title: [Clinical evaluation of the efficacy of the paracetamol and caffeine combination in the treatment of tension headache].
abstract: Tension type headache in both its forms, episodic and chronic, is the most common type of headache experienced by the population. The headache attack or the prevention of new crises may be treated with pharmacological as well as non-pharmacological measures. This study included 5,490 patients from out-patient clinics and medical offices covering various regions of Brazil. Approximately 95% of the subjects had episodic tension type headache, while 5% had chronic tension type headache. The majority of the patients presented with crisis of moderate intensity (62.19%). In 5,419 patients a tension type headache crisis was treated with acetaminophen 1000 mg and caffeine 130 mg. In 93.98%, onset of relief occurred within 2 hours of taking the medication. In 77.61%, complete reversion of the crisis occurred within 2 hours. Good/excellent efficacy ratings were achieved in 61.93%/37.80% of the cases according to the physician's assessment and in 48.51%/40.29% according to the patients' assessment. Adverse events, commonly gastrointestinal manifestations, were reported by 5.57% of the patients. This is a Brazilian study of the efficacy and safety of the combined use of acetaminophen-caffeine for the treatment of tension type headache.
