Cards

Term
decrease binding forces within the horny layer, enhances desquamation and eliminates scaling
Definition
Emollients (ex: Lubriderm)
Term
disrupt coenocyte to coenocyte cohesion in the abnormal horny layer
Definition
Keratolytic (salicylic acid)
Term
salts reduce activated T cells in skin
Definition
Balneotherapy
Term
modulates keratinocyte proliferation and differentiation
Definition
Tazarotene
Term
not completely understood, inhibits phospholipase A and reduction arachadonic acid, prostaglandins, leukotrienes
Definition
Topical corticosteroids
Term
not well understood, down regulation of epidermal proliferation leading to reduction in plaque elevation, stimulate transient epidermal hyperplasia, follow by cytostatic effect with epidermal thinning
Definition
Coal Tar
Term
antiproliferative activity on human keratinocytes inhibiting DNA synthesis and inhibition of transcription inflammatory cytokines
Definition
Anthralin
Term
inhibits keratinocyte differentiation and proliferation and provides anti-inflammatory benefit by shifting to an increase in T helper cells type 2 cytokine decrease IL 1,6,8 and decrease interferon gamma
Definition
Vitamin D analogues
Term
unclear, proposed effects include: inhibition of neutrophil migration, reduction in epidermal concentration of polyamines
Definition
Oral Retinoids
Term
inhibits 1st phase of T cell activation
Definition
Cyclosporine
Term
Inhibits t cell activation and only used for severe psoriasis
Definition
Tacrolimus
Term
acts as a competitive inhibitor of dihydrolate reductase subsequently inhibiting DNA and RNA synthesis because tetrahydrofolate is responsible in helping with synthesis of nucelotides, which inhibits replication and function of B and T cells which inhibit epidermal cell division
Definition
Methotrexate
Term
anti-inflammatory activity by inhibiting 5-lipoxygenase
Definition
Sulfasalazine
Term
inactivates ribonucleotide reductase; inhibiting cell wall synthesis in S phase
Definition
Hydroxyurea
Term
immunomodulator, anti-proliferative, anti-inflammatory, immunosuppressie effects
Definition
Phototherapy
Term
chimeric monoclonal antibody directed against TNF alpha
Definition
Infliximab
Term
blocks TNF alpha, fusion protein and fully humanized (less risk of antibody development)
Definition
Etanercept
Term
human IgG1 monoclonal TNF alpha antibody, inactivates TNF alpha by binding to it
Definition
Adalimumab
Term
dimeric fusion protein nad inhibits T-cell activation and proliferation (inactivation of T cells)
Definition
Alefacept
