The FDA has approved obiltoxaximab (Anthim – Elusys Therapeutics), a toxin-targeting monoclonal antibody, for treatment of inhalational anthrax in combination with antibacterial drugs and prophylaxis of inhalational anthrax when other therapies are unavailable or inappropriate. Raxibacumab, another monoclonal antibody, was approved earlier for the same indication. Like raxibacumab, obiltoxaximab is being manufactured only for the CDC national stockpile and is not available for commercial sale.

Epsolay (Galderma), a 5% benzoyl peroxide cream, has been approved by the FDA for treatment of inflammatory lesions of rosacea in adults. It is the first product containing benzoyl peroxide to be approved in the US for treatment of rosacea. Benzoyl peroxide formulations approved for acne have been used off-label to treat rosacea for years, but itching and burning have limited their use.

Xerostomia, dry mouth due to decreased or absent saliva, is a common problem, particularly among elderly patients. Decreased salivary flow can be due to many different conditions, including drug therapy, Sj gren's syndrome (keratoconjunctivitis sicca) or radiation of the salivary glands.

Since the implication of aspirin in Reye's syndrome, acetaminophen (Tylenol; and others) has become the standard drug for symptomatic treatment of fever and pain in children. Ibuprofen, a nonsteroidal anti-inflammatory drug (NSAID) available for many years in tables (Mortin; Advil; and others), has now become available in a suspension. The suspension will be sold by presecription for treatment of fever or arthritis in children.

Felodipine (Plendil - Merck), an extended-release preparation of a dihydropyridine calcium-channel blocker was recently marketed in the USA for oral treatment of hypertension. An immediate-release formulation is available in some other countries.

Captopril (Capoten - Bristol-Myers Squibb), an angiotensin-converting enzyme (ACE) inhibitor previously available for treatment of hypertension, has now been approved by the US Food and Drug Administration (FDA) for treatment of diabetic nephropathy in patients with insulin-dependent diabetes mellitus (IDDM). Diabetic nephropathy is the most common cause of end-stage renal disease in the United States.

An intranasal formulation of the corticosteroid budesonide (Rhinocort Nasal Inhaler - Astra) was recently approved by the US Food and Drug Administration for treatment of seasonal or perennial allergic rhinitis in adults and children and nonallergic perennial rhinitis in adults. Budesonide has been available in Canada and Europe for several years for inhalation treatment of both allergic rhinitis and asthma.

Midodrine hydrochloride (ProAmatine - Roberts), an alpha1-selective adrenergic agonist, is now available for treatment of severe symptomatic orthostatic hypotension. Other treatments for this condition include other sympathomimetics, constrictive garments, erythropoietin (Epogen; Procrit) and fludrocortisone with salt (D Robertson and TL Davis, Neurology, 45 suppl 5: S26, 1995).

Basiliximab (Simulect - Novartis) and daclizumab (Zenapax - Roche), two mouse/human monoclonal antibodies that block the interleukin-2 (IL-2) receptor on Tlymphocytes, have been approved by the FDA for use in the prevention of acute renal transplant rejection. Both drugs are used with cyclosporine (Sandimmune; Neoral) and corticosteroids. An all-murine anti-CD3 monoclonal antibody, muromonab-CD3 (Orthoclone OKT3), has been available in the USA for many years for treatment of transplant rejection, and has also been used with some success for prophylaxis (MI Wilde and KL Goa, Drugs,...
