Overview

Roflumilast is a phosphodiesterase (PDE) type 4 inhibitor.

Roflumilast and its active metabolite, roflumilast N-oxide, are inhibitors of PDE4. Inhibition of PDE4 (a major cyclic 3',5'-adenosine monophosphate (cyclic AMP) metabolizing enzyme) activity by roflumilast and roflumilast N-oxide leads to the accumulation of intracellular cyclic AMP. The specific mechanism(s) by which roflumilast exerts its therapeutic action are not well defined.

After application of roflumilast cream, the plasma concentration versus time profile was relatively flat, with a peak-to-trough ratio <2. The pharmacokinetics of roflumilast cream have been evaluated in adult and pediatric patients with plaque psoriasis or atopic dermatitis and the pharmacokinetics of roflumilast foam have been investigated in adult and pediatric patients with seborrheic dermatitis or plaque psoriasis of the scalp and body. The plasma protein binding of roflumilast and the roflumilast N-oxide metabolite is approximately 99% and 97%, respectively.

Following oral administration, roflumilast and the N-oxide metabolite account for 87.5% of the total dose administered in plasma. Roflumilast is not detectable in urine, and the roflumilast N-oxide metabolite is detectable in trace amounts (less than 1%); other conjugated metabolites are detectable in urine. While roflumilast is 3 times more potent than the roflumilast N-oxide metabolite at inhibition of the PDE4 enzyme in vitro, the plasma AUC of the roflumilast N-oxide metabolite is approximately 7-8-fold greater than the plasma AUC of roflumilast following topical administration.

Following topical administration, the half-lives of roflumilast and the roflumilast N-oxide metabolite are 4 and 4.6 days, respectively. No clinically significant differences in pharmacokinetics of roflumilast or roflumilast N-oxide metabolite observed based on age, sex, race, or ethnicity.

USES: This medication is used to treat a certain skin condition (plaque psoriasis). Roflumilast may help to reduce the redness, thickening, and scaling of the skin that occurs with this condition.

Indications

The following indications are listed for Zoryve:

  • Plaque Psoriasis

Dosing

Roflumilast 0.05% and 0.15% cream is for the treatment of mild to moderate atopic dermatitis and 0.3% cream is for the treatment of plaque psoriasis.

Drug interactions

Roflumilast is extensively metabolized via Phase 1 cytochrome P450 (CYP) enzyme and Phase II conjugation reactions. In vitro, studies suggest roflumilast metabolism is mediated by CYP1A2 and CYP3A4 enzymes. The N-oxide metabolite of roflumilast is the only major metabolite observed in human plasma. Therapeutic plasma concentrations of roflumilast and its N-oxide metabolite do not inhibit CYP1A2, 2A6, 2B6, 2C8, 2C9, 2C19, 2D6, 2E1, 3A4/5, or 4A9/11; therefore, interactions with these enzymes are unlikely. In vitro, studies have demonstrated no induction of CYP1A2, 2A6, 2C9, 2C19, or 3A4/5, and only weak induction of CYP2B6 by roflumilast.

No formal drug interaction studies have been conducted with topical roflumilast.

Contraindications

*Moderate to severe liver impairment (Child-Pugh B or C).

Adverse reactions

The most common adverse reactions (>=1%) in patients administered roflumilast cream for plaque psoriasis include diarrhea, headache, insomnia, nausea, application site pain, upper respiratory tract infections, and urinary tract infections.

The most common adverse reactions (>=1%) in patients administered roflumilast cream for atopic dermatitis include headache, nausea, application site pain, diarrhea, and vomiting.

The most common adverse reactions (>=1%) in patients administered roflumilast foam for seborrheic dermatitis include nasopharyngitis, nausea, and headache.

The most common adverse reactions (>=1%) in patients administered roflumilast foam for plaque psoriasis of the scalp and body include headache, diarrhea, nausea, and nasopharyngitis.
