Beg, M A published the artcileSafety of tienilic acid., Category: benzothiophene, the main research area is .

The safety and efficacy of tienilic acid have been evaluated in studies of patients with mild to moderate essential hypertension, salt and water retention states and hyperuricaemia associated with gout. During the course of these studies 675 patients were treated with tienilic acid, 310 were treated with hydrochlorothiazide, 43 were treated with probenecid and 34 were treated with placebo. Overall, adverse reactions characterized as probably drug-related or questinably drug-related were reported in 28% of patients treated with tienilic acid, 24% treated with hydrochlorothiazide, 25% of patients treated with probenecid and 33% treated with placebo. The side effects encountered were mild in severity, reversible and represented extensions of the pharmacological activity of tienilic acid, hydrochlorothiazide and probenecid. These initial studies demonstrate that tienilic acid is safe and effective in the treatment of mild to moderate essential hypertension, salt and water retention states, including oedema associated with congestive cardiac failure or mild to moderate renal dysfunction, and in the management of elevated serum uric acid levels associated with gout.

Frohlich, E D published the artcileAntihypertensive and renal effects of tienilic acid., SDS of cas: 40180-04-9, the main research area is .

Tienilic acid, a diuretic agent effective at the cortical diluting segment of the distal tubule, has been found to have equivalent antihypertensive action in a dose of 250 mg twice daily to hydrochlorothiazide in a dose of 50 mg twice daily. Tienilic acid reduced arterial pressure without diminishing renal plasma flow or endogenous creatinine clearance; moreover, it did so whilst achieving hypouricaemia through a uricosuric effect. Hypokalaemia was observed but corrected by supplemental potassium. A transient but reversible, slight elevation in serum creatinine concentration and significant hypertriglyceridaemia were also observed. In conclusion, tienilic acid seems to be a novel diuretic, well-suited for the patient with hypertension, particularly if there is coincidental gout or coexisting hyperuricaemia.

Pearson, R M published the artcilePropranolol and tienilic acid in essential hypertension., Quality Control of 40180-04-9, the main research area is .

Sixteen patients with moderately severe essential hypertension completed a double-blind crossover trial with four treatment periods each lasting for six weeks. They received in random order, placebo; tienilic acid 250 mg/day; propranolol 80 mg b.d.; and tienilic acid 250 mg/day and propranolol 80 mg b.d. in combination. Mean blood pressure in the lying position was 169/98 mmHg on placebo, 157/94 mmHg on tienilic acid, 159/90 mmHg on propranolol and 142/86 mmHg on the combination of tienilic acid and propranolol. The effects of tienilic acid and propranolol on blood pressure were additive and there was no evidence of any interaction. The onset of the hypotensive effect of tienilic acid was gradual while the effect of propranolol was maximal within 2 weeks of the start of treatment. Tienilic acid produced a significant reduction in serum urate from 0.33 mmol/l to 0.18 mmol/l. The combination of tienilic acid and propranolol in the doses used in the trial was effective and acceptable in the reduction of raised blood pressure.

Morgan, A published the artcileThe use of tienilic acid in nephrotic syndrome: a clinical study., Application In Synthesis of 40180-04-9, the main research area is .

The diuretic and uricosuric activities of tienilic acid 250–50 mg daily over a minimum six week period have been studied in seven patients with the nephrotic syndrome secondary to glomerulonephritis proven by renal biopsy. Tienilic acid failed to control oedema in one patient who had to be withdrawn. In the six other patients a hypouricaemic effect with increased urate clearance was noted. No consistent effects were noted with respect to the serum cholesterol and triglyceride concentrations. No side effects were observed. It is concluded that in nephrotic patients tienilic acid behaves as a mild diuretic with consistent hypouricaemic and uricosuric effects.

Andersson, O published the artcileTienilic acid in mild to moderate hypertension., Computed Properties of 40180-04-9, the main research area is .

Tienilic acid has blood pressure lowering properties alone and in combined treatment with beta-adrenergic blocking agents; 250 mg of tienilic acid seems to correspond to 50 mg of hydrochlorothiazide. Tienilic acid effectively reduces serum urate and has no marked or rapid effect on potassium balance. During short-term treatment, no impairment of glucose tolerance was found.

Okun, R published the artcileA double-blind study of tienilic acid with two year follow-up of patients with mild to moderate essential hypertension., Application In Synthesis of 40180-04-9, the main research area is .

In a double-blind study, thirty patients having mild to moderate essential hypertension were randomly assigned to a six week regimen of either tienilic acid, hydrochlorothiazide, or placebo. Blood pressure was significantly reduced with tienilic acid and hydrochlorothiazide although more so with tienilic acid. Serum uric acid declined strikingly with tienilic acid and increased significantly with hydrochlorothiazide. Serum potassium declined slightly with tienilic acid but more so with hydrochlorothiazide. Serum creatinine and blood urea nitrogen increased slightly more with tienilic acid than with hydrochlorothiazide. There were no clinical adverse effects to any of the medications during this study. Twenty-four months of continuous administration of tienilic acid revealed maintenance of blood pressure effect, but with slight increases in blood urea nitrogen, serum creatinine and uric acid and slight decreases in serum potassium as compared to six weeks administration. Tienilic acid appears to be a useful new antihypertensive agent. The hypouricaemic effect is profound and strongly suggests the need for continuing evaluation of this compound because of its unique combination of diuretic, antihypertensive and hypouricaemic properties.

