MPS TipGuard™ Caps – Protect Critical Space During Ophthalmic Preparation

The MPS TipGuard™ is designed to protect the most critical component space during compounding preparations – the dropper tip. The TipGuard™ caps come pre-assembled with the tip inside the cap. This design completely removes the need for a compounder to ever touch the tip during assembly of dropper bottles during their preparation.

Color Caps by Therapeutic Class

Select the right cap color for your drugs as defined by the American Academy of Ophthalmology. AAO endorses the use of a color-coding system for caps and labeling of topical ocular medications.

Packaging configured by and for compounders

Up to three layers of packaging on specific lines allow compounders to reduce handling and wipe down steps.

TipGuard™ caps are neatly organized in an easy-to-use tray with clear packaging for effortless visual inspection.

Sterility and Endotoxin

Each lot is released sterile and tested for endotoxin through one of our qualified third-party testing labs

All lots will be accompanied with a detailed Certificate of Analysis showing the measured cleanliness of the product.

Measured Cleanliness - USP <788> Particulate Tested

Each lot is measured for particulates via a USP <788> methodology through one of our qualified third-party testing labs as follows:

All lots will be accompanied with a detailed Certificate of Analysis showing the measured cleanliness of the product.

Controlled Tip Dosage

• Each dropper contains a specially engineered dropper tip for an accurate and repeatable dosage
• Tip will only dispense a drop when the bottle is squeezed
• Once the bottle is squeezed the tip will form a consistent drop size

Robust Documentation for your Quality Records

Every Lot Release is accompanied by a detailed Certificate of Analysis which includes certifications and measurements of:

  • Sterility
  • Endotoxin
  • USP <788> level particulates

For your initial qualification activity, we’ve assembled a detailed product information packet. This packet includes:

  • Materials information
  • Sterilization information
  • Dimensional information

If you need something above and beyond what are documentation has to offer, we can work with you to get it.

    Supply Agreement Options

    Having steady and reliable ophthalmic dropper supply is critical to your pharmacy operations. Being out of bottles can lead to pharmacy operations coming to a halt.

    MPS can work with your team to set-up an on-going supply agreement in a number of way including scheduled deliveries or dedicated supply. Contact MPS today for options

      Frequently Asked Questions

      What final release testing is performed for these bottle products?
      Test Method Component
      Sterility Direct Transfer Method Embedded Spore Strip accredited to the ISO 17025 Bottle, Tip, Cap
      Endotoxin/LAL ISO 17025 – (USP), General Chapter <85>, (USP), General Chapter <161>, Medical Devices Bottle, Tip, Cap
      USP <788> Test Method 1 – Particulates Test Method Acceptance Criteria: Based on the methodology of USP <788> Bottle, Tip (Testing limited to fluid contact surfaces)

      All testing is performed by qualified third party testing labs contracted with MPS Pharma. The final measurements are all reported on our current Certificate of Analysis.

      Why do you measure particulates to USP <788>?
      Our bottles are most used for topical ophthalmic preparations in the form of eye drops. This is a form of extraocular application of medication to the eyes. Specific chapters in USP guidelines state as follows:

      USP <771> Ophthalmic Products – Quality Tests:

      “Two general categories apply for product administration to the tissues in the eye. Intraocular administration includes all ophthalmic products that cross (penetrate) boundary tissue, such as the cornea and sclera. For subvisible content, USP guidance is followed. Products for intraocular use must comply with Particulate Matter in Ophthalmic Solutions <789>. Product for extraocular use must comply with Particulate Matter in Injections <788>.”

      Both USP <788> and <789> are applicable to finished drug products; containers are not considered finished drug product. The testing MPS Pharma has performed on the bottles is based on the methodology of USP <788>, with particulate measurements reported for 10 um and 25 um sizes against limits reported on a per container basis.

      Can I see a sample Certificate of Analysis that comes with this product?
      See the attached PDF for a sample Certificate of Analysis
      I have a special requirement (new pack size, special drop size, etc). Can you help?
      We can and are willing to provide our customers options that aren’t available in our existing catalog. We are always open to adding them. Much of the depth in our catalog is specifically due to fulfilling requests just like this. Contact us with your requirements to start collaborating today.
      Are the parts interchangeable? How does the numbering system work on these parts?
      The interchangeable/mating parts in our catalog are designated with a special numbering system. These can be identified with the pre-fix.

      All items with a UA8-425 pre-fix are compatible with each other.

      All items with a UA15-415 pre-fix are compatible with each other.

      UA8-425 & UA15-415 items are not compatible with each other.

      If I open the pouch, will the bottle contents still be sterile?
      Once the pouch has been opened, then by the definition the parts cannot be considered sterile, unless the pouch is opened in a controlled sterile environment.
      What is the drop size for these bottles?
      Drop size is dependent on several factors including the product being dispensed and the technique in which it is dispensed. The best advice for customers is to test the dropper tip with the compounded product to determine its suitability in its application.

      A general water reference point can be provided to our customers as a starting guideline:

      Size(s) Drop Size
      3 mL 42 ul +/- 5 uL
      7, 10, 15, 30 mL 40 ul +/- 5 uL
      What are the bottles made of? Can more information be shared?
      The bottle and tip itself are composed of low-density polyethylene resin (LDPE). These are the fluid contact surfaces. The cap itself is composed of polypropylene (PP) and can be considered a non-fluid contact surface.

      A more detailed material profile is available to share with customers who complete a non-disclosure agreement.

      Are dimensional drawings of the bottle available?
      Detailed dimensional drawings are available to customers.
      Do you carry bottles that offer UV protection? Is there data available to share?
      MPS carries a series of white bottles and tips that can be used in conjunction with colored caps to create a container closure system that protects a solution from UV light.

      Specific testing standards surrounding UV protection of solutions are always performed using the container closure system itself plus the drug contents. MPS does not provide drug with the bottle, therefore no meaningful data can be provided that our end user pharmacies may leverage for their own purposes.

      We can anecdotally report however that our customers do routinely use specific products of ours for light protected solutions. Those same customers do report the bottle, in combination with their drug product, pass the UV protection requirement as defined in the existing testing standards.

      Please reach out to us to find out which items would work best in supporting a successful passage of these tests.

      Can I get a specification sheet of this item for my records?
      See the attached document for the specification sheet
      Our pharmacy follows USP <797> and it requires we use depyrogenated materials. Are your products depyrogenated? Do you have a Certificate of Analysis (C of A) stating such?
      All MPS lots are tested for endotoxins (pyrogens) and will meet the materials requirements as defined in USP <797>. A detailed explanation of this can be found in this PDF link. All MPS C of As include measurements for these endotoxins.
