A new CDC guideline for prescribing opioids for pain recently became available. Nonopioid drugs for pain were reviewed in a previous issue.

The FDA has approved Seglentis (Esteve/Kowa), an oral combination of tramadol hydrochloride, a weak opioid agonist and weak serotonin and norepinephrine reuptake inhibitor (SNRI), and celecoxib, a COX-2 selective nonsteroidal anti-inflammatory drug (NSAID), for use in adults with acute pain that is severe enough to require an opioid and for which alternative treatment options are inadequate.

The FDA has required new warnings in the labels of gabapentin (Neurontin, and others) and pregabalin (Lyrica, Lyrica CR, and generics) about the risk of life-threatening or fatal respiratory depression in patients with respiratory risk factors. Respiratory risk factors include chronic obstructive pulmonary disease (COPD) and concurrent use of opioids or other CNS depressants. Elderly patients are also at increased risk.

The FDA has approved Anjeso (Baudax Bio), an IV formulation of the nonsteroidal anti-inflammatory drug (NSAID) meloxicam, for once-daily treatment of moderate to severe pain in adults. Oral meloxicam (Mobic, and others), which is only indicated for treatment of chronic pain associated with osteoarthritis or rheumatoid arthritis, has been available for 20 years. IV formulations of ketorolac, ibuprofen (Caldolor), and acetaminophen (Ofirmev) are also available for treatment of pain.

The FDA has approved Combogesic IV (Hikma), an IV solution containing acetaminophen and ibuprofen, to treat mild to moderate pain (alone) or moderate to severe pain (in combination with an opioid) in adults when IV analgesia is considered clinically necessary. Single-drug IV solutions containing ibuprofen (Caldolor) and acetaminophen have been available in the US for years.

Nonopioid drugs can be used in the treatment of many nociceptive and neuropathic pain conditions. For severe pain, especially severe chronic cancer pain, use of opioids may be necessary. Noninvasive nonpharmacologic treatments, including physical and psychological therapies, have been shown to improve pain and function in patients with some common chronic pain conditions and are unlikely to cause serious harms. A multimodal approach to analgesic therapy can increase pain control while reducing opioid use and adverse effects.
