Propyromazine bromide is a quatemary ammonium with muscarinic cholinoceptor antagonistic activity. This antimuscarinic agent with peripheral effects similar to those of atropine is given in the symptomatic treatment of visceral spasm.
Thiobutabarbital is a barbiturate derivative invented in the 1950s. It has sedative, anticonvulsant and hypnotic effects, it is used in veterinary medicine for induction in surgical anaesthesia. Thiobutabarbital was formerly used as anesthetic Inactin. ‘Inactin’ (sodium thiobutabarbital) produces smooth induction of anaesthesia after intravenous administration and has a prolonged duration of action. It has variable analgesic activity.

Casopitant (GW679769) is a novel substituted piperidine derivative that competitively binds with NK1 receptors. The full occupancy of the receptor by their piperidine compound inhibits its binding with tachykinin neurotransmitters, including SP. Casopitant, in a series of in vitro and in vivo experimentations, has exhibited a potent NK1 receptor antagonism. On 29 May 2008, GlaxoSmithKline announced the submission of a new drug application to the FDA for intravenous and oral formulations of casopitant mesylate. This drug was proposed for the prevention of chemotherapy-induced nausea and vomiting as an add-on therapy to the standard dual therapy of 5-HT3 receptor antagonists + dexamethasone. The submission also included a proposed indication for postoperative nausea and vomiting prevention. Rezonic™ is the proposed trade name for casopitant mesylate in the United States; Zunrisa™ is the proposed trade name for casopitant mesylate for GlaxoSmithKline’s global group of companies. In September 2009, GlaxoSmithKline decided to discontinue all regulatory filings for casopitant based on an estimate of the amount of additional safety data.

Pefloxacin is a fluorinated quinolone that is structurally related to nalidixic acid. It can be administered both orally and intravenously, and has a broad spectrum of in vitro activity against Gram-negative organisms and staphylococci. The bactericidal action of pefloxacin results from interference with the activity of the bacterial enzymes DNA gyrase and topoisomerase IV, which are needed for the transcription and replication of bacterial DNA. DNA gyrase appears to be the primary quinolone target for gram-negative bacteria. Topoisomerase IV appears to be the preferential target in gram-positive organisms. Interference with these two topoisomerases results in strand breakage of the bacterial chromosome, supercoiling, and resealing. As a result DNA replication and transcription is inhibited. It is prescribed for the treatment of uncomplicated gonococcal urethritis in males and for gram-negative bacterial infections in gastrointestinal system and genitourinary tract.

Flupirtine is a triaminopyridine derivative having a chemical structure - 2-amino-3-ethoxy-carbonylamino-6-4-fluoro-benzylamino-pyridine. The basic molecule used for synthesis of flupirtine was 2, 6-dichoro 3-nitropyridine. It was first synthesized in 1980s in Germany and was marketed by Degussa Pharma. Flupirtine is a centrally acting, non-opioid analgesic that is available in a number of European countries for the treatment of a variety of pain states. The therapeutic benefits seen with flupirtine relate to its unique pharmacological properties. Flupirtine displays indirect NDMA receptor antagonism via activation of potassium channels and is the first representative of a pharmacological class denoted the 'selective neuronal potassium channel openers'. The generation of the M-current is facilitated by flupirtine via the opening of neuronal Kv7 potassium channels. The opening of these channels inhibits exaggerated neuronal action potential generation and controls neuronal excitability. Neuronal hyperexcitability is a physiological component of many pain states such as chronic pain, migraine and neurogenic pain.

Iophendylate (Pantopaque (in USA) or Myodil, formerly manufactures by Glaxo Laboratories (London,UK) was commonly used from the 1940s until the late 1980s for myelography, cisternography, and ventriculography; the use of oil-based contrast agents such as Myodil has been discontinued, and images of intradural oil-based contrast are rarely encountered at present. In 1942 Van Wagenen (a neurosurgical colleague of Warrens, at the University of Rochester) identified Iophendylate as causing chemical meningitis in 30 patients where "space-displacing masses within the spinal canal were suspected". Iophendylate has been shown to be both a radiographic and magnetic resonance (MR) contrast agent in patients with suspected cord abnormalities who underwent MR examination following myelography. The iophendylate appears as a linear band of high signal intensity along the dependent portion of the spinal canal on MR images obtained with a repetition time of 500 msec and an echo time of 30 msec. Recently was published report, where depicted a unique case of posteriorly located subdural trapped Myodil, about three decades after myelography. The clinical picture of that case highlighted that such a complication didn’t carry the risk of arachnoiditis and could remain silent for several decades. Although Iophendylate is not used for evaluation of spinal disease anymore in the modern diagnostic era, its former use and its intrathecal persistence makes its recognition in MR imaging important. That case emphasized the necessity of awareness about these rare features which continue to present even decades after abandonment of oil-based myelography.

Delapril is a lipophilic nonsulfhydryl angiotensin-converting enzyme (ACE) inhibitor, which has been shown to exert potent ACE inhibitory activity and is marketed as an antihypertensive drug. Delapril has been shown to exist in solution as a mixture of s-cis and s-trans conformational isomers, as a result of restricted rotation about the amide bond.

Indobufen inhibits platelet aggregation by reversibly inhibiting the platelet cyclooxygenase enzyme thereby suppressing thromboxane synthesis. Indobufen under brand name ibustrin is used in Italy for the following conditions: cerebrovascular insufficiency, atherosclerosis of peripheral and cerebral vessels, thrombophlebitis, deep vein thrombosis, and diabetes mellitus. In addition, this drug has been investigated in the phase II clinical trial for the prevention of thromboembolic events in patients with nonrheumatic atrial fibrillation. After oral administration, it is quickly and completely absorbed.
