Tablet Split & Dosage Calculator

Splitting pharmaceutical tablets is a common practice for titration, tapering protocols, or cost reduction. Patients often receive higher-strength tablets to divide, yet determining the precise duration of a supply or the correct split fraction leads to medication errors. Accuracy is paramount here. A deviation in splitting scored versus unscored tablets results in fluctuating blood serum levels, which is particularly risky for medications with a narrow therapeutic index. This utility computes the exact fractional requirement and forecasts the longevity of the current inventory based on the split frequency.

The mechanics of tablet splitting rely on the divisibility of the active ingredient relative to the total mass. Scored tablets guarantee a uniform distribution, whereas unscored tablets pose a risk of unequal dosing. This tool assumes a standard distribution but highlights the mathematical necessity of precise division. It provides a trajectory for inventory depletion, assisting caregivers in refilling prescriptions before a treatment gap occurs.

The calculation for the number of tablets required per dose is a simple ratio of the desired therapeutic dose to the available pharmaceutical strength. However, the inventory duration depends on the frequency of administration.

Where N_pills is the total inventory count and Freq_daily is the number of times the medication is taken per day.
