What are the differences between ibuprofen tablets and ibuprofen sustained-release capsules?

Generally, the differences between ibuprofen tablets and ibuprofen sustained-release capsules lie in the duration of action, dosing frequency, onset speed, applicable scenarios, and administration methods. Detailed analysis is as follows:

1. Duration of Action: Ibuprofen tablets are conventional formulations that release the drug quickly after entering the body, resulting in a shorter duration of action. Ibuprofen sustained-release capsules use a special sustained-release structure, allowing the drug to be released slowly and continuously in the body for a longer duration of action.

2. Dosing Frequency: Affected by the duration of action, ibuprofen tablets require more frequent dosing. Ibuprofen sustained-release capsules have a longer-lasting effect, requiring less frequent dosing, which reduces the number of doses and makes medication adherence more convenient.

3. Onset Speed: Ibuprofen tablets release the drug quickly, allowing rapid absorption into the body and a relatively faster onset. Symptoms typically improve within 30 minutes to 1 hour after administration. Ibuprofen sustained-release capsules release the drug slowly, resulting in relatively slower absorption and a slightly delayed onset of action.

4. Applicable Scenarios: Ibuprofen tablets are suitable for short-term, acute symptom relief, such as sudden headaches, toothaches, acute fever, etc., providing rapid symptom control. Ibuprofen sustained-release capsules are suitable for chronic, persistent symptom relief, such as long-term pain caused by chronic arthritis or fever requiring prolonged control.

5. Administration Methods: Ibuprofen tablets can be taken directly with water, and some formulations may be split. Ibuprofen sustained-release capsules must be swallowed whole with water and should not be split, chewed, or opened, as doing so would destroy the sustained-release structure, causing rapid drug release.

When taking either medication, the dosage must strictly follow the instructions or guidance provided to avoid overdose. Additionally, neither medication should be used for prolonged periods. For pain relief, it should not exceed 5 days, and for antipyretic use, no more than 3 days. If symptoms do not improve, the medication plan should be adjusted promptly. These medications should be stored out of reach of children to ensure medication safety.
