCL) have been reported in patients treated with TNF blockers. Caution should be exercised when considering these agents in the treatment of patients with a history of malignancies or in continuing treatment in patients who develop malignancies while receiving these agents.

Hyperthyroidism

Major:

Infection

Major:

infliximab

inFLIXimab has a major potential interaction with Infection.

There have been reports of serious infections, including sepsis and opportunistic infections due to bacterial, mycobacterial, invasive fungal, viral, parasitic, or other opportunistic pathogens including aspergillosis, blastomycosis, candidiasis, coccidioidomycosis, histoplasmosis, legionellosis, listeriosis, pneumocystosis and tuberculosis with TNF blockers. Treatment with these agents should not be initiated in patients with an active infection, including clinically important localized infections. Caution and close monitoring is recommended when considering their use in patients with a history of recurrent infections, underlying conditions which may predispose them to infections, or chronic, latent, or localized infections. Administration of these agents should be discontinued if a patient develops a serious infection or sepsis.

Infectious Hepatitis

Moderate:

infliximab

inFLIXimab has a moderate potential interaction with Infectious Hepatitis.

The use of TNF blockers has been associated with reactivation of hepatitis B, in some cases fatal, in patients who were previously infected with the hepatitis B virus (HBV). Therefore, screening for viral hepatitis should be performed in accordance with published guidelines before starting therapy with these agents. Monitor patients at risk or with evidence of current or prior HBV infection for clinical and laboratory signs of hepatitis or HBV reactivation. Prescribers should exercise caution in prescribing TNF blockers in patients previously infected with HBV. It is recommended to monitor patients with evidence of current or prior HBV infection for clinical and laboratory signs of hepatitis or HBV reactivation during and for several months following therapy. In patients who develop HBV reactivation, therapy should be stopped and antiviral therapy with appropriate supportive treatment should be initiated. The safety of resuming these agents after HBV reactivation is controlled is not known. Therefore, prescribers should weigh the risks and benefits when considering resumption of therapy.

Liver Disease

Major:

infliximab

inFLIXimab has a major potential interaction with Liver Disease.

Severe hepatic reactions, including acute liver failure, jaundice, hepatitis and cholestasis, have been reported with the use of infliximab. Infliximab should be discontinued if jaundice and/or marked liver enzyme elevations (e.g., greater than or equal to 5 times the upper limit of normal) develop and a thorough investigation of the abnormality should be undertaken.

Lymphoma

Major:

infliximab

inFLIXimab has a major potential interaction with Lymphoma.
