The Vibrant orally administered vibrating capsule (Vibrant Gastro), an FDA-cleared medical device, is now available by prescription for treatment of adults with chronic idiopathic constipation (CIC) who have not experienced relief of their bowel symptoms by using laxative therapies at the recommended dosage for at least one month. It is the first drug-free treatment to be authorized by the FDA for this indication.

The FDA has approved zavegepant nasal spray (Zavzpret – Pfizer) for acute treatment of migraine with or without aura in adults. Zavzpret is the first nasal spray formulation of a calcitonin gene-related peptide (CGRP) receptor antagonist ("gepant") to become available in the US.

A 10-year study of daily oral alendronate (Fosamax) and a 7-year study of daily oral risedronate (Actonel) indicate that both drugs maintained increases in bone mineral density (BMD) and decreases in markers of bone remodeling throughout the study period. Both drugs are now more commonly taken once weekly. Available data are insufficient to compare fracture rates with alendronate and risedronate, and fracture rates are considered the most important endpoint in osteoporosis studies. Recent reports of severe pain and jaw osteonecrosis with these drugs are disturbing.

Treatment options for snoring and obstructive sleep apnea (OSA) now include, in addition to lifestyle remedies such as weight loss and avoidance of alcohol in the evening, mechanical devices, injection of botulinum toxin into the soft palate and a variety of ENT surgical outpatient procedures. Palatal implants (Pillar procedure - Restore Medical Inc) have been approved by the FDA for treatment of snoring and OSA.

The most common cause of travelers' diarrhea, usually a self-limited illness without fever lasting several days, is infection with noninvasive enterotoxigenic (ETEC) or enteroaggregative (EAEC) strains of Escherichia coli. Campylobacter, Shigella, Salmonella, Aeromonas, viruses and parasites are less common.

The injectable glucagon-like peptide-1 (GLP-1) receptor agonist liraglutide, previously approved by the FDA for treatment of type 2 diabetes as Victoza, has now also been approved at a higher dose as Saxenda (Novo Nordisk) for chronic weight management in adults with a BMI ≥30, or a BMI ≥27 with a weight-related comorbidity such as hypertension, dyslipidemia, or diabetes.

The FDA has approved the 5-HT4 receptor agonist prucalopride (Motegrity – Shire) for treatment of chronic idiopathic constipation (CIC) in adults. Prucalopride is the only drug currently approved in the US for treatment of CIC that stimulates colonic peristalsis. It has been available in Europe and Canada for several years.

The FDA has approved Trudhesa (Impel Neuropharma), a new dihydroergotamine nasal spray product, for acute treatment of migraine with or without aura in adults. Another dihydroergotamine nasal spray (Migranal, and generics) has been available for many years for the same indication.

The FDA has approved a sublingual film formulation of the alpha-2 adrenergic receptor agonist dexmedetomidine (Igalmi — BioXcel Therapeutics) for acute treatment of agitation associated with schizophrenia or bipolar I or II disorder in adults. It is the first alpha-2 agonist and the only sublingual film to be approved for this indication. Dexmedetomidine has been available for many years in an injectable formulation (Precedex) for sedation in the intensive care unit and to facilitate procedures such as mechanical ventilation.

Some commonly used systemic drugs that may cause pulmonary toxicity are listed in the table below. These adverse effects may sometimes be difficult to distinguish from the underlying disease (JAD Cooper, Jr et al, Am Rev Respir Dis, 133:321, 488, 1986). Pulmonary effects that are part of a generalized reaction or are indirect effects of drugs - on respiratory muscles, for example, or on the immune system - are not included here.
