Overview of Alidol F

Quick Facts

Property Description
Active ingredient Ibuprofen (INN)
Form Tablet / Film-coated tablet (Oral administration)
Pharmacological class Nonsteroidal Anti-inflammatory Drug (NSAID)
Common use General relief of pain, inflammation, and fever
Origin Synthetic (Propionic acid derivative)

1. The Core Identity: What Type of Medicine is Alidol F?

Alidol F is a specific pharmaceutical product whose entire therapeutic identity is defined by its core active ingredient, Ibuprofen (INN). Ibuprofen is a synthetic compound, a derivative of propionic acid, and this composition places the drug squarely within the Nonsteroidal Anti-inflammatory Drug (NSAID) class. This medicine is clinically recognized for its anti-inflammatory effects, a property supported by numerous pharmacological studies.

Alidol F is typically manufactured as a single-component product, relying exclusively on the Ibuprofen mechanism, which involves modulating the enzymes responsible for generating inflammatory mediators. This focus distinguishes its action as singular and predictable within the NSAID framework.

2. Form and Composition: What is the Ibuprofen Tablet Made Of?

Alidol F is intended for oral administration and is typically presented as a solid dosage form, most commonly a tablet or film-coated tablet. This structure is fundamental to the medicine's identity and is achieved by blending the active Ibuprofen substance with necessary, inert pharmaceutical excipients.

These excipients, which include stabilizers and binding agents, ensure the product's quality, stability, and predictable disintegration in the digestive system for systemic delivery. The tablet form ensures that the active Ibuprofen is delivered systemically. The final medicine, in its tablet form, is confirmed to exhibit potent analgesic, anti-inflammatory, and antipyretic activity in humans. The body uses this medicine to achieve generalized pain and fever relief by intervening in the underlying inflammatory process.

3. General Therapeutic Utility: What is Alidol F Generally Used For?

The general therapeutic utility of Alidol F is a direct consequence of its consistent NSAID mechanism. The preparation is employed to provide overall analgesic effects (pain relief), reduce localized inflammation, and exert an antipyretic effect (fever reduction). This confirms the drug's broad utility in generally helping to reduce pain and fever symptoms.

In functional terms, the substance is used to counteract the biological processes that cause tissue swelling and sensitize nerve endings. By modulating the central thermoregulatory center through the inhibition of prostaglandin synthesis, Alidol F generally assists the body in returning an elevated temperature to a normal physiological range.

What side effects are possible with Alidol F?

Possible side effects and safety information

The safety profile of Alidol F, which contains Ibuprofen, is defined by adverse reactions categorized by frequency and the body system affected, strictly following official government regulatory classifications. The medicine is associated with risks across several System-Organ Classes, primarily the gastrointestinal and cardiovascular systems.


Official Adverse Reaction Classification

Adverse effects are listed according to their estimated frequency, as specified in regulatory documents:

  • Common (affects 1 to 10 users in 100): Gastrointestinal reactions such as dyspepsia, nausea, and abdominal pain, as well as headache.
  • Uncommon (affects 1 to 10 users in 1,000): Includes diarrhea, flatulence, vomiting, skin rash, and nervous system effects like dizziness or insomnia.
  • Rare (affects 1 to 10 users in 10,000): Documented serious events such as aseptic meningitis, visual disturbances, and forms of renal failure.

Documented Serious Safety Risks

Official labeling emphasizes the risk of serious adverse reactions, which can occur at any time during use. These include major Gastrointestinal Ulceration, Bleeding, and Perforation. The profile also details the risk of serious Cardiovascular Thrombotic Events, such as Myocardial Infarction (heart attack) and Stroke, risks which may increase with the duration of use and the administered dose, as stated in FDA labeling. Furthermore, the risk of adverse reactions, particularly gastrointestinal bleeding, is officially noted to be increased in older adults.

Overdose and Emergency Response

The official regulatory profile for Alidol F (Ibuprofen) overdose outlines recognized clinical manifestations that primarily involve the gastrointestinal (GI) and central nervous systems (CNS).

Documented GI signs include nausea, vomiting, abdominal pain, and diarrhea. CNS effects reported in regulatory labeling encompass headache, dizziness, drowsiness, lethargy, tinnitus, blurred vision, and confusion.

