Antacid Actives
SPI Pharma is the global leader in immediate-relief antacid actives. We specialize in aluminum, magnesium, and calcium products, as well as preformulated solutions for the production of antacid suspensions and tablets.
All our facilities meet cGMP requirements for APIs and finished dosage forms (FDFs), also known as semi-finished drugs. When the product is compendial, it meets or exceeds the appropriate USP and/or EP pharmacopoeia specifications. With manufacturing locations in the US and France, SPI Pharma provides security of supply at the highest quality standards through dual sourcing. We work to exceed the expectations for each customer, every time.

As always, our sales and technical teams are ready to assist you with any questions that arise. Your journey to formulation success starts here.
Elemental Impurities
Operating in a highly regulated industry, we understand the importance of minimal elemental impurities for our customers. We perform a thorough risk assessment on all of our products to ensure regulatory compliance. SPI Pharma has invested approximately $1M of testing technology, resources and external testing to ensure our customers the peace of mind that our products are below the threshold and only require annual confirmation testing. Customers can depend on our certification and can alleviate their burden of testing.
Ingredients For Suspensions
We provide a vast selection of viscous pastes, pumpable gels, micronized powders, and preformulated products to save you time, money, and provide excellent mouthfeel.
Aluminum Hydroxide Gels
We provide a wide range of aluminum hydroxide gels varying in assay and viscosity to meet your formulation needs. We have successfully marketed viscous pastes globally for over 50 years.
Magnesium Hydroxide Pastes and Gels
We provide a wide range of magnesium hydroxide gels and pastes varying in assay and viscosity to meet your formulation needs. Selecting the right grade of magnesium gel or paste allows the formulator to make a high-quality antacid at a competitive price.
Magaldrate Gels and Powders
The antacid effectiveness of magaldrate can be used to treat peptic ulcers because it neutralizes gastric acid very quickly while buffering the pH even in presence of proteins and pepsin. We offer gel grades for suspensions and a powder grade for antacid tablets.
CoBlend Suspensions
CoBlend Grades are customize, preformulated, pumpable gels of aluminum hydroxide and magnesium hydroxide combined with sorbitol and preservatives for antacid suspensions.
Micronized Powder Grades
Our micronized aluminum and magnesium hydroxide and aluminum hydroxide magnesium carbonate (AHMC) powders are ideal for antacid suspensions in mini stickpacks and bottles.
Aluminum Phosphate
For your antacid suspensions, aluminum phosphate coats the stomach to provide immediate antacid relief.
Boehmite Gel
For your antacid suspensions, boehmite gel protects the stomach wall by absorbing stomach acid and creating a high viscosity gel.
Ingredients For Tablets
We provide a variety of powders, directly compressible (DC) ingredients or DC preformulated products. Our DC ingredients flow as smooth as milk allowing you to make either chewable tablets with excellent mouthfeel or easy-to-swallow tablets.
Aluminum Hydroxide Powders
A wide range of aluminum powders is available. They vary in density and particle size distribution.
Magnesium Hydroxide Powders
Our line of magnesium hydroxide powders are used in wet granulation and direct compression tableting and suspension applications. A wide range of magnesium powders is available.
DC CoDried Powders
DC CoDried Powders are pre-formulated, directly compressible aluminum hydroxide and magnesium hydroxide for antacid tablets.
Aluminum Hydroxide Magnesium Carbonate Powders
Coprocessed aluminum hydroxide and magnesium carbonate powders for your immediate-relief antacid formulation needs.
Vitasmooth® - DC Calcium Carbonate with Excipients
Vitasmooth is a directly compressible, calcium carbonate preformulated platform for smooth, meltaway antacid or mineral supplement tablets.
CS90 - DC Calcium Carbonate with Starch
CS90 is a directly compressible calcium carbonate with starch for mineral supplement or antacid tablets.
MS90 - DC Magnesium Hydroxide with Starch
MS90 is a directly compressible, magnesium hydroxide with starch for mineral supplement or antacid tablets.
Magaldrate Gels and Powders
The antacid effectiveness of magaldrate can be used to treat peptic ulcers because it neutralizes gastric acid very quickly while buffering the pH even in presence of proteins and pepsin. We offer gel grades for suspensions and a powder grade for antacid tablets.
