Sumatriptan-naproxen fixed combination for acute treatment of migraine: a critical appraisal

Migraine

Migraine affects about 1 billion people worldwide, and up to 15% of adults in the United States have migraine attacks in any given year. Migraine is associated with substantial adverse socioeconomic and personal effects. It is the second leading cause of years lived with disability worldwide for all ages and the leading cause in women aged 15 to 49 years. Diagnostic uncertainty increases the likelihood of unnecessary investigations and suboptimal management. This article advises clinicians about diagnosing migraine, ruling out secondary headache disorders, developing acute and preventive treatment plans, and deciding when to refer the patient to a specialist.

Immunomodulatory agents for COVID-19 treatment: possible mechanism of action and immunopathology features

The novel coronavirus pandemic has emerged as one of the significant medical-health challenges of the current century. The World Health Organization has named this new virus severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Since the first detection of SARS-CoV-2 in November 2019 in Wuhan, China, physicians, researchers, and others have made it their top priority to find drugs and cures that can effectively treat patients and reduce mortality rates. The symptoms of Coronavirus Disease 2019 (COVID-19) include fever, dry cough, body aches, and anosmia. Various therapeutic compounds have been investigated and applied to mitigate the symptoms in COVID-19 patients and cure the disease. Degenerative virus analyses of the infection incidence and COVID-19 have demonstrated that SARS-CoV-2 penetrates the pulmonary alveoli's endothelial cells through Angiotensin-Converting Enzyme 2 (ACE2) receptors on the membrane, stimulates various signaling pathways and causes excessive secretion of cytokines. The continuous triggering of the innate and acquired immune system, as well as the overproduction of pro-inflammatory factors, cause a severe condition in the COVID-19 patients, which is called "cytokine storm". It can lead to acute respiratory distress syndrome (ARDS) in critical patients. Severe and critical COVID-19 cases demand oxygen therapy and mechanical ventilator support. Various drugs, including immunomodulatory and immunosuppressive agents (e.g., monoclonal antibodies (mAbs) and interleukin antagonists) have been utilized in clinical trials. However, the studies and clinical trials have documented diverging findings, which seem to be due to the differences in these drugs' possible mechanisms of action. These drugs' mechanism of action generally includes suppressing or modulating the immune system, preventing the development of cytokine storm via various signaling pathways, and enhancing the blood vessels' diameter in the lungs. In this review article, multiple medications from different drug families are discussed, and their possible mechanisms of action are also described.

Voltammetric detection of sumatriptan in the presence of naproxen using Fe3O4@ZIF-8 nanoparticles modified screen printed graphite electrode

A novel electrochemical sensing platform was designed and prepared for the simultaneous detection of sumatriptan and naproxen by exploiting the prowess of the Fe₃O₄@ZIF-8 nanoparticles (NPs); as-synthesized Fe₃O₄@ZIF-8 NPs were characterized by energy-dispersive X-ray spectroscopy, fourier transform infrared spectroscopy, X-ray diffraction, field emission scanning electron microscopy (FESEM), transmission electron microscopy and thermal gravimetric analysis. The immobilized Fe₃O₄@ZIF-8 NPs on a screen printed graphite electrode (SPGE) was evaluated electrochemically via cyclic voltammetry, linear sweep voltammetry, and differential pulse voltammetry as well as chronoamprometery means; Fe₃O₄@ZIF-8/SPGE exhibited good sensing performance for sumatriptan in a range of 0.035–475.0 µM with detection limit of 0.012 µM. Also, Fe₃O₄@ZIF-8/SPGE exhibited good sensing performance for naproxen in a range of 0.1–700.0 µM with detection limit of 0.03 µM. The modified electrode showed two separate oxidative peaks at 620 mV for sumatriptan and at 830 mV for naproxen with a peak potential separation of 210 mV which was large enough to detect the two drugs simultaneously besides being stable in the long-run with considerable reproducibility. Real sample analyses were carried out to identify the function of fabricated electrode in sensing applications wherein trace amounts of sumatriptan and naproxen could be identified in these samples.

Modulation of brain networks by sumatriptan-naproxen in the inflammatory soup migraine model

Migraine is a debilitating condition; however, the pharmacological effects on central nervous system networks after successful therapy are poorly understood. Defining this neurocircuitry is critical to our understanding of the disorder and for the development of antimigraine drugs. Using an established inflammatory soup model of migraine-like pathophysiology (N = 12) compared with sham synthetic interstitial fluid migraine induction (N = 12), our aim was to evaluate changes in network-level functional connectivity after sumatriptan-naproxen infusion in awake, conscious rodents (Sprague-Dawley rats). Sumatriptan-naproxen infusion functional magnetic resonance imaging data were analyzed using an independent component analysis approach. Whole-brain analysis yielded significant between-group (inflammatory soup vs synthetic interstitial fluid) alterations in functional connectivity across the cerebellar, default mode, basal ganglia, autonomic, and salience networks. These results demonstrate the large-scale antimigraine effects of sumatriptan-naproxen co-administration after dural sensitization.

