The term Po (by mouth) q24 (every 24 hours) means taking a medication orally (by mouth) once daily.
- Po is an abbreviation for the Latin phrase "per os," which means by mouth.
- q24 is an abbreviation for the Latin phrase "quaque 24 hora," which means every 24 hours or once daily.
This is equivalent to the QD (once daily) dosage regimen mentioned in the drug label 1.
From the Research
Po q24 means "by mouth every 24 hours" in medical terminology, indicating that a medication should be taken orally once per day, with doses spaced approximately 24 hours apart. This instruction is crucial for maintaining consistent blood levels of the medication throughout the treatment period, which helps ensure therapeutic effectiveness while minimizing potential side effects 2. The "po" route specifies that the medication should be swallowed rather than administered through other routes such as intravenous, intramuscular, or topical application.
Key Points to Consider
- The medication should be taken orally once per day, with doses spaced approximately 24 hours apart.
- The "po" route is essential for maintaining consistent blood levels of the medication throughout the treatment period.
- Following this schedule is important for ensuring therapeutic effectiveness while minimizing potential side effects.
Importance of Adherence to Po q24 Instruction
Adhering to the Po q24 instruction is vital for achieving optimal therapeutic outcomes. As noted in a study on the optimal time to take once-daily oral medications, the administration time-dependent efficacy of drugs can vary depending on the type of drug, pathophysiologic status, clinical symptoms, and patient feedback 2. Therefore, it is essential to follow the recommended dosing schedule to ensure the medication's effectiveness and minimize potential side effects.
Relevance to Medication Administration
The Po q24 instruction is relevant to various medications, including those used to treat chronic conditions such as diabetes and cardiovascular disease. For example, a study on the efficacy and safety of atorvastatin in preventing cardiovascular end points in subjects with type 2 diabetes found that once-daily dosing was effective in reducing LDL cholesterol levels and preventing cardiovascular events 3. Similarly, another study on the effect of once-daily fluticasone furoate/vilanterol on 24-hour pulmonary function in patients with chronic obstructive pulmonary disease found that once-daily dosing improved pulmonary function and was well-tolerated 4.
