  • What Are the Acute Treatments for Migraine and How Are They Used?
    2. Acute Treatment CQ II-2-1 What are the acute treatments for migraine and how are they used? Recommendation The mainstay of acute treatment for migraine is pharmacotherapy. The drugs used include (1) acetaminophen, (2) non-steroidal anti-inflammatory drugs (NSAIDs), (3) ergotamines, (4) triptans and (5) antiemetics. Stratified treatment according to the severity of migraine is recommended: use NSAIDs such as aspirin and naproxen for mild to moderate headache, and use triptans for moderate to severe headache, or even mild to moderate headache when NSAIDs were ineffective in the past. It is necessary to give guidance and cautions to patients having acute attacks, and explain the methods of using medications (timing, dose, frequency of use) and medication use during pregnancy and breast-feeding. Grade A Background and Objective The objective of acute treatment is to resolve the migraine attack completely and rapidly and restore the patient’s normal functions. An ideal treatment should have the following characteristics: (1) resolves pain and associated symptoms rapidly; (2) is consistently effective; (3) no recurrence; (4) no need for additional use of medication; (5) no adverse effects; (6) can be administered by the patients themselves; and (7) low cost. Literature was searched to identify acute treatments that satisfy the above conditions. Comments and Evidence The acute treatment drugs for migraine generally include (1) acetaminophens, (2) non-steroidal anti-inflammatory drugs (NSAIDs), (3) ergotamines, (4) triptans, and (5) antiemetics. For severe migraines including status migrainosus and migraine attacks refractory to treatment, (6) anesthetics, and (7) corticosteroids (dexamethasone) are used (Tables 1 and 2).1)-9) There are two approaches to the selection and sequencing of these medications: “step care” and “stratified care”.

  • Cyclooxygenase-1 (COX-1) and COX-1 Inhibitors in Cancer: a Review of Oncology and Medicinal Chemistry Literature
    pharmaceuticals Review Cyclooxygenase-1 (COX-1) and COX-1 Inhibitors in Cancer: A Review of Oncology and Medicinal Chemistry Literature Alessandra Pannunzio and Mauro Coluccia * Department of Pharmacy-Drug Sciences, University of Bari “Aldo Moro”, Via E. Orabona 4, I-70125 Bari, Italy; [email protected] * Correspondence: [email protected]; Tel.: +39-080-544-2788 Received: 4 September 2018; Accepted: 9 October 2018; Published: 11 October 2018 Abstract: Prostaglandins and thromboxane are lipid signaling molecules deriving from arachidonic acid by the action of the cyclooxygenase isoenzymes COX-1 and COX-2. The role of cyclooxygenases (particularly COX-2) and prostaglandins (particularly PGE2) in cancer-related inflammation has been extensively investigated. In contrast, COX-1 has received less attention, although its expression increases in several human cancers and a pathogenetic role emerges from experimental models. COX-1 and COX-2 isoforms seem to operate in a coordinate manner in cancer pathophysiology, especially in the tumorigenesis process. However, in some cases, exemplified by the serous ovarian carcinoma, COX-1 plays a pivotal role, suggesting that other histopathological and molecular subtypes of cancer disease could share this feature. Importantly, the analysis of functional implications of COX-1-signaling, as well as of pharmacological action of COX-1-selective inhibitors, should not be restricted to the COX pathway and to the effects of prostaglandins already known for their ability of affecting the tumor phenotype. A knowledge-based choice of the most appropriate tumor cell models, and a major effort in investigating the COX-1 issue in the more general context of arachidonic acid metabolic network by using the systems biology approaches, should be strongly encouraged.
