Abstract
INTRODUCTION Trigeminal neuralgia is a rare condition that can be effectively treated by carbamazepine or oxcarbazepine but these older drugs are associated with dose-dependent and potentially treatment-limiting adverse effects. Third-generation anticonvulsants, new calcitonin gene-related peptide blockers for migraine, and older drugs such as ketamine and cannabinoids may be promising adjuvants or monotherapeutic options. AREAS COVERED The new drugs, their presumed mechanisms of action, safety and efficacy are discussed herein. There is a paucity of robust clinical evidence in support of these drugs for trigeminal neuralgia. New migraine agents are considered as well although migraines and trigeminal neuralgia are distinct, albeit similar, conditions. No new drugs have been released to market in recent years with the specific indication of trigeminal neuralgia. EXPERT OPINION In real-world clinical practice, about half of trigeminal neuralgia patients take more than one agent for prevention and combination therapy may be the optimal approach. Combination therapy might allow for lower doses of carbamazepine or oxcarbazepine, thus reducing the number and severity of potential adverse events but the potential for pharmacokinetic drug-drug interactions must be considered. Drug therapy for trigeminal neuralgia involves acute or abortive treatments, often administered in hospital versus long-term preventive therapy, usually involving oral agents.

Abstract
Migraine is a common neurological disorder that is present in a large proportion of the global population. It is estimated to occur in around 20.7% of women and 10.7% of men in the United States. The pathophysiology of migraine is a major focus of research, and medications have been developed to interrupt the processes that generate headache and other bothersome symptoms of migraine attacks. The triptan class of medications acts as a direct agonist at the 5-HT1B/D receptor but its use is limited by contraindications for those with coronary or cerebrovascular disease. Lasmiditan is a first-in-class agonist at the 5-HT1F serotonin receptor that does not appear to generate vasoconstriction. This article reviews the design, development, and place in therapy for lasmiditan. A narrative review of the literature using the Ovid MEDLINE database was performed. The rationale behind the development of lasmiditan and pre-clinical, proof-of-concept, Phase II, pivotal, Phase III trials and post-hoc data is covered. Additionally, the efficacy and safety of lasmiditan when compared to other acute treatments in migraine is described, including lasmiditan's side effect profile and status as a Schedule V substance. Further, head-to-head studies of lasmiditan compared with other acute treatments are required.

Place of next generation acute migraine specific treatments among triptans, non-responders and contraindications to triptans and possible combination therapies. Cephalalgia 2023; 43:3331024221143773.

Abstract
Background: For many years triptans have been the cornerstone of acute migraine treatment. Nevertheless, treatment with triptans may not always be initiated due to contraindications (seen in approximately one fifth of patients) or inadequate response (seen in approximately one third of patients). New acute therapies, including 5-hydroxytryptamine (5-HT)1F receptor agonists, also known as ditans (lasmiditan) and small molecule antagonists of the calcitonin gene-related peptide receptor, also known as gepants (rimegepant and ubrogepant), may be an effective alternative. Methods: We searched Pubmed for keywords, summarized the literature and provided a comprehensive review on the place of next generation acute migraine specific treatments among triptans. Results and conclusion: Post-hoc analyses reported no differences in efficacy of gepants/ditans between responders and non-responders to triptans, but research is hampered by lack of consensus on the definition of non-responder. Due to (partially) overlapping mechanisms of action, it remains unknown whether combination therapy with lasmiditan, gepants and triptans will have added value over monotherapy. Preclinical studies and post-hoc analyses cautiously indicate that these new drugs are safe for patients with cardiovascular risk factors. However, long-term studies are needed to prove cardiovascular safety. The risk of developing medication overuse headache may differ between triptans, ditans and gepants, but further studies are needed to confirm this difference. Head-to-head randomized controlled trials of acute therapies and combinations of therapies are needed to determine their place in migraine treatment among established therapies.

