LIQUID-FILLED CAPSULES
Liquid-filled, two-piece capsules offer several advantages over other solid dosage forms, such as ease of scalability and manufacturing, faster absorption, simpler packaging, and higher product stability. Liquid filling also offers the ability to control R&D compounds, which are expensive and in limited supply. They are also known to accelerate product development because they can be made with fewer excipients than other solid dosage forms, such as tablets.
Drug profiles for which liquid-filled, hard-shell capsules would be suitable include compounds with complex or difficult formulations, as well as low-dose, poorly soluble, and/or highly potent active pharmaceutical ingredients (APIs).

BENEFITS OF TWO-PIECE, LIQUID-FILLED CAPSULES AS A DOSAGE FORM
Water Solubility/Bioavailability ― The bioavailability of compounds with poor water solubility can be significantly enhanced with a liquid formulation in a hard-shell capsule, since your API is already in solution or dispersed suspension.
Low Melting Point ― The manufacturing process of APIs with a low melting point can be greatly simplified by producing them in liquid form used to fill hard-shell capsules.
Low Dose/High Potency ― Studies have shown that the incorporation of potent drugs into liquid-filled capsules during formulation and processing significantly reduces the risk of cross-contamination and airborne powder exposure to operators.
Critical Stability ― Liquid-filled, hard-shell capsules protect the drugs from moisture and produce a stable dosage form.
Sustained Release ― With liquid-filled, hard-shell capsules, drug formulation and polymer composition of the capsule can be customized to accommodate APIs with different properties and desired dissolution profiles.
Simple And Cost Effective Formulation ― Liquid capsules require no binders, lubricants, or plasticizers commonly found in traditional solid-dosage forms and soft gels. Aqueous and non-aqueous liquids to semi-solids can be filled and banded.
Combination Filling ― Unlike softgels, hard-shell gelatin capsules offer the possibility of combination filling. Drugs can be encapsulated in the form of beads, micro tablets, or pellets, in combination with the liquid formulation.
Integrated Tamper Proofing ― Banded and sealed capsules provide a non-permeable barrier.
Abuse-Deterrence ― They offer abuse-deterrent benefits because they make it harder to insufflate, inject, or alter the extended-release properties of potent drugs.
Better Than Softgel Capsules ― Thinner wall construction allows for smaller capsule sizes and more efficient and complete dissolution over soft gels.
Unique Branding Opportunities ― Infinite choices of capsule and banding colors provide a wealth of visually appealing product differentiation options, from clear capsules and clear bands to two-color capsules and contrasting band color ― the combinations are endless.
