چکیده

The effects of atropine and metoclopramide on the lower oesophageal sphincter pressure (LOSP) were studied in 12 healthy volunteers using oesophageal pressure transducers. Atropine decreased LOSP significantly at 5 min after i.v. injection (P less than 0.005) and this change was sustained for 60 min. Metoclopramide increased LOSP significantly at 3 min after administration i.v. (P less than 0.05) and this change was sustained for 40 min. Following consecutive administration of the drugs the effects of atropine predominated.

Pharmacological constriction of the lower oesophageal sphincter: a simple method of arresting variceal haemorrhage.

The effect of pharmacological constriction of the lower oesophageal sphincter (LOS) on oesophageal varices was investigated in an experimental study followed by a controlled clinical trial. In the experimental study intravariceal pressure was measured just above the LOS in 11 patients before and after constricting the LOS by intravenous pentagastrin. Intravariceal pressure fell from a mean of 2...

Metoclopramide in gastrooesophageal reflux.

In 30 patients with gastrooesophageal reflux, intravenous metoclopramide (Maxolon) has been shown to increase the gastrooesophageal sphincter pressure. The rise is dose-related until a maximum pressure, proportional to the resting sphincter tone, is reached. The effect is reversed by atropine. Peristaltic waves are increased in pressure by metoclopramide.In 18 patients with gastrooesophageal re...

Measurement of Lower Oesophageal Sphincter Pressure

In 24 control patients the lower oesophageal sphincter responded to graded increments in intra-abdominal pressure by a significant and sustained rise in tone. This response was abolished by atropine and was also absent in nine of 11 patients who had previously undergone truncal vagotomy for duodenal ulcer but not in the remaining two who had recurrent ulceration. In six patients studied after p...

Action of oral metoclopramide on the gastrooesophageal junction in man.

The effect of oral metoclopramide, 10 mg, was studied with intraluminal manometry in 20 patients suffering from symptoms of gastrooesophageal reflux. The drug increased cardiac sphincter pressure and the amplitude of oesophageal peristaltic waves, but gastric motility was stimulated in only half of the patients. The clinical value of these pharmacological effects should be confirmed in therapeu...

Cholinergic blockade inhibits gastro-oesophageal reflux and transient lower oesophageal sphincter relaxation through a central mechanism.

BACKGROUND Atropine, an anticholinergic agent with central and peripheral actions, reduces gastro-oesophageal reflux (GOR) in normal subjects and patients with gastro-oesophageal reflux disease (GORD) by inhibiting the frequency of transient lower oesophageal sphincter relaxation (TLOSR). AIMS To compare the effect of methscopolamine bromide (MSB), a peripherally acting anticholinergic agent,...
