Definition Ophthalmic preparations (eye preparations) are sterile, liquid, semi-solid, or solid preparations that may contain one or more active pharmaceutical ingredient( s) intended for application to the conjunctiva, the conjunctival sac or the eyelids. The choice of base and any excipients used for the preparation of ophthalmic preparations must be proven through product development studies not to affect adversely either the stability of the final product or the availability of the active ingredients at the site of action. The addition of colouring agents is not recommended. Unless the active ingredient itself has antimicrobial activity, ophthalmic preparations supplied as multidose preparations may include a suitable antimicrobial agent.

Differences between the ADOPTION STAGE 6 document and the current USP monograph include the following: (1) Definition—No change. (2) Packaging and storage—Storage conditions to protect from light are added. (3) USP Reference standards—A reference standard for Alcohol is added for use in the Identification test. Water —As elsewhere in the Pharmacopeia, where “water,” without qualification, is mentioned in the tests for reagents or in directions for preparing test solutions, etc., Purified Water (USP monograph) is always to be used.

The antimicrobial activity should remain effective throughout the entire period of use. The different categories of ophthalmic preparations include drops consisting of emulsions, solutions or suspensions, and ointments. Manufacture The manufacturing processes should meet the requirements of Good Manufacturing Practices, especially with regard to cross-contamination. The following information is intended to provide very broad guidelines concerning the main steps to be followed during production, indicating those that are the most important. Throughout manufacturing, certain procedures should be validated and monitored by carrying out appropriate in-process controls.
These should be designed to guarantee the effectiveness of each stage of production. In-process controls during production of ophthalmic preparations should include monitoring environmental conditions (especially with respect to particulate and microbial contamination), pyrogens (use of a limulus amoebocyte lysate (LAL) test may be advantageous), pH and clarity of solution, and integrity of container (absence of leakage, etc.). Appropriate limits should be set for the particle size of the active ingredient(s). It is essential that ophthalmic preparations are sterile.

An aseptic manufacturing process is usually employed when the dosage form does not allow routine sterilization methods to be used. 1 1 Packaging must be adequate to protect ophthalmic preparations from light, moisture, microbial contamination, and damage due to handling and transportation.
