Benzydamine (benzydamine hydrochloride, PHARIXIA®) is a benzyl-indazole having analgesic, antipyretic, and anti-inflammatory effects. It is indicated for the relief of pain in acute sore throat and for the symptomatic relief of oro-pharyngeal mucositis caused by radiation therapy.

Dipyrone, also known as Metamizole (INN), is an ampyrone sulfonate analgesic, antispasmodic and antipyretic. It was withdrawn from US market in 1977 on the basis of reports of agranulocytosis. Depyrone is still used to treat severe and diffucult for relieving pains of different origin; headache, tooth-ache, pains in the joints, muscles, following traumas and operations, gall and kidney colics, neurites, neuralgias, traumatic cerebrasthenia; inflammation of upper respiratory ways of microbial or virus origin; chorea; febrile states. Mechanism of action of dipyrone is complex. It is believed that dipyrone exerts its action by inhibiting COX-3, and activates opioid and cannabioid systems either itself, or by products of its metabolic degradation.

Nicoboxil is a nicotinate used in topical preparations as a rubefacient which has vasodilating properties mediated by prostaglandin. Nicoboxil is a component of finalgon® (nonivamid and nicoboxil), a topical cream for joint and muscle pains. The hyperaemic effect of Nicoboxil has an earlier onset and it is more intense than the nonivamide hyperaemic effect.

Lornoxicam (Xefo®) is a nonsteroidal anti-inflammatory drug of the oxicam class with analgesic, anti-inflammatory and antipyretic properties. It differs from other oxicam compounds in its potent inhibition of prostaglandin biosynthesis, a property that explains the particularly pronounced efficacy of the drug. The inhibition of the cyclooxygenase enzymes (COX-1 and COX-2) by lornoxicam (Xefo®) leads to desensitisation of peripheral nociceptors and consequently inhibition of inflammation. A central effect on nociception which seems to be independent of anti-inflammatory effects has also been suggested.

Tenoxicam (Mobiflex), an anti-inflammatory agent with analgesic and antipyretic properties, is used to treat osteoarthritis and control acute pain. The anti-inflammatory effects of tenoxicam may result from the inhibition of the enzyme cyclooxygenase and the subsequent peripheral inhibition of prostaglandin synthesis. As prostaglandins sensitize pain receptors, their inhibition accounts for the peripheral analgesic effects of tenoxicam. Antipyresis may occur by central action on the hypothalamus, resulting in peripheral dilation, increased cutaneous blood flow, and subsequent heat loss. Taking tenoxicam with other drugs can increase the chance of side effects or alter the therapeutic effect of tenoxicam or the other drug, depending on the combination. Drug types the tenoxicam may interact with include: other analgesic NSAIDs, salicylates such as aspirin, antacids, anticoagulants, cardiac glycosides, ciclosporin, quinolone antibiotics, lithium therapy, diuretics and anti-hypertensives, methotrexate, oral anti-diabetics, cholestyramine, dextromethorphan, mifepristone, corticosteroids, anti-platelet agents and selective serotonin reuptake inhibitors (SSRIs), tacrolimus, zidovudine, and gold/penicillamine. Tenoxicam is available as a prescription-only drug in the United Kingdom and other countries, but not in the US. Outside of the United Kingdom, tenoxicam is also marketed under brand names including Tilatil, Tilcitin, and Alganex. Tenoxicam belongs to the class of NSAIDs known as oxicams. It is used to relieve inflammation, swelling, stiffness, and pain associated with rheumatoid arthritis, osteoarthritis, ankylosing spondylitis (a type of arthritis involving the spine), tendinitis (inflammation of a tendon), bursitis (inflammation of a bursa, a fluid-filled sac located around joints and near the bones), and peri-arthritis of the shoulders or hips (inflammation of tissues surrounding these joints).

Clonixin is a nonsteroidal agent. It is an anilino-nicotinic acid derivative. It is a drug of anti-inflammatory antipyretic and analgesic activity that produces minor digestive side-effects. At high concentrations, clonixin inhibited PGE2 formed by COX-2 and partly by COX-1 activity. The drug is indicated for the relief of headaches, muscle aches, joint, dental, ear, dysmenorrhea, post-traumatic, post-surgical, gynecological. Adverse effects are occasionally nausea, dizziness, and somnolence, were mild and transient. On rare occasions, and administering high doses, it is possible the appearance of dry mouth or constipation. Concomitant use of anticholinergic drugs to be avoided by the possibility that they enhance their effects atropine.

Bendazac, (1-benzyl-1H-indazol-3-yl-oxy)-acetic acid, is structurally related to indomethacin. Its lysine salt has been reported to be absorbed better than the parent compound. It is applied topically as bendazac lysine 0.5% (wt/vol) aqueous solution for delaying the progression of cataract. Topical application of bendazac is associated with transient burning sensation. It reduces the secretion of the skin ulcer surface, promotes skin formation and accelerates tissue repair.

Epirizole (also known as Mepirizole) is a nonsteroidal anti-inflammatory drug developed for the treatment of such conditions as chronic rheumatoid arthritis. Although the drug was tested in a clinical trial, its current status is unknown and is supposed to be discontinued. Epirizole is known to be a duodenal ulcerogen, and its effect is mediated by generation of ROS.

Tetrydamine is a member of the indazol class of non-steroidal anti-inflammatory drugs. It is an analgesic and anti-inflammatory drug. Tetrydamine lavage reduced or eliminated all inflammation symptoms like burning, leucorrhea, etc. and resulted very well tolerated in vulvovaginitis, symptomatic bacterial vaginosis and cervicitis treatment.

TILIDINE is a low to medium potency opioid analgesic. It is metabolized to its active metabolites, nortilidine and bisnortilidine. Its analgesic activity is largely exerted through nortilidine which is a potent agonist at Mu opioid receptors.
