Doripenem is a synthetic carbapenem that has broad antibacterial potency against aerobic and anaerobic gram-positive and gram-negative bacteria. Doripenem is structurally related to beta-lactam antibiotics and shares the bactericidal mode of action of other β-lactam antibiotics by targeting penicillin-binding proteins (PBPs) to inhibit the biosynthesis of the bacterial cell wall. Doripenem is resistant to hydrolysis by most β-lactamases and is resistant to inactivation by renal dehydropeptidases. Doripenem has many similarities to the other carbapenems, as well as some important differences, such as greater potency against Pseudomonas aeruginosa. It was found to be similar to comparator agents. The most common adverse effects related to doripenem therapy were headache, nausea, diarrhea, rash, and phlebitis.

Rapacuronium bromide (RAPLON), a nondepolarizing neuromuscular blocking agent, is a negative allosteric modulator of muscarinic acetylcholine receptors. Rapacuronium bromide is indicated as an adjunct to general anesthesia to facilitate tracheal intubation and to provide skeletal muscle relaxation during surgical procedures. There were no specific pharmacokinetic studies conducted to examine the drug-drug interactions of RAPLON. Due to the risk of fatal bronchospasm, it was withdrawn from the United States market less than 2 years after its FDA approval.

Subitramine is a potent inhibitor of monoamines (serotonin, dopamine, noradrenaline) reuptake that was approved by FDA for the treatmen of obesity. Sibutramine is metabolized to metabolites M1 and M2 which are more active toward the monoamine transporters.The drug was withdrawn from the market because of clinical trial data indicating an increased risk of heart attack and stroke. It was sold under a variety of brand names including Reductil, Meridia and Sibutrex.

Eprosartan is an angiotensin II receptor antagonist used for the treatment of high blood pressure. It acts on the renin-angiotensin system in two ways to decrease total peripheral resistance. First, it blocks the binding of angiotensin II to AT1 receptors in vascular smooth muscle, causing vascular dilatation. Second, it inhibits sympathetic norepinephrine production, further reducing blood pressure. Eprosartan is indicated for the management of hypertension alone or in combination with other classes of antihypertensive agents. Also used as a first-line agent in the treatment of diabetic nephropathy, as well as a second-line agent in the treatment of congestive heart failure (only in those intolerant of ACE inhibitors).

Dolasetron is an antinauseant and antiemetic agent, which is approved as a mesylate salt under the brand name anzement for the prevention of nausea and vomiting associated with moderately emetogenic cancer chemotherapy, including initial and repeat courses; and for the prevention of postoperative nausea and vomiting. Dolasetron is a highly specific and selective serotonin 5-HT3 receptor antagonist. The serotonin 5-HT3 receptors are located on the nerve terminals of the vagus in the periphery and centrally in the chemoreceptor trigger zone of the area postrema. It is thought that chemotherapeutic agents produce nausea and vomiting by releasing serotonin from the enterochromaffin cells of the small intestine, and that the released serotonin then activates 5-HT3 receptors located on vagal efferents to initiate the vomiting reflex. This drug is not shown to have activity at other known serotonin receptors, and has low affinity for dopamine receptors. Dolasetron mesilate is rapidly reduced by carbonyl reductase to form its major pharmacologically active metabolite reduced dolasetron. In addition dolasetron was in the phase III clinical trials for the investigation, that intravenous using of dolasetron mesilate reduces pain intensity in patients with fibromyalgia.

Alatrofloxacin is a fluoroquinolone antibiotic developed as a mesylate salt and was sold under brand name Trovan, but was withdrawn from the U.S. market in 2001. Trovan was indicated for the treatment of patients initiating therapy in in-patient health care facilities (i.e., hospitals and long term nursing care facilities) with serious, life- or limb-threatening infections caused by susceptible strains of the designated microorganisms in the conditions listed below. Nosocomial pneumonia caused by Escherichia coli, Pseudomonas aeruginosa, Haemophilus influenzae, or Staphylococcus aureus. Community acquired pneumonia caused by Streptococcus pneumoniae, Haemophilus influenzae, Klebsiella pneumoniae, Staphylococcus aureus. Complicated intra-abdominal infections, including post-surgical infections caused by Escherichia coli. Gynecologic and pelvic infections including endomyometritis, parametritis, septic abortion and post-partum infections caused by Escherichia coli, Bacteroides fragilis, viridans group streptococci, Enterococcus faecalis. Complicated skin and skin structure infections, including diabetic foot infections, caused by Staphylococcus aureus, Streptococcus agalactiae, Pseudomonas aeruginosa, Enterococcus faecalis, Escherichia coli, or Proteus mirabilis. After intravenous administration, alatrofloxacin is rapidly converted to trovafloxacin, which is responsible for therapeutic effect. Plasma concentrations of alatrofloxacin are below quantifiable levels within 5 to 10 minutes of completion of a 1 hour infusion.
