WebNifedipine and nicardipine are both calcium channel inhibitors, used off-label as tocolytics in preterm labour. Their use is related to their relaxing effects on uterin muscle by L-type voltage dependent calcium channels blockade. This article describes pharmacological effects, pharmacokinetics properties and tolerance of these drugs.

WebCalcium-channel blockers are a large and diverse group. The full list of potential interactions for each drug is beyond the scope of this topic. For complete, and drug-specific information on interactions, refer to the British National Formulary (BNF) or the manufacturers' information in the electronic medicines compendium (emc). [ BNF, 2024 ] WebMost Na +, K +, Ca 2+ and some Cl - channels are gated by voltage, whereas others (such as some K + and Cl - channels, TRP channels, ryanodine receptors and IP 3 receptors) are relatively voltage-insensitive and are gated by second messengers and other intracellular and/or extracellular mediators.
