Higenamine HCl (norcoclaurine) is a plant-based alkaloid widely used as nutritional supplement in food and beverage industries. It exists in variety of plants including Tinospora crispa, Nandina domestica, Gnetum Parvifolium C.Y. Cheng, sarum Heterotropoides, Nelumbo nucifera. It was initially isolated from Aconitum and identified as the active cardiotonic component of this medicinal plant used as local and traditional medicines in many Asian regions for the treatment of various diseases such as collapse, syncope, painful joints, oedema, bronchial asthma etc. Various pharmacological properties and potentially multi-spectral medical applications of higenamine have been reviled in many in vitro and in vivo studies conducted in animals and humans. Pharmacological properties of higenamine include positive inotropic and chronotropic effect, activating slow channel effect, vascular and tracheal relaxation effect, anti-thrombotic, anti-apoptotic and anti-oxidative effect, anti-inflammatory and immunomodulatory effect. Studies on higenamine showed potential therapeutic effects for diseases like heart failure, disseminated intravascular coagulation (DIC), shock, arthritis, asthma, ischemia/reperfusion injuries and erectile dysfunction. Higenamine has been tested as a candidate of pharmacologic stress agent in the detection of coronary artery diseases (CADs) in human clinical studies in China. In animal models, higenamine has been demonstrated to be a β2 adrenoreceptor agonist. It partly exerts its actions by the activation of adenylate cyclase, responsible for boosting the cellular concentrations of the adrenergic second messenger, cAMP. Via a beta-adrenoceptor mechanism higenamine, induced relaxation in rat corpus cavernosum, leading to improved vasodilation and erectile function. Related to improved vasodilatory signals, higenamine has been shown to possess antiplatelet and antithrombotic activity via a cAMP-dependent pathway, suggesting it may contribute to enhanced vasodilation and arterial integrity. Anti-apoptotic and cardiac protective effects of higenamine were shown to be mediated by the β2-AR/PI3K/AKT cascade. Higenamine is marketed as a dietary supplement for weight loss and sport performance, and is added to many fat burning supplements. Along with many other β2 agonists, higenamine is prohibited by World Anti-Doping Agency for use in sports.

Cilnidipine (FRC-8653) is a dihydropyridine (DHP) type of calcium channel antagonist. The L-type Ca2+ channel blockade by cilnidipine affects predominantly vascular smooth muscle, thereby producing vasodilation of peripheral resistance vessels and coronary arteries. The blockade of N-type Ca2+ channels affects predominantly peripheral nerve endings of sympathetic neurons, thereby dilating blood vessels by lowering plasma catecholamine levels. Furthermore, renoprotective and neuroprotective effects as well as cardioprotective action of cilnidipine have been demonstrated in clinical practice or animal examinations. Cilnidipine was originated by Fuji & Rebio Pharmaceutical Co., Ltd. and developed jointly with Ajinomoto for the treatment of hypertension. Cilnidipine has been launched in Japan.

Proxibarbal is a non-sedative barbiturate with a specific anti-serotonin and anti-histamine effect, due to enzyme induction of serotoninase and histaminase. Its lack of unpleasant side-effects. Proxibarbal exists in ring-chain tautomeric equilibrium with the two diastereomers of valofan. Proxibarbal is metabolized to a five-membered lactone. Its only barbituric property is its ability to induce enzymes that destroy a surplus of neurohormones and rid people of their neurovegetative sufferings, including migraine and other types of vascular headache. Side effects are: dizziness, drowsiness, dyspepsia, allergic reactions. Proxibarbal enhances the effects of other depriving agents, including alcohol.
Magnesium glutamate hydrobromide (Psychoverlan) is a known sedative and muscle relaxant. In a long-term study 19 young females were treated with Psychoverlan capsules or syrup for an average of 11.4 months. Intolerance phenomena and side-effects were not seen. It was even decided to increase the standard dose. None of the patients developed brominism or bromine intoxication. The general state of health of 13 of the 19 subjects was improved by the harmonizing effect of the drug on psychic and vegetative functions. Tiredness and somnolence were not observed.

