In a randomized, double-blind, placebo-controlled comparison of propafenone (mean dose 13 mg/kg/day n = 102) and sotalol (mean dose 3 mg/kg/day n = 106) in maintaining sinus rhythm after conversion of recurrent symptomatic atrial fibrillation in 300 patients, efficacy was comparable (13). Tolerable adverse effects in those who took propafenone were gastrointestinal discomfort (n — 15), neurological disturbances (n = 9), a metallic taste (n = 4), and generalized weakness (n = 1) nine patients withdrew owing to adverse effects, four with gastrointestinal disorders, three with dizziness, and two with headache there were no prodysrhythmias. 

Irritable bowel syndrome (DBS) is an exceedingly common condition in all societies, characterized by abdominal discomfort or pain in association with altered bowel habit or incomplete stool evacuation, bloating and constipation or diarrhoea, easily go undetected and do not show up with common tests such as blood tests or x-rays. The estimated prevalence in the community is about 10%. Irritable bowel syndrome and its variants, collectively called functional gastrointestinal disorders, constitute 40-50% of all the patients seen by gastroenterologists in Western countries. 

It is important to use these drag with caution in patients with a history of gastrointestinal disorders, renal disease, or liver impairment. The neuromuscular blocking action of die lincosamides poses a danger to patients widi myasthenia gravis (an autoimmune disease manifested by extreme weakness and exhaustion of die muscles). 

The drugp used for gout are contraindicated in patients with known hypersensitivity. Probenecid is contraindicated in patients with blood dyscrasias or uric acid kidney stones and in children younger than 2 years. Sulfinpyrazone is contraindicated in patients with peptic ulcer disease and gastrointestinal inflammation. Colchicine is contraindicated in patients with serious gastrointestinal, renal, hepatic, or cardiac disorders and those with blood dyscrasias. 

These drug are used cautiously in patients with gastrointestinal disorders, renal function impairment and those who are pregnant or lactating. 

These drug are used cautiously in patients with renal or hepatic disease, bladder obstruction, seizure disorders, sick sinus syndrome, gastrointestinal bleeding, and asthma Individuals with a history of ulcer disease may have a recurrence of the bleeding. 

Mastocytosis is a disorder characterized by increased numbers of mast cells in the skin, bone marrow, gastrointestinal tract, Uver, spleen, and lymph nodes [9,10]. The prevalence is unknown the incidence has been roughly estimated to be 3-7 new patients per million per year [9]. Most cases are sporadic with only a limited number (50-100) of cases with mastocytosis reported to pass from generation to generation [11], Mastocytosis presents at any age, although most cases occur during the first 2 years of life (childhood-onset) or after puberty (adult-onset) [9]. Mastocytosis in childhood often is self-limited and involves only the skin, whereas the course in patients with adult-onset disease is normally chronic and includes systemic involvement. 

Tricyclic antidepressants (TCAs) such as amitriptyline and doxepin have been used with some success in the treatment of IBS-related pain (Table 18-5). They modulate pain principally through their effect on neurotransmitter reuptake, especially norepinephrine and serotonin. Their helpfulness in functional gastrointestinal disorders seems independent of mood-altering effects normally associated with these agents. Low-dose TCAs (e.g., amitriptyline, desipramine, or doxepin 10 to 25 mg daily) may help patients with IBS who predominantly experience diarrhea or pain.

This should be initiated once oliguric ATN has been established - and performed on an intermittent basis. Mental status abnormalities, pericarditis, gastrointestinal and hemorrhagic disorders are indications for dialysis other indications are fluid overload and hyperkalemia. Non-oliguric patients in general do not require as many dialyses as do patients with oliguria generally because hyperkalemia is not a problem. 

Lithium not only treats acute episodes of mania and hypomania but was the first psychotropic agent shown to prevent recurrent episodes of illness. Lithium may also be effective in treating and preventing episodes of depression in patients with bipolar disorder. It is least effective for rapid cycling or mixed episodes. Overall, lithium is effective in only 40 to 50% of patients. Furthermore, many patients are unable to tolerate it because of numerous side effects, including gastrointestinal symptoms... 

Nonselective beta blockers (i.e., those with a fairly equal affinity for beta-1 and beta-2 receptors) may produce bronchoconstriction in patients with asthma and similar respiratory disorders. Cardiovascular side effects include excessive depression of heart rate and myocardial contractility as well as orthostatic hypotension. Some of the traditional beta blockers may impair glucose and lipid metabolism, but this effect can be reduced by using one of the newer vasodilating beta blockers such as carvedilol.97 Other side effects include depression, fatigue, gastrointestinal disturbances, and allergic reactions. Beta blockers are generally well tolerated by most patients, however, and the incidence of side effects is relatively low.
