Where does this data come from?
NADAC (National Average Drug Acquisition Cost) is the CMS weekly pharmacy-acquisition-cost survey — what pharmacies pay. ASP (Average Sales Price) is the CMS Medicare Part B drug-payment file, published quarterly. Medicaid pays is computed by us from CMS State Drug Utilization Data (total reimbursed ÷ units, trailing 12 months) — gross of rebates and inclusive of dispensing fees, so it reflects what Medicaid paid, not an acquisition cost. Medicare drug plans pay is the median negotiated point-of-sale unit cost across plans listing this NDC in the CMS quarterly Prescription Drug Plan pricing files, before rebates. The VA pays is the federal contract price (FSS, and the statutory Big 4 ceiling where listed) from the VA National Acquisition Center pharmaceutical price file. All are free public government data; each measures a different payer, so the figures are not directly comparable.

⚠️ Warnings and Cautions ~3 min read ▾

5 WARNINGS AND PRECAUTIONS • Acute Bronchospasm: Do not use for the relief of acute bronchospasm. ( 5.1 ) • Psychiatric Events including Suicidality: Advise patients, their caregivers, and families to be alert for the emergence or worsening of insomnia, anxiety, depression, suicidal thoughts or other mood changes, and if such changes occur to contact their healthcare provider. Carefully weigh the risks and benefits of treatment with DALIRESP in patients with a history of depression and/or suicidal thoughts or behavior.

( 5.2 ) • Weight Decrease: Monitor weight regularly. If unexplained or clinically significant weight loss occurs, evaluate weight loss and consider discontinuation of DALIRESP. ( 5.3 ) • Drug Interactions: Use with strong cytochrome P450 enzyme inducers (e.g., rifampicin, phenobarbital, carbamazepine, phenytoin) is not recommended.

( 5.4 )

5.1Treatment of Acute Bronchospasm DALIRESP is not a bronchodilator and should not be used for the relief of acute bronchospasm.

5.2Psychiatric Events including Suicidality Treatment with DALIRESP is associated with an increase in psychiatric adverse reactions. In 8 controlled clinical trials 5.9% (263) of patients treated with DALIRESP 500 mcg daily reported psychiatric adverse reactions compared to 3.3% (137) treated with placebo. The most commonly reported psychiatric adverse reactions were insomnia, anxiety, and depression which were reported at higher rates in those treated with DALIRESP 500 mcg daily (2.4%, 1.4%, and 1.2% for DALIRESP versus 1.0%, 0.9%, and 0.9% for placebo, respectively) [see Adverse Reactions (6.1) ] .

Instances of suicidal ideation and behavior, including completed suicide, have been observed in clinical trials. Three patients experienced suicide-related adverse reactions (one completed suicide and two suicide attempts) while receiving DALIRESP compared to one patient (suicidal ideation) who received placebo. One patient completed suicide while receiving DALIRESP in Trial 9 [see Clinical Studies (14.1) ] , which assessed the effect of adding roflumilast to a fixed-dose combination (FDC) of ICS/LABA on rates of exacerbations in COPD patients over 1 year of treatment.

Cases of suicidal ideation and behavior, including completed suicide, have been observed in the post-marketing setting in patients with or without a history of depression. Before using DALIRESP in patients with a history of depression and/or suicidal thoughts or behavior, prescribers should carefully weigh the risks and benefits of treatment with DALIRESP in such patients. Patients, their caregivers, and families should be advised of the need to be alert for the emergence or worsening of insomnia, anxiety, depression, suicidal thoughts or other mood changes, and if such changes occur to contact their healthcare provider.

Prescribers should carefully evaluate the risks and benefits of continuing treatment with DALIRESP if such events occur.

5.3Weight Decrease Weight loss was a common adverse reaction in DALIRESP clinical trials and was reported in 7.5% (331) of patients treated with DALIRESP 500 mcg once daily compared to 2.1% (89) treated with placebo [see Adverse Reactions (6.1) ] . In addition to being reported as adverse reactions, weight was prospectively assessed in two placebo-controlled clinical trials of one year duration. In these studies, 20% of patients receiving roflumilast experienced moderate weight loss (defined as between 5-10% of body weight) compared to 7% of patients who received placebo.

In addition, 7% of patients who received roflumilast compared to 2% of patients receiving placebo experienced severe (>10% body weight) weight loss. During follow-up after treatment discontinuation, the majority of patients with weight loss regained some of the weight they had lost while receiving DALIRESP. Patients treated with DALIRESP should have their weight monitored regularly.