Serious or life-threatening outcomes reported in official documents include seizures, coma, metabolic acidosis, and severe cardiovascular effects such as hypotension. Systemic complications may involve acute renal failure, hepatotoxicity, and potentially fatal gastrointestinal bleeding or perforation. Regulatory sources also note that elderly patients face a greater risk for serious GI events in overdose scenarios.

In the event of a suspected overdose—defined as taking more than the maximum dose—immediate medical attention must be sought, even if symptoms are not yet present. Regulatory authorities require that a Poison Control Center be contacted right away. If severe symptoms such as difficulty breathing, sudden weakness, or slurred speech occur, emergency services must be called.

Treatment is officially classified as symptomatic and supportive care. No specific antidote is known; management typically includes hospital observation, vital sign monitoring, and procedures like the administration of activated charcoal.

Therapeutic Uses of Alidol F

Alidol F is commonly used across therapeutic domains involving symptomatic discomfort, including conditions presenting with mild to moderate pain, inflammation and swelling, and systemic fever. It is relevant when supportive symptom management is appropriate in acute episodes, such as those involving headaches, menstrual cramps, and joint stiffness.

“The medication provides supportive relief that generally helps patients cope more steadily with difficult episodes and periods of heightened physical discomfort.”


Relief from Acute and Cyclical Pain

Alidol F is applied to ease various acute and recurrent scenarios, including common headaches, muscular aches, and the cramping associated with painful menstrual periods. This support provides comfort, supports the patient during difficult episodes by easing distress, and may assist with maintaining functional stability.


Symptomatic Support for Inflammatory Conditions

The medicine is relevant for easing the physical signs of inflammation and pain related to chronic conditions like osteoarthritis and acute presentations such as sprains or localized swelling. Its use supports management of the overall symptom load and supports general well-being during symptomatic periods by easing challenging symptoms related to persistent joint stiffness.

Eligibility and Restrictions for Use

Population Eligibility for Alidol F (Ibuprofen)

Official regulatory documents define strict criteria regarding who can and cannot use Alidol F, based on age, specific medical history, and physiological status.


Category Regulatory Status / Restriction
Populations for whom use is allowed Established for use in adults and adolescents (ge 12 years) under standard labeled conditions, provided no contraindications are present [Source 2.1]. Use is established for children ge 6 months (typically for fever and pain, often using specific liquid or chewable dose forms) [Source 1.3].
Populations for whom use is not recommended Infants younger than 6 months of age are generally not recommended for standard oral tablet use as safety and efficacy are not established [Source 1.3]. Use in women after 20 weeks of pregnancy is not recommended (avoid unless advised by a healthcare professional) [Source 2.2].
Populations for whom use is contraindicated Absolute prohibition for patients with a history of hypersensitivity to Ibuprofen, aspirin, or other NSAIDs; active or recurrent peptic ulcer/GI haemorrhage (ge 2 distinct episodes); severe heart failure (NYHA Class IV); severe hepatic failure; severe renal failure; and women in the third trimester of pregnancy (ge 30 weeks gestation) [Source 1.1, 1.3, 3.4].

Condition-Based Eligibility Rules

  • Cardiovascular Conditions: Use in patients with uncontrolled hypertension, congestive heart failure (NYHA Class II-III), established ischaemic heart disease, peripheral arterial disease, and/or cerebrovascular disease requires careful consideration, and high doses (ge 2,400 mg/day) should be avoided [Source 3.5].
  • Organ Impairment: Patients with mild to moderate hepatic impairment or renal impairment require caution; function must be monitored [Source 3.1, 3.4].
  • Geriatric Use: Elderly patients (ge 65 years) are a Restricted/Conditional Use population due to an increased risk of adverse reactions, requiring particular caution and monitoring [Source 2.5, 3.1].
  • Lactation: The medicine is generally considered compatible with breastfeeding as regulatory data suggests it passes into breast milk in very low concentrations [Source 1.2, 2.5].

What should I know about interactions with other medicines?

The regulatory profile for Alidol F (Ibuprofen) identifies several clinically significant interaction patterns, particularly those affecting bleeding risk and drug clearance.

Contraindicated and High-Risk Combinations

The profile establishes restrictions on co-administration due to the risk of serious adverse events. Co-administration with other nonsteroidal anti-inflammatory drugs (NSAIDs), including COX-2 inhibitors, is formally restricted due to an increased risk of gastrointestinal (GI) bleeding and ulceration. Combining Alidol F with anticoagulants (such as Warfarin) or corticosteroids increases the risk of bleeding due to a pharmacodynamic, additive antiplatelet effect.