Abstract
Migraine with brainstem aura (MBA) accompanied by disorders of consciousness (DOC) is a rare subtype of migraine. The pathophysiology of MBA with DOC has not been elucidated yet. Some patients have a family history of migraine, and women are more affected than men. The aura symptoms are diverse; however, when MBA is combined with DOC, the clinical manifestations are more complicated. Coma is the most common clinical manifestation. The overall duration of the patient’s DOC is short and can often return to normal within half an hour. Headache often occurs after regaining consciousness and can also occur at the same time as DOC. The most common headache is located at the occipital region. Although DOC is reversible, considering the current small number of cases, we still need to improve our understanding of the disease to avoid misdiagnosis. The MBA patient’s electroencephalogram and cerebral blood flow perfusion may have transient changes and may return to normal in the interictal period or after the DOC. Although triptans have traditionally been contraindicated in MBA under drug instructions, the evidence of basilar artery constriction, as postulated in MBA, is lacking. Lasmiditan is currently the first and only 5-HT 1F receptor agonist approved by the Food and Drug Administration. The calcitonin gene-related peptide receptor antagonists and monoclonal antibody therapies may be the most promising for future consideration. Here, the pathophysiology, clinical manifestations, diagnostic tools, and treatment progress for MBA with DOC are reviewed.

Abstract
Migraine is a leading cause of morbidity and disability worldwide. Triptans were the first migraine-specific drug class developed and have proven efficacy in treatment of this neurological disease. They are however contraindicated in patients with cardiovascular disease and possibly others, owning to their vasoconstrictive properties. This review will focus on lasmiditan, which has been called the first 'ditan' and 'neurally acting anti-migraine agent', designed to selectively agonize the serotonin 5-HT1F receptor subtype, providing anti-migraine effects without concomitant vasoconstriction. To date, lasmiditan has proven safe and effective for the acute treatment of migraine in two Phase II and four Phase III trials. Post hoc analysis revealed that the majority of treatment-emergent adverse events were CNS-related, mild-to-moderate in severity and self-limiting. The US FDA label recommends that patients not drive or operate machinery until at least 8 h after taking each dose of lasmiditan.

Ferrari A, Rustichelli C. Rational Use of Lasmiditan for Acute Migraine Treatment in Adults: A Narrative Review. Clin Ther 2021; 43:654-670.

Abstract
PURPOSE This narrative review provides an update on the research that led to the development of ditans and lasmiditan for the acute treatment of migraine in adults and discusses the potential advantages and disadvantages of lasmiditan in clinical use. METHODS The electronic databases PubMed, Scopus, and ClinicalTrials.gov were searched from database inception through January 9, 2021, to identify relevant studies. Search results were assessed for their overall relevance to this review. FINDINGS Because part of the effect of the triptans is mediated by the serotonin 1F receptors, which are not present in the smooth muscle, a pure agonist of these receptors, lasmiditan, was developed. Lasmiditan is hypothesized to act on antinociceptive pathways and inhibit the calcitonin gene-related peptide release. Lasmiditan was approved by the US Food and Drug Administration in 2019 based on the results of 2 pivotal trials that found a significant difference from placebo in the percentage of patients who achieved freedom from pain and most bothersome symptom at 2 h. The main concern of lasmiditan derives from its central nervous system-related adverse effects, mainly dizziness and paraesthesia, probably attributable to its high blood brain barrier penetration. These central nervous system adverse effects impair driving performance for hours and might be suboptimal for individuals with migraine who want to quickly stop the migraine attack to resume their activities as soon as possible. IMPLICATIONS Despite the advantage of being beneficial in the acute treatment of migraine without vasocostrictive action, lasmiditan also presents limitations, in particular the central nervous system adverse effects. Moreover, head-to-head trials against triptans and gepants are indispensable to determine the better option for patients.

Abstract
In the last few years, there have been significant advances in migraine management and prevention. Lasmiditan, ubrogepant, rimegepant and monoclonal antibodies (erenumab, fremanezumab, galcanezumab, and eptinezumab) are new drugs that were launched on the US pharmaceutical market; some of them also in Europe. This publication reviews the available worldwide references on the safety of these anti-migraine drugs with a focus on the possible drug–drug (DDI) or drug–food interactions. As is known, bioavailability of a drug and, hence, its pharmacological efficacy depend on its pharmacokinetics and pharmacodynamics, which may be altered by drug interactions. This paper discusses the interactions of gepants and lasmiditan with, i.a., serotonergic drugs, CYP3A4 inhibitors, and inducers or breast cancer resistant protein (BCRP) and P-glycoprotein (P-gp) inhibitors. In the case of monoclonal antibodies, the issue of pharmacodynamic interactions related to the modulation of the immune system functions was addressed. It also focuses on the effect of monoclonal antibodies on expression of class Fc gamma receptors (FcγR).
