What is a Generic Drug?

A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.

The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (eg. different shape or color), as trademarks laws prevent a generic from looking exactly like the brand-name drug.

Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.

  • Product Details


    ACULAR LS (ketorolac tromethamine) is an ophthalmic medication used after different types of eye surgery. 

    ACULAR LS belongs to the medication class non-steroidal anti-inflammatory (NSAID). NSAIDs like ACULAR LS reduce pain, inflammation, swelling, and redness where they are applied. Ketorolac works by blocking the enzymes cyclooxygenase 1 and cyclooxygenase 2. Blocking these enzymes prevents cells of the immune system from activating. 

    ACULAR LS is used after the following surgeries: cataract extraction, corneal refractive surgery, and cataract surgery. It can also be used to treat ocular itching that occurs with seasonal allergies.


    Instill one drop to the affected eye(s) four times daily or as directed by your doctor. Sometimes ACULAR LS is applied only twice daily.

    Do not touch the tip of the dropper directly onto the eye. Contact with the eye can cause contamination by viruses or bacteria, which can lead to eye infections.

    Remove contact lenses before applying and wait at least 10 minutes before putting them back in.


    The active ingredient in ACULAR LS is ketorolac tromethamine 0.4%. 

    The name for ACULAR LS generic is also ketorolac tromethamine.


    Since eye medications are not absorbed into the bloodstream, they do not have drug interactions with most other medications.

    However, when using other eye drops, separate their administration by at least five minutes.
