Thus, doses from 240 mg to 960 mg are recommended depending on effect and adverse events.In the following commentary, we will shortly review the clinical pharmacology of verapamil. The effect of verapamil in cluster headache most likely takes place in the hypothalamus.Verapamil is an L‐type calcium channel blocker but it is also a blocker of other calcium channels (T‐, P‐, and possibly N‐ and Q‐type CaIt was recently stated that current therapeutic actions of the existing available CaThe dose of verapamil needed in the preventive treatment of cluster headache patients varies considerably. It is used by mouth, by injection, or as a skin patch. High‐dose verapamil (360‐720 mg) is, however, currently the mainstay in the prophylactic treatment of cluster headache.

Thus, a study found that in individuals with hypertension systolic blood pressure response to verapamil ranged from a 33 mmHg decline to a 4 mmHg increase, with an average 12 mmHg decrease.In the very large (n = 22,576) INVEST study on hypertension in patients with coronary artery disease, the starting dose of verapamil was 240 mg as a slow release formulation and the maximum dose was 180 mg twice daily.The “mean neurological dose” is thus approximately twice “the mean cardiovascular dose.”The difference in mean doses could be explained by the fact that the cardiovascular effects are directly related to blood levels of verapamil, whereas the “neurological” effect (effect on cluster headache) takes place across the blood–brain barrier where P‐gp restricts the access of verapamil to the brain.In patients without previous experience with verapamil, it is not possible to predict the optimal dose of verapamil.
