Apremilast in psoriatic arthritis
1Department of Internal Medicine 3, University of Erlangen-Nuremberg Erlangen, Germany. georg.schett@uk-erlangen.de.
Apremilast effectively treats psoriatic arthritis and skin disease by inhibiting phosphodiesterase 4 (PDE4). This mechanism increases cAMP levels, reducing inflammatory cytokines and improving patient outcomes.
Area of Science:
- Immunology
- Pharmacology
- Dermatology
Background:
- Psoriatic arthritis (PsA) is a chronic inflammatory condition affecting joints and skin.
- Current treatments aim to manage inflammation and improve patient quality of life.
Purpose of the Study:
- To summarize the efficacy and safety of apremilast for treating psoriatic arthritis.
- To elucidate the mechanism of action of apremilast in PsA.
Main Methods:
- Review of four phase III clinical trials.
- Pharmacological analysis of apremilast's mechanism.
Main Results:
- Apremilast demonstrated efficacy and safety in moderate to severe PsA.
- The drug is approved in the US and Europe for PsA treatment.
- Apremilast also shows benefits for psoriatic skin disease.
Conclusions:
- Apremilast is a valuable therapeutic option for PsA.
- Its mechanism involves PDE4 inhibition, leading to increased cAMP and reduced pro-inflammatory cytokines.
- This results in clinical improvement for patients with PsA and psoriatic skin disease.

Antiasthma Drugs: Leukotriene Modifiers
Leukotriene modifiers work through two distinct mechanisms:
Treatment for Pulmonary Arterial Hypertension: Prostacyclin Receptor Agonists
These agonists bind to the IPR receptor situated on the plasma membrane of the pulmonary artery smooth muscle cells. This binding triggers a cascade of reactions known as the GS-AC-cAMP-PKA pathway. This pathway results in the relaxation of smooth muscle...
Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...
Antiasthma Drugs: Inhaled Corticosteroids and Glucocorticoids
ICS work through a multifaceted mechanism of action. They suppress the inflammatory response caused by the proliferation of TH cells. They also reduce the transcription of the IL-2 gene, which is involved in the...
Asthma: Pathogenesis and Management
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
