Calcium lactate is the salt that consists of two lactate anions for each calcium cation (Ca2+); this salt is used as a calcium supplement to treat hypocalcemia. However, as a source of free calcium, this salt is less convenient than calcium citrate. Calcium lactate inhalation powder also called as PUR118 participated in phase I clinical trials to determine whether this formulation was safe and tolerable in a population of subjects with Cystic Fibrosis (CF). PUR118 also was used in another clinical trials to evaluate its effect on ozone-induced airway Inflammation in healthy normal volunteers in case of Chronic Obstructive Pulmonary Disease (COPD). The obtained results revealed that PUR118 reduced the severity of acute exacerbations in COPD and CF and had the beneficial impacts on mortality, morbidity, and quality of life in affected individuals. However, both studies were discontinued.

Potassium citrate is indicated for the management of renal tubular acidosis with calcium stones, hypocitraturic calcium oxalate nephrolithiasis of any etiology, uric acid lithiasis with or without calcium stones. WhenPotassium citrate is given orally, the metabolism of absorbed citrate produces an alkaline load. The induced alkaline load in turn increases urinary pH and raises urinary citrate by augmenting citrate clearance without measurably altering ultrafilterable serum citrate. Thus, potassium citrate therapy appears to increase urinary citrate principally by modifying the renal handling of citrate, rather than by increasing the filtered load of citrate. Potassium citrate is used as a food additive (E 332) to regulate acidity.

Epinephrine is a sympathomimetic catecholamine. It acts as a naturally occurring agonist at both alpha and beta-adrenergic receptors. Three pharmacologic types have been identified: alpha 1-, alpha 2-, and beta-adrenergic receptors. Each of these has three subtypes, characterized by both structural and functional differences. The alpha 2 and beta receptors are coupled negatively and positively, respectively, to adenylyl cyclase via Gi or Gs regulatory proteins, and the alpha 1 receptors modulate phospholipase C via the Go protein. Subtype expression is regulated at the level of the gene, the mRNA, and the protein through various transcriptional and postsynthetic mechanisms. Through its action on alpha-adrenergic receptors, epinephrine lessens the vasodilation and increased vascular permeability that occurs during anaphylaxis, which can lead to loss of intravascular fluid volume and hypotension. Through its action on beta-adrenergic receptors, epinephrine causes bronchial smooth muscle relaxation and helps alleviate bronchospasm, wheezing and dyspnea that may occur during anaphylaxis. Epinephrine also alleviates pruritus, urticaria, and angioedema and may relieve gastrointestinal and genitourinary symptoms associated with anaphylaxis because of its relaxer effects on the smooth muscle of the stomach, intestine, uterus and urinary bladder. Epinephrine increases glycogenolysis, reduces glucose up take by tissues, and inhibits insulin release in the pancreas, resulting in hyperglycemia and increased blood lactic acid.

The immunosugar N-9-methoxynonyldeoxynojirimycin (SP-187, UV-4B) is an inhibitor of both glucosidases I and II. In preclinical studies, it displayed inhibition of dengue and influenza virus infection. The compound developed by Emergent BioSolutions and evaluated in phase 1 clinical trials on healthy subjects.