If unexplained or clinically significant weight loss occurs, weight loss should be evaluated, and disc… [Excerpted — this section continues on DailyMed.]

6 ADVERSE REACTIONS The following adverse reactions are described in greater detail in other sections: • Psychiatric Events Including Suicidality [see Warnings and Precautions (5.2) ] • Weight Decrease [see Warnings and Precautions (5.3) ] Most common adverse reactions (≥2%) are diarrhea, weight decrease, nausea, headache, back pain, influenza, insomnia, dizziness and decreased appetite. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact AstraZeneca at 1-800-236-9933 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch .

6.1Adverse Reactions in Clinical Studies Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The safety data described below reflect exposure of 4438 patients to DALIRESP 500 mcg once daily in four 1-year placebo-controlled trials, two 6-month placebo-controlled trials, and two 6-month drug add-on trials [see Clinical Studies (14.1) ].

In these trials, 3136 and 1232 COPD patients were exposed to DALIRESP 500 mcg once daily for 6 months and 1 year, respectively. The population had a median age of 64 years (range 40-91), 73% were male, 92.9% were Caucasian, and had COPD with a mean pre-bronchodilator forced expiratory volume in one second (FEV 1 ) of 8.9 to 89.1% predicted. In these trials, 68.5% of the patients treated with DALIRESP reported an adverse reaction compared with 65.3% treated with placebo.

The proportion of patients who discontinued treatment due to adverse reaction was 14.8% for DALIRESP-treated patients and 9.9% for placebo-treated patients. The most common adverse reactions that led to discontinuation of DALIRESP were diarrhea (2.4%) and nausea (1.6%). Serious adverse reactions, whether considered drug-related or not by the investigators, which occurred more frequently in DALIRESP-treated patients include diarrhea, atrial fibrillation, lung cancer, prostate cancer, acute pancreatitis, and acute renal failure.

Table 1 summarizes the adverse reactions reported by ≥2% of patients in the DALIRESP group in 8 controlled COPD clinical trials. Table 1: Adverse Reactions Reported by ≥2% of Patients Treated with DALIRESP 500 mcg daily and Greater Than Placebo Treatment Adverse Reactions DALIRESP Placebo (Preferred Term) ( N= 4438) (N= 4192) n (%) n (%) Diarrhea 420 (9.5) 113 (2.7) Weight decreased 331 (7.5) 89 (2.1) Nausea 209 (4.7) 60 (1.4) Headache 195 (4.4) 87 (2.1) Back pain 142 (3.2) 92 (2.2) Influenza 124 (2.8) 112 (2.7) Insomnia 105 (2.4) 41 (1.0) Dizziness 92 (2.1) 45 (1.1) Decreased appetite 91 (2.1) 15 (0.4) Adverse reactions that occurred in the DALIRESP group at a frequency of 1 to 2% where rates exceeded that in the placebo group include: Gastrointestinal disorders - abdominal pain, dyspepsia, gastritis, vomiting Infections and infestations - rhinitis, sinusitis, urinary tract infection Musculoskeletal and connective tissue disorders - muscle spasms Nervous system disorders - tremor Psychiatric disorders - anxiety, depression The safety profile of roflumilast reported during Trial 9 was consistent with the key pivotal studies.

6.2Postmarketing Experience The following adverse reactions have been identified from spontaneous reports of DALIRESP received worldwide and have not been listed elsewhere. These adverse reactions have been chosen for inclusion due to a combination of seriousness, frequency of reporting or potential causal connection to DALIRESP. Because these adverse reactions were reported voluntarily from a population of uncertain size, it is not possible to estimate their frequency or establish a causal relationship to DALIRESP exposure: hypersensitivity reactions (including angioedema, urticaria, and rash), gynecomastia.

🔄 Drug Interactions ~1 min read ▾

7 DRUG INTERACTIONS A major step in roflumilast metabolism is the N-oxidation of roflumilast to roflumilast N-oxide by CYP3A4 and CYP1A2 [see Clinical Pharmacology (12.3) ] . Use with inhibitors of CYP3A4 or dual inhibitors of CYP3A4 and CYP1A2 (e.g., erythromycin, ketoconazole, fluvoxamine, enoxacin, cimetidine) will increase roflumilast systemic exposure and may result in increased adverse reactions. The risk of such concurrent use should be weighed carefully against benefit.

