S and levels of proof are summarised in Table two. Even so, the option of treatment have to also be created taking into account the variability in individual response. Within this regard, in a prospective study in CH patients, older age emerged as a predictor for decreased order AZD0156 response to the triptans, whereas nausea, vomiting and restlessness predicted a poor response to oxygen [144]. Other significant variables would be the presence of clinical comorbidities andthe patient’s preferred route of selfadministration of a offered therapy. Preventive Remedy Preventive remedy is a basic part of the management of active CH. Different drugs and approaches for acute CH treatment, like the triptans and oxygen, happen to be found to be safe and nicely tolerated even when employed regularly or in prolonged treatments. Hence, in ECH, a symptomatic remedy alone might be suitable for active phases of short duration (mini-clusters). Even so, there is certainly no proof that symptomatic agents can influence the organic onset and evolution of standard cluster periods. For this312 Present Neuropharmacology, 2015, Vol. 13, No.Costa et al.Table 2.DrugLevels of recommendation for symptomatic (a) and preventive (b) therapy of cluster headache (CH) [8,145].DosageLevel of RecommendationComments(a) Symptomatic treatments Sumatriptan Sumatriptan Zolmitriptan Oxygen inhalation Octreotide LidocaineDrug6 mg s.c 20 mg nasal spray 50 mg nasal spray 7-10 lmin for 15 min 100 s.c. 1 ml (4-10 ) nasal sprayDosage (each day)A A A A B BLevel of RecommendationA B C B C CLess productive than lithium in chronic CH Elective efficacy in chronic CH Comments Slower onset of action than sumatriptan s.c.

On the other hand, although the true effectiveness of a offered treatment can be PubMed ID:http://www.ncbi.nlm.nih.gov/pubmed/21338362 ascertained in chronic CH, it’s far more tough to evaluate within the episodic form, because active periods can generally subside spontaneously. CH prophylaxis must be governed by a couple of general guidelines [8, 145]: 1) preventive treatment must start off early in the active phase, and continue for no less than two weeks after the disappearance of attacks; 2) the treatment ought to be decreased progressively and eventually suspended, and when the attacks reappear, dosages has to be improved back to therapeutic levels; 3) treatment should be re-started in the onset of a subsequent active period; 4) inside the selection from the remedy, several aspects need to be taken into account, such as the patient’s age and way of life (e.g. alcohol intake ought to be avoided through a cluster period), the expected duration on the cluster period, the kind of CH (episodic or chronic),the response to previous remedies, any reported side effec.
