Conditions:
Estramustine is an antineoplastic agent indicated in the palliative treatment of patients with metastatic and/or progressive carcinoma of the prostate. Estramustine is a combination of estradiol with nitrogen mustard. In vivo, the nitrogen-mustard moiety becomes active and participates in alkylation of DNA or other cellular components. This causes DNA damage in rapidly dividing cancerous cells leading to cell death and ideally, tumor shrinkage. Also, due to the drugs estrogen component, it can bind more selectively to active estrogen receptors. Used for the palliative treatment of patients with metastatic and/or progressive carcinoma of the prostate.

Conditions:
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.

Cefotaxime sodium is a semisynthetic, broad spectrum cephalosporin antibiotic for parenteral administration. It’s a 3rd Generation Cephalosporin that is FDA approved for the treatment of lower respiratory tract infections, genitourinary infections, gynecologic infections, bacteremia/septicemia, skin and skin structure infections, intra-abdominal infections, bone and/or joint infections and central nervous system infections. The bactericidal activity of cefotaxime sodium results from inhibition of cell wall synthesis. Cefotaxime sodium has in vitro activity against a wide range of gram-positive and gram-negative organisms. Cefotaxime sodium has a high degree of stability in the presence of ß-lactamases, both penicillinases and cephalosporinases, of gram-negative and gram-positive bacteria. Increased nephrotoxicity has been reported following concomitant administration of cephalosporins and aminoglycoside antibiotics. Common adverse reactions include injection site pain, injection site phlebitis, rash, diarrhea, vomiting. Increased nephrotoxicity has been reported following concomitant administration of cephalosporins and aminoglycoside antibiotics.

Conditions:
Dipivefrin is a prodrug with little or no pharmacologically activity until it is hydrolyzed into epinephrine inside the human eye. The liberated epinephrine, an adrenergic agonist, appears to exert its action by stimulating α -and/or β2-adrenergic receptors, leading to a decrease in aqueous production and an enhancement of outflow facility. The dipivefrin prodrug delivery system is a more efficient way of delivering the therapeutic effects of epinephrine, with fewer side effects than are associated with conventional epinephrine therapy. Dipivefrin is used as initial therapy for the control of intraocular pressure in chronic open-angle glaucoma.

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.

Sisomicin is a new broad-spectrum aminoglycoside most closely related structurally to gentamicin C1a. In vitro and in experimental infections, sisomicin has been found to be more potent than or nearly as potent as the most active of the other available aminoglycosides. Although susceptible to many (but not all) aminoglycoside-inactivating enzymes, sisomicin is active against many microorganisms that are resistant to other aminoglycosides by nonenzymatic mechanisms. Sisomicin has been shown to interact synergistically with various beta-lactam antibiotics against enterococci, staphylocicci, Enterobacteriaceae, and nonfermentative gram-negative bacilli. The pharmacokinetics and toxicity of sisomicin in humans appear to be similar to those of gentamicin, despite earlier reports of greater acute toxicity in animals. Sisomicin binds to 30s and 50s ribosomal subunits of susceptible bacteria disrupting protein synthesis, thus rendering the bacterial cell membrane defective.

Ritodrine (trade name Yutopar) is beta-2 adrenergic agonist used to stop premature labor. Ritodrine binds to beta-2 adrenergic receptors on the outer membrane of the myometrial cell, activates adenyl cyclase to increase the level of cAMP which decreases intracellular calcium and leads to a decrease of uterine contractions. In addition to stimulating the beta-2–adrenergic receptors of the uterine smooth muscle, ritodrine stimulates beta-adrenergic receptors of bronchial and vascular smooth muscles. The cardiostimulatory effects, including increased cardiac output, increased maternal and fetal heart rates, and widening of the maternal pulse pressure, are probably due to relaxation of the vascular smooth muscle. Relaxation of vascular smooth muscle stimulates the beta-1–adrenergic receptors and the reflex response to blood pressure. Also, during intravenous administration, ritodrine transiently increases maternal and fetal blood glucose and maternal plasma insulin concentrations. Other metabolic changes include increased cAMP, lactic acid, and free fatty acids, and decreased serum potassium concentration. Most side effects of β2 agonists result from their concurrent β1 activity and include the increase in heart rate, rise in systolic pressure, decrease in diastolic pressure, chest pain secondary to myocardial infarction, and arrhythmia. Beta-agonists may also cause fluid retention secondary to decrease in water clearance, which when added to the tachycardia and increased myocardial work, may result in heart failure. In addition, they increase gluconeogenesis in the liver and muscle resulting in hyperglycemia, which increases insulin requirements in diabetic patients. The passage of β agonists through the placenta does occur and may be responsible for fetal tachycardia, as well as hypoglycemia or hyperglycemia at birth.

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.
