Biological target:
Polyquaternium-1 can inhibit growth of microbial contaminants in multi-dose bottles of topical medications.
In vitro activity:
The aim of this study was to compare the cytotoxic and inflammatory effects of the preservative polyquaternium-1 (PQ-1) containing Travatan (travoprost 0.004%) and Systane Ultra eye drops with benzalkonium chloride (BAK) alone or BAK-preserved Xalatan (0.005% latanoprost) eye drops in HCE-2 human corneal epithelial cell culture. Cell viability, as measured by the MTT assay, declined by up to 50% after exposure to Travatan or Systane Ultra solutions which contain 0.001% PQ-1. BAK at 0.02% rather than at 0.001% concentration evoked total cell death signs on HCE-2 cells. In addition, cell membrane permeability, as measured by LDH release, was elevated by sixfold with Travatan and by a maximum threefold with Systane Ultra. Interestingly, Travatan and Systane Ultra activated NF-κB and elevated the secretion of inflammation markers IL-6 by 3 to eightfold and IL-8 by 1.5 to 3.5 fold, respectively, as analyzed with ELISA.

In vivo activity:
Adult male New Zealand albino rabbits (n=24) were randomly divided into four groups. Phosphate-buffered saline (PBS), travoprost/timolol PQ (polyquaternium-1), travoprost/timolol BAK, or latanoprost/timolol BAK were instilled onto rabbit eyes one drop, 15 times at 5 minute intervals. Travoprost/timolol PQ was better tolerated than travoprost/timolol BAK or latanoprost/timolol BAK. This improved tolerance was evident via clinical observation under slit lamp, IVCM in different layers of the cornea and conjunctiva, conjunctival impression cytology of superficial epithelium aspects, and immunohistochemistry for inflammatory infiltration of CD45+ cells in the cornea and goblet cell distribution. Travoprost/timolol PQ was similar to PBS in regards to in-vivo findings, the Draize test for ocular irritation, and epithelial and limbal aspects as evaluated with IVCM.

Note: There can be variations in solubility for the same chemical from different vendors or different batches from the same vendor. The following factors can affect the solubility of the same chemical: solvent used for crystallization, residual solvent content, polymorphism, salt versus free form, degree of hydration, solvent temperature. Please use the solubility data as a reference only. Warming and sonication will facilitate dissolving. Still have questions? Please contact our Technical Support scientists.
