What are the applications of gelatin in the pharmaceutical industry?​

1.Capsule Production​
Over 90% of oral solid dosage forms use gelatin capsules. hard capsules, made from gelatin, water, and plasticizers, enclose powders or granules, masking bitter tastes and protecting drugs from moisture.Soft gelatin capsules seal liquids or semi-solids (e.g., fish oil), offering precise dosing and easy absorption. Their biocompatibility and ability to dissolve in the gastrointestinal tract make them ideal for drug delivery.​

2.Drug Delivery Systems​
Gelatin-based microspheres and nanoparticles are engineered for controlled drug release. By adjusting gelatin’s cross-linking, release rates can be tailored—from immediate to sustained over weeks. This is critical for drugs requiring steady blood levels, like painkillers or hormones. Gelatin’s biodegradability ensures these carriers break down safely in the body.​

3.Wound Care​
Gelatin sponges and hydrogels are used in surgeries to control bleeding. They absorb 40–50 times their weight in blood, forming a gel that activates clotting factors. As a scaffold, gelatin supports cell migration and tissue regeneration, accelerating wound healing in burns and ulcers. Its biocompatibility minimizes immune reactions, a key advantage over synthetic alternatives.​
