WebRetigabine is a drug for treating epilepsy. It has been approved for marketing in the UK, Germany, and Denmark. Studies have confirmed that the role of Retigabine is related to the voltage-gated potassium ion channel (KCNQs), wherein its main mechanism of action is to regulate M-type potassium currents by acting on KCNQ2/3 channels. WebThe mechanism is a little bit different from the formation of a tosylate, so let's go ahead and look and see what happens. At first, the triethylamine is going to function as a base and take this proton right here, so these …
