Epilepsy - Pharmacology

4 important questions on Epilepsy - Pharmacology

What type of drugs are there against epilepsy (4)?

Main goal is reduce excitability

Na+  is going into the neuron => actiepotential
Ca+ for the neurotransmitter exocytosis.

Inhibition of glutamate is less likely to be used in the clinic.

Name different GABA mediated neural inhibitiors.

Enhance GABAA activation: Phenobarbital, benzodiazepines Inhibit GABA deaminase: Valproate, vigabatrin
Inhibit GABA re-uptake: Tiagabine

Besides the GABA, calcium, natrium and glutamate orientated drugs there are also other ones. Which ones? (4)

  • Carbonic Anhydrase Inhibitors => make neurons more hyperpolarised so that a neuron is less likely to depolarize
  • Hormones: progesteron
  • Cannabidiol.(CBD): use for Dravett syndrome works on a Na channel
  • Ketogenic diet: low carbohydrate => you use proteins instead of carbohydrates
  • Higher grades + faster learning
  • Never study anything twice
  • 100% sure, 100% understanding

How do carbonic anhydrase inhibition work?

More protons => pH reduced => increasing the K+ ions to leave

Lower seizure treshold

The question on the page originate from the summary of the following study material:

  • A unique study and practice tool
  • Never study anything twice again
  • Get the grades you hope for
  • 100% sure, 100% understanding
Remember faster, study better. Scientifically proven.
