A randomized double-blind, cross-over study using treatment periods of 12 weeks with a 2-week washout, comparing two long-acting formulations of propranolol ('Inderal' LA 160 mg daily and Half-'Inderal' LA 80 mg daily) was performed after a placebo run-in of 4 weeks on 51 patients. The study indicated that both long-acting formulations were significantly better than placebo in reducing the frequency of migraine attacks (p less than 0.01). After 12 weeks there was a significantly lower (p = 0.03) frequency of migraine attacks in patients on the higher dose formulation than in those on the lower dose formulation. There was no significant difference in the frequency of side effects produced by the two formulations.

In the treatment of angina pectoris a double-blind evaluation of verapamil (Cordilox) at two dose levels-namely, 80 mg thrice daily and 120 mg thrice daily-propranolol (Inderal) 100 mg thrice daily, and isosorbide dinitrate (Vascardin) 20 mg thrice daily has been made against a placebo. The assessment was based on relief from daily attacks of angina on effort and the response to a whole-body exercise test. We can find no statistically significant difference between the effects of verapamil (120 mg three times a day) and propranolol (100 mg three times a day) in the treatment of angina of effort. Both of these preparations are more effective than a placebo both in the reduction of daily attacks (P < 0.01) and in the prolongation of exercise test (P < 0.05). Isosorbide dinitrate (20 mg three times a day) appears to be no more effective than a placebo in the treatment of angina on effort, but 14 out of 32 patients experienced headache of such severity that even when the dose was reduced to 10 mg thrice daily this drug therapy had to be withdrawn. Both propranolol (100 mg three times a day) and verapamil (120 mg three times a day) had a significant lowering effect on the diastolic blood pressure as measured with the patient standing (P < 0.01).

The prophylactic effect of the 5-HT uptake inhibitor femoxetine was compared with propranolol (Frekven R) in a double-blind crossover trial of 6 months duration. Forty-nine patients commenced the trial. Twelve patients withdrew because of drug failure or failure to attend checkups (6), side effects (4) or other non-drug related causes (2). In the 37 patients who completed the trial there was no significant difference between propranolol 160 mg and femoxetine 400 mg with respect to the number of headache days or the number of migraine attacks during the last 2 months of each treatment, Propranolol, however, was superior to femoxetine when the headache index was used (P less than 0.05). The study has shown that partial depletion of thrombocyte 5-HT by a 5-HT uptake inhibitor does not lead to a marked improvement in all patients contrary to what might be expected from the 5-HT hypothesis of migraine. Nevertheless, due to the infrequent subjective side effects associated with femoxetine treatment it may be a valuable prophylactic drug to a subgroup of migraine patients.

The recent publication of drug formularies by third-party payers has serious implications for the practice of medicine. These formularies list the medications for which the consumer can be reimbursed by the third-party payer. The most restrictive of the five formularies I have received lists only two agents for the treatment of migraine headaches: Cafergot (at an incorrect dose of 1/100 mg) and Ergotrate which is no longer available. The most liberal of the formularies lists analgesics, Cafergot, Midrin, and Imitrex for the treatment of acute attacks, and as prophylactic agents, Inderal, Sansert, and analgesics (known to cause rebound headaches when used in this fashion in migraine patients). Abortive agents of proven value, such as DHE-45 and NSAIDs, and preventative medications, such as calcium channel blockers, tricyclic antidepressants, serotonin reuptake inhibitors, methylergonovine, and divalproex sodium, are not available. No one could quarrel with a goal of developing a cost-effective formulary. However, the authors of these formularies have clearly demonstrated their inability to provide even a current, accurate, and adequate formulary by existent standards of care in the treatment of migraine headache. While it is easy to criticize these formularies, it is more difficult to develop a comprehensive list that would satisfy the practitioners' need to provide relief for their patients with a minimum of side effects, and the needs of third-party payers (presumed) to provide quality care at the most economical level.
