Excipient information presented when available (limited, particularly for generics); consult specific product labeling.
Daliresp: 250 mcg, 500 mcg [contains corn starch]
Brand Names: U.S.
- 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.
Special Populations: Hepatic Function Impairment
The AUC of roflumilast and the N-oxide metabolite were increased by 51% and 24%, respectively, in Child-Pugh class A subjects and by 92% and 41%, respectively, in Child-Pugh class B subjects as compared with healthy subjects. The Cmax of roflumilast and the N-oxide metabolite was increased by 3% and 26%, respectively, in Child-Pugh class A subjects and by 26% and 40%, respectively, in Child-Pugh class B subjects.
Special Populations: Elderly
The roflumilast AUC and Cmax increased 27% and 16%, respectively, and the N-oxide metabolite AUC and Cmax increased 19% and 13%, respectively, in elderly patients.
Special Populations: Gender
The roflumilast and N-oxide metabolite AUC increased 39% and 33%, respectively, in healthy women when compared with healthy men.
Special Populations: Race
The AUC and Cmax of roflumilast and the N-oxide metabolite increased in white, black, Hispanic, and Japanese patients.
Special Populations Note
Cigarette smoking: The AUC of roflumilast in smokers was 13% less than in nonsmokers while the AUC of the N-oxide metabolite in smokers was 17% more than in nonsmokers.
Use: Labeled Indications
COPD: To reduce the risk of COPD exacerbations in patients with severe COPD associated with chronic bronchitis and a history of exacerbations
Limitations of use: Not indicated for the relief of acute bronchospasm
Moderate to severe hepatic impairment (Child-Pugh class B or C).
Canadian labeling: Additional contraindications (not in US labeling): Hypersensitivity to roflumilast or any component of the formulation.
COPD: Oral: 250 mcg once daily for 4 weeks, followed by 500 mcg once daily. Note: An initial dose of 250 mcg once daily is recommended for the first 4 weeks of treatment in an attempt to improve tolerability. However, this is not considered a therapeutic dose and the effect of this approach on long-term tolerability is uncertain.
Dosage adjustment for concomitant therapy: Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.
Refer to adult dosing.
Oral: 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).
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 concomitant therapy when possible. If concomitant therapy cannot be avoided, monitor for reduced clinical effects of the CYP3A4 substrate. Consider therapy modification
Deferasirox: May decrease the serum concentration of CYP3A4 Substrates (High risk with Inducers). Monitor therapy
Enoxacin: May increase the serum concentration of Roflumilast. Monitor therapy
Erdafitinib: 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. Management: Consider avoiding concomitant use of roflumilast and immunosuppressants as recommended by the Canadian product monograph. Inhaled or short-term corticosteroids are unlikely to be problematic. Consider therapy modification
Ivosidenib: May decrease the serum concentration of CYP3A4 Substrates (High risk with Inducers). Monitor therapy
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
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
Tobacco (Smoked): May decrease the serum concentration of Roflumilast. Monitor therapy

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.
• 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.
