Gaster 10

Gaster 10 is a Japanese over-the-counter medicine brand based on famotidine, an H2-receptor antagonist that reduces the production of stomach acid. The product is positioned for short-term relief of common acid-related gastrointestinal symptoms, including heartburn, acid regurgitation, stomach discomfort, and excessive stomach acidity, subject to the indications, age restrictions, dosage instructions, and warnings approved for the Japanese market. The brand is associated with the Gaster franchise originally developed within the Sankyo pharmaceutical business and subsequently managed through the healthcare businesses of the Daiichi Sankyo group. Its name reflects the broader Gaster family of famotidine products, while the “10” designation is associated with the over-the-counter strength sold in Japan. Unlike prescription medicines, the consumer product is intended for self-medication and is distributed through Japanese pharmacies and drugstores under the country’s regulatory framework for non-prescription drugs. Gaster 10 belongs to the acid-related digestive-health segment rather than to a broad food or wellness category. Its principal value proposition is pharmacological acid control: famotidine blocks histamine H2 receptors in gastric parietal cells and thereby suppresses acid secretion. Consumer information for the product emphasizes reading the package directions, avoiding prolonged self-treatment, and consulting a pharmacist or physician where symptoms persist, recur, are severe, or may indicate another condition. Japanese OTC labeling also includes contraindications and interaction warnings, including circumstances involving other medicines, pregnancy or breastfeeding, kidney or liver conditions, and use by children or older adults, with the exact instructions determined by the approved product labeling. The brand’s significance is primarily domestic. It is recognizable in Japan as an OTC gastrointestinal medicine and is distinct from prescription-strength or overseas products that may use different strengths, formulations, pack sizes, or brand names. Publicly available information supports identifying Gaster 10 as a famotidine-based Japanese OTC brand, but does not provide a sufficiently complete public record for a precise launch year, a detailed advertising chronology, sales figures, named brand executives, or a verified standalone corporate website. Those details are therefore left unspecified.

Gaster 10 is part of the Japanese Gaster line of famotidine medicines. Famotidine is an H2-receptor antagonist used to reduce gastric acid secretion, and the Gaster name became associated with acid-related gastrointestinal treatment in the Sankyo pharmaceutical portfolio. The consumer-facing Gaster 10 product is the over-the-counter expression of that therapeutic franchise in Japan. The brand operates within Japan’s regulated self-medication market. Its role is to provide consumers with access to a non-prescription acid-suppression medicine for specified short-term symptoms, while retaining pharmacist and package-label controls intended to limit inappropriate or prolonged use. The product’s identity is therefore shaped both by the famotidine active ingredient and by Japanese OTC rules governing indications, dosage, age eligibility, warnings, and consultation requirements. Corporate responsibility for the brand follows the evolution of the Sankyo business into the Daiichi Sankyo group and its healthcare operations. Available public information identifies Daiichi Sankyo Healthcare as the relevant operating company for consumer healthcare products, but does not establish a separate legal entity for Gaster 10 itself. The product should consequently be treated as a product brand rather than an independent company. The public record available for this entry is limited. A reliable standalone Wikipedia article or a sufficiently complete archival record was not identified from the supplied material. As a result, the exact introduction date of Gaster 10, changes in formulation or packaging, historic advertising campaigns, sales performance, and detailed corporate milestones cannot be stated with confidence. The durable, verifiable description is that Gaster 10 is a Japan-market OTC famotidine brand used for approved acid-related stomach symptoms.
