Venous pharmacotherapy is a subject which, up to now, has not been submitted to rigorous scientific investigation as we currently lack in vivo observation methods. We can oppose direct actions stemming from sympathic stimulation and tissular mediators to the indirect actions of the substances which affect the arteriolar circulation or arterio-venous anastomoses. Anthocyanosides are amongst the most important of all the drugs acting on the permeability of the membrane. Dihydroergotamine, which has revived old controversies about the vegetative innervation of vein walls, has proved to have an increasing effect on venous pressure in clinostatism. We have ourselves witnessed this venotonic action of subjects in the supine position. In an upright position there have not been any reactions of hypertension, perhaps because of the hypertonic effect obtained naturally from the bard receptors which prevail on the pharmacological effect.

I have discussed the pharmacokinetics, efficacies, and side effects of the various nonnarcotic drugs available for the treatment of patients who have headache. Sumatriptan, the newest one, is expensive but may be cost-effective for those who have failed traditional migraine treatment, who visit the ER frequently, who have potential for drug abuse, or who have to miss time from school or work due to the headache. Studies are in progress to compare sumatriptan with other available drugs such as DHE-45 and to determine its possible role in the prophylaxis of migraine. A new 5-HT1D receptor agonist with more efficacy and fewer side effects may be developed in the future. When sumatriptan and DHE-45 are contraindicated due to hypertension or coronary artery disease, other drugs such as metoclopramide, ketorolac, and butorphanol can be used as alternatives.
