Flexyx drugs: Sklero-tabuls

Sklero-tabuls - General Information:

A fibric acid derivative used in the treatment of hyperlipoproteinemia type III and severe hypertriglyceridemia. (From Martindale, The Extra Pharmacopoeia, 30th ed, p986)

Pharmacology:

Sklero-tabuls is an antilipidemic agent similar to gemfibrozil. It acts to lower elevated serum lipids by reducing the very low-density lipoprotein fraction (S_f 20-400) rich in triglycerides. Serum cholesterol may be decreased, particularly in those patients whose cholesterol elevation is due to the presence of IDL as a result of Type III hyperlipoproteinemia. Several investigators have observed in their studies that clofibrate may produce a decrease in cholesterol linoleate but an increase in palmitoleate and oleate, the latter being considered atherogenic in experimental animals. The significance of this finding is unknown at this time. Reduction of triglycerides in some patients treated with clofibrate or certain of its chemically and clinically similar analogs may be associated with an increase in LDL cholesterol. Increase in LDL cholesterol has been observed in patients whose cholesterol is initially normal. Animal studies suggest that clofibrate interrupts cholesterol biosynthesis prior to mevalonate formation.

Sklero-tabuls for patients

Sklero-tabuls Interactions

Caution should be exercised when anticoagulants are given in conjunction with Atromid-S. Usually, the dosage of the anticoagulant should be reduced by one-half (depending on the individual case) to maintain the prothrombin time at the desired level to prevent bleeding complications. Frequent prothrombin determinations are advisable until it has been determined definitely that the prothrombin level has been stabilized.

Atromid-S may displace acidic drugs such as phenytoin or tolbutamide from their binding sites. Caution should be exercised when treating patients with either of these drugs or other highly protein-bound drugs and Atromid-S. The hypoglycemic effect of tolbutamide has been reported to increase when Atromid-S is given concurrently.

Fulminant rhabdomyolysis has been seen as early as three weeks after initiation of combined therapy with another fibrate and lovastatin but may be seen after several months. For these reasons, it is felt that, in most subjects who have had an unsatisfactory lipid response to either drug alone, the possible benefits of combined therapy with lovastatin and a fibrate do not outweigh the risks of severe myopathy, rhabdomyolysis, and acute renal failure. While it is not known whether this interaction occurs with fibrates other than gemfibrozil, myopathy and rhabdomyolysis have occasionally been associated with the use of fibrates alone, including clofibrate. Therefore, the combined use of lovastatin with fibrates should generally be avoided.

Sklero-tabuls Contraindications

Clofibrate is contraindicated in pregnant women. While teratogenic studies have not demonstrated any effect attributable to clofibrate, it is known that serum of the rabbit fetus accumulates a higher concentration of clofibrate than that found in maternal serum, and it is possible that the fetus may not have developed the enzyme system required for the excretion of clofibrate.

It is contraindicated in patients with clinically significant hepatic or renal dysfunction. Rhabdomyolysis and severe hyperkalemia have been reported in association with pre-existing renal insufficiency.

It is contraindicated in patients with primary biliary cirrhosis, since it may raise the already elevated cholesterol in these cases.

It is contraindicated in patients with a known hypersensitivity to clofibrate.

It is contraindicated in nursing women.

Additional information about Sklero-tabuls

Sklero-tabuls Indication: For Primary Dysbetalipoproteinemia (Type III hyperlipidemia) that does not respond adequately to diet.
Mechanism Of Action: Sklero-tabuls increases the activity of extrahepatic lipoprotein lipase (LL), thereby increasing lipoprotein triglyceride lipolysis. Chylomicrons are degraded, VLDLs are converted to LDLs, and LDLs are converted to HDL. This is accompanied by a slight increase in secretion of lipids into the bile and ultimately the intestine. Sklero-tabuls also inhibits the synthesis and increases the clearance of apolipoprotein B, a carrier molecule for VLDL.

Absorption: Completely but slowly absorbed from the intestine. Between 95% and 99% of an oral dose of clofibrate is excreted in the urine as free and conjugated clofibric acid; thus, the absorption of clofibrate is virtually complete.
Toxicity (Overdose): Oral, mouse: LD₅₀ = 1220 mg/kg; Oral, rabbit: LD₅₀ = 1370 mg/kg; Oral, rat: LD₅₀ = 940 mg/kg. No reported case of overdosage in humans.
Protein Binding: Highly protein-bound (95% to 97%).
Biotransformation: Hepatic and gastrointestinal: rapid de-esterification occurs in the gastrointestinal tract and/or on first-pass metabolism to produce the active form, clofibric acid (chlorophenoxy isobutyric acid [CPIB]).
Half Life: Half-life in normal volunteers averages 18 to 22 hours (range 14 to 35 hours) but can vary by up to 7 hours in the same subject at different times.
