Ceftizoxime is a semisynthetic cephalosporin antibiotic, which can be administered intravenously or intramuscularly. It was sold under brand name, cefizox, but was removed from the US Market in 2007. Cefizox was used to treat different infections, such as lower respiratory tract infections caused by Klebsiella spp.; Proteus mirabilis; Escherichia coli; Haemophilus influenza; urinary tract Infections caused by Staphylococcus aureus (penicillinase¬ and nonpenicillinase¬producing); Escherichia coli; Pseudomonas spp. Also for treatment of gonorrhea including uncomplicated cervical and urethral gonorrhea caused by Neisseria gonorrhoeae; pelvic inflammatory disease caused by Neisseria gonorrhoeae, Escherichia coli or Streptococcus agalactiae; meningitis caused by Haemophilus influenza. In addition, some others infections. Cefizox has also been used successfully in the treatment of a limited number of pediatric and adult cases of meningitis caused by Streptococcus pneumoniae. Infections caused by aerobic gram ¬negative and by mixtures of organisms resistant to other cephalosporins, aminoglycosides, or penicillins have responded to treatment with Cefizox. The bactericidal action of ceftizoxime results from inhibition of the third and last stage of bacterial cell wall synthesis. Bacterial cell wall autolytic enzymes such as autolysins then mediate cell lysis; it is possible that ceftizoxime interferes with an autolysin inhibitor. Ceftizoxime is highly resistant to a broad spectrum of beta -lactamases (penicillinase and cephalosporinase), including Richmond types II, III, TEM, IV, produced by both aerobic and anaerobic gram - positive and gram - negative organisms and I.

Bayer developed MEZLOCILLIN (previously known as BAYPEN); it is a semisynthetic ampicillin-derived penicillin. Mezlocillin is a penicillin beta-lactam antibiotic used in the treatment of bacterial infections caused by susceptible, usually gram-positive, organisms. The bactericidal activity of mezlocillin results from the inhibition of cell wall synthesis and is mediated through mezlocillin binding to penicillin binding proteins (PBPs). Mezlocillin is stable against hydrolysis by a variety of beta-lactamases, including penicillinases and cephalosporinases and extended spectrum beta-lactamases. Mezlocillin was poorly absorbed orally and was given either intramuscularly or intravenously. This drug was discontinued in the U.S.

Cyanocobalamin Co 57 is a manufactured form of radiolabeled vitamin B indicated as an adjunct in diagnosing intestinal cyanocobalamin malabsorption syndromes due to lack of intrinsic factor (IF) or other defects in intestinal absorption (e.g., blind loop syndrome and diverticulitis, celiac disease, Crohn's disease, lesions in the small intestine, severe pancreatitis, tropical sprue).

Polythiazide is a thiazide diuretic with actions and uses similar to those of hydrochlorothiazide. Polythiazide under brand name Rense is indicated as adjunctive therapy in edema associated with congestive heart failure, hepatic cirrhosis, and corticosteroid and estrogen therapy. Renese is indicated in the management of hypertension either as the sole therapeutic agent or to enhance the effectiveness of other antihypertensive drugs in the more severe forms of hypertension. The mechanism of action results in an interference with the renal tubular mechanism of electrolyte reabsorption. At maximal therapeutic dosage, all thiazides are approximately equal in their diuretic potency. The mechanism whereby thiazides function in the control of hypertension is unknown, but as a diuretic, polythiazide inhibits active chloride reabsorption at the early distal tubule via the thiazide-sensitive Na-Cl cotransporter (TSC), resulting in an increase in the excretion of sodium, chloride, and water. Thiazides like polythiazide also inhibit sodium ion transport across the renal tubular epithelium through binding to the thiazide sensitive sodium-chloride transporter. This results in an increase in potassium excretion via the sodium-potassium exchange mechanism. The antihypertensive mechanism of polythiazide may be mediated through its action on carbonic anhydrases in the smooth muscle or through its action on the large-conductance calcium-activated potassium (KCa) channel, also found in the smooth muscle.

Tyrosine (L-form) is a non-essential amino acid, which is primarily required for the protein synthesis. This amino acid is the precursor of dopamine, norepinephrine, and epinephrine; therefore the lower concentration of tyrosine could be a peripheral marker of the hyperdopaminergic condition hypothesized to explain psychosis. Tyrosine supplements can improve cognition, increase energy, reduce anxiety, reduce depression, reduce levels of pain.

Dimethyl succinate is the inactive analog of dimethyl fumarate. Dimethyl succinate has a pleasant, ethereal, winey odor and a fruity, winey, and burning flavor. It is used in foods as a flavoring ingredient. Dimethyl succinate was found at increased concentrations in the culture medium of the lung cancer cell line A549 and in the urine of mice implanted with A549 cells. Dimethyl succinate could be used to prolong the insulinotropic action of GLP-1 in the treatment of type-2 diabetes and it may represent a novel therapeutic approach in endotoxemia and multiple-organ failure.

Gestodene (17alpa-ethynyl-13beta-ethyl-17beta-hydroxy-4,15-gonadien-3-one) is the most potent synthetic progestin currently available and it is widely used as a fertility regulating agent in a number of contraceptive formulations because of its high effectiveness, safety and acceptability. Products containing gestoden include Meliane, which contains 20 ug of ethinylestradiol and 75 ug of gestodene; and Gynera, which contains 30 ug of ethinylestradiol and 75 ug of gestodene. Gestodene is androgenically neutral, meaning that contraceptive pills containing gestodene do not exhibit the androgenic side effects (e.g. acne, hirsutism, weight gain) often associated with second-generation contraceptive pills. Gestodene displays a high binding affinity to the progesterone receptor, also binds to adrogen and glucocorticoid receptors but no measurable affinity for the estrogen receptor.
