Cafedrine, also known as norephedrinoethyltheophylline, is a chemical linkage of norephedrine and theophylline and is a cardiac stimulant used to increase blood pressure in people with hypotension. There are few data available for cafedrine. Cafedrine has a half-life of 60 min following both oral and intravenous administration Cafedrine is metabolized to norephedrine and several minor metabolites, but nearly 90% of the administered norephedrine is excreted via the kidneys, mostly unchanged, within 24 h. The effects of cafedrine on cardiac output are believed to be mediated via β- adrenoceptors. Cafedrine has a positive inotropic effect in humans, and this can be abolished by administration of the non-selective β-adrenoceptor antagonist propranolol. A combination of cafedrine and theodrenaline called Akrinor® is used for the treatment of hypotension in adults that occurs during emergency situations, general anesthesia, and regional anesthesia, especially during cesarean sections. Cafedrine/theodrenaline may have advantages over other vasopressor drugs. For example, it can be administered via bolus while catecholamines normally need to be diluted and administered via syringe pumps. Bolus injection is faster, which may be beneficial in emergency situations, plus it is more cost efficient with respect to the disposables. Cafedrine/theodrenaline has been widely used in Germany since 1963

Fendiline or Sensit (N-(3,3-diphenylpropyl)-(1-phenylethyl)-amine), is a diphenylalkylamine blocker of L-type calcium channels. Fendiline is an anti-anginal agent for the treatment of coronary heart disease. Pharmaco-dynamically, it exerts the typical calcium as well as calmodulin antagonistic actions: inhibition of the transmembrane calcium current, smooth muscle relaxation, negative inotropism, cardioprotection, inhibition of calmodulin-activated myosin light-chain kinase and phosphodiesterase. Pharmacokinetics reveal slow onset of action and a long half-life. The anti-anginal and anti-ischaemic efficacy of fendiline has been proven in several placebo-controlled, double-blind trials. Fendiline is an FDA-approved, albeit now clinically obsolete. Additionally, fendiline is a specific inhibitor of K-Ras plasma membrane localization that also inhibits K-Ras signal output and blocks the proliferation of K-Ras-transformed tumor cells.

Fenbutrazate is a prodrug of phenmetrazine, a psychostimulant for the treatment of obesity. Fenbutrazate acts as an agonist of monoamine transportes upon conversion to the active metabolite. The drug is no longer marketed due to its addictive profile.

Mifamurtide (liposomal muramyl tripeptide phosphatidylethanolamine; trade name Mepact) is an immunomodulator with antitumor effects that appear to be mediated via activation of monocytes and macrophages. After intravenous administration, mifamurtide is selectively phagocytosed by monocytes and macrophages. Cytosolic Mifamurtide specifically interacts with nucleotide-binding oligomerization domain 2 (NOD2) receptor that induces nuclear factor (NF)-kB activation and is implicated in innate immune defense. Activation of monocyte-mediated tumoricidal function was observed following in vivo treatment with mifamurtide in phase I/II clinical trials. Intravenous administration of mifamurtide inhibited tumor growth and increased survival in rodent models of lung and liver metastasis. In a large, randomized, open-label, multicenter, phase III trial, the addition of adjuvant (postoperative) mifamurtide to three- or four-drug combination chemotherapy (doxorubicin, cisplatin, and high-dose methotrexate with, or without, ifosfamide) was associated with a statistically significant improvement in overall survival in patients with newly diagnosed, high-grade, non-metastatic, resectable osteosarcoma. The pattern of outcome was generally similar in a small cohort of patients with metastatic disease who were enrolled in this trial. Mifamurtide is generally well tolerated; adverse events attributed to administration of the drug include chills, fever, headache, nausea, and myalgias. In the EU, mifamurtide is indicated in children, adolescents, and young adults for the treatment of high-grade, resectable, non-metastatic osteosarcoma after macroscopically complete surgical resection; it is administered by intravenous infusion in conjunction with postoperative multiagent chemotherapy. In the US, mifamurtide is currently an investigational agent that holds orphan drug status for the treatment of osteosarcoma.

