Acne is common among adolescents and adults. Guidelines for treatment of acne were last published by the American Academy of Dermatology in 2016.

Emrosi (Journey), an oral, low-dose, biphasic-release formulation of the tetracycline antibiotic minocycline, has been approved by the FDA for once-daily treatment of inflammatory lesions of rosacea (papules and pustules) in adults. Low-dose, biphasic-release doxycycline (Oracea, and generics) has been available for years for treatment of papulopustular rosacea.

Clostridioides (formerly Clostridium) difficile infection (CDI) is the most common infectious cause of healthcare-associated diarrhea in adults. Guidelines on management of CDI have recently been updated.

The FDA has approved Exblifep (Allecra), a fixed-dose combination of the cephalosporin cefepime and the beta-lactamase inhibitor enmetazobactam, for IV treatment of adults with complicated urinary tract infections (cUTIs), including pyelonephritis, caused by designated susceptible microorganisms (see Spectrum of Activity). Exblifep is the first product that contains enmetazobactam to be approved in the US.

The FDA has approved vonoprazan, a potassium-competitive acid blocker, copackaged with amoxicillin (Voquezna Dual Pak – Phathom) and with amoxicillin and clarithromycin (Voquezna Triple Pak) for treatment of Helicobacter pylori infection in adults. Vonoprazan is the first potassium-competitive acid blocker to be approved in the US. It has been available in Japan for treatment of various acid-related disorders since 2014. Vonoprazan is not available alone in the US.

The FDA has approved Twyneo (Galderma), a cream containing the retinoid tretinoin and the oxidizing agent benzoyl peroxide, for once-daily topical treatment of acne in patients ≥9 years old.

The FDA has approved Gimoti (Evoke), a nasal spray formulation of the dopamine-2 (D₂) receptor antagonist metoclopramide, for relief of symptoms in adults with acute and recurrent diabetic gastroparesis. Metoclopramide (Reglan, and generics) has been available for years in conventional and orally-disintegrating tablets and in an injectable formulation. It is the only drug that is FDA-approved for treatment of diabetic gastroparesis.

Rosacea is a common, chronic inflammatory facial eruption of unknown cause. It is more prevalent in women than in men, and disease onset typically occurs after age 30. Rosacea is characterized by erythema, telangiectasia, and flushing, and sometimes by recurrent, progressive crops of acneiform papules and pustules, usually on the central part of the face. Some patients develop granulomas and tissue hypertrophy, which may lead to rhinophyma (a bulbous nose), particularly in men. Blepharitis and conjunctivitis are common. Keratitis and corneal scarring occur rarely.

Gastroesophageal reflux disease (GERD) is the most common GI condition encountered in the outpatient setting; it affects about 20% of people in the US.

The FDA has approved loteprednol etabonate ophthalmic suspension 0.25% (Eysuvis – Kala) for short-term treatment (≤2 weeks) of dry eye disease. It is the first ocular corticosteroid to be approved for this indication. Other formulations of loteprednol are approved for treatment of steroid-responsive ocular inflammatory conditions, inflammation after ocular surgery, and seasonal allergic conjunctivitis.
