Devapamil (Devapamilo) is a phenylalkylamine that blocks L-type calcium currents from the inner side of membrane cells in a use-dependent manner.

Oxodipine, a dihydropyridine-type calcium antagonist, inhibited KCl-induced aortic contraction in rabbits and reduced cardiac force in less potent rat ventricular test-paper contractions. In rat cultured neonatal ventricular myocytes, Oxodipine reduced L-type Ca currents (I) with an IC of 0.24 μM, and against T-type Ca currents (I) with an IC of 0.41 μM. Oxodipine causes constipation in mice and gingival hyperplasia in dogs.

Quinidine hydrochloride monohydrate is an optical isomer of quinine, extracted from the bark of the Cinchona tree and similar plant species. It prolongs cellular action potential and decreases automaticity. This alkaloid dampens the excitability of cardiac and skeletal muscles by blocking sodium and potassium currents across cellular membranes. Quinidine also blocks muscarinic and alpha-adrenergic neurotransmission.

Zonisamide (AD 810), a sulfonamide anticonvulsant, is approved for use as an adjunctive treatment in adults with partial-onset seizures. It may inhibit a carbonic anhydrase although this is not one of the main mechanisms of action. Zonisamide may act by blocking repetitive firing of voltage-gated sodium channels results in a reduction of T-type calcium channel currents, or by binding allosterically to GABA receptors. This latter action may lower the uptake of the inhibitory neurotransmitter GABA while increasing the uptake of the excitatory neurotransmitter glutamate.

1-Octanol, a saturated fatty alcohol, functions as an inhibitor of T-type calcium channels (T-channels), showing an inhibitory concentration (IC50) of 4 μM for native T-currents[1]. Additionally, 1-Octanol is recognized for its potential as a biofuel, possessing diesel-like properties[2].

Amiodarone hydrochloride is an anti-anginal agent and a class III antiarrhythmic drug that inhibits potassium channels (including wild-type hERG channels and their tail currents, with an IC₅₀ of approximately 45 nM) as well as voltage-gated sodium channels. This leads to prolonged action potential duration in ventricular and atrial myocytes, resulting in reduced heart rate and vascular resistance. It activates ERK1/2 and p38 MAPK signaling pathways in fibroblasts, promoting cell proliferation and myofibroblast differentiation. Amiodarone hydrochloride is widely used in the study of supraventricular and ventricular arrhythmias and can also be used to establish pulmonary fibrosis animal models.
