The bioavailability of atenolol may be decreased by impaired GI absorption induced by ampicillin. Possibly inhibition of oxidative metabolism of -blockers and additive pharmacologic effects. Reduced hepatic lidocaine metabolism and possibly a minor component of diminished hepatic blood flow. Oxidative metabolism of certain -blockers may be inhibited by quinidine. Possibly due to increased hepatic metabolism from enzyme induction by rifamycins. Certain -blockers may interfere with cyclosporine metabolism. Carvedilol may increase digoxin bioavailability. Possible additive depression of myocardial conduction and decreased renal tubular digoxin secretion. Inhibition of CYP2D6mediated -blocker metabolism. Additive myocardial depressant effects. Barbiturates enhance enzyme induction and hepatic first-pass extraction that may reduce oral bioavailability of certain -blockers. Cimetidine may reduce hepatic first-pass extraction, decrease liver blood flow, and inhibit hepatic metabolism of propranolol.

No two studies employed the same outcome measures and consequently a quantitative synthesis was not possible. Results from a single trial in this review suggest that anal biofeedback is superior to vaginal, and that electrical stimulation might enhance the results of exer222 cises [222]. However, the trial focused on the use of electrical stimulation as an adjunct to biofeedback and compared two very different types of interventions vaginal pelvic floor manometric pressure biofeedback and home exercise with anal EMG biofeedback and home exercises in combination with anal electrical stimulation ; and did not just single out the effects of electrical stimulation or biofeedback. Moreover, it is difficult to know how much of this improvement is a consequence of the natural history of faecal incontinence following childbirth as a no-treatment group was not included. It appears also that training to enhance rectal discrimination of sensation may be helpful in reducing faecal 216 incontinence, at least in the short term [216]. It may be that adding this technique to the more commonly-available pelvic floor muscle training would enhance results, but this cannot be a strong recommendation in view of the small numbers and lack of follow-up data. The evidence suggests that biofeedback and exercises have an effect in clinical practice and a role in the treatment of patients with faecal incontinence, with only one treatment study reporting no benefit at all and the majority improving at least 50% of patients at least to some degree. However, it cannot be claimed that biofeedback is the effective element in what is inevitably a complex package of care, including assessment and the opportunity to discuss these taboo symptoms, time and attention with an enthusiastic therapist, patient information and teaching, and often supplementary advice on diet, medication and lifestyle. It is not known whether these elements, exercises alone, or the biofeedback itself, are the determining factor in symptom improvement. Well-designed controlled trials are needed to clarify these issues.

The enzyme most clearly associated with the ODMC pathway was CYP2C9 although the incomplete inhibition with sulfaphenazole suggests the involvement of other P450s in this pathway. From the P450 expression systems and the correlation analysis data candidates include CYP2D6 and possibly CYP1A2 and CYP2E. The three strands of evidence correlation, inhibition, and expression ; were not always entirely consistent but were generally supportive of one another. For the pathways that could be investigated in this in vitro study CYP2D6, CYP2C9, and CYP1A2 were clearly the most important P450 enzymes. Thus, the enzymology of carvedilol metabolism is complex and the significance of any given P450 in the disposition of either enantiomer of carvedilol will depend on the balance of the P450 enzymes in an individual. Non-oxidative pathways may also be important determinants of carvedilol disposition since direct conjugation has also been described 2 ; . The significance of CYP2D6 in the disposition of carvedilol has been determined in vivo using poor and extensive metabolizers 19 ; . The partial metabolic clearance of carvedilol to the 4OHC and 5OHC metabolites showed a significant reduction in the poor metabolizers; however, these metabolites were still formed in these individuals. The relatively modest difference in the plasma half life of S ; -carvedilol 1.4-fold ; and R ; -carvedilol 1.8-fold ; between the two groups was!
