INTRODUCTION
Ferric maltol is an oral iron complex composed of ferric iron (Fe³⁺) chelated with maltol, designed to improve iron absorption while reducing common gastrointestinal side effects associated with traditional iron salts. It is primarily used in the management of iron deficiency with better tolerability.
MANUFACTURE
Ferric maltol is manufactured by complexing ferric iron salts with maltol under controlled aqueous conditions, followed by purification and drying to obtain a stable iron–maltol complex. The process ensures consistent chelation, optimal iron content, and high product purity suitable for pharmaceutical use.

APPLICATIONS
Primarily used for the management of iron deficiency. Its key applications include:
| Treatment of iron deficiency anemia (IDA): |
| Used in adults who cannot tolerate or do not respond well to conventional oral iron salts (such as ferrous sulfate). |
| Inflammatory bowel disease (IBD) patients: |
| Particularly beneficial in patients with Crohn’s disease or ulcerative colitis, as it has better gastrointestinal tolerability and minimal mucosal irritation. |
| Chronic iron deficiency conditions: |
| Suitable for long-term iron supplementation in conditions requiring sustained iron replacement, including chronic blood loss or malabsorption. |
| Patients requiring improved compliance: |
| Due to fewer gastrointestinal side effects (nausea, constipation, abdominal pain), ferric maltol improves adherence compared to traditional iron therapies. |
| Pharmaceutical formulations: |
| Used in oral solid dosage forms such as capsules and tablets for prescription iron therapy. |

Magnesium trisilicate is an inorganic compound commonly used in pharmaceutical and gastrointestinal (GI) preparations due to its dual action. It is usually produced as a white, odorless, fine powder. It helps bind toxins or irritants in the gastrointestinal tract and occasionally used in formulations for its stabilizing properties.
Choline salicylate is a salicylate salt formed from choline and salicylic acid. It is a non-steroidal anti-inflammatory agent (NSAID-type compound) mainly used for its analgesic, anti-inflammatory, and mild antiseptic properties. Unlike acetylated salicylates, it is less irritating to the gastric mucosa and is commonly used in topical oral preparations such as gels and mouth paints.
TensyraTM N-10 (Octoxinol 10; tert-octyl phenyl ethoxylate) is a non-ionic surfactant known for its excellent solubilizing and membrane-permeabilizing properties. It features a hydrophilic polyethylene oxide chain paired with a lipophilic aromatic hydrocarbon group.It readily breaks down biological membranes to lyse cells, solubilize proteins, and permeabilize cell membranes for assays.
Teprenone (Geranylgeranylacetone, GGA) is a mixture of the all-trans and mono-cis isomers of 6,10,14,18-tetramethyl-5,9,13,17-nonadecatetraen-2-one (in a weight ratio of 3:2). It is an acyclic isoprenoid compound with a structure like retinoids and is widely used for the treatment of gastrointestinal ulcers.
Ciclopirox Olamine (CPO) is the N-oxide of a 2 -hydroxy pyridine derivative that carries antifungal, antibacterial, and anti-inflammatory properties. It is composed of 6-cyclohexyl-1-hydroxy-4-methyl-2(1H)-pyridone combined with 2 aminoethanol (olamine) in a 1:1 ratio.
N,N-Dimethylglycine sodium salt (DMG Na) is the sodium salt form of N,N-dimethylglycine, a tertiary amino acid derivative is white to off white crystalline solid, freely soluble in water.
Blown Castor Oil (15-17 Poise) is a modified grade of Castor oil. The “15-17 Poise” specification refers to its viscosity range, indicating a medium-viscosity blown oil suitable for industrial applications requiring improved body, tackiness, and elasticity compared to regular castor oil.
Dimethylaminoethanol (DMAE) is a is a tertiary amine that is ethanolamine having two N-methyl substituents. It is clear & colourless to pale yellow liquid with ammoniacal odor. DMAE is stable at room temperature and is completely miscible with water as well as organic solvents such as alcohols and ethers. It decomposes at high temperatures. It is a versatile chemical intermediate primarily used as a curing agent for polyurethane foams and epoxy resins.
1,4,7-Trimethyl-1,4,7-triazonane (Me₃TACN) is a valuable macrocyclic tridentate ligand derived from 1,4,7-triazacyclononane. In Me₃TACN, each nitrogen atom is substituted with a methyl group, which significantly modifies its steric and electronic properties. Me₃TACN is widely used as a ligand in coordination chemistry due to its ability to form stable complexes with transition metals such as Cu, Ni, Fe, Mn, and Zn.
