In our article on Slynd (Med Lett Drugs Ther 2020; 62:18), the drospirenone-only oral contraceptive, we mentioned that drospirenone has antiandrogenic activity that could improve acne and antimineralocorticoid activity that could cause hyperkalemia. We should have added that concurrent use of drospirenone with other drugs that increase potassium levels, such as the anti-androgen aldosterone receptor antagonist spironolactone (Aldactone, and generics), which is often used off-label for treatment of acne, can increase the risk of hyperkalemia.

Intrauterine devices (IUDs) and the etonogestrel implant are the most effective reversible contraceptive methods available.

When used alone, barrier and fertility-based methods generally have higher failure rates than other methods.

Differin Gel 0.1% (Galderma), a topical formulation of the retinoid adapalene, will soon be available over the counter (OTC) for once-daily treatment of acne in patients ≥12 years old. It is the first topical retinoid to be approved for sale over the counter.

All topical retinoids normalize keratinization and appear to have anti-inflammatory effects; whether any one topical retinoid is more effective than any other is not clear. Many dermatologists now recommend topical retinoids for first-line treatment of acne; they can be used alone or in combination with antibiotics to treat both inflamed and noninflamed acne lesions, or for maintenance treatment. Retinoid/antimicrobial combinations are more effective than either component alone, particularly for patients with inflammatory lesions.1

Adverse effects of topical retinoids include dry skin, scaling, photosensitivity, erythema, burning, and pruritus. Although only small amounts of the drug are absorbed systemically following topical application, adapalene is classified as category C (teratogenic in rats; no adequate studies in pregnant women) for use during pregnancy.

Adapalene (Differin, and generics) is available by prescription in 0.1% gel, cream, and lotion formulations and in a 0.3% gel formulation. It is also available by prescription in combination with the oxidizing agent benzoyl peroxide (Epiduo; Epiduo Forte).

The cost of one 45-gram tube ranges from about $157 for generic adapalene to $580 for Differin.2 The cost of OTC Differin Gel 0.1% was not available at the time of publication.

Addendum: Depression and Suicidality with Isotretinoin

Our article earlier this year on Drugs for Acne1 stated that the oral retinoid isotretinoin (Accutane, and others) is the most effective drug available for patients with severe nodulocystic acne, but warned that depression, suicidality, myalgia, hypertriglyceridemia, and other adverse effects can occur. One of our readers objected to our listing depression and suicidality, which are the subject of a prominent warning in the package insert, in the same sentence as indisputable side effects such as hyperlipidemia and myalgia.

Depression and suicidal ideation have been reported in patients with severe acne after starting treatment with isotretinoin, including some cases in which symptoms resolved after discontinuation of the drug and reappeared after rechallenge.2 A cause-and-effect relationship has not been established, however, and acne itself is associated with symptoms of anxiety and depression.

Two large population-based cohort studies conducted in Canada and the UK found no evidence that treatment of acne with isotretinoin was associated with an increased risk of depression, suicide, or other psychiatric adverse effects.3 In a small US cohort study in 132 patients 12-19 years old with moderate to severe acne, use of isotretinoin did not increase depressive symptoms compared to use of topical drugs and oral antibiotics, and treatment of acne appeared to decrease symptoms of depression.4 A prospective, observational study in 346 patients ≥16 years old with moderate acne found that treatment with isotretinoin for 30 weeks reduced symptoms of anxiety and depression.5 Other studies have reached similar conclusions.

The pathogenesis of acne is multifactorial: follicular hyperkeratinization, bacteria, sebum production, androgens, and inflammation all play a role. The gram-positive microaerophilic bacteria Propionibacterium acnes promotes development of acne lesions by secreting chemotactic factors that attract leukocytes to the follicle, causing inflammation.

In Brief: Absorica for Acne

   
The Medical Letter on Drugs and Therapeutics • January 21, 2013;  (Issue 1408)

The oral retinoid isotretinoin (Accutane, and others) is the most effective drug available for treatment of acne.1 The FDA has recently approved a new oral isotretinoin product (Absorica – Cipher/Ranbaxy) for treatment of severe, recalcitrant nodular acne.

Isotretinoin can completely clear severe nodulocystic lesions, in some cases leading to remission that can persist for years after treatment is stopped. Mucocutaneous adverse effects include dry skin, dry eye, epistaxis, nasopharyngitis, cheilitis, alopecia, eczema, skin fragility and photosensitivity. Musculoskeletal symptoms, hypertriglyceridemia, hepatitis, pancreatitis, pseudotumor cerebri, depression and psychosis can occur.

The manufacturer’s package insert states that isotretinoin has been associated with inflammatory bowel disease, but a recent population-based cohort study found no significant association.2 The drug is a potent human teratogen (pregnancy category X); the prescriber, the pharmacist, the distributors, and the patient must register with iPLEDGE, a computer-based risk management program (www.ipledgeprogram.com).

The recommended dosage is 0.5 to 1 mg/kg/day given in 2 divided doses for 15-20 weeks. Unlike other formulations of isotretinoin, which are highly lipophilic and must be taken with a high-fat meal to achieve therapeutic plasma levels, Absorica can be taken with or without food, but serum concentrations are higher when it is taken with food. It should be taken with a full glass of water to reduce the risk of esophageal irritation. Absorica has not been shown to be more effective or better tolerated than generic formulations of isotretinoin.
