In this study, the effects of two antimalarials-amodiaquine hydrochloride and artemisinin were investigated in ulcerated albino rats of Wistar strain. Rats were treated with amodiaquine (30 mg kg(-1)) and Artemisinin (2.86 mg kg(-1)) for 24 h after formation of ulcers induced by indomethacin. Treatments with Amodiaquine Hydrochloride led to significantly increased gastric lesions while artemisinin led to significantly decreased gastric lesions. Also, amodiaquine hydrochloride seemed to… Expand
Effects of artemisinin, with or without lumefantrine and amodiaquine on gastric ulcer healing in rat
TLDR
It is revealed that although artesunate may be beneficial in gastric ulcer healing, its combination with either lumefantrine or amodiaquine may delay healing of gastric mucosal injury. Expand
Effect of Sulfadoxine-Pyrimethamine and Artesunate on Gastric Acid Secretion and Parietal Cell Mass in Rats
TLDR
Sulfadoxine-pyrimethamine and artesunate inhibit gastric acid secretion, inhibited histamine (H2) and muscarinic (M3) receptors, and reduced parietal cell mass. Expand
Effects of quinine on gastric ulcer healing in Wistar rats
TLDR
QT delayed ulcer healing by prolonging the inflammatory phase of healing, increasing oxidative stress, reducing antioxidant activity and gastric mucus secretion. Expand
Antimalarial combination therapies increase gastric ulcers through an imbalance of basic antioxidative-oxidative enzymes in male Wistar rats
TLDR
Investigation of the effects of Artesunate-Amodiaquine and Artemether-Lumefantrine on ulcer induction demonstrated a need to revisit information on the pharmacodynamics of major circulating antimalarial agents in developing countries. Expand

TLDR
Chloroquine and amodiaquine increased gastric acid secretion in rats and stimulated histamine (H2) and muscarinic (M3) receptors, and enhanced parietal cell mass and GMP in rats. Expand

Preliminary studies on effect of chloroquine phosphate on gastric acid secretion in rats.
TLDR
It is concluded that chloroquine is a weak stimulant of gastric acid secretion rats and inhibits histamine-stimulated acid secretion probably by occupying histamine H (2) receptors in rats. Expand
Effect of a novel xanthine derivative on experimental ulcers in rats.
TLDR
The data suggest that the 3-ethylxanthine A90 6119 possesses pronounced anti-ulcer activity and that its repeated administration might not aggravate ulcer formation and might reduce the incidence of recurrence. Expand
Lead exposure increases oxidative stress in the gastric mucosa of HCl/ethanol-exposed rats.
TLDR
Lead increases the formation of gastric ulcers by interfering with the oxidative metabolism in the stomach by affecting catalase and superoxide dismutase activities and the amount of nitrite in gastric mucosal samples. Expand
Effects of diets containing seeds of Garcinia kola (Heckel) on gastric acidity and experimental ulceration in rats
TLDR
It was observed that G. kola produced a dose‐dependent inhibition of gastric acid secretion and indomethacin‐induced ulceration, suggesting that this might be due to its acid‐lowering effect and increased mucus production among other factors yet to be determined. Expand
Investigations of indomethacin-induced gastric ulcer in rats.
TLDR
Results suggest that an overproduction of leukotrienes and other lipoxygenase products, following cyclo oxygengenase blockade induced by NSAIDs, may play a role in the development of gastric mucosal damage. Expand
Effects of indomethacin, piroxicam and selected prostanoids on gastric acid secretion by the rat isolated gastric mucosa
TLDR
The potency of the thromboxane mimetic U‐46619 as an inhibitor of histamine‐induced acid secretion was markedly reduced in the presence of indomethacin, suggesting that U‐46519 may release endogenous antisecretory prostanoids. Expand
