Chlormidazole was the first azole introduced the treatment of topical mycosis. It demonstrated inhibitory activity against many fungi and some gram-positive cocci. It is used for the treatment of fungal and bacterial infections of nails and skin, including interdigital and periungual mycoses. Possible side effects are: local skin irritation, burning, itching.

Limaprost alfadex, an oral prostaglandin E1derivative, jointly developed by Ono Pharmaceutical Co., Ltd. (Ono) and Dainippon Pharmaceutical Co., Ltd. (Dainippon), was approved in 1988 with an indication for treatment of various ischemic symptoms such as ulcer, pain and sensation of coldness of the hands and feet associated with thromboangiitis obliterans. This product has since been marketed by the two companies under two independent brands (Ono: OPALMON Tablet; Dainippon: PRORENAL Tablet). The two companies have jointly sought since 1991 to further expand the indication of limaprost for the treatment of lumbar spinal canal stenosis, based on the report that limaprost improved blood flow not only of limbs but of blood vessels supplying nutrition to the cauda equina, a mass of spinal nerves extending within lumbar spinal canal. With the efficacy and safety successfully confirmed by the two companies' research efforts, limaprost was approved on April 4, 2001 for "improvement in subjective symptoms (pain and numbness in lower limbs) and walking ability, which accompany acquired lumbar spinal canal stenosis (patients who show bilateral intermittent claudication but with normal Straight Leg Raising (SLR) test)." No other agent has ever obtained approval for this indication, either in Japan or abroad. Since lumbar spinal canal stenosis is mainly observed among the elderly people, the number of patients suffering from the disease is anticipated to increase as the population ages. Age-related changes in a bone (deformation of intervertebral joints and vertebra) and/or hypertrophy of the ligaments that cover the inner wall of the spinal canal contribute to a narrowing of the lumen of the lumbar spinal canal. Such a narrowed lumen contributes to poor blood circulation of the cauda equina, leading to lack of nutrition in the area and eventually resulting in neurologic functional impairment. As a result, pain and numbness are caused in lower limbs, which consequently lead to difficulty in walking (intermittent claudication) in many cases. In 2011, Ono and DSP initiated Phase II clinical trials in Japan for the treatment of carpal tunnel syndrome. In 2013, these trials were discontinued because the study failed to demonstrate efficacy. Ono and DSP also discontinued the development of limaprost alfadex for the additional indication of cervical spondylosis in 2008 due to the failure to demonstrate the anticipated efficacy in a Phase II study in patients with the disease. However, it was verified by Seoul National University Hospital in November of 2014 that the study on the efficacy of oral limaprost alfadex after surgery for cervical myelopathy was still ongoing. Limaprost alfadex has been shown to improve peripheral circulatory failure with a vasodilator action and an antithrombotic effect. It also improves poor blood flow in the nerve tissue in cervical spondylosis and normalizes nerve function. One of the pharmacological action of limaprost is the suppression of NGF expression in human cells.

Acemetacin is a non-steroidal anti-inflammatory drug used for the treatment of osteoarthritis, rheumatoid arthritis, lower back pain, and relieving post-operative pain. It is manufactured by Merck KGaA under the tradename Emflex and is available in the UK as a prescription-only drug. Other brand names for acemetacin include Rheutrop (Austria), Acemetadoc, Acephlogont, Azeat, Rantudil (Germany, Hungary, Mexico, Portugal, Turkey), Gamespir (Greece), Oldan, Reudol (Spain), Tilur (Switzerland), Ost-map (Egypt). Acemetacin is a glycolic acid ester of indomethacin. The pharmacological activity resulting from acemetacin administration in man is derived from the presence of both acemetacin and indomethacin. The precise pharmacological mode of action of acemetacin is not known. However, unlike other NSAIDs, acemetacin is only a relatively weak inhibitor of prostaglandin synthetase. Prostaglandins are known to have an antisecretory and cytoprotective effect on the gastric mucosa. Acemetacin shows activity in many of the established in vitro tests of anti-inflammatory activity including inhibition of the release of a number of mediators of inflammation. Acemetacin is well absorbed after oral administration. Its major metabolite is indomethacin, which, after repeated administration is present at levels in excess of those of acemetacin. Acemetacin is bound to plasma protein to a slightly lesser extent than indomethacin and has a relatively short plasma elimination half-life. It is eliminated by both hepatic and renal mechanisms. The pharmacokinetics appear to be linear at recommended therapeutic doses, unaffected by moderate renal or hepatic impairment, and unchanged in the elderly.

