Ratios

    A ratio. or two numbers related to one another, can be separated by a colon, 1:40, or written as a fraction, 1/40. Ratios are commonly used to indicate the weight or strength of a medication in a capsule or tablet.

    Example: 125:1 capsule or 125/1 capsule

    Reminder: ratios are used to express medication dosages in liquid medications, both injectable and oral solutions. The ratio indicates the weight or strength of the medication in a specific volume of solution.

    Example: 2 mL: 60 mg or 2mL/60 mg

    In other words: 2mL contains 60 mg of the prescribed medication.
