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.

Calcium Cation Ca-45 is a calcium radioactive isotope which used for evaluation of calcium absorption and intracellular concentration in scientific research. There are several calcium radionuclides available, including 41Ca, 45Ca, and 47Ca. For practical reasons, 45Ca is the most commonly used calcium radionuclide for biological investigations.

Calcium Cation Ca-47 is a rare calcium radioactive isotope which used in orthopaedics for bone formation evaluation. Calcium-47 has a half-life of about five days, which is long enough for numerous biological investigations and short enough to ensure that the person subjected to the investigation is not under prolonged irradiation. It emits gamma rays in addition to beta rays, and since the gamma rays are capable of penetrating many centimeters of tissue, determination of calcium-47 in the body is possible by external measurements. Unfortunately, calcium-47 is difficult to produce and did not use in routine medical practice

1,1,1-trichloroethane (methyl chloroform) is a colorless liquid or vapour with a sharp sweet smell. It dissolves in water and other chemicals and easily evaporates into the air. TCE is non-flammable. Trichloroethane is used as a solvent and degreasing agent in industry. It is an ingredient in consumer products such as household cleaners, glues, and aerosol sprays. Methyl chloroform is also used as a chemical intermediate in the production of vinylidene chloride. It was formerly used as a food and grain fumigant. Excessive absorption of this substance through the lungs or gastrointestinal tract produces central nervous system (CNS) depression proportional to the amount absorbed. Mild liver and kidney dysfunction may occur transiently following recovery from CNS depression. The consumption of trichloroethane has been banned by the 1987 Montreal Protocol because of its ozone-depleting potential.

Dibromsalan (4',5-dibromosalicylanilide) is a disinfectant. Dibromsalan is a halogenated phenol derivative chemically related to bithionol and tetrachlorosalicylanilide (TCSA). It has antimicrobial properties. It was an ingredient of some commercial soaps. It was withdrawn from the market for reasons of safety. Dibromsalan was shown to cause photodermatitis.

Penicillin G, also known as benzylpenicillin, is a penicillin derivative commonly used in the form of its sodium or potassium salts in the treatment of a variety of infections. It is effective against most gram-positive bacteria and against gram-negative cocci. It is administered intravenously or intramuscularly due to poor oral absorption. Penicillin G may also be used in some cases as prophylaxis against susceptible organisms. Microbiology Penicillin G is bactericidal against penicillin-susceptible microorganisms during the stage of active multiplication. It acts by inhibiting biosynthesis of cell-wall mucopeptide. It is not active against the penicillinase-producing bacteria, which include many strains of staphylococci. Penicillin G is highly active in vitro against staphylococci (except penicillinase-producing strains), streptococci (groups A, B, C, G, H, L and M), pneumococci and Neisseria meningitidis. Other organisms susceptible in vitro to penicillin G are Neisseria gonorrhoeae, Corynebacterium diphtheriae, Bacillus anthracis, clostridia, Actinomyces species, Spirillum minus, Streptobacillus monillformis, Listeria monocytogenes, and leptospira; Treponema pallidum is extremely susceptible. Adverse effects can include hypersensitivity reactions including urticaria, fever, joint pains, rashes, angioedema, anaphylaxis, serum sickness-like reaction.

Olaflur (amine fluoride 297, trade name elmex gel) is a fluoride-containing substance that is an ingredient of toothpastes and solutions for the prevention of dental caries. Especially in combination with dectaflur, it is also used in the form of gels for the treatment of early stages of caries, sensitive teeth, and by dentists for the refluoridation of damaged tooth enamel. Olaflur is a salt consisting of an alkyl ammonium cation and fluoride as the counterion. With a long lipophilic hydrocarbon chain, the cation has surfactant properties. It forms a film layer on the surface of teeth, which facilitates incorporation of fluoride into the enamel. The top layers of the enamel's primary mineral, hydroxylapatite, are converted into the more robust fluorapatite. The fluoridation reaches only a depth of a few nanometres, which has raised doubts whether the mechanism really relies on the formation of fluorapatite.
