Parmidin (pyridinol carbamate) is a Soviet drug, has anti-arteriosclerotic (increased vascular resistance) activity, reduces the permeability of blood vessels, it helps to restore disturbed microcirculation in pathological processes. This is mainly due to the influence on kinin system, especially with a decrease in the activity of bradykinin receptors. It also reduces the aggregation of platelets. It’s used to treat: the brain vascular atherosclerosis, heart, limbs; diabetic retinopathy (non-inflammatory lesion of the retina associated with increased levels of sugar in the blood); thrombosis (violation of patency) retinal vein; occlusive disease (inflammation of the inner lining of arteries with a decrease in their lumen); trophic leg ulcers (slow-healing skin defects caused by malnutrition). Ointment is used in neurodermatitis (skin disease caused by disturbance of the central nervous system), Lichen sclerosus (teardrop scleroderma) genital organs of children, as well as a prophylactic and therapeutic agent against radiation skin lesions.

Febarbamate is a derivative of barbituric acid and carbamate, used for the treatment of generalized anxiety and alcohol withdrawal syndrome. The drug was marketed in Europe in the 1980s as a single agent or in combination with difebarbamate and phenobarbital, but it was later withdrawn from the market because of the potential risk of liver damage.

Carboquone (CQ) is an anticancer alkylating agent synthesized and developed by Arakawa et al. (Sankyo Co, Ltd.) in 1970, having chemical structure, 2,5-bis-(1-aziridinyl)-3-(2-carbamoyloxy-1-methoxyethyl)-6-methyl- 1,4- benzoquinone. The antitumor efficacies of CQ were reported as excellent, however, the side effects are considerably strong. Carboquone is used to treat various forms of cancer. It is indicated for the treatment of metastatic testicular tumors, metastatic ovarian tumors and advanced bladder cancer.

Carumonam is a monobactam antibacterial agent. It was highly active in vitro against members of the family Enterobacteriaceae, Pseudomonas aeruginosa, and Haemophilus influenzae and weakly active against Streptococcus pneumoniae, but it was not active against Staphylococcus aureus. The excellent activity of carumonam against Gram-negative bacteria is related to its high affinity for their penicillin-binding proteins. It is indicated for the treatment of urinary tract infections, chronic respiratory infections, biliary tract infections, peritonitis, sepsis. Another factor that contributes to the excellent activity of carumonam against Gram-negative bacteria is its resistance to beta-lactamases. Adverse effects of the carumonam were limited to phlebitis at the intravenous infusion site; bloody diarrhea.

Albendazole oxide (Ricobendazole) is a methylcarbamate benzimidazole with a broad-spectrum anthelmintic activity. Ricobendazole is a key metabolite of albendazole. Ricobendazole has broad spectrum anthelmintic action; the drug is active against adult and immature nematodes (Dictyocaulus, Haemonchus, Ostertagia, Thelazia, Trichostrongylus, Nematodirus, Cooperia, Oesophagostomum, Bunostomum, Chabertia etc.), tapeworms (Moniezia, Avitellinae, Thysaniezia etc.), as well as adult flukes (Fasciola, Paramphistom, and Dicrocoelium), having an egg-killing effect; it reduces pasture contamination with helminth eggs. The mechanism of action of ricobendazole (albendazole sulfoxide), ensuring its anthelmintic activity, is associated with selective inhibition of beta-tubulin polymerization, which leads to the destruction of cytoplasmic microtubules of helminth intestinal cells; it inhibits the processes of glucose transport and disposal, and inhibits the synthesis of ATP; it blocks the movement of secretory granules and other organelles in the muscle cells of worms, disrupting the permeability of cell membranes and muscle innervation, which causes paralysis and death of the parasites. Albendazole oxide has been shown to induce apoptosis in human cancer cell line HT-29, possibly by arresting the cell cycle at the G2/M phase.

Cloforex (Oberex) is an anorectic of the amphetamine class. It is a prodrug to chlorphentermine. It is an appetite-reducing agent, used to treat obesity. The Ministry of Health withdrew preparations containing cloforex as a precautionary measure pending scientific evidence of a relationship between their use and the development of pulmonary hypertension. In Europe Cloforex was approved in 1968 and discontinued in 1969.

Ronidazole is an antiprotozoal agent. Ronidazole and the other nitroimidazole derivatives damage DNA following reduction of the nitro group. It is used in veterinary for prevention and treatment of various infections including histomoniasis in turkeys, trichomoniasis in pigeons, genital trichomoniasis in cattle, haemorrhagic enteritis in pigs and Tritrichomonas foetus in cats.

Phenprobamate (3-phenylpropylcarbamate, Gamaquil, Isotonil) is a centrally acting muscle relaxant with mild sedative and anticonvulsant effects. Muscle relaxants can enhance and prolong the effect of narcotic drugs and enable to obtain same effect with a smaller amount of alcohol or illicit substance. Almost all of the centrally acting muscle relaxants have varying sedative effects on which their abuse potential mainly depends. Overdose is similar to barbiturates. Its mechanism of action is probably similar to meprobamate. Phenprobamate was previously used in humans as an anxiolytic, and is still sometimes used in general anesthesia and for treating muscle cramps and spasticity. Phenprobamate is still used in some European countries, but it has generally been replaced by newer drugs. Phenprobamate is metabolized by oxidative degradation of the carbamate group and ortho-hydroxylation of the benzene ring, and is eliminated in urine by the kidneys. Doses range from 400 to 800 mg, up to 3 times a day.

Hexapropymate, a hypnotic/sedative drug that was available without prescription in Belgium under the trade name Merinax for the treatment of insomnia. Poisoning with hexapropymate was a serious condition that required symptomatic treatment in the intensive care unit. As a result, the drug was substituted by newer agents with improved safety profiles.
