[Experimental substantiation for the application of calcium channel blockers in vibration disease]
Abstract:
The mechanism of vibroprotective action for nifedipine, a calcium channel blocker, was studied in myocardiocytes of rabbits. The shifts in functional activity of mitochondria were registered after prolonged common vibration of rabbits during 56 days (1 h every day). Nifedipine (7.5 mg/kg per os) activated NAD-depended site of respiratory chain and prevented hyperactivation of succunate-depended breath. The positive energotropic action of nifedipine was accompanied by stability of histomorphological cytoarchitechture of rabbit myocardium, wich was disturbed in nontreated animals. It is suggested that nifedipine protects myocardium from prolonged action of vibration.

Antiepileptic Drugs: Calcium Channel Blockers
Calcium channel blockers exert their antiepileptic effects by targeting T-type calcium channels, which are integral to transmitting nerve signals in the central nervous system. These channels allow the passage of calcium ions, which are vital for neuronal communication. By inhibiting T-type calcium channels, calcium channel blockers effectively reduce the release of neurotransmitters and...
