Medication Summary
The goals of pharmacotherapy are to reduce inflammation and eliminate infection, if present.
Corticosteroids
Class Summary
These agents are used for their anti-inflammatory properties, but they must be used with caution because they have local and systemic side effects.
Topical corticosteroids may be used alone or in combination retinoic acid.
Triamcinolone (Kenalog, Amcort)
For inflammatory reactions responsive to steroids; decreases inflammation by suppressing migration of PMN leukocytes and reversing capillary permeability.
Prednisone (Deltasone, Meticorten, Orasone)
May decrease inflammation by reversing increased capillary permeability and suppressing PMN activity. Used when patient has acute flare.
Clobetasol propionate (Olux)
Available as a 0.05% foam (Olux).
Fluocinonide (Lidex) or Mometasone furoate (Elocon)
Class 2 steroid (potent). Fluocinonide available as a 0.05% cream, ointment, and gel, and mometasone furoate available as 0.1% ointment.
Retinoids
Class Summary
Although the exact mechanism of action is unknown, retinoids decrease the cohesiveness of abnormal hyperproliferative keratinocytes, modulate keratinocyte differentiation, and have anti-inflammatory properties.
Isotretinoin (Accutane)
Oral agent that treats serious dermatologic conditions. Synthetic 13-cis isomer of the naturally occurring tretinoin (trans -retinoic acid). Both agents are structurally related to vitamin A.
Decreases sebaceous gland size and sebum production. May inhibit sebaceous gland differentiation and abnormal keratinization.
A US Food and Drug Administration–mandated registry is now in place for all individuals prescribing, dispensing, or taking isotretinoin. For more information on this registry, see iPLEDGE. This registry aims to further decrease the risk of pregnancy and other unwanted and potentially dangerous adverse effects during a course of isotretinoin therapy.
Tretinoin topical (Retin-A)
Although exact mechanism of action is unknown, retinoids decrease cohesiveness of abnormal hyperproliferative keratinocytes, modulate keratinocyte differentiation, and have anti-inflammatory properties.
Available as 0.025%, 0.05%, and 0.1% creams. Also available as 0.01% and 0.025% gels.
Antibiotics
Class Summary
Empiric antimicrobial therapy must be comprehensive and should cover all likely pathogens in the context of this clinical setting.
Erythromycin base (E-Mycin, Erythrocin)
Inhibits bacterial growth, possibly by blocking dissociation of peptidyl t-RNA from ribosomes, causing RNA-dependent protein synthesis to arrest. For treatment of staphylococcal and streptococcal infections. Age, weight, and severity of infection determine proper dosage in children. When twice-daily dosing is desired, half total daily dose may be taken q12h. Double the dose for more severe infections.
Mupirocin (Bactroban)
Topical antibiotic; inhibits bacterial growth by inhibiting RNA and protein synthesis.
Doxycycline (Vibramycin)
Broad-spectrum, synthetically derived bacteriostatic antibiotic in the tetracycline class. Almost completely absorbed, concentrates in bile, and is excreted in urine and feces as a biologically active metabolite in high concentrations.
Inhibits protein synthesis and, thus, bacterial growth by binding to 30S and possibly 50S ribosomal subunits of susceptible bacteria. May block dissociation of peptidyl t-RNA from ribosomes, causing RNA-dependent protein synthesis to arrest.
Rifampin (Rifadin, Rimactane)
Inhibits RNA synthesis in bacteria by binding to beta-subunit of DNA-dependent RNA polymerase, which, in turn, blocks RNA transcription.
