In addition to the seizure type, the choice of drug is usually based on factors such as ease of use, spectrum of activity, adverse effects, interactions with other drugs, presence of comorbid conditions, suitability for elderly persons and those with childbearing potential, and cost.

Bexagliflozin (Brenzavvy – TheracosBio), a sodium-glucose cotransporter 2 (SGLT2) inhibitor, has been approved by the FDA to improve glycemic control in adults with type 2 diabetes. It is the fifth SGLT2 inhibitor to be approved in the US for this indication (see Table 4).

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.
