Desoximetasone

Allopathic
Indications

A. Approved Indications

  • Inflammatory and Pruritic Dermatoses Responsive to Corticosteroids, including:
    • Psoriasis (except severe plaque psoriasis over large body areas)
    • Atopic dermatitis
    • Contact dermatitis (allergic or irritant)
    • Seborrheic dermatitis
    • Nummular eczema
    • Lichen simplex chronicus
    • Lichen planus
    • Discoid lupus erythematosus

B. Clinically Accepted Off-Label Uses

  • Hypertrophic scars and keloids (in selected cases, applied topically or via intralesional injection off-label)
  • Lichen sclerosus (when other corticosteroids are not effective or tolerated)
  • Treatment-resistant dermatoses requiring a high-potency corticosteroid, under dermatologist supervision
Dosage & Administration

A. Adults

  • Desoximetasone 0.05% or 0.25% formulations:
    • Apply a thin layer to the affected area twice daily, gently rubbed in until fully absorbed.
    • For high-potency 0.25% products, limit to short-term use (2–4 weeks) on non-facial, thickened skin areas.
    • Occlusion may be used for refractory lesions but increases risk of systemic absorption.

B. Pediatric Use

  • Use with caution in children >2 years.
  • Use lower potency (0.05%) and short durations only.
  • Avoid high-potency (0.25%) use unless directed by a specialist due to risk of HPA axis suppression.

C. Elderly

  • Same dosage as adults, but monitor more closely due to increased skin fragility and risk of atrophy.

D. Special Populations

  • Renal/Hepatic Impairment: No dose adjustments required for topical use; avoid large surface area applications or occlusion which may increase systemic absorption.

Route of Administration: Topical

Duration of Use:

  • Limit continuous use to no more than 2 weeks on face, groin, or underarms.
  • Longer durations may be acceptable for thick, lichenified plaques under specialist guidance.
Mechanism of Action (MOA)

Desoximetasone is a synthetic fluorinated corticosteroid with high anti-inflammatory, antipruritic, and vasoconstrictive properties. It penetrates the skin and binds to intracellular glucocorticoid receptors, altering gene transcription in target cells. This results in inhibition of pro-inflammatory cytokines, prostaglandins, leukotrienes, and histamine, and increases the production of lipocortins, which suppress phospholipase A2 activity. These mechanisms reduce redness, swelling, and itching associated with dermatologic inflammation.

Pharmacokinetics
  • Absorption: Topical absorption depends on condition of skin, area treated, duration of use, and whether occlusive dressings are applied.
    • Absorption is significantly enhanced through damaged or thin skin.
  • Distribution: Systemic distribution is minimal under normal use, but drug may circulate bound to plasma proteins if absorbed.
  • Metabolism: Once absorbed, hepatic metabolism follows similar pathways as endogenous corticosteroids.
  • Excretion: Eliminated primarily in urine as inactive metabolites.
  • Half-life: Not well defined due to minimal systemic absorption in most patients.
Pregnancy Category & Lactation
  • Pregnancy:
    • No FDA pregnancy letter assigned under new guidelines.
    • Use only if benefits outweigh potential risks; prolonged or extensive use should be avoided, particularly with occlusion or on large surface areas.
  • Lactation:
    • Unknown if desoximetasone is excreted in human milk.
    • Low systemic absorption makes it unlikely to harm a breastfeeding infant when used topically.
    • Avoid application to the breast area, especially near the nipple.
Therapeutic Class
  • Primary Class: Corticosteroid
  • Subclass: High-potency topical corticosteroid
  • Potency Group: Group II or III (depending on strength and formulation)
Contraindications
  • Known hypersensitivity to desoximetasone or any excipients
  • Untreated skin infections (bacterial, fungal, viral)
  • Rosacea or perioral dermatitis
  • Application to ocular or periocular areas (risk of glaucoma or cataracts)
  • Skin ulcerations or open wounds
Warnings & Precautions
  • Systemic absorption risk: Greater when used under occlusion, on large areas, for prolonged periods, or in pediatric patients.
  • Adrenal suppression: May occur, especially with high-potency forms or in children.
  • Skin atrophy, striae, telangiectasia: Risk increases with prolonged use.
  • Delayed wound healing: Topical corticosteroids may impair wound repair.
  • Ophthalmic risk: Avoid application near eyes; may increase intraocular pressure and cause glaucoma or cataracts.
  • Secondary infections: Steroid use may mask or exacerbate bacterial, fungal, or viral infections.
Side Effects

Common (≥1%):

  • Skin reactions: Burning, stinging, itching, dryness, irritation
  • Epidermal changes: Skin thinning, atrophy, telangiectasia, hypopigmentation

Less Common (0.1–1%):

  • Folliculitis
  • Acneiform eruptions
  • Contact dermatitis

Rare (<0.1%) or Serious:

  • HPA axis suppression (especially in children or with prolonged high-potency use)
  • Hyperglycemia or glycosuria (from systemic corticosteroid absorption)
  • Secondary skin infections
  • Ocular complications (glaucoma, cataract if applied near eyes)
Drug Interactions
  • Drug-Drug:
    • Minimal systemic interaction due to topical application.
    • Potential for additive systemic corticosteroid effects if combined with oral or inhaled corticosteroids.
  • Drug-Food/Alcohol:
    • No significant interactions.
  • Enzyme Systems:
    • If absorbed systemically, metabolism is via hepatic CYP enzymes, though not clinically significant in standard topical use.
Recent Updates or Guidelines
  • Recent dermatology guidelines (AAD 2023) continue to classify desoximetasone 0.25% as a high-potency corticosteroid suitable for short-term management of thick plaques in psoriasis or chronic eczema.
  • Increased caution emphasized in pediatric and elderly populations due to skin barrier sensitivity.
  • New formulation availability (e.g., foam or gel) under review to enhance delivery in hair-bearing areas.
Storage Conditions
  • Temperature: Store at 20°C to 25°C (68°F to 77°F)
  • Humidity: Store in dry conditions
  • Light Protection: Protect from direct light; keep in original packaging
  • Handling Instructions:
    • Do not freeze
    • Keep out of reach of children
    • Avoid contamination of the container tip or tube nozzle
    • Replace cap tightly after each use
