Randomized Controlled Trial Clinical TrialTranexamic acid in gastric and duodenal bleeding.
In this prospective, randomized, double-blind study the effect of the antifibrinolytic drug tranexamic acid was compared with that of placebo in 154 patients bleeding from verified benign lesions in the stomach and/or duodenum. Three out of 72 patients receiving tranexamic acid underwent emergency surgery, in contrast to 15 out of 82 in the placebo group (p = 0.010). ⋯ Side effects were seen in six patients, of which an uncomplicated deep venous thrombosis was the most severe. It was concluded that tranexamic acid reduces the blood transfusion requirement and the need for emergency surgery in patients bleeding from a benign gastric or duodenal lesion.

ReviewTranexamic acid in acute upper gastrointestinal bleeding.
The effect of the antifibrinolytic substance, tranexamic acid, has been studied in 5 double-blind, randomized, placebo-controlled trials in patients with acute upper gastrointestinal bleeding. The results of these trials have varied with regard to blood transfusion requirements and the frequency of operations. All of the studies have shown lower mortality in patients treated with tranexamic acid. Thus tranexamic acid would seem to be indicated in acute upper gastrointestinal bleeding.

Non-ulcer dyspepsia (NUD) is a poorly defined heterogenous condition less well suited for the conventional randomized and placebo controlled parallel type trials. We have designed a multi cross-over model (MCO-model) with the facility of providing information about drug responses in individual patients. A pilot study suggested that the model may identify individual cimetidine responders among patients with dyspepsia. Preliminary findings from an ongoing study in patients with NUD supports the existence of a subgroup of cimetidine responders characterized by gastroesophageal reflux symptoms and possibly an increased basal acid secretion.
