To the Editor.—
Psoriasiform eruptions of the skin are recognized as one of the adverse effects of practolol and other β-adrenergic blocking agents.1-3 With practolol, the cutaneous syndromes have occurred in association with ocular lesions,3 sclerosing peritonitis,4 and systemic lupus erythematosus.5 Voorhees recently suggested that psoriasis may be precipitated or exacerbated in a third of patients with psoriasis treated with oral propranolol hydrochloride.6Cetamolol hydrochloride is a cardioselective β-blocking drug with intrinsic sympathomimetic activity that has been under clinical investigation in multicenter trials for hypertension and coronary artery disease since 1983. We describe herein a patient taking cetamolol who developed psoriasis that was resistant to phototherapy, but that cleared rapidly on discontinuing the drug. Rechallenge of this patient several months later with cetamolol resulted in a recurrence of the psoriatic lesions.
