Oral triptans in the preventive management of cluster headache.

Cluster headache is a rare primary neurovascular headache and a severe pain condition with unilateral headache over 15-180 minutes and concomitant unilateral autonomic symptoms. The detailed pathophysiology of the condition is still unclear. Only a few evidence-based therapeutic options for acute therapy and the preventive management of the disease are available.

Frovatriptan for prophylactic treatment of cluster headache: lessons for future trial design.

Objective: The aim of this study was to determine whether frovatriptan would show efficacy in short term prophylactic treatment of episodic cluster headache (ECH) in comparison to placebo.

Background: The 5-hydroxytryptamine(1B/d) (5-HT(1B/d) )-agonists naratriptan, eletriptan, and frovatriptan have been shown to reduce the frequency of ECH. So far, no double-blind placebo-controlled trials have investigated the potential prophylactic effects of 5-HT(1B/d) -agonists in ECH.

Clinical relevance of efficacy endpoints in OTC headache trials.

Objective: This analysis evaluates and ranks efficacy endpoints often used in headache trials concerning their clinical relevance in relation to the patient-related criterion "global assessment of overall efficacy" based on data gained in a large trial investigating different over-the-counter drugs in the treatment of headache.

Background: The original study showed a significant superiority of the fixed combination of acetylsalicylic acid+paracetamol+caffeine over the combination without caffeine, the single preparations, and placebo in the treatment of headache.

Methods: For 1734 patients included in the efficacy analysis we investigated the correlation of patient's global efficacy assessment with the endpoints "time to 50% pain relief" (primary endpoint), "time to be pain-free," pain intensity difference, sum of pain intensity difference, and extent of impairment of daily activities.

OTC analgesics in headache treatment: open-label phase vs randomized double-blind phase of a large clinical trial.

Objective: To compare the superior efficacy of the fixed combination of acetylsalicylic acid, paracetamol, and caffeine over the single substances, which was observed in the randomized, double-blind phase of the clinical trial, with the efficacy of the respective usual nonprescription medication taken by the patients in the open-label pre-phase of the same study.

Background: The "Thomapyrin Study" showed significant superiority of the fixed combination containing acetylsalicylic acid, paracetamol, and caffeine over the combination without caffeine, the single preparations, and placebo in the treatment of headache.

Methods: Prior to the randomized treatment phase, a headache episode treated with the patient's usual nonprescription medication was recorded (open-label pre-phase).

Medication-overuse headache.

Medication-overuse headache (MOH) can be caused by almost all anti-headache drugs including analgesics, ergots, triptans, and combined preparations The prevalence of chronic daily headache (CDH) appears to be between 2% and 4% in the general population. Current epidemiologic studies suggest that MOH accounts for approximately 50% of these cases. The pathophysiology of MOH remains unclear.

Comparison of intravenous valproate with intravenous lysine-acetylsalicylic acid in acute migraine attacks.

Objective: The study compared efficacy and tolerability of intravenous valproate (iVPA) with intravenous lysine-acetylsalicylic acid (iLAS) in acute migraine attacks. Background.-iLAS has been proven to be a highly effective treatment in acute migraine attacks, but it is not available in many countries and contraindicated in patients with asthma or peptic ulcers.
