Mofebutazone (or monophenylbutazone) is a 3,5-pyrazolinedione derivative study for treating asthma and muscular pain. It was found that there was no increase in the incidence or severity of the asthmatic attacks during the course of mofebutazone treatment. The drug tended to improve the tested pulmonary ventilatory functions or at least to leave them unchanged. All the mofebutazone-treated individuals showed a dramatic reduction in the concentrations of PGE2, PGF2alpha, and LTs in their BAL, but there was no consistent correlation between the extent of reduction and the degree of benefit or worsening sustained by an individual patient. Mofebutazone was found to be excreted almost exclusively via the kidney

Nifenazone is a drug that has been used as an analgesic for a number of rheumatic conditions. Later it was shown that nifenazone is not of significant value in the therapy of the chronic rheumatic disorders and that side-effects may be expected to occur, particularly in those patients who give a history of abnormal reactions to phenylbutazone and oxyphenbutazone.

Aceclofenac is a non-steroidal anti-inflammatory drug (NSAID) analog of Diclofenac. It is used for the relief of pain and inflammation in rheumatoid arthritis, osteoarthritis and ankylosing spondylitis. The dose is 100 mg twice daily, and should not be given to people with porphyria or breastfeeding mothers and is not recommended for children. Aceclofenac is a cytokine inhibitor. Aceclofenac works by blocking the action of a substance in the body called cyclo-oxygenase. Cyclo-oxygenase is involved in the production of prostaglandins (chemicals in the body which cause pain, swelling and inflammation). Aceclofenac is the glycolic acid ester of diclofenac. The incidence of gastric ulcerogenicity of aceclofenac has been reported to be significantly lower than that of other frequently prescribed NSAIDs: for instance, 2-fold less than naproxen, 4-fold less than diclofenac, and 7-fold less than indomethacin. Aceclofenac is metabolized in human hepatocytes and human microsomes to form [2-(2',6'-dichloro-4'-hydroxy- phenylamino)phenyl] acetoxyacetic acid as the major metabolite, which is then further conjugated.

Fentiazac is a non-steroidal anti-inflammatory agent developed for the treatment of pain disorders. The drug was marketed under the name Norvedan, however, its current marketing status is unknown and supposed to be "discontinued".

Idrocilamide (trade names Talval, Srilane, Relaxnova, Brolitène) is a medication with skeletal muscle relaxant[2] and anti-inflammatory actions used as a topical cream to treat lumbago and other kinds of muscular pain. Idrocilamide acts intracellularly by decreasing sarcoplasmic reticulum calcium release and externally by facilitating the voltage-dependent inactivation of the voltage sensor for excitation-contraction coupling. Idrocilamide has been reported to be a potent inhibitor of the metabolism of caffeine. Idrocilamide is available on prescription or over-the-counter in France and various other countries. Idrocilamide exerts a direct depressant effect on mechanical tension in rat soleus muscle fibers.

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.

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.

Capsaicin is a topical analgesic that is FDA approved for the treatment of neuropathic pain associated with postherpetic neuralgia. Capsaicin is most often used as a topical analgesic and exists in many formulations of cream, liquid, and patch preparations of various strengths; however, it may also be found in some dietary supplements. Capsaicin is a naturally-occurring botanical irritant in chili peppers, synthetically derived for pharmaceutical formulations. Capsaicin is an agonist for the transient receptor potential vanilloid I receptor (TRPVI), which is an ion channel-receptor complex expressed on nociceptive nerve fibers in the skin. Common adverse reactions include erythema, rash, pruritus, nausea.

Dexketoprofen is a nonsteroidal anti-inflammatory drug (NSAID), manufactured by Menarini under the tradename Keral. Dexketoprofen is indicated for short-term treatment of mild to moderate pain, including dysmenorrhoea. Dexketoprofen works by blocking the action of a substance in the body called cyclo-oxygenase, which is involved in the production of chemicals in the body called prostaglandins. Prostaglandins are produced in response to injury or certain diseases and would otherwise go on to cause swelling, inflammation, and pain. By blocking cyclo-oxygenase, dexketoprofen prevents the production of prostaglandins and therefore reduces inflammation and pain. Along with peripheral analgesic action, it possesses central analgesic action. Dexketoprofen may cause dizziness, and patients should not, therefore, drive or operate heavy machinery or vehicles until they are familiar with how dexketoprofen affects them. Concomitant use of alcohol and other sedatives may potentiate this effect. In a small subset of individuals, the dizziness may be intolerable and require the transition to an alternative treatment.

Oxyphenbutazone is a non-steroidal anti-inflammatory drug, cyclooxygenase (prostaglandin synthetase) inhibitors which was marked under brand name tandearil for the treatment rheumatic disorders such as ankylosing spondylitis, osteoarthritis, and rheumatoid arthritis. But this drug was withdrawn from markets due to bone marrow suppression.
