Preparation of Eye drops
BP506P Industrial Pharmacy I Practical
Aim: To Prepare and submit 15m1 eye drops.
Theory: Ophthalmic preparations are sterile products, essentially free from foreign particles, suitably formulated and packaged in a suitable containers for either topical application to the eyelids or instillation into the cu-de-sac between the eyeball and eyelids. Eye drops are sterile aqueous or oily solutions or suspension of one or, more medicaments intended for installation into the conjunctival sac for therapeutic purposes.
Oily eye drops are less used but may nevertheless occasionally be requested. Certain eye drops may be supplied in a drug, sterile form to be reconstituted in an appropriate sterile liquid immediately before use. In such cases, the label should state clearly on the container ‘Powder for eye drop’ and should include directions for the use of eye drops.
Aqueous eye drops contain suitable antimicrobial preservatives at the appropriate concentrations because it is intended for use on more than one occasion: The antimicrobial preservatives should be compatible with the other ingredients of the preparation and should remain effective throughout the shelf life of the eye
drops. Eyes drops sometimes do not have medications in them and are only lubricating and tear-replacing solutions. The most commonly employed ophthalmic dosage forms are solutions, suspensions and ointments.