( 7.2 )

7.1Drugs that Induce Cytochrome P450 (CYP) Enzymes Strong cytochrome P450 enzyme inducers decrease systemic exposure to roflumilast and may reduce the therapeutic effectiveness of DALIRESP. Therefore the use of strong cytochrome P450 inducers (e.g., rifampicin, phenobarbital, carbamazepine, and phenytoin) with DALIRESP is not recommended [see Warnings and Precautions (5.4) and Clinical Pharmacology (12.3) ].

7.2Drugs that Inhibit Cytochrome P450 (CYP) Enzymes The co-administration of DALIRESP (500 mcg) with CYP3A4 inhibitors or dual inhibitors that inhibit both CYP3A4 and CYP1A2 simultaneously (e.g., erythromycin, ketoconazole, fluvoxamine, enoxacin, cimetidine) may increase roflumilast systemic exposure and may result in increased adverse reactions. The risk of such concurrent use should be weighed carefully against benefit [see Clinical Pharmacology (12.3) ].

7.3Oral Contraceptives Containing Gestodene and Ethinyl Estradiol The co-administration of DALIRESP (500 mcg) with oral contraceptives containing gestodene and ethinyl estradiol may increase roflumilast systemic exposure and may result in increased side effects. The risk of such concurrent use should be weighed carefully against benefit [see Clinical Pharmacology (12.3) ].

👥 Use in Specific Populations ~3 min read ▾

8 USE IN SPECIFIC POPULATIONS Nursing Mothers: DALIRESP should not be used by women who are nursing as excretion of roflumilast and/or its metabolites into human milk is probable and there are no human studies that have investigated effects of DALIRESP on breast-fed infants. ( 8.2 )

8.1Pregnancy Risk Summary There are no randomized clinical studies of DALIRESP in pregnant women. In animal reproductive toxicity studies, DALIRESP administered to pregnant rats and rabbits during the period of organogenesis produced no fetal structural abnormalities. The highest DALIRESP dose in these studies was approximately 30 and 26 times, respectively, the maximum recommended human dose (MRHD).

DALIRESP induced post-implantation loss in rats at doses greater than or equal to approximately 10 times the MRHD. DALIRESP induced stillbirth and decreased pup viability in mice at doses corresponding to approximately 16 and 49 times, respectively, the MRHD. DALIRESP has been shown to adversely affect pup post-natal development when dams were treated with the drug during pregnancy and lactation periods in mice at doses corresponding to 49 times the MRHD ( see Data ).

The background risk of major birth defects and miscarriage for the indicated population is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. Clinical Considerations Labor and delivery DALIRESP should not be used during labor and delivery.

There are no human studies that have investigated effects of DALIRESP on preterm labor or labor at term; however, animal studies showed that DALIRESP disrupted the labor and delivery process in mice. Data Animal data In an embryo-fetal development study, pregnant rats were dosed orally during the period of organogenesis with up to 1.8 mg/kg/day DALIRESP (approximately 30 times the MRHD on an AUC basis). No evidence of structural abnormalities or effects on survival rates were observed.

DALIRESP did not affect embryo-fetal development at approximately 3 times the MRHD (on a mg/m 2 basis at a maternal oral dose of 0.2 mg/kg/day). In a fertility and embryo-fetal development study, male rats were dosed orally with up to 1.8 mg/kg/day DALIRESP for 10 weeks and females for two weeks prior to pairing and throughout the organogenesis period. DALIRESP induced pre- and post-implantation loss at doses greater than or equal to approximately 10 times the MRHD (on a mg/m2 basis at maternal oral doses greater than or equal to 0.6 mg/kg/day).

DALIRESP did not cause fetal structural abnormalities at exposures up to approximately 29 times the MRHD (on an AUC basis at maternal oral doses up to 1.8 mg/kg/day). In an embryo-fetal development study in rabbits, pregnant does were dosed orally with 0.8 mg/kg/day DALIRESP during the period of organogenesis. DALIRESP did not cause fetal structural abnormalities at exposures approximately 26 times the MRHD (on a mg/m 2 basis at maternal oral doses of 0.8 mg/kg/day).

