Cơ Chế Tác Dụng :
The administration of quinidine derivatives helps to observe various skin and mucosal reactions. A papulopurpuric eruption in a patient (without thrombopenia) can be developed who is taking quinidine phenylethyl barbiturate intermittently and at reintroduction.(PMID: 9739909)
Barbiturates work by binding to the GABAA receptor at either the alpha or the beta sub unit. These are binding sites that are distinct from GABA itself and also distinct from the benzodiazepine binding site. Like benzodiazepines, barbiturates potentiate the effect of GABA at this receptor. This GABAA receptor binding decreases input resistance, depresses burst and tonic firing, especially in ventrobasal and intralaminar neurons, while at the same time increasing burst duration and mean conductance at individual chloride channels; this increases both the amplitude and decay time of inhibitory postsynaptic currents. In addition to this GABA-ergic effect, barbiturates also block the AMPA receptor, a subtype of glutamate receptor. Glutamate is the principal excitatory neurotransmitter in the mammalian CNS.