Exposure Modification

The medicine affects the plasma concentrations of certain co-administered drugs by reducing their renal clearance. This can lead to elevated plasma levels of substances like Lithium and Methotrexate, as officially documented in labeling, increasing the potential for toxicity of these substances.

Efficacy and Timing Constraints

Ibuprofen can reduce the therapeutic efficacy of some medications. This is observed in combination with anti-hypertensives (including ACE inhibitors and ARBs) and diuretics, whose intended blood pressure-lowering or fluid-reducing effects may be diminished. For patients requiring low-dose Aspirin, official documents suggest a separation of administration time to mitigate potential interference with its antiplatelet effect. Furthermore, consumption of three or more alcoholic drinks per day is officially associated with an increased risk of severe GI bleeding. Elderly patients (age 60 or older) are noted to be at a heightened risk for severe interaction-related complications.

Mechanism of Action

Reversible Inhibition of Cyclooxygenase (COX) Enzymes

The active component of Alidol F, Ibuprofen, functions as a non-selective, reversible inhibitor of both Cyclooxygenase-1 ( COX-1) and Cyclooxygenase-2 ( COX-2) enzymes. This action involves the pharmacologically potent S-enantiomer blocking the active site of both isoenzymes. This molecular interference prevents the conversion of arachidonic acid into prostaglandins and other prostanoid mediators, thereby blocking the critical first step in the arachidonic acid cascade. This biochemical blockade modifies early molecular steps within systemic physiological cascades.

Modulation of Peripheral Signaling and Central Set Point

By reducing the local concentration of prostaglandins, the drug alters the signaling dynamics within peripheral nociceptive pathways. Prostaglandins function to sensitize peripheral nerve fibers and modulate local vascular permeability. The reduction of these mediators causes a lower level of chemical input to peripheral nerve fibers, resulting in decreased sensitization and modulation of vascular responses in local tissues. The mechanism also extends centrally: inhibition of PGE2 synthesis within the hypothalamus prevents the upward shift of the thermal set point induced by pyrogenic signals, engaging a mechanism that permits the stabilization of the thermal set point.

Dosage and Administration Information

Recent Clinical Evidence

Research Evidence / Overview of Studies for Alidol F

Evidence for Use in Acute Pain and Symptom Relief

Research examining Alidol F for acute pain and symptom relief has a foundation of study. This body of evidence primarily includes short-term Randomized Controlled Trials (RCTs) and large-scale meta-analyses that observed the medicine in research contexts involving fluctuating or unstable symptoms. Studies were conducted during periods of increased symptom activity and focused on outcomes related to physical discomfort. Researchers examined populations facing conditions associated with acute or disruptive episodes, such as headache, dental pain after procedures, musculoskeletal injuries, and painful menstrual periods (dysmenorrhea).

Studies report how symptoms evolved in the observed populations, describing patterns of measured pain change, particularly in the immediate hours following administration. The structure of the evidence base across these acute pain research contexts is frequently characterized as High-level.


Evidence for Use in Managing Elevated Body Temperature (Fever)

Research exploring how symptoms related to elevated body temperature (fever) change over time relies on a consistent structure of Randomized Clinical Trials (RCTs) and systematic reviews. These studies explored research examining temporary physiological imbalance and were often designed as trials comparing it against other agents. The studies monitored outcomes related to systemic or functional imbalance by measuring the degree of temperature change and the time required to achieve a more normalized temperature.

Evidence indicates that studies report measured changes in elevated body temperature across both adult and pediatric populations. Research exploring temporary physiological imbalance describes patterns of change observed during defined time intervals, focusing on time points up to six hours post-dose.


Identified Research Gaps and Remaining Uncertainty

While the research base has a foundation of study for many acute uses, several research limitations exist:

  • Long-term effects are not fully established regarding the sustained symptomatic changes, as follow-up durations were limited for some outcome measures.
  • Data for certain groups remain insufficient, particularly for patients with unique comorbidities or for comparative evidence against all emerging alternative therapies.
  • The findings describe group patterns, not personal outcomes; research does not determine whether an individual will respond similarly, as study results reflect the specific conditions under which they were conducted.
