HardRoflumilastSevere COPD with chronic bronchitis and frequent exacerbationsSCE Respiratory

A 67-year-old woman is reviewed in a specialist COPD clinic. She has chronic productive cough and post-bronchodilator FEV1 42% predicted. During the previous 12 months she has had three COPD exacerbations requiring prednisolone and antibiotics, including one hospital admission, despite verified adherence to LAMA/LABA/ICS therapy, satisfactory inhaler technique, smoking cessation and pulmonary rehabilitation. She weighs 52 kg with a stable BMI of 18.1 kg/m². Her eGFR is 24 mL/min/1.73 m². Liver biochemistry and synthetic function are normal. Ten years ago she had a depressive episode without suicidal ideation or behaviour; she has been asymptomatic without antidepressant treatment for 8 years. She has no current mood disturbance and understands the need to report neuropsychiatric symptoms. After discussion of benefits and adverse effects, she wishes to proceed with roflumilast. Which roflumilast prescribing plan is most appropriate?

Correct answer: DInitiate 250 micrograms once daily for 28 days, then 500 micrograms once daily, with weight and mood monitoring

She meets the NICE criteria for specialist-initiated roflumilast: severe COPD with chronic bronchitis, post-bronchodilator FEV1 below 50% predicted, and at least two exacerbations in 12 months despite LAMA/LABA/ICS therapy. The recommended initiation regimen is 250 micrograms once daily for 28 days, followed by the therapeutic maintenance dose of 500 micrograms once daily. The introductory dose reduces early adverse effects and treatment discontinuation but is subtherapeutic and should not be continued as maintenance. Her severe renal impairment does not require dose adjustment and is not a contraindication. Low body weight is also not an absolute contraindication, although weight should be checked at each visit in an underweight patient; treatment should be stopped if unexplained clinically concerning weight loss develops. Patients below 60 kg also have an increased risk of sleep disturbance. A remote depressive episode without suicidal ideation or behaviour does not automatically preclude treatment. It requires an individualised benefit–risk assessment and counselling to report mood or behavioural changes. Roflumilast is not recommended when depression has been associated with suicidal ideation or behaviour, and it should be discontinued if new or worsening psychiatric symptoms or suicidality emerge. Starting 500 micrograms immediately omits the recommended tolerability lead-in, whereas indefinite 250-microgram treatment is unlikely to provide adequate PDE4 inhibition.
