The bottles are used at a capacity of 10 ml or 20 ml . In only a very few instances are glass containers are used , because of stability limitations . Type 1 glass vials with appropriate stoppers are used for ophthalmic products .Fig : 10 ml amber glass dropper bottle .
Plastic packaging Currently all most all commercially available ophthalmic products are packaged in plastic containers . Advantages of plastic containers are ease of use , little breakage , less spillage . this led to universal acceptance of plastic containers. Plastic packaging components consists of bottle fitment and closure . It has multi-component single-drop dispenser. Eye drops must be sterile zed after filling into the containers and sealing , by autoclaving at a temperature of 90-100 C for 30 mins , or alternatively they may be pre sterilized and filled aseptically into previously sterilised containers . The containers are usually fitted with droppers attached to the closuers .
There are two types of dose preparations in plastic packaging Single dose preparations Multiple dose preparationsSingle dose preparations The ideal type of packaging for eye drops is a disposable one shot container which eliminates the need for any preservative and reduces the risk of infecting the eye during applications almost to zero Single dose packs are available in which the solutions can be sterilised by autoclaving in air ballasted autoclaves these solutions can therefore be formulated without a preservative . Single-use b- f-s vials, when filled under sterile conditions, have the additional advantage of enabling the product to be formulated without preservatives; most products in multi-use containers need preservatives to counteract the ingress of microorganisms after each use.
Multiple dose preparations multiple dose preparations must contain an antimicrobial preservative to prevent proliferation of contaminants during use and to support the maintenance of sterility . Examples of preservatives are phenyl mercuric nitrate or acetate , chlorhexidine acetate or benzalkonium chloride .
