The methods used presently for abortion of the attacks of migraine and cluster headache are not fully satisfactory which causes that the search for new therapies is continuing. Although the mechanism of migraine attacks remains unexplained, it is thought that an important role in it is played by serotonin receptors, vasodilation in certain regions and opening of arteriovenous communications in the head. Sumatriptan is an agonist of 5-HT1 -like receptors and exerts a selective vasoconstricting effect on the arteries of the head, particularly in the rami of the carotid artery. In 1988 the first reports appeared on the effectiveness of the drug in migraine attacks. In the following years extensive, multicentre and international studies of the drug were carried out on over 600 healthy volunteers and nearly 6000 patients with migraine. The studies demonstrated that Sumatriptan was effective in abortion of migraine attacks. After oral administration of 100 mg or subcutaneous injection of 6 mg in nearly 70% of cases the attack regressed or was greatly alleviated, similarly as other symptoms accompanying the headache such as photophobia, nausea, vomiting. Studies were undertaken also on the effectiveness of Sumatriptan in emergency treatment of cluster headache, and good results were again achieved. The tolerance of the drug is good, although in some cases side effects develop, usually transient and mild, among them tingling, feeling of pressure, heat or heaviness of the head or chest, taste change and burning sensation at the site of injection. Sumatriptan, similarly as all novel drugs, requires caution in its use, particularly in patients with coronary heart disease and hypertension, and also in old patients. As yet, the use of the drug in paediatric migraine or in pregnancy is not recommended.

Two hundred patients clinically certified as suffering from anxiety state were investigated with a view to understanding the clinical manifestation of the condition in Nigeria. We found that 67 symptoms were manifested by those patients, but only 15 symptoms were presented by about 10% of the sample. These common symptoms were: frequent headaches, difficulty in falling asleep, flushing, difficulty in concentrating, rapid or irregular heart beating, weakness, hot flashes, dizziness, feeling of something crawling in the head, heaviness of the head, nervousness, poor appetite, poor sight, nightmares, and chest pain. The five major precipitating factors were physical ailments, studying and examinations, use of drugs, psychological phenomona, pregnancy and childbirth, in decreasing order of magnitude. The most vulnerable age group was between 18 and 23 years old. The first born children account for the highest number of anxiety patients, but as the number of siblings increases, the vulnerability of the last-born increases. Anxiety neurosis as seen here is predominantly a problem of single males and females with secondary school education.
