Application Engineered Capsules

Polymer chemistry expertise combined with capsule design and manufacturing expertise has resulted in a range of functional capsules to meet your formulation and drug delivery needs. 

Coni-Snap® Hard Gelatin Capsules – The reliable and outstanding performance of Coni-Snap® hard gelatin capsules (HGCs) has made them a product of choice for biopharmaceutical companies since their unique locking closure was introduced. Designed and engineered to perform, they are a reliable and widely used capsule.

Vcaps® Plus Capsules – The new standard in HPMC capsules in both Sigma Series quality and performance, providing immediate release in-vivo performance bioequivalent to gelatin, and superior capsule disintegration without the risk of cross-linking.  

Vcaps® Enteric Capsules – Enteric protection and/ or delayed release option without the complexity of coatings.

Capsugel® Zephyr® Dry-Powder Inhalation (DPI) Capsules – Custom inner surface properties, customized moisture levels an and more stringent microbial limits all designed to optimize inhalant end-product performance.

Coni-Snap® Sprinkle Capsules – Designed to be easily opened by patients and caregivers, these capsules are ideal for pediatric and geriatric populations. Available in gelatin and HPMC. 

DRcaps™ Capsules – Designed to protect acid-sensitive ingredients - originally for the nutritional market. A gamma scintigraphy study showed an average of 52 minutes to first opening. 

Press-Fit® and Xpress-Fit® Gelcaps – Proprietary gelcap technology lets you enrobe caplets with high-gloss gelatin covers to create a unique brand for your product.


Specialized Capsules for Clinical Studies and Research & Development

Moving a compound from the lab all the way through to the pharmacy presents numerous challenges. Capsugel has developed capsules that can streamline operations at key points in the clinical trial process. 

DBcaps® Capsules – A unique locking mechanism provides a cost-effective patient solution for double-blind clinical trials in HPMC or gelatin. 

Colorista® Capsules – An optimized tool for formulation development enabling compatibility studies before deciding on the final color for the commercial drug products. Available in gelatin and HPMC.

PCcaps® Capsules – Very small capsules designed specifically for oral delivery in pre-clinical studies. 

Encapsulated Products

Capsugel uses liquid-filled hard capsule (LFHC) and soft gel technology as innovative formulation solutions for handling low dose / highly potent APIs, addressing solubility challenges using lipid-based approaches, and delivering combination products.

Liquid Filled Hard Capsules (LFHC) – Liquid and semi-solid filled and sealed capsules available in gelatin, non-GMO Project verified vegetarian, and acid-resistant vegetarian polymers.

Soft Gelatin Capsules – Softgel option for semi-solid and liquid applications with specialized capabilities in low dose, hormones and other challenging applications. 

Capsule-in-Capsule – innovative capsule-in-capsule technology utilizes LFHC for an innovative approach for combination products and multi-phase release.