Clofoctol [2-(2,4-dichlorobenzyl)-4-(tetramethyl-1,1,3,3-butyl)phenol] is a synthetic antibacterial agent with bactericidal activity on various Gram-positive (especially S. pyogenes and S. pneumoniae, but also Corynebacterium spp. and Propionibacterium acnes) and some Gram-negative bacteria (including Haemophilus influenzae, Bordetella spp., Neisseria meningitides, and Neisseria gonorrhea). A peculiar property of clofoctol is the rapidity of the antimicrobial effect, similar to that of antiseptic compounds, which makes the development of resistance less likely. Following rectal administration of clofoctol, absorption is rapid and nearly complete (about 98%), with a good penetration in the lung tissue. Clofoctol is primarily metabolized by hepatic glucuronidation and excreted through the biliary system; renal elimination is negligible. Clofoctol compound has been used mainly in France (under the trade name Octoplus ) and Italy (as Gramplus) for the treatment of mild upper respiratory tract infections, especially in pediatric patients

Mizolastine (Mizollen) is a long-acting H1 -antihistamine indicated for the symptomatic relief of seasonal allergic rhinoconjunctivitis (hay fever), perennial allergic rhinoconjunctivitis and urticaria. It blocks H1 receptors and is commonly fast-acting. It does not prevent the actual release of histamine from mast cells, just prevents it binding to receptors. Side effects can include dry mouth and throat

Proglumide is a drug that inhibits gastrointestinal motility and reduces gastric secretions. It acts as a cholecystokinin antagonist, which blocks both the CCKA and CCKB subtypes. It was used mainly in the treatment of stomach ulcers, although it has now been largely replaced by newer drugs for this application. An interesting side effect of proglumide is that it enhances the analgesia produced by opioid drugs, and can prevent or even reverse the development of tolerance to opioid drugs. This can make it a useful adjuvant treatment to use alongside opioid drugs in the treatment of chronic pain conditions such as cancer, where opioid analgesics may be required for long periods and development of tolerance reduces clinical efficacy of these drugs.

Pimethixene is an antihistamine exerting sedative and antitussive properties. Pimethixene displayed high affinity to serotonin 5-HT2A and 2B, histamine H1 and muscarinic acetylcholine M2 receptors. Oral pimethixene used to calm dry cough and irritation coughs in children.

Laninamivir ocatanoate is a prodrug of Laninamivir (R-125489), a new neuraminidase (NA) inhibitor, was discovered, and in this study, its NA inhibitory activities against various influenza viruses including oseltamivir-resistant viruses are reported. Laninamivir octanoate has been approved for use in Japanese clinics for the treatment and prevention of influenza in both adults and children. The inhaled laninamivir octanoate is converted into its active form, laninamivir, in the lungs where a high concentration persists for a long period of time.

Pentifylline is an active vasodilating substance which does not affect blood sugar levels. Pentifylline inhibits the soluble and the particulate cyclic AMP phosphodiesterases from bovine platelets and rat brain ATPase. The inhibition of ATPase by pentifylline was not influenced by the change in Na /K ratio. Pentifylline in combination with Nicotinic acid indicated for the treatment of Cerebral circulatory disorders and Circulatory disorders of the eye. Pentifylline is well tolerated but it is recommended that blood pressure be monitored and if there is a severe drop in blood pressure, a drip infusion of plasma expander be administered. Coagulation states should also be closely watched.

Bamipine (trade name Soventol) is a sedating antihistamine with pronounced sedative effects. Bamipine is a pharmaceutical drug acting as an H1 antihistamine with anticholinergic properties. It is used as an antipruritic ointment. Bamipine hydrochloride has been given by mouth. Bamipine, bamipine lactate, and bamipine salicylate have all been applied topically.
