Metoprolol is a beta blocker, or an antagonist of the β-adrenergic receptors. It is specifically a selective antagonist of the β 1-adrenergic receptor and has no intrinsic sympathomimetic activity. [37] Metoprolol exerts its effects by blocking the action of certain neurotransmitters, specifically adrenaline and noradrenaline.
The H 2 receptor antagonists are a class of drugs used to block the action of histamine on parietal cells in the stomach, decreasing the production of acid by these cells. H 2 antagonists are used in the treatment of dyspepsia, although they have been surpassed in popularity by the more effective [1] proton pump inhibitors.
Metabolic acidosis can lead to acidemia, which is defined as arterial blood pH that is lower than 7.35. [6] Acidemia and acidosis are not mutually exclusive – pH and hydrogen ion concentrations also depend on the coexistence of other acid-base disorders; therefore, pH levels in people with metabolic acidosis can range from low to high.
Alkaline tide (mal del puerco) refers to a condition, normally encountered after eating a meal, where during the production of hydrochloric acid by the parietal cells in the stomach, the parietal cells secrete bicarbonate ions across their basolateral membranes and into the blood, causing a temporary increase in blood pH.