Mefenorex or (+/-)N-(3-chloropropyl)-1-methyl-2-phenylethylamine is an N-alkylated analogue of amphetamine. The therapeutic efficacy of mefenorex as an adjunctive support in the treatment of obesity for limited periods of time, as well as its ability to be well tolerated, has been amply demonstrated. Mefenorex is considered to be racemic mixture, no available data regarding enantiospecific pharmacological activity of the compound.

Heteronium is an anticholinergic agent. As a bromide salt, it was investigated in the clinic for the treatment of peptic ulcer and other gastrointestinal disorders.

Methenolone (also known as primobolan) was described in 1960. Squibb Company began producing injectable drug in 1962. Methenolone originally was prescribed in case of muscle loss after operations, infections, long-term illnesses, aggressive therapy with corticoids or malnutrition, and in some cases it was used to treat osteoporosis and breast cancer. Methenolone was commonly used to promote weight gain in infants, weighing less than normal, without any side effects. Methenolone is an anabolic steroid, modification of dihydrotestosterone (DHT) with weak androgenic activity and a moderate anabolic effect. A notable trait of methenolone is that it can firmly bind to androgen receptors, stronger than testosterone. Adult doses for the treatment of aplastic anemia are usually in a range of 1–3 mg/kg per day. Adverse side effects include fluid and electrolyte retention, hypercalcaemia, increased bone growth and skeletal weight. In men, additional side priapism, azoospermia, hirsutism, male pattern baldness, acne andoedema. In women, side effects include virilization, amenorrhoea, menstrual irregularities, suppressed lactation, and increased libido. In children, side effects may include virilization symptoms. Metenolone may enhance effects of antidiabetics, ciclosporin, levothyroxine, warfarin. Resistance to the effects of neuromuscular blockers may occur, and metenolone also has the potential to interfere with glucose tolerance and thyroidfunction tests. Metenolone enanthate (methenolone enanthate) is an ester derivative of methenolone sold commonly under the brand names Primobolan (tablet form) orPrimobolan Depot (injectable). When it interacts with the aromatase enzyme it does not form any estrogens. It is used by people who are very susceptible to estrogenic side effects, having lowerestrogenic properties than nandrolone. This trait makes primobolan to be a good fat burner. Primobolan does not convert into estradiol. As an anabolic steroid, the use of metenolone is banned from use in sports governed by the World Anti-Doping Agency. Belarusian shot putter Nadzeya Ostapchuk was stripped of her gold medal after testing positive for metenolone at the London 2012 Olympic Games. She has been excluded from future IOC events. The NBA and NBPA also banned the use of methenolone under the Anti-Drug Program. In February 2013, Hedo Türkoğlu of the Orlando Magic was suspended for 20 games without pay by the league after testing positive for methenolone. In December 2013, Natalia Volgina was stripped of her 2013 Old Mutual Two Oceans Marathon title and received a two-year competition ban, subsequent to a final guilty verdict for using the steroid Metenolone.

Propicillin (Baycillin Mega) is this semisynthetic penicillin, analogous to penicillin V, was introduced in the early 1960s. Although it is better absorbed from the gastrointestinal tract, overall it is inferior to phenoxymethylpenicillin and phenoxyethylpenicillin because of its lower antibacterial activity. Propicillin is used by propicillin-susceptible pathogens in adults and adolescents from 14 years to treat mild to moderate bacterial infections. These include skin infections, ear, nose and throat infections (such as otitis media, sinusitis, tonsillitis, pharyngitis) and infections of the bronchi andlung inflammation. Moreover propicillin can for prevention and treatment of scarlet fever or against rheumatic fever are used (bacterial infection of the nose and throat). Even with tooth or jaw surgery the drug is used to treat an endocarditis endocarditis prevent. Its mechanism of action could be due to binding to specific penicillin-binding proteins (PBPs) located inside the bacterial cell wall, thus propicillin may inhibit the third and last stage of bacterial cell wall synthesis

Prenylamine, a slow Ca2+ channel blocker, was used to treat patients with angina pectoris, but because of the QT prolongation, this drug was withdrawn from the market. Prenylamine binds to calmodulin section and inhibits myosin light chain kinase.

Clorprenaline is a β2-adrenergic receptor agonist. As a bronchodilator it has been used for the treatment of bronchial asthma, bronchitis and other respiratory diseases. It is a potential new lean meat-boosting feed additive because it can promote animal muscular mass growth and decrease fat accumulation.
