Tetracaine HCl is a potent local anaesthetic and a channel function allosteric inhibitor.Target: Calcium ChannelTetracaine hydrochloride is a calcium channel protein inhibitor and blocks voltage-sensitive release of Ca2+ from sarcoplasmic reticulum. Tetracaine is a potent local anesthetic of the ester group. It is mainly used topically in ophthalmology and as an antipruritic, and it has been used in spinal anesthesia. Tetracaine is used to alter the function of calcium release channels (ryanodine receptors) that control the release of calcium from intracellular stores. Tetracaine is an allosteric blocker of channel function. At low concentrations, tetracaine causes an initial inhibition of spontaneous calcium release events, while at high concentrations, tetracaine blocks release completely [1, 2].

Lacidipine protects HKCs from apoptosis induced by ATP depletion and recovery by modulating the caspase-3 pathway. Lacidipine can be used in studies of hypertension, atherosclerosis and acute kidney injury (AKI)[2][3].
