Magnesium hydroxide is widely utilized in the pharmaceutical industry due to its excellent chemical stability and biocompatibility. As a multifunctional pharmaceutical excipient and active ingredient, it plays a significant role in the development of drug formulations and in the treatment and prevention of various diseases, offering innovative solutions for the pharmaceutical sector.

Widespread Use in Antacid Medications
With its mild alkaline properties, magnesium hydroxide is commonly used as an antacid to alleviate symptoms caused by excessive stomach acid, such as heartburn, indigestion, and gastric ulcers. By neutralizing stomach acid, it reduces acidity in the stomach and provides rapid relief from discomfort, making it a frequent component in many over-the-counter medications. Furthermore, magnesium hydroxide has a mild laxative effect, aiding in the relief of constipation by drawing water into the intestines to promote bowel movements. Its gentle action and minimal side effects establish it as a safe and effective ingredient for gastrointestinal medications.
Broad Applications in Combination Drugs
Magnesium hydroxide is also extensively used in combination drugs, often paired with other medicinal components like aluminum hydroxide or calcium carbonate, to enhance efficacy and safety. For instance, the combination of magnesium hydroxide and aluminum hydroxide delivers a more sustained neutralization of stomach acid, reducing the incidence of acid reflux. This makes it suitable for treating chronic gastrointestinal conditions such as gastroesophageal reflux disease, gastric ulcers, and duodenal ulcers. Such composite applications not only boost the therapeutic effects of the drug but also broaden its range of use.
Role in Bone Health as a Magnesium Supplement
In the realm of skeletal health, the use of magnesium hydroxide as a magnesium supplement has garnered significant attention. Magnesium is a crucial element for bone development and the maintenance of bone density. A deficiency in this mineral can lead to an increased risk of osteoporosis and fractures. As a source of magnesium, magnesium hydroxide can effectively supplement the body’s required magnesium, promoting bone health and preventing osteoporosis. It is often combined with nutrients like calcium and vitamin D in bone health supplements to help middle-aged and elderly individuals, as well as those at high risk for osteoporosis, maintain bone strength and reduce fracture risk.
Function as an Excipient in Drug Formulations
Magnesium hydroxide is also widely applied as an excipient in pharmaceutical preparations. Excipients are used to improve the physical properties and processing performance of drugs, such as enhancing tablet hardness and stability. Due to its good chemical stability and biocompatibility, magnesium hydroxide is a commonly used excipient in the pharmaceutical industry. It can effectively improve the compressibility and uniformity of medications, thereby enhancing the quality and production efficiency of tablets. Additionally, magnesium hydroxide can improve the solubility and bioavailability of drugs, facilitating their absorption and action within the body.
Potential in Drug Research and Development
In drug research, magnesium hydroxide exhibits potential anti-inflammatory and antioxidant effects. Studies suggest that it may have promising applications in the management of chronic diseases and the treatment of neurological disorders. Its anti-inflammatory properties could help alleviate inflammation-related conditions, while its antioxidant effects may play a positive role in slowing down the aging process and preventing cardiovascular diseases. These potential pharmacological actions offer new avenues and directions for the development of drugs based on magnesium hydroxide.
Expanding Role in Medical Devices
Moreover, the application of magnesium hydroxide in medical devices is gradually increasing. Its biocompatibility and antibacterial properties have led to its use in medical dressings, dental materials, and implants. It can promote wound healing, prevent infections, and enhance the performance and safety of medical devices. Magnesium hydroxide-based medical materials show broad application prospects in orthopedics, dentistry, and surgery, providing patients with safer and more effective treatment options.
In conclusion, the diverse applications of magnesium hydroxide in the pharmaceutical industry underscore its extensive functionality and importance. From antacids to bone health supplements, and from pharmaceutical excipients to potential drug development, magnesium hydroxide provides a variety of therapeutic and preventive solutions through its unique chemical and biological properties. As drug research deepens and new drug development advances, the prospects for magnesium hydroxide’s application in the pharmaceutical industry will only broaden, offering more innovative solutions for human health management and disease treatment.
