Bleomycin sulfate is an antineoplastic antibiotic isolated from Streptomyces verticillus. It is a mixture of glycopeptide antibiotics containing primarily Bleomycin A2 (~70%) and B2 (~30%). Bleomycin binds to DNA, inhibits DNA synthesis, and causes single strand scission of DNA in vivo and in vitro at specific base sequences.

Gentamicin is an antibiotic of the aminoglycoside group, is derived by the growth of Micromonospora purpurea, an actinomycete. Gentamicin is a complex of three different closely related aminoglycoside sulfates, Gentamicins C1, C2, and C1a. Gentamicin is a broad-spectrum antibiotic, but may cause ear and kidney damage. Gentamicin binds to the prokaryotic ribosome, inhibiting protein synthesis in susceptible bacteria. It is bactericidal in vitro against Gram-positive and Gram-negative bacteria. Adverse reactions include adverse renal effects, neurotoxicity (dizziness, vertigo, tinnitus, roaring in the ears, hearing loss, peripheral neuropathy or encephalopathy), respiratory depression, lethargy, confusion, depression, visual disturbances, etc.

Colistimethate is a methanesulfonate of polymyxin antibacterial colistin. Colistimethate is a nonactive prodrug. In aqueous solutions, colistimethate is hydrolyzed and forms a complex mixture of partially sulfomethylated derivatives and colistin. The antimicrobial activity of colistin is similar to that of polymyxin B and is restricted to gram-negative bacteria, including P aeruginosa, Acinetobacter species, Enterobacter-Klebsiella tribe, Escherichia coli, Salmonella and Shigella species, Citrobacter species, Yersinia pseudotuberculosis, Morganella morganii and Haemophilus influenzae. Colistin has also been shown to possess considerable in vitro activity against Stenotrophomonas maltophilia. Colistin and polymyxin B, however, do not have activity against Proteus, Providencia, Serratia species, Pseudomonas mallei, Burkholderia cepacia, Brucella species, most gram-positive bacteria, gram-negative cocci, anaerobes, fungi and parasites. Parenteral or nebulized colistimethate is indicated for the treatment of acute or chronic infections due to sensitive strains of certain gram-negative bacilli. It is particularly indicated when the infection is caused by sensitive strains of Pseudomonas aeruginosa.

Sodium lactate is primarily indicated as a source of bicarbonate for prevention or control of mild to moderate metabolic acidosis in patients with restricted oral intake whose oxidative processes are not seriously impaired. Sodium Lactate is most commonly associated with an E number of “E325” Sodium Lactate blends are commonly used in meat and poultry products to extend shelf life and increase food safety. They have a broad antimicrobial action and are effective at inhibiting most spoilage and pathogenic bacteria. In addition sodium lactate is used in cosmetics as a humectant, providing moisture.

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.

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.

Gonadorelin is a synthetic decapeptide prepared using solid phase peptide synthesis. GnRH is responsible for the release of follicle stimulating hormone and leutinizing hormone from the anterior pitutitary. In the pituitary GnRH stimulates synthesis and release of FSH and LH, a process that is controlled by the frequency and amplitude of GnRH pulses, as well as the feedback of androgens and estrogens. The pulsatility of GnRH secretion has been seen in all vertebrates, and it is necessary to ensure a correct reproductive function. Thus a single hormone, GnRH, controls a complex process of follicular growth, ovulation, and corpus luteum maintenance in the female, and spermatogenesis in the male. Its short half life requires infusion pumps for its clinical use. Gonadorelin is used for the treatment of amenorrhea, delayed puberty, and infertility the administration of gonadorelin is used to simulate the physiologic release of GnRH from the hypothalamus in treatment of delayed puberty, treatment of infertility caused by hypogonadotropic hypogonadism, and induction of ovulation in those women with hypothalamic amenorrhea. This results in increased levels of pituitary gonadotropins LH and FSH, which subsequently stimulate the gonads to produce reproductive steroids.