In pre- and post-natal developmental studies in mice, dams were dosed orally with up to 12 mg/kg/day DALIRESP during the period of organogenesis and lactation. DALIRESP induced stillbirth and decreased pup viability at doses corresponding to approximately 16 and 49 times, respectively, the MRHD (on a mg/m 2 basis at maternal doses >2 mg/kg/day and 6 mg/kg/day, respectively). DALIRESP induced delivery retardation in pregnant mice at doses greater or equal to approximately 16 times the MRHD (on a mg/m 2 basis at maternal doses >2 mg/kg/day).

DALIRESP decreased pup rearing frequencies at approximately 49 times the MRHD (on a mg/m 2 basis at a maternal dose of 6 mg/kg/day) during pregnancy and lactation. DALIRESP also decreased survival and forelimb grip reflex and delayed pinna detachment in mouse pups at approximately 97 times the MRHD (on a mg/m 2 basis at a maternal dose of 12 mg/kg/day).

8.1Pregnancy Risk Summary There are no randomized clinical studies of DALIRESP in pregnant women. In animal reproductive toxicity studies, DALIRESP administered to pregnant rats and rabbits during the period of organogenesis produced no fetal structural abnormalities. The highest DALIRESP dose in these studies was approximately 30 and 26 times, respectively, the maximum recommended human dose (MRHD).

DALIRESP induced post-implantation loss in rats at doses greater than or equal to approximately 10 times the MRHD. DALIRESP induced stillbirth and decreased pup viability in mice at doses corresponding to approximately 16 and 49 times, respectively, the MRHD. DALIRESP has been shown to adversely affect pup post-natal development when dams were treated with the drug during pregnancy and lactation periods in mice at doses corresponding to 49 times the MRHD ( see Data ).

The background risk of major birth defects and miscarriage for the indicated population is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. Clinical Considerations Labor and delivery DALIRESP should not be used during labor and delivery.

There are no human studies that have investigated effects of DALIRESP on preterm labor or labor at term; however, animal studies showed that DALIRESP disrupted the labor and delivery process in mice. Data Animal data In an embryo-fetal development study, pregnant rats were dosed orally during the period of organogenesis with up to 1.8 mg/kg/day DALIRESP (approximately 30 times the MRHD on an AUC basis). No evidence of structural abnormalities or effects on survival rates were observed.

DALIRESP did not affect embryo-fetal development at approximately 3 times the MRHD (on a mg/m 2 basis at a maternal oral dose of 0.2 mg/kg/day).

🧒 Pediatric Use 23 words ▾

8.4Pediatric Use COPD does not normally occur in children. The safety and effectiveness of DALIRESP in pediatric patients have not been established.

🧓 Geriatric Use 97 words ▾

8.5Geriatric Use Of the 4438 COPD subjects exposed to DALIRESP for up to 12 months in 8 controlled clinical trials, 2022 were >65 years of age and 471 were >75 years of age. No overall differences in safety or effectiveness were observed between these subjects and younger subjects and other reported clinical experience has not identified differences in responses between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out. Based on available data for roflumilast, no adjustment of dosage in geriatric patients is warranted [see Clinical Pharmacology (12.3) ].

🆘 Overdosage 108 words ▾

10 OVERDOSAGE

10.1Human Experience No case of overdose has been reported in clinical studies with DALIRESP. During the Phase I studies of DALIRESP, the following symptoms were observed at an increased rate after a single oral dose of 2500 mcg and a single dose of 5000 mcg: headache, gastrointestinal disorders, dizziness, palpitations, lightheadedness, clamminess, and arterial hypotension.

10.2Management of Overdose In case of overdose, patients should seek immediate medical help. Appropriate supportive medical care should be provided. Since roflumilast is highly protein bound, hemodialysis is not likely to be an efficient method of drug removal. It is not known whether roflumilast is dialyzable by peritoneal dialysis.

12 CLINICAL PHARMACOLOGY

12.1Mechanism of Action Roflumilast and its active metabolite (roflumilast N-oxide) are selective inhibitors of phosphodiesterase 4 (PDE4). Roflumilast and roflumilast N-oxide inhibition of PDE4 (a major cyclic-3′,5′-adenosine monophosphate (cyclic AMP)-metabolizing enzyme in lung tissue) activity leads to accumulation of intracellular cyclic AMP. While the specific mechanism(s) by which DALIRESP exerts its therapeutic action in COPD patients is not well defined, it is thought to be related to the effects of increased intracellular cyclic AMP in lung cells.

