罗氟司特乳膏治疗银屑病的详细疗效介绍

Introduction: Roflumilast cream, a phosphodiesterase 4 (PDE4) inhibitor that has shown significant efficacy in the treatment of psoriasis, provides an effective alternative to topical corticosteroids with comparable efficacy to corticosteroids but with a higher safety profile. It is widely used to treat a variety of skin diseases, such as psoriasis and atopic dermatitis. Roflumilast cream can effectively improve the thickness, scale and erythema of the lesion area, and also has a positive effect on joint psoriasis.

Efficacy of Roflumilast Cream

Roflumilast Cream has been shown to be safe and effective in improving disease clearance in hard-to-treat areas such as knees and elbows, as well as in sensitive areas such as the face, genitals, and intertriginous areas. Roflumilast cream can be used without time limit and can relieve patients' itching symptoms and improve their skin condition.

Efficacy of Roflumilast Cream Clinical Trial

In a clinical phase 2b double-blind trial, the research team recruited 331 adults with plaque psoriasis. Participants were randomly assigned to three groups: 0.3% roflumilast cream, 0.15% roflumilast cream, or placebo, to be used once daily for 12 weeks. The primary efficacy outcome was investigator global assessment (IGA) of disease eradication or nearly eradication status at week 6.

In the 0.3% roflumilast group: 28% of patients had an IGA score indicating that psoriasis was eradicated or nearly eradicated at week 6, compared with 8% in the placebo group. 0.15% roflumilast group: 23% of patients achieved the same efficacy. Placebo group: 8% of patients had disease eradicated or nearly eradicated. For patients with at least mildly severe joint psoriasis at baseline, 73% of patients in the 0.3% roflumilast group showed eradication or near eradication of disease at week 6 IGA score and at least a 2-grade improvement in the interarticular area IGA score.

The mechanism of action of roflumilast cream

As a non-hormonal phosphodiesterase-4 (PDE4) inhibitor, it reduces the degradation of intracellular cAMP by inhibiting the activity of PDE4, thereby increasing the level of intracellular cAMP. As an important intracellular signaling molecule, cAMP is involved in the regulation of various cell functions, including anti-inflammation, anti-proliferation, immune regulation, etc. Roflumilast cream can exert anti-inflammatory effects and reduce the symptoms of psoriasis.

Side effects of roflumilast cream

Roflumilast cream may also cause some side effects, including skin irritation, erythema, itching, burning sensation, pain, etc., as well as photosensitivity reactions, which means the skin becomes more sensitive to ultraviolet rays after use. If allergic reactions such as skin redness, itching or other discomfort occur during use, you should stop using it immediately and wash the allergic area with clean water. People with severe allergies should stop using it immediately and go to the hospital for treatment. When using roflumilast cream, patients need to follow the doctor's advice and pay attention to observe the body's reaction. If there are any abnormalities, they should seek medical treatment in time.

Although roflumilast cream has shown promising efficacy in both short- and long-term trials, each patient's response may vary. Specific treatment plans and medication guidance should be formulated and adjusted by doctors based on the specific conditions of the patient. Professional medical advice should be sought before using any medication.
