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.

Tetraglycine hydroperiodide is an iodine-containing chemical, used for water purification. Tetraglycine hydroperiodide is marketed in tablets; each tablet effectively disinfects 1 liter of clear water or 0.5 liter of tainted water by releasing approximately 8 mg free iodine. It requires approximately 30 minutes to inactivate target microorganisms and make water bacteriologically suitable for drinking. To remove iodine taste, a vitamin C pill is added to the kit.

Magnesium diamide is used as a chemical intermediate. Magnesium diamide is spontaneously combustible. It is toxic by inhalation. Skin or eye contact may cause severe burns.

Cetrimide is a quaternary ammonium compound. Cetrimide was first introduced as a combined cleanser and skin antiseptic by Barnes (1942). Cetrimide combines excellent detergent properties and minimal toxicity with a useful antiseptic action. Cetrimide affects membrane permeability allowing ‘leaking’ of essential cell constituents leading to cell death. This medication is a skin antiseptic and disinfectant prescribed for seborrhoeic dermatitis and wound cleansing. The cream has a bactericidal activity against gram-positive bacteria and incompatible with soaps and other anionic surfactants.