12.2Pharmacodynamics In COPD patients, 4‑week treatment with DALIRESP 500 mcg oral once daily reduced sputum neutrophils and eosinophils by 31%, and 42%, respectively. In a pharmacodynamic study in healthy volunteers, DALIRESP 500 mcg once daily reduced the number of total cells, neutrophils and eosinophils found in bronchoalveolar lavage fluid following segmental pulmonary lipopolysaccharide (LPS) challenge by 35%, 38% and 73%, respectively. The clinical significance of these findings is unknown.

12.3Pharmacokinetics Absorption The absolute bioavailability of roflumilast following a 500 mcg oral dose is approximately 80%. Maximum plasma concentrations (C max ) of roflumilast typically occur approximately one hour after dosing (ranging from 0.5 to 2 hours) in the fasted state while plateau-like maximum concentrations of the N-oxide metabolite are reached in approximately eight hours (ranging from 4 to 13 hours). Food has no effect on total drug absorption, but delays time to maximum concentration (T max ) of roflumilast by one hour and reduces C max by approximately 40%, however, C max and T max of roflumilast N-oxide are unaffected.

An in vitro study showed that roflumilast and roflumilast N-oxide did not inhibit P-gp transporter. Distribution Plasma protein binding of roflumilast and its N-oxide metabolite is approximately 99% and 97%, respectively. Volume of distribution for single‑dose 500 mcg roflumilast is about

2.9L/kg. Studies in rats with radiolabeled roflumilast indicate low penetration across the blood-brain barrier. Metabolism Roflumilast is extensively metabolized via Phase I (cytochrome P450) and Phase II (conjugation) reactions.

The N-oxide metabolite is the only major metabolite observed in the plasma of humans. Together, roflumilast and roflumilast N-oxide account for the majority (87.5%) of total dose administered in plasma. In urine, roflumilast was not detectable while roflumilast N-oxide was only a trace metabolite (less than 1%).

Other conjugated metabolites such as roflumilast N-oxide glucuronide and 4-amino-3,5-dichloropyridine N-oxide were detected in urine. While roflumilast is three times more potent than roflumilast N-oxide at inhibition of the PDE4 enzyme in vitro , the plasma AUC of roflumilast N-oxide on average is about 10-fold greater than the plasma AUC of roflumilast. In vitro studies and clinical drug-drug interaction studies suggest that the biotransformation of roflumilast to its N-oxide metabolite is mediated by CYP1A2 and 3A4.

Based on further in vitro results in human liver microsomes, therapeutic plasma concentrations of roflumilast and roflumilast N-oxide do not inhibit CYP1A2, 2A6, 2B6, 2C8, 2C9, 2C19, 2D6, 2E1, 3A4/5, or 4A9/11. Therefore, there is a low probability of relevant interactions with substances metabolized by these P450 enzymes. In addition, in vitro studies demonstrated no induction of the CYP1A2, 2A6, 2C9, 2C19, or 3A4/5 and only a weak induction of CYP2B6 by roflumilast.

Elimination The plasma clearance after short-term intravenous infusion of roflumilast is on average about

9.6L/h. Following an oral dose, the median plasma effective half-life of roflumilast and its N-oxide metabolite are approximately 17 and 30 hours, respectively. Steady state plasma concentrations of roflumilast and its N-oxide metabolite are reached after approximately 4 days for roflumilast and 6 days for roflumil… [Excerpted — this section continues on DailyMed.]

💬 Information for Patients ~1 min read ▾

17 PATIENT COUNSELING INFORMATION Advise the patient to read the FDA-approved patient labeling (Medication Guide). Bronchospasm DALIRESP is not a bronchodilator and should not be used for immediate relief of breathing problems (i.e., as a rescue medication). Psychiatric Events including Suicidality Treatment with DALIRESP is associated with an increase in psychiatric adverse reactions.

Cases of suicidal ideation and behavior, including completed suicide, have been observed in the post-marketing setting in patients with or without a history of depression. The risks and benefits of treatment with DALIRESP in patients with a history of depression and/or suicidal thoughts or behavior should be carefully considered. Advise patients, caregivers, and families to be alert for the emergence or worsening of insomnia, anxiety, depression, suicidal thoughts or other mood changes, and if such changes occur to contact their healthcare provider so that the risks and benefits of continuing treatment with DALIRESP may be considered [see Warnings and Precautions (5.2) ].

