Eye drop bottle

Ophthalmic solutions or eye drops are probably one of the fastest growing pharmaceutical products. You buy them to treat a variety of viral and bacterial eye infections, irritations, allergies, and dry eyes. They are also used to treat eye injuries, before eye exams, and before and after eye surgery. However, consumer complaints indicate that the quality as well as the design of the eye drop bottle used and even the ear drops may leave many flaws. In fact, the bottle cap not closing well has created health and safety issues as well as economy of use, and as a result, pharmaceutical companies demand higher quality in the manufacture of eye drop bottles.

These small bottles are usually produced using an injection blow molding machine.

The bottle closure system, including the seal, outer cap and solution dispensing nozzle, play a very important role in maintaining the sterility of the solution inside and preventing contamination during use. So a good quality eye drop bottle should not only ensure these things, but also regulate the volume of the eye drops to prevent them from being wasted and also ensure ease of use. It is very important to ensure that the eye drop bottle meets all these requirements.

Eye drop bottle

Most eye drop bottles include a cap that covers the dispensing unit, with a sealing ring attached at the bottom. When you open the cap for the first time, you automatically break the seal, thereby removing the ring from the cap. Sometimes this ring may break and fall by itself. But most of the time, you have to remove the cap and then the ring, screw the cap back on, and apply enough torque that the spike under the cap pierces the tip of the dropper, creating a small hole through which the liquid drips. going out. .
Consumer complaints indicate that the biggest problem with eye drop bottles is the poor quality of the perforation mechanism. Sometimes the barb is not sharp or long enough to pierce the nozzle, or there is some misalignment of the cap tube that prevents the opening of the barb, thereby making access to the drug impossible. What makes matters worse is the refusal of chemists to replace such bottles because the seal is broken by the consumer. What they fail to understand is that such eye drop bottles are defective and must be replaced and the defect reported to the drug company and the regulator.

Even where the spike works and creates an aperture in the nozzle, consumers say they often have to use considerable force to turn the cap and only succeed after several attempts. Considering that many elderly people use several of these solutions after cataract surgery and may not have very strong and dexterous fingers, this is a very serious defect and should be corrected. In fact, the closing system of the eye drop bottle should be simplified to ensure that the seal is broken and the nozzle is opened in one easy step.
Consumers also report changes in the way the medicine comes out of the eye drop bottle. While in some bottles, the drops come out quickly and waste the medicine, in others, it is so slow that you blink and close your eyes until the drop falls. Due to the high price of these drugs, the drug control authority should really ensure that the eye drop bottle, nozzle design and opening size ensure proper control over the volume as well as the speed of dispensing.
In fact, several studies around the world have focused on the need to reduce the volume of drug wastage to reduce its cost, especially for those on long-term medication, such as glaucoma patients. For example, a study on the topic published in the Journal of Advanced Pharmaceutical Technology and Research in 2011 (Shiva Kumar et al.) concluded that “droplet sizes greater than 25 microliters (μL) result in drug wastage and cost Pharmacokinetic studies have shown that the maximum tear film concentration can be achieved with a 20 μL drop. While increasing the drop size does not increase efficacy beyond this, decreasing the drop size reduces waste. will be
It is time for the drug regulator to look closely at these issues and ensure better quality eye drop bottles to ensure safety, efficacy and economy of use.
