Stomach cramps can be relieved quickly by taking belladonna tablets, scopolamine tablets, and magnesium aluminum carbonate. Belladonna tablets are over-the-counter medications that not only inhibit glandular secretion but also release smooth muscle spasm, so they have a relieving effect on stomach cramps and intestinal spasms. Scopolamine tablets are M-cholinergic receptor blockers that relax smooth muscles and therefore have a spasm-relieving effect. The drug is also analgesic, and is a common drug in digestive disorders, and can quickly improve the symptoms of stomach cramps, as well as for cholecystitis, ureteral spasm, and other diseases. Magnesium aluminum carbonate not only can resist stomach acid, but also can protect the gastric mucosa and promote the recovery of the gastric mucosa. Especially for the stomach spasm caused by gastric ulcer, it has good therapeutic effect.
