Nifedipine (Procardia) is a dihydropyridine calcium channel blocking agent. Nifedipine inhibits the transmembrane influx of extracellular calcium ions into myocardial and vascular smooth muscle cells, causing dilatation of the main coronary and systemic arteries and decreasing myocardial contractility. This agent also inhibits the drug efflux pump P-glycoprotein which is overexpressed in some multi-drug resistant tumors and may improve the efficacy of some antineoplastic agents.

Riboflavine phosphate (Flavin mononucleotide) is a derivative of Riboflavin. Riboflavin phosphate can be used to study keratoconus, corneal dilatation, and irregular astigmatism. Riboflavine phosphate is an efficient and economical recycler of NAD+.

Valethamate bromide (Resitan) is an anticholinergic agent that has antispasmodic effects and inhibits glandular secretion.

Clocoumarol is an anticoagulant that prevents blood clotting. It also can inhibit the dilatation of the spleen and the congestion of lymph nodes.

Chloracyzine can produce a decrease in myocardial oxygen consumption accompanied by a reduction in coronary blood flow preceded by transient coronary dilatation. It produced an insignificant increase in arterial pressure; heart rate increased slightly in
