Rimegepant is a medicinal product that is in clinical development as an oral tablet for acute treatment of migraine in adults. Rimegepant works by blocking a receptor called calcitonin gene-related peptide (CGRP). This receptor plays an important role in migraine pathophysiology. A migraine is usually a moderate or severe headache felt as a throbbing pain on one side of the head. Many people also have symptoms such as nausea, vomiting and increased sensitivity to light or sound. Migraines may be with aura (specific warning signs just before the migraine begins, such as seeing flashing lights), although the most common type is without aura (no specific warning signs). Migraine is a common health condition, affecting around one in every five women and around one in every 15 men.
Rimegepant potentially offers an alternative to current agents, particularly for patients who have contraindications to the use of triptans. This includes patients with underlying cardiovascular diseases, or who either do not respond or have inadequate or inconsistent response to triptans or are intolerant to them.
Bupivacaine and meloxicam (HTX-011) in a fixed-dose combination is in development for the management of post-operative pain. Post-operative pain is a typical example of acute pain. Acute pain typically lasts for less than 3-6 months (unlike chronic pain which carries on for longer than 12 weeks), and is provoked by identifiable stimuli and disappears as soon as the tissue injury or damage that had caused it is healed. All surgical procedures are associated with a certain level of post-operative pain. Opioids are often used to manage post-operative pain but carry the risk of harmful side effects, abuse and addiction.
