Medication Summary
The goals of pharmacotherapy are to reduce morbidity and to prevent complications.
Retinoids
Class Summary
These agents modulate keratinocyte differentiation and decrease sebum production.
Isotretinoin (Accutane)
Oral agent that treats serious dermatologic conditions, isotretinoin is synthetic 13-cis isomer of naturally occurring tretinoin (trans -retinoic acid). Both agents are structurally related to beta-carotene. 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.
Female patients must sign an informed consent that they will use contraceptives during treatment course and for 30 d after discontinuing therapy.
Antibiotics
Class Summary
Empiric antimicrobial therapy must be comprehensive and should cover all likely pathogens in the context of the clinical setting. Antibiotic selection should be guided by blood culture sensitivity whenever feasible.
Ampicillin (Principen, Omnipen, Marcillin)
Bactericidal activity against susceptible organisms. Alternative to amoxicillin when unable to take medication orally.
Trimethoprim and sulfamethoxazole (Bactrim, Septra)
Inhibits bacterial growth by inhibiting synthesis of dihydrofolic acid.
