[Comparative clinical study of tiaprofenic acid and lysine acetylsalicylate in aged osteoarthrosis patients]. / Studio clinico di confronto tra acido tiaprofenico e acetilsalicilato di lisina in pazienti anziani osteoartrosici.

Thirty elderly patients (mean age 74) with osteoarthritis effecting various joints were treated with an oral suspension of either tiaprofenic acid (TA) (600 mg per diem b.i.d.) or lysine acetyl salicylate (1800 mg per diem b.i.d.) for 3-6 months in an open randomized experimental study. The parameters of efficacy assessed were pain at rest and under load, stiffness, ability to perform a pre-selected daily exercise and joint movements hampered by the disease. Blood flow, liver and kidney function and side effects were examined on a monthly basis. The tiaprofenic acid proved more effective in reducing pain and aiding functional recovery and was also better tolerated, especially at gastrointestinal level. Nine patients under lysine acetyl salicylate and 2 under tiaprofenic acid were forced to suspend treatment due to pyrosis, epigastralgia ed dyspepsia.

Double-blind placebo-controlled study of the efficacy and tolerability of suprofen suppositories in patients with osteoarthritic pain.

In a placebo-controlled double-blind trial analgesic effectiveness and tolerability of alpha-methyl-4-(2-thienyl-carbonyl)phenylacetic acid (suprofen, Suprol) 300 mg suppositories were evaluated for 45 informed patients suffering from chronic pain due to osteoarthritis; the subjects were treated rectally, t.i.d., for 10 days. Suprofen proved to be statistically significantly superior to placebo in all the variables considered for evaluation of the analgesic effect, i.e., pain intensity and relief scores, sum of pain intensity differences (SPID), total pain relief (TOTPAR), global assessments by investigator and patient. In particular, the efficacy of suprofen was judged by the physician good or very good in 86.3% of the patients. Similar frequencies of rectal side-effects were observed in both treatment groups, with slightly but not significantly higher incidence in the group treated with suprofen. Haematologic and clinical chemistry laboratory tests showed no statistically significant alterations due to the treatment.
