Colestipol (trade names Colestid, Cholestabyl) is a bile acid sequestrant used to lower blood cholesterol, specifically low-density lipoprotein (LDL). It is also used to reduce stool volume and frequency, and in the treatment of chronic diarrhea.Like cholestyramine, colestipol works in the gut by trapping bile acids and preventing them from being reabsorbed. This leads to decreased enterohepatic recirculation of bile acids, increased synthesis of new bile acids by the liver from cholesterol, decreased liver cholesterol, increased LDL receptor expression, and decreasing LDL in blood. Side effects
The following notable side effects may occur:
gastrointestinal tract disturbances, especially (mild, occasionally severe) constipation
sometimes increase in VLDL and triglyceride synthesis

Interactions
Colestipol can bind to a number of drugs and nutrients in the gut and inhibit or delay their absorption. Such substances include:
thiazide diuretics, furosemide
gemfibrozil
benzylpenicillin, tetracycline
digoxin
lipid-soluble vitamins (A, D, E, K)

Contraindications
Colestipol is contraindicated in hypertriglyceridemia (high level of triglycerides in the blood). Chemistry
Colestipol is a copolymer of diethylenetriamine (DETA) —or tetraethylenepentamine according to some sources— and epichlorohydrin. The structure drawing (top right) shows the DETA moieties in blue and the epichlorohydrin moieties in red. == Notes and references ==
It has also been reported from sharing of swimsuits, underwear, or bath towels, and from non-sexual touching during routine care such as diapering. Genital warts in children are less likely to be caused by HPV subtypes 6 and 11 than adults, and more likely to be caused by HPV types that cause warts elsewhere on the body ("cutaneous types"). Surveys of pediatricians who are child abuse specialists suggest that in children younger than 4 years old, there is no consensus on whether the appearance of new anal or genital warts, by itself, can be considered an indicator of sexual abuse. Diagnosis
The diagnosis of genital warts is most often made visually, but may require confirmation by biopsy in some cases. Smaller warts may occasionally be confused with molluscum contagiosum. Genital warts, histopathologically, characteristically rise above the skin surface due to enlargement of the dermal papillae, have parakeratosis and the characteristic nuclear changes typical of HPV infections (nuclear enlargement with perinuclear clearing). DNA tests are available for diagnosis of high-risk HPV infections. Because genital warts are caused by low-risk HPV types, DNA tests cannot be used for diagnosis of genital warts or other low-risk HPV infections.Some practitioners use an acetic acid solution to identify smaller warts ("subclinical lesions"), but this practice is controversial. Because a diagnosis made with acetic acid will not meaningfully affect the course of the disease, and cannot be verified by a more specific test, a 2007 UK guideline advises against its use.
