While nonmyelinating Schwann cells are the origin of neurofibromas, the mutations that make them susceptible to this transformation occur in Schwann cell precursors during early nerve development. Mutated nonmyelinating Schwann cells do not form normal Remak bundles. Instead, they fail to properly surround and segregate target axons. It is unknown at this time why, if both types of Schwann cells exhibit bilallelic inactivation of the NF1 gene, only the nonmyelinating variety give rise to neurofibromas. Loss of tumor suppressor function
Neurofibromas arise from nonmyelinating Schwann cells that only express the inactive version of the NF1 gene, which leads to a complete loss of expression of functional neurofibromin. While one defective allele may be inherited, loss of heterozygosity (LOH) must occur before a neurofibroma can form; this is called the two-hit hypothesis. This LOH happens by the same mechanisms, such as oxidative DNA damage, that causes mutations in other cells. Once a nonmyelinating Schwann cell has suffered inactivation of its NF1 genes, it begins to proliferate rapidly. This condition is called hyperplasia, which is cell growth beyond what is normally seen. However, despite increased numbers of nonmyelinating Schwann cells, there is no neurofibroma yet. In order for the neurofibroma to develop, cells that are heterozygous for the NF1 gene must be recruited to the site. It has been hypothesized that the proliferating nonmyelinating Schwann cells secrete chemoattractants such as the KIT ligand, and angiogenic factors such as the heparin-binding growth factor midkine.
Zolmitriptan, sold under the brand name Zomig among others, is a triptan used in the acute treatment of migraine attacks with or without aura and cluster headaches. It is a selective serotonin receptor agonist of the 1B and 1D subtypes. It was patented in 1990 and approved for medical use in 1997. Medical uses
Zolmitriptan is used for the acute treatment of migraines with or without aura in adults. Zolmitriptan is not intended for the prophylactic therapy of migraine or for use in the management of hemiplegic or basilar migraine. Zolmitriptan is available as a swallowable tablet, an oral disintegrating tablet, and a nasal spray, in doses of 2.5 and 5 mg.  People who get migraines from aspartame should not use the disintegrating tablet (Zomig ZMT), which contains aspartame.A 2014 Cochrane review has shown that zolmitriptan 5 mg nasal spray was significantly more effective than the 5 mg oral tablet.According to a study of healthy volunteers, food intake seems to have no significant effect on the effectiveness of Zolmitriptan in both men and women.Off-label Uses:

Acute treatment of cluster headaches—Level A recommendation from the American Academy of Neurology
Acute treatment of menstrual migraine

Adverse reactions
As for cardiovascular side effects, zolmitriptan can increase systolic blood pressure in the elderly and increase diastolic blood pressure in both the elderly and young people. Additionally, there is the side effect of a dose-related increase in sedation.