The fifth cranial nerve in headaches

The fifth cranial nerve is the common denominator for many headaches and facial pain pathologies currently known. Projecting from the trigeminal ganglion, in a bipolar manner, it connects to the brainstem and supplies various parts of the head and face with sensory innervation. In this review, we describe the neuroanatomical structures and pathways implicated in the sensation of the trigeminal system. Furthermore, we present the current understanding of several primary headaches, painful neuropathies and their pharmacological treatments. We hope that this overview can elucidate the complex field of headache pathologies, and their link to the trigeminal nerve, to a broader field of young scientists.

Liposomal Curcumin Enhances the Effect of Naproxen in a Rat Model of Migraine

BACKGROUND Curcumin is an antioxidant that reduces inflammation and pain. This study aimed to assess the effect of pretreatment with naproxen and liposomal curcumin compared with naproxen and curcumin solution on oxidative stress parameters and pain in a rat model of migraine. MATERIAL AND METHODS Sixty-three male Wistar rats included a control group (n=9) and a rat model of migraine (n=54) induced by intraperitoneal injection of nitroglycerin (1 mg/0.1 kg). The rat model group was divided into an untreated control group (n=9), a group pretreated with naproxen alone (2.8 mg/kg) (n=9), a group pretreated with naproxen (2.8 mg/kg) combined with curcumin solution (1 mg/0.1 kg) (n=9), a group pretreated with naproxen (2.8 mg/kg) combined with curcumin solution (2 mg/0.1 kg) (n=9), a group pretreated with naproxen (2.8 mg/kg) combined with liposomal curcumin solution (1 mg/0.1 kg) (n=9) a group pretreated with naproxen (2.8 mg/kg) combined with liposomal curcumin solution (2 mg/0.1 kg) (n=9). Spectroscopy measured biomarkers of total oxidative status and nociception was tested using an injection of 1% of formalin into the rat paw. RESULTS Expression of biomarkers of oxidative stress and enhanced nociception were significantly increased following pretreatment with combined naproxen and liposomal curcumin compared with curcumin solution or naproxen alone (P<0.001). Combined curcumin solution and naproxen were more effective at a concentration of 2 mg/0.1kg for the first nociceptive phase (P<0.005). CONCLUSIONS In a rat model of migraine, combined therapy with liposomal curcumin and naproxen showed an improved antioxidant effect and anti-nociceptive effect.

Recognition and Optimization of Ingredients Treating Nitroglycerin-Induced Migraine Rats from Wuzhuyu Decoction

Wuzhuyu decoction (WZYD) has been clinically used to treat migraine effectively since Eastern Han Dynasty of ancient China. However, its antimigrainic ingredients remain unclear. In present study, the antimigrainic ingredients of WZYD were explored and optimized in nitroglycerin-induced migraine rats through correlation analysis of decoction spectra-pharmacological effects and absorption spectra-pharmacological using entropy-weighted partial least squares regression method. The decoction spectra and absorption spectra were obtained through the determination of nine main ingredients in ten kinds of WZYDs and WZYDs' single-pass intestinal perfusion samples using high performance liquid chromatography-diode array detector. The pharmacodynamics indexes related to migraine model rats were detected using high performance liquid chromatography method and kits after oral administration of WZYDs. Then, the key ingredients influencing indexes were achieved through the correlation analysis. And the optimization of key ingredients was acquired through uniform design experiment. The pharmacodynamic verification test was used to clarify the advantages of the optimized sample. The results showed that the final optimized sample, in which the concentrations of rutaecarpine, evodiamine, ginsendside Rb₁, 6-gingerol, ginsendside Rg₁, rutaevine, and limonin were 0.081, 0.565, 1.455, 0.159, 0.871, 0.178, and 0.009 mg·mL⁻¹, respectively, provided the best comprehensive effect than another optimized sample and the best uniform design sample. Therefore, a new reliable method for rapidly recognizing and optimizing the effective constituents of WZYD treating migraine was established.

Sumatriptan plus naproxen for the treatment of acute migraine attacks in adults

BACKGROUND

This is an updated version of the original Cochrane review published in October 2013 on 'Sumatriptan plus naproxen for acute migraine attacks in adults'.Migraine is a common disabling condition and a burden for the individual, health services, and society. It affects two to three times more women than men, and is most common in the age range 30 to 50 years. Effective abortive treatments include the triptan and non-steroidal anti-inflammatory classes of drugs. These drugs have different mechanisms of action and combining them may provide better relief. Sumatriptan plus naproxen is now available in combination form for the acute treatment of migraine.

