Drug Name Augmentin

Ca2+ antagonists reduce depolarizing inward Ca2+ currents, while K+-channel activators promote outward (hyperpolarizing) K+ currents. Organic nitrovasodilators give rise to NO, an endogenous activator of guanylate cyclase. Individual vasodilators. Nitrates Ca2+-antagonists. ?1- antagonists, ACE-inhibitors, AT1- antagonists; and sodium nitroprusside are discussed elsewhere.
Altered activity of transport systems affects cell function (e.g., cardiac glycosides; loop diuretics; calcium-antagonists). Drugs may also directly interfere with intracellular metabolic processes, for instance by inhibiting (phosphodiesterase inhibitors) or activating (organic nitrates) an enzyme.

 

I. Drugs for Lowering Acid Concentration Ia. Acid neutralization. H+-binding groups such as CO3 2–, HCO3 – or OH–, together with their counter ions, are contained in antacid drugs. Neutralization reactions occurring after intake of CaCO3 and NaHCO3, respectively, are shown in (A) at left.
It is a suitable substitute in penicillin allergy or resistance. Azithromycin, clarithromycin, and roxithromycin are derivatives with greater acid stability and better bioavailability. The compounds mentioned are the most important members of the macrolide antibiotic group, which includes josamycin and spiramycin.
