If It's Dry, Wet It; If It's Wet,
Dry It: A Commonsense Guide
to Dermatologic Therapy

Pharmacologic management of dermatologic conditions isn’t
really that simple. This presentation well review classes of
dermatologic pharmacology, including not only emollients,
drying agents, and steroids, but also other treatments such as
antibiotics, antifungal agents, antivirals, chemotherapeutic
agents, immunomodulators, and other treatments for
common cutaneous conditions. Learn what to use and what
complications might develop.
• Review standard treatment regimens for common skin • Discuss recent advances in treatment of common • List common pharmaceutical agents used in therapy of • Identify patients in need of referral to a dermatologist.

Catherine A. Marco, MD, FACEP
Professor, Department of Surgery, Division of Emergency Medicine University of Toledo College of Medicine Review standard treatment regimens for common skin conditions. Discuss recent advances in treatment of common cutaneous conditions. List common pharmaceutical agents used in therapy of cutaneous conditions. Identify patients in need of dermatologic referral or consultation.
Skin diseases constitute a significant fraction of health care economics in the United
States. Cutaneous complaints result in approximately 10% of outpatient medical visits
and $36 billion in health care annually, including $20 billion in ambulatory care costs and
$3 billion in prescription costs, and $2 billion in indirect costs (lost work days, etc.).
Rapidly advancing diagnostic and therapeutic technologies result in novel dermatologic
agents, and novel uses of traditional agents.
Is there truth to the old adage: “ If It’s Dry, Wet It; If It’s Wet, Dry It; Otherwise, Use
Steroids” ??? Indeed, there is some truth to the ancient advice that selection of vehicle
and formulation are important, and that steroids are frequently therapeutic for
inflammatory skin conditions. In addition to a review of vehicles, formulations, and
steroids, this lecture will address other commonly prescribed systemic and topical
medications used to treat dermatologic disorders.
There is an overwhelming amount of literature on the subject of skin therapies (66,411
published articles in the past 10 years!). This presentation will highlight a select group
of therapies for dermatologic complaints seen in emergency medicine. Continuing
medical education about new therapies represents an essential component of the effective
delivery of quality medical care. Dermatologic consultation should be sought when
appropriate. Pharmaceutical references should be used to assist in prescribing
appropriate dosages and routes of administration.
Systemic Topical Mucosal
Intralesional agents
Case 1:
A 35 year old man with longstanding psoriasis presents with an exacerbation of symptoms. He requests
“that new foam – it’s better than the cream, isn’t it?”


mineral oil, baby oil (Eucerin, Aquaphor, “moisturizers” (primarily water, fragrances) Retard water loss, occlude the treatment molecules, increase skin Ointments, creams and gels: emulsions of oil in water Increase even distribution and absorption Emulsifying
Create oil-in-water preparations (creams, lotions) Humectants
maintain appropriate water content for oil-in-water preparations; increase Emulsion stabilizers and viscosity builders
Increase potency by increasing absorption Preservatives and chemical stabilizers
Alcohols, parabens, propylene glycol, etc. CHOICE OF PREPARATION:
