Gastric Acid

Publication Title: 
Homeopathy: The Journal of the Faculty of Homeopathy

BACKGROUND: Homeopathy is based on the principle of similitude (similia similibus curentur) using medicines that cause effects similar to the symptoms of disease in order to stimulate the reaction of the organism. Such vital, homeostatic or paradoxical reaction of the organism is closely related to rebound effect of drugs. METHOD: Review of the literature concerning the rebound effects of drugs used to suppress gastric acidity, particularly proton pump inhibitors (PPIs). RESULTS: The mechanism of action of these effects is discussed.

In continuation of our drug discovery program on Indian medicinal plants, the gastro protective mechanism of chebulinic acid isolated from Terminalia chebula fruit was investigated. Chebulinic acid was evaluated against cold restraint (CRU), aspirin (AS), alcohol (AL) and pyloric ligation (PL) induced gastric ulcer models in rats. Potential anti-ulcer activity of chebulinic acid was observed against CRU (62.9%), AS (55.3%), AL (80.67%) and PL (66.63%) induced ulcer models.

The ability of hypnosis to both stimulate and inhibit gastric acid secretion in highly hypnotizable healthy volunteers was examined in two studies. In the first, after basal acid secretion was measured, subjects were hypnotized and instructed to imagine all aspects of eating a series of delicious meals. Acid output rose from a basal mean of 3.60 +/- 0.48 to a mean of 6.80 +/- 0.02 mmol H+/h with hypnosis, an increase of 89% (p = 0.0007).

Pepticare, a herbomineral formulation of the Ayurveda medicine consisting of the herbal drugs: Glycyrrhiza glabra, Emblica officinalis and Tinospora cordifolia, was tested for its anti-ulcer and anti-oxidant activity in rats. Effects of various doses (125, 250, 500 and 1000mg/kg, p.o.) of Pepticare were studied on gastric secretion and gastric ulcers in pylorus-ligation and on ethanol-induced gastric mucosal injury in rats.

Solanum nigrum, an herbal plant which is recommended in ayurveda for the management of gastric ulcers. Therefore, the purpose of the study was to investigate the antiulcer effect of Solanum nigrum fruits extract (SNE) on cold restraint stress (CRU), indomethacin (IND), pyloric ligation (PL) and ethanol (EtOH) induced gastric ulcer models and ulcer healing activity on acetic acid induced ulcer model in rats.

ETHNOPHARMACOLOGICAL RELEVANCE: Cedrus deodara (Roxb.) Loud. is used in Ayurvedic medicine to treat peptic ulcer. AIM OF THE STUDY: To evaluate the gastric antisecretory and antiulcer activity of Cedrus deodara. MATERIALS AND METHODS: The volatile oil extracted by steam distillation of Cedrus deodara wood was examined for its gastric antisecretory and antiulcer effect in the pylorus-ligated rat model and ethanol induced gastric lesions in rats.

ETHNOPHARMACOLOGICAL RELEVANCE: Baccharis trimera (Less.) DC. (Asteraceae) is a species native to South America used in Brazilian folk medicine to treat gastrointestinal and liver diseases, kidney disorders and diabetes. Previous studies from this laboratory confirmed the antacid and antiulcer activities of the plant aqueous extract (AE) in rat and mouse models. AIM OF THE STUDY: To investigate the mechanisms involved in the antacid action of AE and isolated compounds from Baccharis trimera.

The effect of intermittent dosage with omeprazole on basal and pentagastrin stimulated gastric acid secretion and fasting plasma gastrin was assessed in eight duodenal ulcer subjects who were in remission. Omeprazole (20 mg daily) was given for a three day 'weekend' each week for two months. Twenty four hours after the first and eighth weekend, basal and peak acid output were still markedly suppressed (greater than 50%) compared with pretreatment.

OBJECTIVE: To study the effects of the somatostatin analog octreotide on gastric mucosal function and histology during short-term (3 months) preoperative treatment in patients with acromegaly. DESIGN: Open design clinical study. METHODS: 10 patients were studied before treatment with octreotide (pre-tx), on day 1 of 300 microg octreotide/day (d300), after 1 week on 300 (w300), 600 (w600) or 1500 (wl500) microg octreotide/day, and after an additional 2.5 months on 1500 microg octreotide/day (M3).
