Introduction
Under normal circumstances, ibuprofen sustained-release capsules, as a non-steroidal anti-inflammatory drug, have functions and effects including long-acting antipyretic action, relief of chronic joint pain, reduction of muscle soreness, improvement of long-term toothache, and alleviation of persistent dysmenorrhea. When using this medication, it should be swallowed whole without breaking the capsule. The dosage must strictly follow the instructions to avoid long-term use.
Generally, as a non-steroidal anti-inflammatory drug (NSAID), ibuprofen sustained-release capsules have effects including long-lasting fever reduction, alleviation of chronic joint pain, relief of muscle soreness, improvement of persistent toothache, and mitigation of prolonged dysmenorrhea. Detailed explanations are as follows:
1. Long-Lasting Fever Reduction: Ibuprofen sustained-release capsules act on the body's temperature-regulating center, inhibiting prostaglandin synthesis to regulate abnormal body temperature. Due to the characteristics of the sustained-release formulation, the medication is slowly released, allowing the fever-reducing effect to last up to 12 hours. It is suitable for fever caused by common colds or influenza, reducing the frequency of required dosing.
2. Alleviation of Chronic Joint Pain: For chronic joint swelling and pain caused by rheumatoid arthritis, osteoarthritis, and similar conditions, this medication inhibits the release of inflammatory factors at the joints, reducing inflammatory responses. The sustained-release formulation ensures a steady drug effect, continuously relieving joint pain and swelling, thus improving joint mobility.
3. Relief of Muscle Soreness: For muscle soreness caused by exercise strain, prolonged incorrect posture, or soft tissue injury, ibuprofen sustained-release capsules can block the transmission of pain signals while reducing local muscle inflammation. Its 12-hour duration provides long-lasting relief from soreness.
4. Improvement of Persistent Toothache: If toothache persists due to conditions like gingivitis or pericoronitis, this medication can alleviate pain through its anti-inflammatory and analgesic effects. The sustained-release formulation avoids the short duration of action seen with conventional formulations, reducing the need for frequent dosing and minimizing recurrent pain.
5. Relief of Prolonged Dysmenorrhea: For persistent dysmenorrhea during menstruation caused by excessive prostaglandins in the endometrium, this medication inhibits prostaglandin synthesis, reducing the intensity of uterine contractions. The sustained-release property ensures drug action throughout the peak period of dysmenorrhea, continuously alleviating abdominal pressure and cramping pain.
When using this medication, it should be swallowed whole without breaking the capsule. Strictly follow the dosage instructions, avoid long-term use, and refrain from taking it concurrently with other medications containing antipyretic or analgesic components to ensure safe medication use.
