Prenoxdiazine under the brand name Libexin is used as an antitussive agent. It was shown, that the use of this drug for pregnant women with an unproductive cough could be beneficial.

Faropenem is a unique antimicrobial penem being developed for oral administration. It markets it in two forms: faropenem sodium and faropenem medoxomil. The high binding affinities of faropenem to penicillin-binding proteins from gram-negative and gram-positive bacteria are mirrored by its pronounced and concentration-dependent bactericidal effect. It is usually used to treat a wide range of infections such as skin, respiratory and otorhinologic infections. The most commonly reported adverse reactions include diarrhea, abdominal pain, loose stool, rash and nausea. The FDA refused to approve faropenem – the applicant have to conduct new studies and clinical trials to prove the drug treats community-acquired pneumonia, bacterial sinusitis, chronic bronchitis, and skin infections.

Cefmatilen (codenamed S-1090) is an orally-active cephalosporin antibiotic, that shows high activity against a variety of Gram-positive and Gram-negative bacteria, including Streptococcus pyogenes and Neisseria gonorrhoeae.

Minodronic acid (RECALBON®, Bonoteo®), a third-generation bisphosphonate, was approved in Japan for the oral treatment of osteoporosis. This drug increases the bone mineral density and the strength by inhibiting osteoclastic bone resorption. Nitrogen-containing bisphosphonates, such as minodronic acid (RECALBON®, Bonoteo®) induce osteoclast apoptosis by inhibiting farnesyl pyrophosphate synthase (FPPS), a key enzyme in the mevalonate pathway. Inhibition of FPPS in osteoclasts prevents the biosynthesis of isoprenoid lipids that are required for the prenylation of small GTPase signaling proteins necessary for osteoclast function. Similarly, nitrogen-containing bisphosphonates have been shown to inhibit farnesyl pyrophosphate/geranyl pyrophosphate synthase activity.

Enviomycin, antimicrobial drug, was isolated in Japan from fermentation broth of Syteptomyces griseoverticillatus var tuberacticus. This drug, a water-soluble, basic peptide, is effective against tubercle bacilli as well as some gram-positive and gram-negative bacteria. It is related to viomycin and cepreomycin in some of its physicochemical properties. It is used for the treatment of Mycobacterium avium caused lung diseases.

Egualen is an azulene derivative developed for the treatment of peptic ulcer and marketed in Japan under the tradename Azuloxa. The drug exerts its antiulcer activity by antagonizing TXA2 production.

Ecabet is an anti-ulcer agent, marketed in Japan as an oral agent for treatment of gastric ulcers and gastritis. Ecabet eradicates Helicobacter pylori infection in gastric ulcer patients. Antibacterial effect of ecabet is demonstrated at low pH, is mediated by inhibition of bacterial urease and accompanied by interference with TLR4 signaling and pepsin inhibition. Ecabet is also investigated for the treatment of dry eye syndrome.

Sarpogrelate (brand name Anplag; former developmental code names MCI-9042, LS-187,118) is a drug which acts as an antagonist at the 5HT2A and 5-HT2B receptors. It blocks serotonin-induced platelet aggregation and has applications in the treatment of many diseases including diabetes mellitus, Buerger's disease, Raynaud's disease, coronary artery disease, angina pectoris, and atherosclerosis.

Aluminum gluconate is added to an electrolytic solution for an electrolytic capacitor, the dissolution of aluminum cathode foil caused by high-temperature.

Olamufloxacin (HSR-903) is an oral fluoroquinolone antimicrobial agent which has been reported to have a potent activity against respiratory pathogens, such as Streptococcus pneumoniae, Haemophilus influenzae, Moraxella catarrhalis, Klebsiella pneumoniae, Staphylococcus aureus, Chlamydia spp. and Legionella spp., as well. Olamufloxacin inhibits DNA gyrase from the susceptible and resistant bacterial strains. It has been shown that olamufloxacin possesses a more potent antibacterial activity against potential respiratory pathogens compared with other quinolone derivatives. An oral formulation of olamufloxacin was undergoing phase III for Bacterial infections in Japan (Discontinued).
