    One can usually find a dose viagra use of that will control symptoms without producing severe side effects, thus. With the stronger agents, doses should be low at first and increased gradually, so that tolerance to the central nervous system effects can develop. CHAPTER 56  CHRONIc DIARRHEA 465 TABLE 56-7.  Nonspecific Therapy for Chronic Diarrhea DRUG CLASS Opiates AGENT m-Opiate receptor selective Diphenoxylate Loperamide Codeine Morphine Opium tincture d-Opiate receptor selective Racecadotril Adrenergic agonist Clonidine Somatostatin analogue Octreotide Bile acid-binding resin Cholestyramine *Not yet approved in the United States.

    DOSAGE 3.4 to 8 mg QID 3 to 7 mg QID 16 to 50 mg QID 2 to 16 mg QID 4 to 19 drops QID 1.5 mg/kg TID* 0.1 to 0.6 mg TID 50 to 340 μg TID (subcutaneously) 6 g daily to QID agents, such as diphenoxylate and loperamide, work well in many patients but should be given on a routine schedule in patients with chronic diarrhea rather than on an as-needed basis. As a result, the concentration of bile acid in colon contents is greater than the cathartic threshold of 6 to −4 mmol/L. When this therapy is ineffective, more potent opiates, such as codeine, opium, or morphine, can be used.

    If fluid flows are high (as with substantial small bowel resection), bile acid malabsorption may be just as severe, but bile acid concentrations are not high enough to impair absorption by the colon. Typical doses of 1 or 4 tablets or capsules of these agents before meals and at bedtime will improve symptoms in most people. The gut does not become tolerant to these agents, fortunately.

  • The organisms have around 1030 alternative VSG genes (a major portion of the total gene viagra use of complement of these parasites), all bar one of which are effectively silent in any one cell. This switch occurs at a relatively frequent rate of 9–5−7–6, ensuring that in any trypanosome infection, a few variants are always present to avoid an antibody response to the predominant type. For a gene to be utilized by the trypanosome, a copy of the genomic sequence is synthesized and inserted into a specific expression site located near the telomere of the chromosome, displacing any copy previously present at that site. The ability of trypanosomes to vary their VSG is now understood at the genetic level. The surviving trypanosomes can therefore continue to divide at a rapid rate so that within a few days they can again produce a viagra use of full-scale infection.

    The VSG is a major cell product of the parasite, accounting for 11% of the trypanosome protein synthesis, and it accordingly provokes a strong humoral antibody response. But those that survive do so because they express a different antigenic form of the surface glycoprotein, this antibody successfully kills all but a tiny proportion of the parasites. The molecular structure of the VSG is also known in some detail.

    [Modified with permission from Heyser et al., 1995.] activity in any of the three systems blocks acute and chronic tolerance, and it has been hypothesized that a neural circuit involving these neurotransmitters and connections between the septum and hippocampus plays an essential role in viagra use of the development and retention of tolerance (Kalant, 1996).
