tolfenamic-acid and proquazone

The analgesic effect of 10 anti-inflammatory drugs was compared using a single-blind method in 90 patients with rheumatoid arthritis. Each patient received two different drugs, for three days each and each drug was evaluated in 18 patients. After the trial, the patients considered which of the drugs they preferred. The greatest relief from pain was achieved by diclofenac, indomethacin, naproxen and tolfenamic acid, each of these being preferred by the majority of patients and being significantly (p less than 0.01) better than the least effective drugs ketoprofen and proquazone. Acetylsalicylic acid, azapropazone, carprofen and ibuprofen were considered intermediate in efficacy.

The effects of one-day treatment with nine nonsteroidal anti-inflammatory drugs and prednisolone on human synovial fluid concentrations of prostanoids were studied. The doses were calculated so as to be approximately equipotent according to clinical experience and the recommendations of the manufacturers. Most of the drugs used reduced clearly PGE2 and TxB2 levels in synovial fluid, but only a slight diminution in 6-keto-PGF1 alpha values was found. Carprofen, diclofenac, indomethacin, naproxen and tolfenamic acid reduced significantly the synovial fluid PGE2 concentrations. Diclofenac and indomethacin also reduced significantly the synovial TxB2 concentrations.

The effect of 9 nonsteroidal anti-inflammatory drugs on the renal excretion of uric acid was studied in patients with normal renal function. Diflunisal, Azapropazone and Indomethacin caused an increase and Piroxicam a decrease in the uric acid excretion. Other drugs studied had no significant influence.
