- Phosphodiesterase-4 Enzyme Inhibitor
Roflumilast and its active N-oxide metabolite selectively inhibit phosphodiesterase-4 (PDE4) leading to an accumulation of cyclic AMP (cAMP) within inflammatory and structural cells important in the pathogenesis of COPD. Anti-inflammatory effects include suppression of cytokine release and inhibition of lung infiltration by neutrophils and other leukocytes. Pulmonary remodeling and mucociliary malfunction are also attenuated.
Vd: 2.9 L/kg
Hepatic via CYP3A4 and CYP1A2 to active N-oxide metabolite; also undergoes conjugation
Urine (~70% as metabolites)
Time to Peak
~1 hour (delayed by food); N-oxide metabolite: ~8 hours
17 hours; N-oxide metabolite: 30 hours
99%; N-oxide metabolite: 97%
Special Populations: Renal Function Impairment
In patients with severe renal impairment, roflumilast and N-oxide metabolite AUCs were decreased by 21% and 7%, respectively, and Cmax was reduced 16% and 12%, respectively.

No dosage adjustment necessary.
Dosing: Hepatic Impairment
Mild impairment (Child-Pugh class A): There are no dosage adjustments provided in the manufacturer's labeling (has not been studied); use with caution.
Moderate to severe impairment (Child-Pugh class B or C): Use is contraindicated.
Administer without regard to meals.
Store at 20°C to 25°C (68°F to 77°F), excursions permitted from 15°C to 30°C (59°F to 86°F).
Bosentan: May decrease the serum concentration of CYP3A4 Substrates (High risk with Inducers). Monitor therapy
Cimetidine: May increase serum concentrations of the active metabolite(s) of Roflumilast. Cimetidine may increase the serum concentration of Roflumilast. Monitor therapy
Ciprofloxacin (Systemic): May increase the serum concentration of Roflumilast. Monitor therapy
CYP3A4 Inducers (Moderate): May decrease the serum concentration of CYP3A4 Substrates (High risk with Inducers). Monitor therapy
CYP3A4 Inducers (Strong): May decrease the serum concentration of Roflumilast. Management: Roflumilast U.S. prescribing information recommends against combining strong CYP3A4 inducers with roflumilast. The Canadian product monograph makes no such recommendation but notes that such agents may reduce roflumilast therapeutic effects. Avoid combination
Dabrafenib: May decrease the serum concentration of CYP3A4 Substrates (High risk with Inducers). Management: Seek alternatives to the CYP3A4 substrate when possible. If concomitant therapy cannot be avoided, monitor clinical effects of the substrate closely (particularly therapeutic effects). Consider therapy modification
Deferasirox: May decrease the serum concentration of CYP3A4 Substrates (High risk with Inducers). Monitor therapy
FluvoxaMINE: May increase serum concentrations of the active metabolite(s) of Roflumilast. FluvoxaMINE may increase the serum concentration of Roflumilast. Monitor therapy
Immunosuppressants: Roflumilast may enhance the immunosuppressive effect of Immunosuppressants. Exceptions: Beclomethasone (Oral Inhalation); Cytarabine (Liposomal); Fluticasone (Oral Inhalation). Consider therapy modification
Loxapine: Agents to Treat Airway Disease may enhance the adverse/toxic effect of Loxapine. More specifically, the use of Agents to Treat Airway Disease is likely a marker of patients who are likely at a greater risk for experiencing significant bronchospasm from use of inhaled loxapine. Management: This is specific to the Adasuve brand of loxapine, which is an inhaled formulation. This does not apply to non-inhaled formulations of loxapine. Avoid combination
Pitolisant: May decrease the serum concentration of CYP3A4 Substrates (High risk with Inducers). Management: Combined use of pitolisant with a CYP3A4 substrate that has a narrow therapeutic index should be avoided. Other CYP3A4 substrates should be monitored more closely when used with pitolisant. Consider therapy modification
RifAMPin: May decrease the serum concentration of Roflumilast. Management: Roflumilast U.S. prescribing information recommends against combining rifampin with roflumilast. The Canadian product monograph makes no such recommendation but notes that rifampin may reduce roflumilast therapeutic effects. Avoid combination
Riociguat: Roflumilast may enhance the hypotensive effect of Riociguat. Management: Riociguat is contraindicated with nonselective phosphodiesterase (PDE) inhibitors and PDE type 5 inhibitors. Other types of PDE inhibitors are not contraindicated, but caution is advised and patients should be monitored for hypotension. Monitor therapy
St John's Wort: May decrease the serum concentration of CYP3A4 Substrates (High risk with Inducers). Management: Consider an alternative for one of the interacting drugs. Some combinations may be specifically contraindicated. Consult appropriate manufacturer labeling. Consider therapy modification

Concerns related to adverse effects:
• Neuropsychiatric: Neuropsychiatric effects (eg, anxiety, depression, insomnia) have been reported with use; rarely, suicidal behavior/ideation and completed suicide were reported. Assess risk versus benefits before prescribing in patients with a history of depression with suicidal behavior/ideations; instruct patients/caregivers to report psychiatric symptoms and consider discontinuation of therapy in such patients.
• Weight loss: Weight loss has occurred; monitor weight regularly. If unexplained or significant weight loss occurs, discontinuation should be considered.
Concurrent drug therapy issues:
• Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information.
• Hepatic impairment: Use with caution in patients with mild impairment (systemic exposure may be increased); use in moderate to severe impairment is contraindicated.
• Appropriate use: Not indicated for relieving acute bronchospasm.
Liver function tests; weight (regularly during therapy); new or worsening insomnia, anxiety, depression, suicidal thoughts, or other mood changes.
Adverse events were observed in some animal reproduction studies.
• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
• Patient may experience dizziness, nausea, diarrhea, headache, back pain, flu-like symptoms, insomnia, or lack of appetite. Have patient report immediately to prescriber signs of depression (suicidal ideation, anxiety, emotional instability, or confusion), severe anxiety, excessive weight loss, agitation, irritability, panic attacks, or mood changes (HCAHPS).
• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
