Fluticasone propionate, an inhaled corticosteroid, and salmeterol xinafoate, a long-acting beta2-adrenergic agonist, are now available together in a dry-powder inhaler for maintenance treatment of patients with asthma.

Atomoxetine (Strattera - Lilly) is the first non-stimulant drug to be approved by the FDA for treatment of attention deficit hyperactivity disorder (ADHD). Unlike other drugs approved for use in ADHD, it is not a controlled substance and is approved for use in adults as well as children. Older non-stimulant drugs that have been used to treat ADHD, although not FDA-approved, include the alpha₂-agonist clonidine (Catapres, and others) and the tricyclic antidepressant desipramine (Norpramin, and others) (Medical Letter 1996; 38:109).

Patients with frequent, severe or disabling migraine headaches may benefit from taking a drug to prevent the attacks. Beta-blockers traditionally have been the prophylactic treatment of choice, but in recent years some antiepileptic drugs such as valproate (Depakote, and others) and topiramate (Topamax) have also been used for this indication. Valproate was approved by the FDA for such use in 1996. Now topiramate has also been approved.

Duloxetine hydrochloride (Cymbalta - Lilly), a selective serotonin and norepinephrine reuptake inhibitor (SNRI) available for treatment of depression, has also been approved by the FDA for treatment of neuropathic pain associated with diabetic peripheral neuropathy (DPN). Duloxetine is one of two drugs approved specifically for management of neuropathic pain due to diabetes; the other, pregabalin (Lyrica - Pfizer), will be marketed soon and will be reviewed in the next issue of The Medical Letter.

The FDA has approved loteprednol etabonate ophthalmic suspension 0.25% (Eysuvis – Kala) for short-term treatment (≤2 weeks) of dry eye disease.

Since the last Medical Letter article on surgical correction of refractive errors (Volume 41, page 122, 1999), some new techniques have been tried and new results have been reported.

The FDA has approved a fixed-dose, orally inhaled combination of the long-acting anticholinergic tiotropium and the long-acting beta2-adrenergic agonist olodaterol (Stiolto Respimat — Boehringer Ingelheim) for long-term, once-daily, maintenance treatment of airflow obstruction in chronic obstructive pulmonary disease (COPD). It is not approved for treatment of acute exacerbations of COPD or for treatment of asthma. Tiotropium (Spiriva Handihaler, Spiriva Respimat) and olodaterol (Striverdi Respimat) are also available separately for once-daily treatment of...
