Information about Ibuprofen
Ibuprofen is a non-steroidal anti-inflammatory drug (NSAID) widely used for the treatment of pain, inflammation, and fever. It belongs to the category of propionic acid derivatives.
Active ingredients: Ibuprofen
Therapeutic category: Non-steroidal anti-inflammatory drugs (NSAIDs)
Chemical structure: C₁₃H₁₈O₂
Mechanism of action: Ibuprofen works by inhibiting the action of cyclooxygenase enzymes (COX-1 and COX-2), thereby reducing the production of prostaglandins responsible for pain, inflammation, and fever.
History of the drug
Ibuprofen was initially developed in the early 1960s in the United Kingdom. Its discovery marked a significant milestone in the history of analgesic drugs, offering an effective alternative with fewer side effects compared to aspirin.
As noted by Irvine in his research, ibuprofen has significantly evolved from its original form, with the development of various formulations and administration methods that optimize its effectiveness. The drug was initially released as a prescription medication but later became available over-the-counter due to its excellent safety profile.
Research to improve administration methods and develop new forms of the drug continues with unabated interest in the scientific community, as it is one of the most widely used drugs worldwide.

Interactions
Ibuprofen is a widely used drug that can interact with various substances. According to Ahmed, understanding these interactions is crucial for the safe use of the drug. Patients should always inform their healthcare provider about all medications they are taking, including over-the-counter drugs and dietary supplements.
Drug-drug interactions
Ibuprofen significantly interacts with various drug categories. Special caution is required when co-administered with anticoagulant drugs, as the risk of bleeding increases. Concurrent use with other NSAIDs should be avoided due to an increased risk of gastrointestinal complications. As noted by Osman in his research, co-administration with antihypertensive drugs may reduce their effectiveness. Additionally, use with diuretics may increase the risk of renal failure, while co-administration with lithium may lead to increased blood levels of lithium.
Drug-food interactions
Taking ibuprofen with food can affect its absorption and effectiveness. It is recommended to take it with food or milk to minimize gastric irritation. Alcohol consumption during treatment should be avoided as it increases the risk of gastrointestinal complications. Foods rich in potassium may interact with the drug, especially in patients with renal dysfunction. Excessive caffeine consumption may enhance the drug’s adverse effects on the central nervous system. Caution is also advised when consuming foods containing high levels of sodium, as ibuprofen may cause fluid retention.
Additional important information
Ibuprofen is one of the most widely used drugs worldwide, with extensive use both as a prescription and over-the-counter medication. Its effectiveness in treating pain and inflammation has been extensively documented. However, long-term use requires special attention and regular medical monitoring.
According to a comprehensive study by Ribeiro, the drug should be stored at room temperature, away from direct sunlight and moisture. Additionally, as indicated by Yatimzade and colleagues, proper waste management of the drug is critical for environmental protection. Noteworthy is the research by Afrose highlighting the importance of proper packaging for maintaining the drug’s stability.
Development of resistance
The development of resistance to ibuprofen is a complex phenomenon that requires special attention. Continuous and long-term use of the drug may lead to reduced effectiveness as the body adapts to the presence of the substance. This phenomenon is particularly important for patients with chronic conditions requiring regular use of the drug.
Managing resistance requires careful dosage adjustment and periodic evaluation of the drug’s effectiveness. In some cases, temporary discontinuation of use or switching to other analgesic drugs may be necessary to avoid the development of resistance. Regular communication with the healthcare provider is essential for optimal treatment management.
Preclinical and Clinical Studies
Preclinical studies of ibuprofen have demonstrated the drug’s effectiveness and safety in various experimental models. Toxicity studies in animals have determined the therapeutic range and potential side effects. Understanding the mechanism of action has significantly improved in recent years. According to laboratory findings by George and colleagues, the inhibition of prostaglandin synthesis is the main mechanism of action of the drug.
Post-marketing studies, Pharmacovigilance, and Pharmacokinetic characteristics
In an extensive analysis of post-marketing data, as presented by Martins Moreira, ibuprofen exhibits a remarkable safety profile. The pharmacovigilance system has significantly contributed to recording and evaluating adverse effects after the drug’s market release.
The pharmacokinetic characteristics of the drug have been extensively studied. Rathnanand points out that the absorption of ibuprofen from the gastrointestinal system is rapid and almost complete. The drug binds to a high percentage of plasma proteins and is primarily metabolized in the liver. Excretion is mainly through the kidneys, with a half-life ranging between 1.8 and 2 hours.
Continuous monitoring and evaluation of safety data through pharmacovigilance systems allow for the timely identification of potential risks and the immediate implementation of measures to protect public health.
Preclinical and Clinical Studies
Ibuprofen has undergone extensive preclinical and clinical studies to evaluate its safety and effectiveness. Initial preclinical studies focused on understanding the mechanism of action and determining the optimal dosage. Experimental models have confirmed the anti-inflammatory and analgesic action of the substance through the inhibition of cyclooxygenase enzymes.
The research efforts of Acosta-Reyes have significantly contributed to understanding the therapeutic applications of ibuprofen in various clinical conditions.
Post-marketing studies, Pharmacovigilance, and Pharmacokinetic characteristics
After the approval of ibuprofen, extensive post-marketing studies have provided valuable data on the long-term safety and effectiveness of the drug. As indicated by the team of Ealias, pharmacovigilance systems have highlighted important information regarding rare side effects and interactions with other drugs.
The pharmacokinetic characteristics of ibuprofen include rapid absorption from the gastrointestinal system, with peak plasma concentrations achieved within 1-2 hours after ingestion. The drug undergoes extensive first-pass metabolism in the liver, with the main metabolites excreted through the kidneys. The bioavailability of the drug is affected by various factors, including food intake and liver function.
Comparative effectiveness
Ibuprofen has been extensively evaluated in comparison with other analgesic and anti-inflammatory drugs. According to findings presented by Kayani, its effectiveness is comparable to other NSAIDs in managing pain and inflammation, while it presents a more favorable safety profile in certain cases.
Systematic reviews and meta-analyses
In a systematic review conducted by the research team of Ahmadpour, the effectiveness of ibuprofen in managing various types of pain was highlighted. The results of meta-analyses support its use as a first-line drug for acute pain.
Current research directions and future prospects
Current research, as mentioned by Krivoshapkin, focuses on developing new forms of ibuprofen administration that will optimize bioavailability and minimize side effects. Research also aims to understand molecular mechanisms of action and develop personalized therapeutic approaches. Future prospects include exploring new therapeutic indications and improving the drug’s safety in special populations.
Summary
Ibuprofen is a widely used non-steroidal anti-inflammatory drug with multiple therapeutic applications. It is mainly used for managing pain, inflammation, and fever, with particular effectiveness in musculoskeletal disorders and headaches. Its administration is contraindicated in cases of gastrointestinal ulcers, severe renal or hepatic failure, and during the third trimester of pregnancy. Caution is required when co-administered with anticoagulant and antihypertensive drugs. The most common side effects include gastrointestinal disturbances, while allergic reactions or renal dysfunction may occur less frequently.
