Medication Summary
The goals of pharmacotherapy are to reduce morbidity and to prevent complications.
Antifungals
Class Summary
Mechanism of action may involve alteration of RNA and DNA metabolism or an intracellular accumulation of peroxide that is toxic to fungal cells.
Ketoconazole topical
Available as ketoconazole cream 2% (Nizoral), ketoconazole foam (Extina), ketoconazole shampoo 2% (Nizoral 2%; prescription only in United States), ketoconazole shampoo 1% (Nizoral A-D Shampoo; over-the-counter in United States)
Imidazole broad-spectrum antifungal agent. Inhibits synthesis of ergosterol, causing cellular components to leak, resulting in fungal cell death.
Corticosteroids
Class Summary
Have anti-inflammatory properties and cause profound and varied metabolic effects. Also modify body's immune response to diverse stimuli.
Betamethasone topical (Valisone)
Medium-strength topical corticosteroid for body areas. Decreases inflammation by suppressing migration of polymorphonuclear leukocytes and reversing capillary permeability. Affects production of lymphokines and has inhibitory effect on Langerhans cells.
Desonide
For inflammatory dermatosis responsive to steroids. Decreases inflammation by suppressing migration of polymorphonuclear leukocytes and reversing capillary permeability.
Keratolytics
Class Summary
Cause cornified epithelium to swell, soften, macerate, and then desquamate.
Coal tar shampoo (DHS Tar, MG217, Theraplex T, Psoriasin); Scytera foam
Inhibits deregulated epidermal proliferation and dermal infiltration; antipruritic and antibacterial.
Immunosuppressants
Class Summary
Exert anti-inflammatory affect by inhibiting T-lymphocyte activation. Safer than topical steroids for prolonged use or in skin folds.
Tacrolimus ointment (Protopic)
Nonsteroidal anti-inflammatory agent. Should not cause steroid-type skin atrophy. Currently indicated only for atopic dermatitis in immunocompetent patients ≥ 2 y.
Pimecrolimus (Elidel cream 1%)
Nonsteroidal anti-inflammatory agent. Should not cause steroid-type skin atrophy. Currently indicated only for atopic dermatitis in immunocompetent patients ≥ 2 y. Use cream sparingly to avoid maceration in skin folds.
