Soft gels or soft gelatin capsules provide an ideal drug delivery vehicle for controlling absorption and enhancing bioavailability of both insoluble and lipid-soluble compounds. In addition, soft gels offer many other key advantages and therapeutic benefits:
Ease of Swallowing
Uniformity and precision dosage
Dosage and formulation are tamper-resistant (a punctured or tampered softgels will leak or become discoloured)
Protection against counterfeit
Protection from light for photosensitive formulations
Masking of objectionable odors and tastes
Protects drug from oxidation and degradation
Size, shape and colour customization
Imprintability of capsules
Softgel benefits of Biological and marketing advantage:
Better protection of active ingredients—hermetically sealed dosage form protects drug from oxidation and degradation.
Improved absorption and bioavailability— any formulations in softgel can enhance bioavailability or produce a quicker onset of action.
Marketplace differentiation—a nearly endless array of shapes, sizes and shell colors helps your product stand out from branded or generic competitors.
Consumer preference—results of studies done through the years show that consumers expressed their preference for softgels in terms of ease of swallowing, perceived speed of delivery, lack of unpleasant odor or taste, and modern appearance.
Tamper evidence—a punctured or otherwise tampered softgel will leak or become discolored, indicating a potential problem.
