Levormeloxifene (INN) is an experimental selective estrogen receptor modulator (SERM) that was being developed as an alternative to estrogen replacement therapy for the treatment and prevention of postmenopausal bone loss. Levormeloxifene is the levorotatory enantiomer of non-hormonal, non-steroidal oral contraceptive -- ormeloxifene (trade names Novex-DS, Centron, and Sevista). The development of Levormeloxifene was stopped because of a high incidence of gynecologic adverse events during clinical trials.

TILIDINE is a low to medium potency opioid analgesic. It is metabolized to its active metabolites, nortilidine and bisnortilidine. Its analgesic activity is largely exerted through nortilidine which is a potent agonist at Mu opioid receptors.

Proglumetacin (usually as the maleate salt, trade names Afloxan, Protaxon and Proxil) is a non-steroidal anti-inflammatory drug. Proglumetacin is indicated for the pain and inflammation associated with musculoskeletal and joint disorders. The action of proglumetacin maleate is qualitatively the same as that of indomethacin in vivo; that is, it inhibits cyclo-oxygenase in inflammatory sites.

Etamiphylline is the respiratory stimulant. No information is available about pharmacodynamics of etamiphylline. No human pharmacokinetic data are available. Etamiphylline seems to be a rather weaker bronchodilator than theophylline when administered orally.

Todralazine is a hydralazinophthalazine-derived drug currently used in the treatment of arterial hypertension. As vasodilator, it might be used in combination with isosorbide dinitrate. Side effects and drug toxicity were uncommon in such vasodilator therapy.

Benproperine (Cofrel) is a cough suppressant. It is used for symptomatic relief of cough. Cofrel is 2-4 times as potent as codeine in suppressing cough in animals. It acts peripherally by blocking afferent sensory nerve impulses originating from receptors in the lungs and pleura.

Dicethiamine hydrochloride (DCET) is a vitamin B(1) derivative that has excellent absorbability and transformability in tissues. It is an analogue of thiamine, improved performance in an animal model of complex fatigue.

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.

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.

Meclofenoxate (INN, BAN) (brand name Lucidril), also known as centrophenoxine, is a cholinergic nootropic used as a dietary supplement and drug in the treatment of symptoms of senile dementia and Alzheimer's disease. Meclofenoxate has been shown in studies to be effective in enhancing the memory and in improving the cognitive functions of the elderly. Some studies even suggest that Meclofenoxate has the ability to reverse the signs of brain aging. While claims about its ability as a nootropic agent have not been fully established in clinical trials, some studies do strongly suggest that it is indeed very effective in improving memory retention and recall. Meclofenoxate HCL Powder for Injection is also indicated for the following conditions: comma; skull and brain trauma; following a stroke; encephalopathy; mental disorders (in combination with psychotropic agents); mental and psychomotor retardation in children; brain intoxication; alcohol psychoses; neuritis and polyneuritis. The main mechanism of action of Meclofenoxate is generally believed to be cholinergic in nature. As an efficient transporter of DMAE, Meclofenoxate encourages the production of choline in the brain, which is then synthesized into acetylcholine. The more acetylcholine neurotransmitters in the brain, the better and more efficient the cognitive functions will be. Meclofenoxate also increases cellular membrane phospholipids
