Niflumic acid belongs to the group of nonsteroidal anti-inflammatory drugs (NSAIDs) and used in the treatment of rheumatoid arthritis, and joint and muscular pain. Its mechanism of action is believed to be based on selective inhibition of cycloxygenases-2 that results in antipyretic, analgesic, and anti-inflammatory effects. In addition to these effects on prostaglandin synthesis, it has been shown to act as a positive allosteric modulator on α1β2γ2 and as a negative modulator on α6β2 and α6β2γ2 (and α1β2) GABAA receptors. In addition, was reported, that niflumic acid blocked T-type calcium channels. It is available for clinical use in several European countries.

Isoconazole is structurally related to miconazole and econazole and was synthesized by Janssen Pharmaceutica. The compound has been marketed in several countries, but not in the United States. It has broad-spectrum activity in vitro against dermatophytes, pathogenic yeasts, pathogenic filamentous fungi, gram-positive bacteria, and trichomonads . The mode of action appears to include rapid reduction in ATP concentrations caused by damage to the fungal cell membrane. Isoconazole interacted with the cell wall and caused convolutions and wrinkles. Isoconazole also inhibited the enzyme-catalyzed release of spheroplasts from young yeast cells. A recent study has demonstrated that application of the free base of isoconazole in combination with a volatile/nonvolatile vehicle, e.g., ethanol/propylene glycol, can increase drug bioavailability in the skin. This observation may lead to newer formulations of isoconazole and broaden its use for topical (e.g., spray) treatment of yeast and dermatophytic infections. Dermatophytic Isoconazole has been developed and marketed primarily as a once-a-day, topical anti-Candida agent for the treatment of vaginal candidiasis. Studies evaluating isoconazole have demonstrated that 80 to 90% of patients with vaginal candidiasis who were treated once a day with the drug remained clinically and mycologically cured. Following insertion of two 300-mg tablets, concentrations of isoconazole in the vagina remained above minimum inhibitory and minimum fungicidal levels for at least 72 h. Isoconazole has been developed and marketed primarily as a once-a-day, topical anti-Candida agent for the treatment of vaginal candidiasis. In clinical studies, very little of the drug entered the blood after a single vaginal application of a 600-mg dose; the same dose did not adversely affect intestinal flora by inducing a proliferation of yeast like species following prolonged administration. Studies evaluating demonstrated that 80 90% of patients.

Bumecaine (Pyromecaine) is a local anesthetic and anti-arrhythmic drug. It is indicated as an agent for superficial anesthesia during medical and diagnostic procedures in dentistry, ophthalmology, otorhinolaryngology, surgery, bronchology, gastroenterology, urology. The experiments on the isolated neurons in the rat spinal ganglions have shown that interaction of pyromecaine with inactivated Na+ channels makes a considerable contribution to the blocking effect of anesthesia. Oral administration of pyromecaine pills considerably depresses platelet aggregation and even causes platelet disaggregation. Possible side effects are: general weakness, nausea, vomiting, headache, dizziness, fainting, a drop in blood pressure. Quinidine increases the risk of side effects.

Ribostamycin sulfate is an aminoglycoside-aminocyclitol antibiotic isolated from a streptomycete. It is an important broad-spectrum antibiotic with important use against human immunodeficiency virus and is considered a critically important antimicrobial by the World Health Organization. Aminoglycosides work by binding to the bacterial 30S ribosomal subunit (some work by binding to the 50S subunit), inhibiting the translocation of the peptidyl-tRNA from the A-site to the P-site and also causing misreading of mRNA, leaving the bacterium unable to synthesize proteins vital to its growth. Ribostamycin is usually used to treat sepsis, superficial skin infection, deep skin infection, lymphangitis/lymphadenitis, chronic pyoderma, osteomyelitis, pharyngitis/laryngitis, tonsillitis, acute bronchitis, pneumonia, pulmonary abscess, pyothorax, secondary infection in chronic respiratory lesions, cystitis, pyelonephritis, gonococcal infection, peritonitis, cholecystitis, dacryocystitis, keratitis (including corneal ulcer), otitis media, sinusitis and gnathitis. The most commonly reported adverse reactions include renal dysfunction, liver disorder and rash.

Neo-Gilurythmal (or prajmaline), an antiarrhythmic agent, which is used to treat angina pectoris, Wolff–Parkinson–White Syndrome and coronary artery disease. Neo-Gilurythmal found to be effective even in the case where other previously used antiarrhythmics were ineffective.

Flunarizine is a selective calcium entry blocker with calmodulin binding properties and histamine H1 / dopamine D2 blocking activity. It is not available in the US but marketed in other countries for prophylaxis of a migraine, occlusive peripheral vascular disease, the vertigo of central and peripheral origin, motion sickness and as an adjuvant in the therapy of epilepsy. The drug is also investigated for the treatment of schizophrenia.

Azelnidipine (INN; marketed under the brand name CalBlock) is a dihydropyridine calcium channel blocker. It is sold in Japan by Daiichi-Sankyo pharmaceuticals, Inc. Azelnidipine is a new dihydropyridine calcium channel antagonist with selectivity for both L-type and T-type Ca channels. It has recently been approved in Japan for the treatment of patients with hypertension. Results from clinical trials showed that long-term treatment with azelnidipine effectively controls blood pressure (BP) in a cohort of 95 patients with mild-to-moderate hypertension. The antihypertensive efficacy of azelnidipine in patients with mild-to-moderate hypertension was shown to be similar to that of amlodipine or nitrendipine in a randomised double-blind study. Azelnidipine and amlodipine controlled 24-hour BP to a similar extent. Azelnidipine is generally well tolerated. Vasodilator adverse events such as headache and hot facial flushes account for most of the adverse events. Its use is not associated with reflex tachycardia.

Pirmenol is an antiarrhythmic agent, which exhibits effects on the fast action potential similar to other class 1 membrane active antiarrhythmic agents. Pirmenol depresses not only the fast Na+ channel, but also others, such as the slow Ca2+ and K+ channels. Pirmenol had sevenfold lower affinity for glandular-type muscarinic receptors (M3) than for cardiac-type muscarinic receptors (M2). This medicine regulates disturbed pulse by acting on the cardiac muscle. Usually, used for treatment of tachyarrhythmia (ventricular). The most commonly reported adverse reactions include constipation, discomfort in stomach, difficulty in urination (urinary retention), headache, insomnia, bitterness in the mouth, nausea, dry mouth and palpitation. Lidocaine, procainamide and quinidine a greater degree of arrhythmia conversion occurred when dosed 15 min after pirmenol than when these agents were dosed alone.

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.

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.
