Q

True or False? Gabapentin and pregabalin work on GABA in the brain

A

False - despite their names they have no association with GABA, they work on the 𝜶2ẟ subunit of presynaptic N and P/Q voltage-sensitive calcium channel to block release of glutamate when neurotransmission is excessive

Q

What happens with SNRIs and β1 receptors when initially starting the medication?

Q

What is the MOA of benzodiazepines? (3)

A
  1. Bind to the benzodiazepine receptors on the GABA neuron
  2. Leads to an increase in the frequency of opening of the chloride channels by increasing binding affinity for the endogenous ligand GABA
  3. The shift in chloride ions results in hyperpolarization (a less excitable state) and stabilization
