Clinical Summary

A serotonin agonist that acts selectively at 5HT1 receptors. It is used in the treatment of MIGRAINE DISORDERS.

Therapeutic Applications

Sumatriptan is used to treat migraines and cluster headaches. It helps to relieve pain and other symptoms of migraines/headaches including sensitivity to light or sound, nausea, and vomiting. Prompt treatment allows you to get back to your normal routine and may decrease your need for other pain medications. It does not prevent future migraines/headaches or reduce how often you may get a headache. Sumatriptan belongs to a group of drugs called triptans. It affects a certain natural chemical (serotonin) that constricts blood vessels in the brain. It may also block other pain pathways in the brain.

Clinical Summary

A sulfamate-substituted fructose analog that was originally identified as a hypoglycemic agent. It is used for the treatment of EPILEPSY and MIGRAINE DISORDERS, and may also promote weight loss.

Therapeutic Applications

Topiramate is used alone or with other medications to prevent and control seizures (epilepsy). This medication is also used to prevent migraine headaches and decrease how often you get them. Topiramate will not treat a migraine headache once it occurs. If you get a migraine headache, treat it as directed by your doctor (such as by taking pain medication, lying down in a dark room). Topiramate is known as an anticonvulsant or antiepileptic drug.

Dataset Methodology & CMS Source Information

This analytical profile maps public infrastructure records sourced directly from official **Centers for Medicare & Medicaid Services (CMS)** public data releases. The statistics above track documented pharmaceutical treatment trends assigned to beneficiaries specifically under federal public programs. Evaluating the prescriptive footprints of clinical practitioners like MICHAEL L. KIEKHAEFER MD provides transparency into local medical care patterns within Stockton, CA.

Key Learning Objectives for this Profile:

  • Prescribing Frequencies: Track and evaluate the volume metrics of specific brand-name and generic medical formulas chosen by this provider over time.
  • Clinical Focus Areas: Identify how the provider distributes therapeutic selections across medical care options to gain insight into their true day-to-day **Neurology** practice concentrations.
  • Program Cost Awareness: Review the calculated total systemic drug costs and raw transactional volumes linked to these orders to better anticipate network insurance coverage structures.
  • Patient-Centered Evaluation: Cross-reference localized regional care comparisons to align practitioner habits directly with your proactive health maintenance goals.

Data Scope Exclusion & Limitations: The data elements presented above explicitly reflect prescription orders processed for Medicare beneficiaries during the year 2023. This informational profile does not aggregate prescription data for individuals utilizing private commercial health plans, state Medicaid coverage, or self-pay options.
