Butriptyline is a tricyclic antidepressant used in patients with depression associated with anxiety. The drug is supposed to be withdrawn from the market as the last publication about its clinical use is dated by 1988.

Cinepazet is an ethyl ester of cinepazic acid. It acts by inhibiting the influx of extracellular calcium into cells through the slow calcium channel in the cell membrane. In the 1970s cinepazet was marketed in France and Italy under tradename Vascoril for the treatment of angina.

Carbuterol is a beta-adrenergic bronchodilator with selectivity for bronchial smooth muscle relative to cardiac and vascular tissues of several species including man. In vitro studies demonstrated that carbuterol was a direct acting beta-adrenergic agonist, not dependent on endogenous catecholamine release, and was devoid of alpha-adrenergic agonist activity. The activity of the racemate was shown to reside primarily in the l-enantiomer. Carbuterol inhibited immunologically induced release of histamine and slow reacting substance of anaphylaxis from passively sensitized fragmented rhesus monkey lung and also inhibited passive cutaneous anaphylaxis in rats. Acute toxicity studies in mice, rats and guinea pigs indicated a wide safety margin for carbuterol. Carbuterol is a safer and more effective bronchodilator than ephedrine.

Chloroprednisone is a glucocorticoid. The acetated ester prodrug was used as topical anti-inflammatory agent.

Cefpirome is a semisynthetic, broad-spectrum, fourth-generation cephalosporin with antibacterial activity. Cefpirome binds to and inactivates penicillin-binding proteins (PBPs) located on the inner membrane of the bacterial cell wall. PBPs are enzymes involved in the terminal stages of assembling the bacterial cell wall and in reshaping the cell wall during growth and division. Inactivation of PBPs interferes with the cross-linkage of peptidoglycan chains necessary for bacterial cell wall strength and rigidity. This results in the weakening of the bacterial cell wall and causes cell lysis. Cefpirome is an injectable extended-spectrum or 'fourth generation' cephalosporin. Its antibacterial activity encompasses many of the pathogens involved in hospital-acquired infections such as Enterobacteriaceae, methicillin-susceptible Staphylococcus aureus, coagulase-negative staphylococci and viridans group streptococci. Cefpirome also has in vitro activity against Streptococcus pneumoniae regardless of penicillin susceptibility. It is stable against most plasmid- and chromosome-mediated beta-lactamases, with the exception of the extended-spectrum plasmid-mediated SHV enzymes. Intravenous cefpirome 2g twice daily has shown clinical efficacy comparable to that of ceftazidime 2g 3 times daily in the treatment of hospitalised patients with moderate to severe infections. Clinical response and bacteriological eradication rates were similar in patients with severe pneumonia or septicaemia treated with either cefpirome or ceftazidime. Cefpirome appeared more effective than ceftazidime in the eradication of bacteria in patients with febrile neutropenia in 1 study; however, clinical response rates were similar in the 2 treatment groups. The tolerability of cefpirome appears similar to that of ceftazidime and other third generation cephalosporins, diarrhoea being the most frequently observed event. Thus, cefpirome is likely to be a valuable extended-spectrum agent for the treatment of severe infections. Cefpirome offers improved coverage against some Gram-positive pathogens and Enterobacteriaceae producing class I beta-lactamases compared with the third generation cephalosporins, although this has yet to be demonstrated in clinical trials.

Difetarsone, an anthelmintic drug, was used in the treatment of Trichuris trichiura (whipworm) infestation.

Isobromidione is an indanedione. It was used as a uricosuric agent.

Tertatolol is a beta-blocker with unique renal vasodilatatory effects, mainly at the level of the microcirculation. The mechanisms of this renal vasodilatation are not fully understood but might involve renal 5-HT1A receptor stimulation. It is a potent competitive antagonist of 5-HT1A and 5-HT1B receptors. Tertatolol inhibits human mesangial cell proliferation. Biochemical surveillance did not show any adverse metabolic effects of tertatolol. Tertatolol is rapidly and totally absorbed by the gastro-intestinal tract with a low presystemic metabolism, and the bioavailability is not affected by food intake. It is used as antihypertension agent.

Levosulpiride [RV 12309, L-sulpiride, levosulpride, Dislep® 25, Levopride®, Levopraid®] is a potent dopamine D2 receptor blocker that was originated by Ravizza Farmaceutici (now AbbVie). Levosulpiride is the levo enantiomer of sulpiride. The levo enantiomer shows better/similar pharmacological actions and lower incidence of toxic effects than both dextro as well as the racemic forms of the drug. Levosulpiride is marketed in Italy and South Korea, and is possibly available elsewhere in Europe and Asia. Levosulpiride does not appear to be available in North America. Levosulpiride is available as 25mg tablets, drops and in ampoules for parenteral administration. Generic versions of levosulpiride also appear to be available in some countries. Levosulpiride is primarily indicated in conditions like Anxiety, Depression, Gastro-esophageal reflux disease, Irritable bowel syndrome, Schizophrenia, Tourette's syndrome, dyspeptic syndrome, essential cephalgia, and can also be given in adjunctive therapy as an alternative drug of choice in Peptic ulcer, Vertigo.

Cinepazide or cinepazide maleate (Kelinao or Anjieli in China) is a vasodilator used in China for the treatment of cardiovascular and cerebrovascular diseases, and peripheral vascular diseases. As a calcium channel blocker, cinepazide can stop calcium from entering vascular smooth muscle cells and relax smooth muscles of cerebral vessels, coronary arteries and peripheral vessels so as to relieve vasospasm, reduce vascular resistance, improve flexibility of red blood cells, increase blood circulation in cerebral vessels and improve microcirculation and brain metabolism. Cinepazide could also increase the number of cAMP by inhibiting cAMP phosphodiesterase and reduce oxygen consumption. In April 2002, cinepazide of Beijing Hwellso Pharmaceutical Co., Ltd was approved to enter the market with two dosage forms of oral formulation and injection under the trade name of Kelinao. Currently, Kelinao is the only domestic brand for the treatment of cardiovascular diseases. And in 2009, cinepazide was included in the national medicare drug list. Cinepazide maleate, after wide application, has gained the recognition of Chinese doctors and patients for the treatment of cerebral arteriosclerosis, transient ischemic attack, cerebral thrombosis, cerebral embolism, cerebral hemorrhage sequel and post-traumatic brain syndrome. Besides, due to its efficacy in cardiovascular diseases and peripheral vascular diseases, cinepazide maleate has become a leading product in cerebrovascular drug market.