OBJECTIVES

To determine the efficacy and tolerability of sumatriptan plus naproxen, administered together as separate tablets or taken as a fixed-dose combination tablet, compared with placebo and other active interventions in the treatment of acute migraine attacks in adults.

SEARCH METHODS

For this update we searched the Cochrane Central Register of Controlled Trials (CENTRAL) via The Cochrane Register of Studies Online (CRSO) to 28 October 2015, MEDLINE (via Ovid) from 1946 to 28 October 2015, and EMBASE (via Ovid) from 1974 to 28 October 2015, and two online databases (www.gsk-clinicalstudyregister.com and www.clinicaltrials.gov). We also searched the reference lists of included studies and relevant reviews.

SELECTION CRITERIA

We included randomised, double-blind, placebo- or active-controlled studies, with at least 10 participants per treatment arm, using sumatriptan plus naproxen to treat a migraine headache episode.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed trial quality and extracted data. We used numbers of participants achieving each outcome to calculate risk ratio and numbers needed to treat for an additional beneficial outcome (NNT) or for an additional harmful outcome (NNH) compared with placebo or a different active treatment.

MAIN RESULTS

For this update we identified one new study (43 participants), but it did not contribute any data for analysis. The review included 13 studies using sumatriptan 85 mg or 50 mg plus naproxen 500 mg to treat attacks of mild, moderate, or severe pain intensity. Twelve studies contributed data for analyses: 3663 participants received combination treatment, 3682 placebo, 964 sumatriptan, and 982 naproxen. We judged only one small study to be at high risk of bias for any of the criteria evaluated; it did not contribute to any analyses.Overall, the combination was better than placebo for the primary outcomes of pain-free and headache relief at two hours. The NNT for pain-free at two hours was 3.1 (95% confidence interval 2.9 to 3.5) when the baseline pain was mild (50% response with sumatriptan plus naproxen compared with 18% with placebo), and 4.9 (4.3 to 5.7) when baseline pain was moderate or severe (28% with sumatriptan plus naproxen compared with 8% with placebo) (high quality evidence). Using 50 mg of sumatriptan, rather than 85 mg, in the combination did not significantly change the result. Treating early, when pain was still mild, was significantly better than treating once pain was moderate or severe for pain-free responses at two hours and during the 24 hours post dose. Adverse events were mostly mild or moderate in severity and rarely led to withdrawal; they were more common with the combination than with placebo (moderate quality evidence).Where the data allowed direct comparison, combination treatment was superior to either monotherapy, but adverse events were less frequent with naproxen than with sumatriptan (moderate quality evidence).

AUTHORS' CONCLUSIONS

The conclusions of this review were not changed. Combination treatment was effective in the acute treatment of migraine headaches. The effect was greater than for the same dose of either sumatriptan or naproxen alone, but additional benefits over sumatriptan alone were not large. More participants achieved good relief when medication was taken early in the attack, when pain was still mild. Adverse events were more common with the combination and sumatriptan alone than with placebo or naproxen alone.

Pharmacological treatment of acute migraine in adolescents and children

Migraine is a common disease in children and adolescents. The incidence of migraine has increased alarmingly in the general population during recent decades. Migraine causes considerable individual suffering and impaired quality of life. Therefore, appropriate management is essential. In this article, the treatment of acute migraine in children and adolescents will be reviewed. Only a few randomized controlled studies have been published and high placebo rates are a major problem for proving superiority of active drugs. Generally, acetaminophen (paracetamol) and ibuprofen are accepted as drugs of first choice, even though the evidence is poor for the former and limited for latter. Among 14 studies on triptans in adolescents, 9 showed some superiority over placebo with respect to pain relief and pain freedom, and among 6 studies in children, 5 suggest some superiority over placebo. Sumatriptan nasal spray and zolmitriptan nasal spray have been approved for adolescents in Europe; almotriptan has been approved for adolescents in the USA, as has rizatriptan for patients aged 6-17 years. A recent study demonstrated the efficacy of a fixed combination of sumatriptan and naproxen in adolescents with migraine. In conclusion, evidence for the pharmacological treatment of acute migraine in children is very poor and evidence for adolescents is better but still limited.

Efficacy, end points and eventualities: sumatriptan/naproxen versus butalbital/paracetamol/caffeine in the treatment of migraine

Migraine is a widespread, relapsing, remittent syndrome. No animal model predicts whether test medications will be clinically useful. Using a modern, well-controlled, sophisticated study design, Derosier et al. demonstrates not only that a butalbital formulation has modest efficacy as an acute treatment for migraine but also that a sumatriptan-naproxen combination is superior. These conclusions are reached using a variety of internally consistent secondary efficacy end points. The primary end point chosen (highly conservative and fashionable in some academic circles) was a technical failure (and not a negative experimental finding). Migraine is intrinsically pleiomorphic: diverse treatment options help match patient with therapy. This study does not justify blanket bans on (admittedly hazardous) barbiturate therapies, and regulators should not impose end point conservatism to an extent that will stifle further progress.