Weight Decrease Weight loss was a common adverse reaction in DALIRESP clinical trials. During follow-up after treatment discontinuation, the majority of patients with weight loss regained some of the weight they had lost while receiving DALIRESP. Advise patients treated with DALIRESP to have their weight monitored regularly.

If unexplained weight loss occurs, patients should inform their healthcare provider so that the weight loss can be evaluated, as discontinuation of DALIRESP may need to be considered [see Warnings and Precautions (5.3) ] . Drug Interactions The use of cytochrome P450 enzyme inducers resulted in a reduction in exposure which may result in decreased therapeutic effectiveness of DALIRESP. The use of strong cytochrome P450 enzyme inducers (e.g., rifampicin, phenobarbital, carbamazepine, phenytoin) with DALIRESP is not recommended [see Drug Interactions (7.1) and Clinical Pharmacology (12.3) ] .

🔬 Clinical Studies ~3 min read ▾

14 CLINICAL STUDIES

14.1Chronic Obstructive Pulmonary Disease (COPD) The efficacy and safety of DALIRESP (roflumilast) in COPD was evaluated in 8 randomized, double-blind, controlled, parallel‑group clinical trials in 9394 adult patients (4425 receiving DALIRESP 500 mcg) 40 years of age and older with COPD. Of the 8 trials, two were placebo-controlled dose selection trials (Trials 1 and 2) of 6 months’ duration that evaluated the efficacy of DALIRESP 250 mcg and 500 mcg once daily, four were placebo-controlled 1-year trials (Trials 3, 4, 5, and 6) primarily designed to evaluate the efficacy of DALIRESP on COPD exacerbations, and two were 6-month efficacy trials (Trials 7 and 8) which assessed the effect of DALIRESP as add-on therapy to a long-acting beta agonist or long-acting anti-muscarinic.

The 8 trials enrolled patients with nonreversible obstructive lung disease (FEV 1 /FVC ≤70% and ≤12% or 200 mL improvement in FEV 1 in response to 4 puffs of albuterol/salbutamol) but the severity of airflow obstruction at baseline was different among the trials. Patients enrolled in the dose selection trials had the full range of COPD severity (FEV 1 30-80% predicted); median age of 63 years, 73% male, and 99% Caucasian. Patients enrolled in the four exacerbation trials had severe COPD (FEV 1 ≤50% predicted); median age of 64 years, 74% male, and 90% Caucasian.

Patients enrolled in the two 6-month efficacy trials had moderate to severe COPD (FEV 1 40-70% predicted); median age of 65 years, 68% male, and 97% Caucasian. COPD exacerbations and lung function (FEV 1 ) were co-primary efficacy outcome measures in the four 1-year trials. In the two 6-month supportive efficacy trials, lung function (FEV 1 ) alone was the primary efficacy outcome measure.

The two 6-month dose-selection efficacy trials (Trials 1 and 2) explored doses of 250 mcg and 500 mcg once daily in a total of 1929 patients (751 and 724 on DALIRESP 250 and 500 mcg, respectively). The selection of the 500 mcg dose was primarily based on nominal improvements in lung function (FEV 1 ) over the 250 mcg dose. The once‑daily dosing regimen was primarily based on the determination of a plasma half-life of 17 hours for roflumilast and 30 hours for its active metabolite roflumilast N-oxide [see Clinical Pharmacology (12.3) ] .

An additional placebo-controlled 1-year trial (Trial 9) evaluated the effect of DALIRESP 500 mcg on COPD exacerbations when added to a fixed-dose combination (FDC) product containing an inhaled corticosteroid and long-acting beta agonist (ICS/LABA). At screening, patients were required to have two or more exacerbations in the previous year. This trial randomized a total of 2354 patients (1178 randomized to DALIRESP, 1176 to placebo).

Approximately 60% of the patients enrolled had severe COPD (postbronchodilator FEV 1 30%-50% of predicted) associated with chronic bronchitis and 39% had very severe COPD (postbronchodilator FEV 1 ≤ 30% of predicted) associated with chronic bronchitis; mean age of 64 years, 69% male, and 80% Caucasian. The use of long-acting muscarinic antagonists was allowed. Effect on Exacerbations The effect of DALIRESP 500 mcg once daily on COPD exacerbations was evaluated in five 1-year trials (Trials 3, 4, 5, 6 and 9).

