Let's consider the following prescription: Pheninazane tablets 50 mg with the instructions: '2 at 8 am and 10 pm on day 1, 1 at 8 am and 10 pm on day 2, and then 1 at 8 am daily thereafter.' The supply is for 56 days. To accurately determine the quantity to supply, we must break down the instructions into a clear and calculable format. The prescription for Pheninazane 50 mg tablets outlines a specific dosage regimen that requires careful calculation to ensure the patient receives the correct amount of medication over the 56-day supply period. Decoding the prescription begins with a detailed analysis of the instructions provided, paying close attention to the frequency and timing of doses. In this case, the initial days of treatment involve a higher dosage, which then tapers down to a maintenance dose for the remainder of the supply period. This tapering approach is common in many medication regimens, as it allows the body to adjust to the drug and minimizes potential side effects. Pharmacists must accurately interpret these instructions and translate them into a precise quantity of tablets to dispense. The process involves not only mathematical calculations but also a thorough understanding of pharmaceutical principles and the intent of the prescriber. By systematically breaking down the prescription, pharmacists can identify each component of the dosage regimen and calculate the total number of tablets required for the entire course of treatment. This meticulous approach ensures that the patient receives the correct medication dosage, which is crucial for achieving the desired therapeutic outcome and preventing adverse events. Effective communication between the pharmacist, prescriber, and patient is essential to clarify any ambiguities and ensure a shared understanding of the medication regimen.

1. Day 1 Dosage: The patient takes 2 tablets at 8 am and 2 tablets at 10 pm, totaling 4 tablets on day 1.
2. Day 2 Dosage: The patient takes 1 tablet at 8 am and 1 tablet at 10 pm, totaling 2 tablets on day 2.
3. Day 3 Onward: From day 3 onwards, the patient takes 1 tablet daily at 8 am. This continues for the remaining duration of the 56-day supply.
4. Calculating Remaining Days: Since the supply is for 56 days, and we've already accounted for days 1 and 2, there are 56 - 2 = 54 days remaining.
5. Total Tablets for Remaining Days: For the remaining 54 days, the patient takes 1 tablet per day, totaling 54 tablets.
6. Total Quantity: Add the tablets from day 1, day 2, and the remaining days: 4 (day 1) + 2 (day 2) + 54 (remaining days) = 60 tablets.

Step-by-step calculation is the cornerstone of accurate medication dispensing. Each step in the process must be carefully executed to avoid errors. Starting with the first day's dosage, we identify that the patient takes 2 tablets twice, resulting in a total of 4 tablets. On the second day, the dosage decreases to 1 tablet twice, totaling 2 tablets. From the third day onward, the patient takes a maintenance dose of 1 tablet daily. To calculate the total number of tablets needed for the 56-day supply, we subtract the first two days from the total duration, leaving 54 days. During these 54 days, the patient takes 1 tablet per day, resulting in 54 tablets. By adding the tablets from the first two days (4 + 2) to the tablets for the remaining days (54), we arrive at the final quantity of 60 tablets. This methodical approach ensures that all aspects of the dosage regimen are considered, minimizing the risk of miscalculation. Pharmacists must also double-check their calculations and consider any patient-specific factors that may influence the dosage requirements. Furthermore, clear documentation of the calculation process is essential for maintaining accuracy and accountability in pharmacy practice. This detailed approach not only ensures patient safety but also enhances the pharmacist's professional credibility.

Therefore, the correct quantity to supply for the 56-day prescription of Pheninazane tablets 50 mg is 60 tablets. Dispensing the correct amount of medication is a fundamental responsibility of pharmacists. In this scenario, the meticulous calculation has determined that 60 tablets are required to fulfill the 56-day prescription. This final quantity represents the culmination of a detailed analysis of the dosage instructions and a systematic calculation process. Pharmacists must ensure that the dispensed quantity aligns precisely with the calculated amount to avoid any discrepancies that could impact patient safety and therapeutic outcomes. Dispensing the wrong quantity of medication can lead to under-treatment or over-treatment, both of which can have serious consequences.
