Tramadol (Ultram, and others) and gabapentin (Neurontin, and others) are increasingly being prescribed for treatment of chronic pain despite reports of serious adverse events associated with their use. Both drugs are touted as safer and less addictive than strong opioids, but supporting evidence is lacking.

About 50% of the world’s population is infected with Helicobacter pylori. These gastric bacteria can cause chronic inflammation and have been associated with development of gastritis, peptic ulcer disease, gastric adenocarcinoma, and gastric mucosa-associated lymphoid tissue (MALT) lymphoma. Eradication of H. pylori can promote gastric healing, prevent recurrence of duodenal and gastric ulcers, and reduce the incidence of gastric cancer. Guidelines for treatment of H. pylori infection were updated recently.

Gabapentin (Neurontin - Pfizer), which has been available in the US since 1994, is approved by the FDA only for treatment of partial epilepsy and postherpetic neuralgia, but is widely used off-label for a number of other indications, especially neuropathic pain syndromes. According to one report, among Medicaid recipients in Florida receiving gabapentin, 71% of prescriptions were for chronic pain and 8% for seizures and neuralgia ("The Pink Sheet" February 2, 2004; 66:30).

The FDA has approved eptinezumab-jjmr (Vyepti – Lundbeck), a calcitonin gene-related peptide (CGRP) antagonist administered IV once every 3 months, for migraine prevention in adults. It is the fourth monoclonal antibody to be approved for this indication; erenumab (Aimovig), fremanezumab (Ajovy), and galcanezumab (Emgality), which are all given subcutaneously once monthly (fremanezumab can also be given once every 3 months), were approved earlier.

Acamprosate calcium (Campral - Forest) is now being marketed for oral use to maintain abstinence from alcohol. It has been used in France and other countries since 1989.

Pregabalin (Lyrica - Pfizer), a structural analog of gamma-aminobutyric acid (GABA) similar to gabapentin (Neurontin - Pfizer, and others), which recently became available generically, has been approved by the FDA for treatment of neuropathic pain associated with postherpetic neuralgia (PHN) and diabetic peripheral neuropathy (DPN), and for adjunctive treatment of partial onset seizures in adults with epilepsy.

MoviPrep (Salix) is a new polyethylene glycol (PEG)-based bowel cleansing preparation approved for use in adults prior to colonoscopy. It contains ascorbic acid, which acts as an additional cathartic and flavoring agent, and requires a lower volume of fluid (3 L compared to the traditional 4 L) than most other PEG products. HalfLytely is an FDA-approved 2-L PEG product, but it must be taken with bisacodyl.

The FDA has approved sotatercept-csrk (Winrevair – Merck), a first-in-class activin signaling inhibitor, to increase exercise capacity, improve WHO functional class, and reduce the risk of clinical worsening events in adults with WHO Group 1 pulmonary arterial hypertension (PAH).
