Glucosamine hydrochloride capsules are effective in the treatment and prevention of arthritis in the knee, shoulder, hip, wrist, neck, and spine and ankle joints, reducing or eliminating the pain caused by arthritis. Arthritis is mainly caused by a lack of proteoglycans. Glucosamine hydrochloride is an amino monosaccharide that enhances the repair ability of cartilage cells and promotes cartilage repair, thereby delaying bone and joint pain, improving joint movement, and relieving pain. It is important to note that the drug should be taken before or after meals, but it should be used with caution in patients with gastrointestinal diseases such as gastritis, gastric ulcer, or severe liver and kidney insufficiency. Use with caution in pregnant and lactating women. If the symptoms are not relieved after one course of medication, you should go to the hospital promptly.