Noble, R E published the artcileLong-term usage of tienilic acid in essential hypertension., HPLC of Formula: 40180-04-9, the main research area is .

The purpose of this double-blind study was to compare the effects on blood pressure of tienilic acid and hydrochlorothiazide in patients with essential hypertension. The biochemical effects of tienilic acid in relation to those of hydrochlorothiazide were also determined over a long-term period of therapy. Sixty-six outpatients with mild to moderate essential hypertension were treated for seven months with either 250 mg of tienilic acid or 50 mg of hydrochlorothiazide after a 3 week placebo period. When warranted, dosage was increased to a maximum of 500 mg of tienilic acid and 100 mg of hydrochlorothiazide daily. Results indicate that tienilic acid reduced blood pressure significantly and to the same extent as hydrochlorothiazide. No significant side effects were observed. The effects on potassium, blood urea nitrogen and creatinine were comparable in both groups. However, serum uric acid rose with hydrochlorothiazide but fell with tienilic acid. In view of this effect, tienilic acid may have certain advantages over thiazide therapy in the treatment of hypertension.

Zimmerman, H J published the artcileTicrynafen-associated hepatic injury: analysis of 340 cases., Related Products of benzothiophene, the main research area is .

Ticrynafen, a uricosuric diuretic, was withdrawn from clinical use in the United States in 1980 after having been implicated as the cause of a number of instances of serious hepatic injury. In this report, we analyze 340 cases of ticrynafen-associated hepatic disease reported to the manufacturer from the time of initial marketing until shortly after the drug had been recalled. Jaundice was recorded in 246 of 287 patients with sufficient clinical information, and 25 (10.2%) of these icteric patients died. The high levels of serum aminotransferase and the case fatality rate are consistent with the hepatocellular injury that was evident in all of the histologic material. In three-fourths of the cases available to us for histologic study, the lesion was that of acute hepatocellular injury. In the remaining cases there was evidence of chronic active hepatitis and/or cirrhosis. Comparison of demographic characteristics of the total population exposed to ticrynafen with the subset developing hepatic injury suggests a proportionately higher risk of injury for females over the age of 60 years. The variable and unusually prolonged latent period and lack of reported eosinophilia or rash generally suggest a mechanism other than hypersensitivity. However, the recurrence of hepatic injury in 15 of the 16 patients challenged with the drug and the prominence of eosinophils in hepatic tissue in some of the cases suggests that hypersensitivity may also play a pathogenetic role. Accordingly, there is reason to incriminate both metabolic idiosyncrasy and hypersensitivity in the mechanism of injury.

Homberg, J C published the artcileDrug-induced hepatitis associated with anticytoplasmic organelle autoantibodies., Recommanded Product: 2-(2,3-Dichloro-4-(thiophene-2-carbonyl)phenoxy)acetic acid, the main research area is .

A study from five hepatology units documenting 157 cases of drug-induced hepatitis and a second study from a laboratory of immunology which tested more than 100,000 sera permitted us to establish the frequency of antiorganelle antibodies and their diagnostic value in drug-induced hepatitis. In drug-induced hepatitis caused by a heterogenous group of drugs consisting of ajmaline, aminopterine, isaxonine, isoniazid, perhexiline, phenylbutazone and troleandromycine, antiorganelle antibodies were absent or rare. In drug-induced hepatitis caused by another heterogenous group of drugs, including clometacin, fenofibrate, oxyphenisatin and papaverine, antismooth muscle, antinucleus and antimitochondria antibodies were found in isolation or in different combinations in 70% of cases. From the presence of antismooth muscle antibodies in sera, we could trace 30 cases of clometacin-induced hepatitis. The third group included drug-induced hepatitis with special antibody:iproniazid-induced hepatitis with antimitochondrial antibody 6 and tienilic acid (ticrynafen)-induced hepatitis with antiliver/kidney microsome antibody 2 (anti-LKM2). These two antibodies are rare in routine sera and were absent in patients who received the drug and had no liver damage. From the presence of corresponding antibodies, we detected six cases of iproniazid-induced hepatitis and 67 cases of tienilic acid-induced hepatitis. Antiorganelle antibodies found in high titers disappeared in 2 to 24 months following withdrawal of the offending drug. The fourth group was represented by halothane-induced hepatitis; antiliver/kidney microsome antibody 1 was weak and infrequent. Similarities between drug-induced hepatitis of the second group and lupoïd hepatitis suggest that drugs may reveal this spontaneous disorder.(ABSTRACT TRUNCATED AT 250 WORDS)
