In overactive bladder, involuntary bladder contractions due to detrusor overactivity result in urinary urgency, frequency, nocturia, and incontinence. The prevalence of the disorder increases with age. Nonpharmacologic treatment, including bladder training, urge suppression, pelvic floor muscle exercises, constipation management, modification of fluid intake, and avoidance of dietary irritants such as alcohol and caffeine, should be tried first.

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.

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 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.

An oral nonopioid analgesic is often sufficient for acute treatment of mild to moderate migraine pain without severe nausea or vomiting. A triptan is the drug of choice for treatment of moderate to severe migraine in most patients without vascular disease. Treatment of pain when it is still mild to moderate in intensity improves headache response and reduces the risk of recurrence.

Exenatide injection (Byetta - Amylin/Lilly), a synthetic peptide that stimulates release of insulin from pancreatic beta cells, has been approved by the FDA as adjunctive therapy for patients with type 2 diabetes who have not achieved optimal glycemic control on metformin (Glucophage, and others), a sulfonylurea, such as glyburide (DiaBeta, and others), or both. Exenatide is not indicated for use with insulin.

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.

The FDA has approved deutetrabenazine (Austedo – Teva), a vesicular monoamine transporter 2 (VMAT2) inhibitor, for treatment of chorea associated with Huntington's disease and, more recently, for treatment of tardive dyskinesia in adults. It is the second VMAT2 inhibitor to be approved for each of these indications; tetrabenazine (Xenazine, and generics) was approved earlier for Huntington's chorea and valbenazine (Ingrezza) was recently approved for treatment of adults with tardive dyskinesia.
