Redesigned bottle adapter promotes dosing safety
The DoseGuard bottle adapter from Comar

Comar, an original member of the safe dosing initiative PROTECT, is launching a new version of its DoseGuard for easier integration into drug packaging. The company will be showcasing the new design at Booth #2871 during EastPack June 14-16, and Comar’s Russ Granato will be speaking in a panel discussion on PROTECT June 16.

DoseGuard is a bottle adapter featuring a valve (shown above) that remains closed until the tip of an oral syringe is inserted. When the syringe is removed, the valve closes to resecure the liquid medicine.

The new low-profile design allows drug manufacturers to use a standard bottle and closure with no special modifications. “They can use what they already have,” reports LouAnn Evans, Director of Strategic Marketing at Comar. “The original design required a modified bottle neck and a modified syringe, and it only worked with select resins. The new product is compatible with a wider range of materials.”

Features of the new DoseGuard include:

  • Compatibility with industry-standard (20-mm) plastic bottles of HDPE, LDPE, PP, PET resins, or glass.

  • Secure connection to the container finish.

  • A valve opening customizable to specific product viscosities.

  • Easily adaptable to an open hole flow restrictor for use with products requiring dosage cups.

  • Single-material, one-piece construction to reduce contamination risks.

Evans reports that manufacturers can now access such product features with “less hassle, less expense.”

In addition, the design could help drug manufacturers comply with FDA’s April 2016 Guidance for Industry, “Safety Considerations for Product Design to Minimize Medication Errors,” she says.

“The latest FDA Guidance for Industry mentions ‘Safety-by-Design,’ which is a concept we strongly believe in,” says Evans. “DoseGuard helps manufacturers fit the FDA recommendations, both figuratively and literally. By increasing its compatibility with industry standard containers and materials, it’s an easier fit in packaging lines. The DoseGuard adapter with its proven effectiveness in passive child safe performance and the accurate dosing of our oral syringe can help significantly to minimize medication errors,” she added.

Caregivers and patients won’t notice any difference in use, says Evans. “They will continue to get the dose accuracy and passive protection they got before,” she says.
