Bacampicillin is a penicillin antibiotic. It is a prodrug of ampicillin with improved oral bioavailability. It exerts bactericidal activity via inhibition of bacterial cell wall synthesis by binding one or more of the penicillin binding proteins (PBPs). Spectrobid is used to treat bacterial infections such as tonsillitis, pneumonia (lung infection), bronchitis (inflammation of airway), urinary tract infections, gonorrhea, and infections of the skin. Adverse effects are: anemia, thrombocytopenia, neutropenia, agranulocytosis, seizures, nephrotoxicity, Jarisch-Herxheimer Reaction (fever, chills, sweating, tachycardia, hyperventilation, flushing, and myalgia). Drug interactions: Contraceptives - decreased contraceptive effectiveness; Live Typhoid Vaccine - decreased immunological response to the typhoid vaccine; Probenecid - increased bacampicillin levels.

Conditions:

Meclocycline is a tetracycline antibiotic. It is used topically for skin infections treatment. Tetracyclines are broad-spectrum bacteriostatic agents and act by inhibiting protein synthesis by blocking the binding of aminoacyl tRNA (transfer RNA) to the mRNA (messenger RNA) ribosome complex. Meclocycline might increase sensitivity to light when it is used with Aminolevulinic acid.

Ticrynafen, or tienilic acid, is a diuretic drug with uric acid-lowering action, formerly marketed for the treatment of hypertension. It was withdrawn from the market only months after its introduction because of reports of serious incidents of drug-induced liver injury including some fatalities. Its hepatotoxicity is considered to be primarily immunoallergic in nature. Tienilic acid is a thiophene-containing mechanism-based inactivator of P450 2C9, resulting from covalent modification of the P450 2C9 protein. The bioactivation mechanism involves oxidation of the thiophene ring system.

Iodamide is an ionic monomeric iodinated radiographic contrast medium. It was used in many procedures and may be given intravenously or by other routes, for example by instillation into the bladder or uterus; it has also been used for computed tomography. It is usually given as a 24 to 65% solution of the meglumine salt, or as a mixture of the sodium and meglumine salts; solutions of the sodium salt have also been used. Iodamide is no longer marketed in the US.
Cefamandole (also known as cephamandole) is a broad-spectrum cephalosporin antibiotic. The clinically used form of cefamandole is an ester form, cefamandole nafate, a prodrug. Cefamandole is no longer available in USA, but it has prescription in UK. Cefamandole under brand name mandol is indicated for the treatment of serious infections caused by susceptible strains of the designated microorganisms such as: lower respiratory infections, including pneumonia, caused by S. pneumoniae. So as urinary tract infections caused by E. coli, Proteus spp.; peritonitis caused by E. coli and Enterobacter spp. Septicemia caused by E. coli; skin and skin structure infections caused by S. aureus; bone and joint infections caused by S. aureus (penicillinase- and non-penicillinase-producing). Like all beta-lactam antibiotics, cefamandole binds to specific penicillin-binding proteins (PBPs) located inside the bacterial cell wall, causing the 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 cefamandole interferes with an autolysin inhibitor.

Bretylium (bretylium tosylate) is an antifibrillatory and antiarrhythmic agent. Bretylium is abromobenzyl quaternary ammonium compound which selectively accumulates in sympathetic ganglia and their postganglionic adrenergic neurons where it inhibits norepinephrine release by depressing adrenergic nerve terminal excitability. The drug has a direct positive inotropic effect on the myocardium and blocking effect on postganglionic sympathetic nerve transmission. The drug is poorly absorbed orally, requiring either i.m. or i.v. administration.

Etidronate is a salt of etidronic acid (brand name Didronel, also known as EHDP) a diphosphonate, which is indicated for the treatment of symptomatic Paget’s disease of bone and in the prevention and treatment of heterotopic ossification following total hip replacement or due to spinal cord injury. Didronel is not approved for the treatment of osteoporosis. This drugs acts primarily on bone. It can inhibit the formation, growth, and dissolution of hydroxyapatite crystals and their amorphous precursors by chemisorption to calcium phosphate surfaces. Inhibition of crystal resorption occurs at lower doses than are required to inhibit crystal growth. Both effects increase as the dose increases. Preclinical studies indicate etidronate disodium does not cross the blood-brain barrier. Didronel is not metabolized. The amount of drug absorbed after an oral dose is approximately 3 percent. Bisphosphonates, when attached to bone tissue, are absorbed by osteoclasts, the bone cells that breaks down bone tissue. Although the mechanism of action of non-nitrogenous bisphosphonates has not been fully elucidated, available data suggest that they bind strongly to hydroxyapatite crystals in the bone matrix, preferentially at the sites of increased bone turnover and inhibit the formation and dissolution of the crystals. Other actions may include direct inhibition of mature osteoclast function, promotion of osteoclast apoptosis, and interference with osteoblast-mediated osteoclast activation. Etidronic acid may promote osteoclast apoptosis by competing with adenosine triphosphate (ATP) in the cellular energy metabolism. The osteoclast initiates apoptosis and dies, leading to an overall decrease in the breakdown of bone.