Overview of migraine treatment

SUMMARY Migraine is ranked as the 19th top cause of disability worldwide by WHO. Despite advancements in migraine-specific acute treatment, only a minority of patients utilize these medications. Specific pharmacologic treatments consist of the ergot alkaloids and triptans (serotonin 5-HT1B/1D receptor agonists). Both classes are regarded as relatively safe and effective; however, there is a greater concern for vasoconstrictive effects with the ergots, which limits their use. Triptans transformed migraine therapy, setting in motion revolutionary research that heightened our understanding of migraine mechanisms. However, one in three migraineurs may be triptan nonresponders and there is a group of migraine patients that remains ‘refractory’ to conventional pharmacologic migraine therapy. This article discusses the approach to migraine management, reviews currently available acute and preventive pharmacologic and nonpharmacologic treatment options for migraine headache, as well as briefly focuses on novel and upcoming medicines presently under investigation.

Identification of cytokines and signaling proteins differentially regulated by sumatriptan/naproxen

OBJECTIVES

The goal of this study was to use protein array analysis to investigate temporal regulation of stimulated cytokine expression in trigeminal ganglia and the spinal trigeminal nucleus in response to co-treatment of sumatriptan and naproxen sodium or individual drug.

BACKGROUND

Activation of neurons and glia in trigeminal ganglia and the spinal trigeminal nucleus leads to increased levels of cytokines that promote peripheral and central sensitization, which are key events in migraine pathology. While recent clinical studies have provided evidence that a combination of sumatriptan and naproxen sodium is more efficacious in treating migraine than either drug alone, it is not well understood why the combination therapy is superior to monotherapy.

METHODS

Male Sprague-Dawley rats were left untreated (control), injected with capsaicin, or pretreated with sumatriptan/naproxen, sumatriptan, or naproxen for 1 hour prior to capsaicin. Trigeminal ganglia and the spinal trigeminal nucleus were isolated 2 and 24 hours after capsaicin or drug treatment, and levels of 90 proteins were determined using a RayBio® Label-Based Rat Antibody Array (RayBiotech, Norcross, GA, USA).

RESULTS

Capsaicin stimulated a >3-fold increase in expression of the majority of cytokines in trigeminal ganglia at 2 hours that was sustained at 24 hours. Significantly, treatment with sumatriptan/naproxen almost completely abolished the stimulatory effects of capsaicin at 2 and 24 hours. Capsaicin stimulated >3-fold expression of more proteins in the spinal trigeminal nucleus at 24 hours when compared to 2 hours. Similarly, sumatriptan/naproxen abolished capsaicin stimulation of proteins in the spinal trigeminal nucleus at 2 hours and greatly suppressed protein expression 24 hours post-capsaicin injection. Interestingly, treatment with sumatriptan alone suppressed expression of different cytokines in trigeminal ganglia and the spinal trigeminal nucleus than repressed by naproxen sodium.

CONCLUSION

We found that the combination of sumatriptan/naproxen was effective in blocking capsaicin stimulation of pro-inflammatory proteins implicated in the development of peripheral and central sensitization in response to capsaicin activation of trigeminal neurons. Based on our findings that sumatriptan and naproxen regulate expression of different proteins in trigeminal ganglia and the spinal trigeminal nucleus, we propose that these drugs function on therapeutically distinct cellular targets to suppress inflammation and pain associated with migraine.

Indomethacin/prochlorperazine/caffeine: a review of its use in the acute treatment of migraine and in the treatment of episodic tension-type headache

The indomethacin/prochlorperazine/caffeine fixed combination (Difmetré®) combines the NSAID indomethacin with the phenothiazine antiemetic prochlorperazine and caffeine. It is currently available as two oral (effervescent tablet and coated tablet) and two rectal (suppository and low-dose suppository) formulations. Oral and rectal formulations of indomethacin/prochlorperazine/caffeine were effective and generally well tolerated in the treatment of migraine and episodic tension-type headache (TTH) in adult patients participating in randomized, multicentre, active-comparator controlled studies. For the most part, the efficacy of oral indomethacin/prochlorperazine/caffeine did not significantly differ from that of oral sumatriptan in patients with migraine and oral nimesulide in patients with episodic TTH. With rectal administration, indomethacin/prochlorperazine/caffeine was, in general, significantly more effective than sumatriptan in patients with migraine. Thus, oral and rectal formulations of indomethacin/prochlorperazine/caffeine provide a further option in the acute treatment of migraine and in the treatment of episodic TTH in adult patients.