Two of the trials (Trials 3 and 4) conducted initially enrolled a population of patients with severe COPD (FEV 1 ≤50% of predicted) inclusive of those with chronic bronchitis and/or emphysema who had a history of smoking of at least 10 pack years. Inhaled corticosteroids were allowed as concomitant medications and used in 61% of both DALIRESP and placebo-treated patients and short-acting beta agonists were allowed as rescue therapy. The use of long-acting beta agonists, long-acting anti-muscarinics, and theophylline were prohibited.

The rate of moderate or severe COPD exacerbations was a co-primary endpoint in both trials. There was not a symptomatic definition of exacerbation in these 2 trials. Exacerbations were defined in te… [Excerpted — this section continues on DailyMed.]

13 NONCLINICAL TOXICOLOGY

13.1Carcinogenesis, Mutagenesis, Impairment of Fertility Long-term studies were conducted in hamsters and mice with roflumilast to evaluate its carcinogenic potential. In 2-year oral gavage carcinogenicity studies, roflumilast treatment resulted in dose-related, statistically significant increases in the incidence of undifferentiated carcinomas of nasal epithelium in hamsters at ≥8 mg/kg/day (approximately 11 times the MRHD based on summed AUCs of roflumilast and its metabolites). The tumorigenicity of roflumilast appears to be attributed to a reactive metabolite of 4-amino-3,5-dichloro-pyridine N-oxide (ADCP N-oxide).

No evidence of tumorigenicity was observed in mice at roflumilast oral doses up to 12 and 18 mg/kg/day in females and males, respectively (approximately 10 and 15 times the MRHD, respectively, based on summed AUCs of roflumilast and its metabolites). Roflumilast tested positive in an in vivo mouse micronucleus test, but negative in the following assays: Ames test for bacterial gene mutation, in vitro chromosome aberration assay in human lymphocytes, in vitro HPRT test with V79 cells, an in vitro micronucleus test with V79 cells, DNA adduct formation assay in rat nasal mucosa, liver and testes, and in vivo mouse bone marrow chromosome aberration assay.

Roflumilast N-oxide was negative in the Ames test and in vitro micronucleus test with V79 cells. In a human spermatogenesis study, roflumilast 500 mcg had no effects on semen parameters or reproductive hormones during the 3-month treatment period and the following 3-month off-treatment period. In a fertility study, roflumilast decreased fertility rates in male rats at 1.8 mg/kg/day (approximately 29 times the MRHD on a mg/m 2 basis).

The male rats also showed increases in the incidence of tubular atrophy, degeneration in the testis and spermiogenic granuloma in the epididymides. No effect on rat fertility rate or male reproductive organ morphology was observed at 0.6 mg/kg/day (approximately 10 times the MRHD on a mg/m 2 basis). In a female fertility study, no effect on fertility was observed up to the highest roflumilast dose of 1.5 mg/kg/day in rats (approximately 24 times the MRHD on a mg/m 2 basis).

13.1Carcinogenesis, Mutagenesis, Impairment of Fertility Long-term studies were conducted in hamsters and mice with roflumilast to evaluate its carcinogenic potential. In 2-year oral gavage carcinogenicity studies, roflumilast treatment resulted in dose-related, statistically significant increases in the incidence of undifferentiated carcinomas of nasal epithelium in hamsters at ≥8 mg/kg/day (approximately 11 times the MRHD based on summed AUCs of roflumilast and its metabolites).

Medicaid utilization & spend

📍 This exact package only: Medicaid data is reported per full 11-digit NDC — labeler, product and pack size — so every number here is for this package alone, not the drug overall. Other pack sizes report separately.
💊 Pharmacy benefit only: These are Medicaid outpatient pharmacy claims, billed by NDC. They exclude the medical benefit — clinic- or hospital-administered drugs billed under HCPCS J-codes — so drugs used mostly that way (e.g. Avastin, Lucentis, Keytruda) can look low or missing here. That’s expected, not an error.

Medicare Part D spend CMS · PART D · 2026 (Q1)

Medicare Part D (outpatient prescription) spending for Daliresp — the program that covers self-administered drugs. 1 manufacturer.
⚠️ Drug-level data: CMS publishes Part D spending by drug, not by NDC — these figures combine every manufacturer, strength and package size sold under the name Daliresp. That’s a different level of aggregation than the Medicaid card above, which is specific to this exact 11-digit NDC (pack size included), so the two aren’t directly comparable.
