Highly liphophilic and keratophilic
Also used to treat Cushing’s syndrome and prostate cancer
______ (for psoriasis) is also Category X
Broad spectrum-IV (systemic infection) or topical use (lotion/cream/lozenges)
Active to many Gram(+) bacteria. Inhibit bacterial protein synthesis. Useful for treatment of impetigo caused by Staph aureus.
MOA: Inhibit squalene epoxidase
A fusion protein (TNFR-2 fused with IgG Fc). MOA: Binds to and inhibit TNF-alpha
Nucleoside (guanosine) analogs. Activated by phosphorylations (Viral Thymidine Kinase and host kinases). Inhibit viral DNA polymerase and cause chain termination. Treat HSV-1, HSV-
Use: Treat atopic dermatitis (a type of eczema)
Used to treat vulvovaginal candidiasis
Inhibit cytochrome P450 14 alpha-demethylase (P45014DM) involved in the biosynthesis of ergosterol
Side Effects: Life-threatening liver toxicity, nausea, vomiting, gynecomastia
Side effects: Burning sensation, potential risk of malignancy on skin and lymph nodes
Use: Treat external genital and perianal warts, keratoses, primary basal cell carcinomas
_______ is photochemically stable and less irritating
Acne Medication: Not recommended during pregnancy or breast-feeding (potentially carcinogenic)
Acne Medication: Competitive Inhibitor of PABA
Major Side Effects: IV - chills, fever, renal toxicity.
A fusion protein of CD2 binding domain of LFA-3 and IgG Fc.
MOA: Calcineurin inhibitors (Inhibit T cell activation and prevent the release of inflammatory cytokines)
1st Generation Retinoic Acid Derivatives
Protein synthesis inhibitor (aminoglycoside). Active against Gram (-) bacteria
Narrow spectrum- only topical use (lozenges/ suspension/cream) for treating cutaneous or mucosal candidiasis
Acne Preparation: Pregnancy Category X
The drug of choice for chronic infections caused by dermatophytes (used for months)

3rd Generation Retinoid Acid Derivatives
Active against Gram(-) bacteria (target LPS)
A p450 inducer and substrate
Name a drug that increases clearance of azoles.
MOA: Acts on Toll-like receptor TLR7 (Stimulate release of IFN-alpha, TNF-α and interleukins)
Cell wall synthesis inhibitor. Gram (+) only
Acne Medication: Protein synthesis inhibitor. Active against anaerobes.
Retinoic Acid Side Effects
May reverse back to etretinate which is more toxic & has a longer t1/2
Lipid formulations are less toxic
MOA: Bind to CD2, blocking CD2/LFA3 interaction, leading to inhibition of T cell activation
