- Rizatriptan (MAXALT<sup>TM</sup>, Merck & Co., Inc.) is a selective 5-HT<sub>1B/1D</sub> receptor agonist with rapid oral absorption and early onset of action for the acute treatment of migraine. This randomized, double-masked, double-dummy, placebo-controlled study compared rizatriptan 10 mg to naratriptan (NARAMIG<sup>TM</sup>, AMERGE<sup>TM</sup>, both Glaxo Wellcome plc) 2.5 mg in 522 patients treating a single migraine attack. Rizatriptan was more effective than naratriptan. Rizatriptan provided earlier headache relief than naratriptan (hazard ratio 1.62, p < 0.001), acting as early as 30 min. More patients were pain free at 2 h on rizatriptan than on naratriptan (44.8 vs. 20.7%, p < 0.001). Rizatriptan also provided earlier relief of associated migraine symptoms within 2 h than naratriptan and more patients had normal function at 2 h (39.3 vs. 22.6%, p < 0.001). Both active treatments were effective compared to placebo. Both active treatments were well tolerated. The most common side effects with rizatriptan were dizziness, asthenia/fatigue, nausea and somnolence, while the most common side effects with naratriptan were dizziness and asthenia/fatigue.

Tidskriftsartikel (refereegranskat)abstract
- This discussion about advanced cardiac life support (ACLS) reflects disappointment with the over 50% of out-of-hospital cardiopulmonary resuscitation (CPR) attempts that fail to achieve restoration of spontaneous circulation (ROSC). Hospital discharge rates are equally poor for in-hospital CPR attempts outside special care units. Early bystander CPR and early defibrillation (manual, semi-automatic or automatic) are the most effective methods for achieving ROSC from ventricular fibrillation (VF). Automated external defibrillation (AED), which is effective in the hands of first responders in the out-of-hospital setting, should also be used and evaluated in hospitals, inside and outside of special care units. The first countershock is most important. Biphasic waveforms seem to have advantages over monophasic ones. Tracheal intubation has obvious efficacy when the airway is threatened. Scientific documentation of specific types, doses, and timing of drug treatments (epinephrine, bicarbonate, lidocaine, bretylium) are weak. Clinical trials have failed so far to document anything statistically but a breakthrough effect. Interactions between catecholamines and buffers need further exploration. A major cause of unsuccessful attempts at ROSC is the underlying disease, which present ACLS guidelines do not consider adequately. Early thrombolysis and early coronary revascularization procedures should also be considered for selected victims of sudden cardiac death. Emergency cardiopulmonary bypass (CPB) could be a breakthrough measure, but cannot be initiated rapidly enough in the field due to technical limitations. Open-chest CPR by ambulance physicians deserves further trials. In searches for causes of VF, neurocardiology gives clues for new directions. Fibrillation and defibrillation thresholds are influenced by the peripheral sympathetic and parasympathetic nervous systems and impulses from the frontal cerebral cortex. CPR for cardiac arrest of the mother in advanced pregnancy requires modifications and outcome data. Until more recognizable critical factors for ROSC are identified, titrated sequencing of ACLS measures, based on physiologic rationale and sound judgement, rather than rigid standards, gives the best chance for achieving survival with good cerebral function.