Meldonium (3-(2,2,2-trimethylhydrazinium)propionate; MET-88; quaterine, trade-named as Mildronate) is an antiischemic drug developed at the Latvian Institute of Organic Synthesis. It is a clinically used in the treatment of heart failure, myocardial infarction, arrhythmia, atherosclerosis, and diabetes. Mechanism of action is based on the regulation of energy metabolism pathways through l-carnitine lowering effect. L-Carnitine biosynthesis enzyme γ-butyrobetaine hydroxylase and carnitine/organic cation transporter type 2 (OCTN2) are the main known drug targets of meldonium, and through inhibition of these activities, meldonium induces adaptive changes in the cellular energy homeostasis. Since L-carnitine is involved in the metabolism of fatty acids, the decline in its levels stimulates glucose metabolism and decreases concentrations of l-carnitine related metabolites, such as long-chain acylcarnitines and trimethylamine-N-oxide. Meldonium is used in neurological clinics for the treatment of brain circulation disorders. It appears to improve patients' mood; they become more active, their motor dysfunction decreases, and asthenia, dizziness, and nausea become less pronounced. CNS effects of Meldonium could be mediated by stimulation of the nitric oxide production in the vascular endothelium by modification of the gamma-butyrobetaine and its esters pools. It is hypothesized that mildronate may increase the formation of the gamma-butyrobetaine esters. Meldonium was on the World Anti-Doping Agency’s (WADA) list of drugs being monitored until September 2015, when it was added to the list of banned substances, effective January 1, 2016.
Pholcodine is an opioid that has been widely used worldwide since 1950 for the treatment of non-productive cough in children and adults. Illicit drug. Additionally Pholcodine is a marker for sensitization to neuromuscular blocking agents (NMBA) and is intended for use as a diagnostic tool in NMBA-induced anaphylaxis.

Bradykinin, a pro-inflammatory mediator is also a neuromediator and regulator of several vascular and renal functions. Bradykinin can act as a vasoactive substance along with histamine in inflammation and swelling as it is a potent vasodilator. In addition, it triggers the release of other mediators such as nitric oxide in inflammatory and cancer tissues. Bradykinin acts via specific cell surface receptors: bradykinin receptor, B1 and B2 that are G-protein coupled receptors of the seven-transmembrane domain family. It was shown that increased plasma levels of bradykinin lead to the angioedema as the common major clinical manifestation. Bradykinin was also studied in heart transplant recipients and in obesity patients, but these studies were terminated or withdrawn for different reasons. Bradykinin is also an important growth factor for many cancers. Bradykinin antagonists showed higher potency than standard anti-cancer drugs, without evident toxicity to the hosts, that is why they have great promise for the development of new anti-cancer drugs.

Indoprofen is one of several NSAIDs that have been withdrawn from the market due to causing severe gastrointestinal bleeding. The UK Licensing Authority suspended the product license on grounds of safety in 1983 and in 1984 the Italian manufacturers decided to withdraw it from the world market. The UK decision was taken because there was a high rate of adverse drug reactions in a voluntary postmarketing surveillance study and the spontaneous adverse reaction reporting system had noted 217 serious adverse effects, mainly gastrointestinal bleeding and perforation.

Acetylleucine is a drug that is used for symptomatic treatment of acute vestibular vertigo and dizziness. Its pharmacodynamics are not fully understood. The hypothesis is that it restores the membrane potential, via an interaction with membrane phospholipids on the injured side of vestibular neurons mainly in the thalamus or parietal region of the cortex. Clinical trials on animals showed an improvement in locomotor balance after forced rotation or unilateral vestibular neurotomy. Acetylleucine has a marketing authorisation in France although there is no evidence of its efficacy on human. Acetylleucine neither reduced the nausea associated with this provocative stimulus, nor hastened the acquisition or retention of vestibular habituation of motion sickness and nystagmus.
