Property Description
Active ingredient Ketoprofen (Racemic mixture)
Common Forms Oral Capsules/Tablets, Topical Gel, Injectable Solution
Pharmacological Class Non-steroidal Anti-inflammatory Drug (NSAID)
General Purpose Symptomatic relief of pain, inflammation, and fever
Origin Synthetic (Propionic acid derivative)

What Type of Medicine is Ketoplus?

Ketoplus is the commercial designation for a medicine containing the active ingredient Ketoprofen, which fundamentally belongs to the Non-steroidal Anti-inflammatory Drug (NSAID) pharmacological class. This medication is a synthetic compound derived from propionic acid, classifying it alongside other agents used to manage discomfort and swelling. Its classification as an NSAID establishes its core role in mediating the body's pain and inflammatory responses. Ketoprofen is clinically recognized for its reliable efficacy across various pain conditions.

Composition, Forms, and General Purpose

The core component of the product is the Ketoprofen compound, which is typically administered as a racemic mixture containing both the (R)- and (S)-enantiomers, although the (S)-enantiomer is the primary biologically active form. As a single-ingredient product, Ketoprofen is prepared for various routes of administration, most commonly as oral capsules or tablets for systemic effects, or as a topical gel for localized action. The general therapeutic purpose is to provide effective symptomatic relief by broadly combating the related physiological responses of pain, inflammation, and fever.

How Does Ketoprofen Differ from Common Analgesics?

Ketoprofen offers a more robust therapeutic profile compared to simple pain relievers because it functions as a triple-action agent, possessing strong analgesic, anti-inflammatory, and antipyretic properties. Its primary mechanism involves non-selective inhibition of cyclooxygenase (COX) enzymes, which are the targets for reducing the production of chemical mediators responsible for pain and swelling. This shows the medicine doesn't just block pain signals, but also actively helps reduce the physical cause of swelling and inflammation. Pharmacological studies consistently confirm Ketoprofen's efficacy in addressing conditions like acute musculoskeletal strain, making its combined anti-inflammatory and pain relief profile a key differentiating factor.

What side effects are possible with Ketoplus?

Possible Side Effects and Safety Information

The information below outlines the officially documented adverse reactions and safety restrictions for Ketoplus, as detailed in regulatory documents from major government health authorities.

Serious and Clinically Significant Safety Concerns

The regulatory safety profile for Ketoplus focuses on the potential for Serious Organ Toxicity and life-threatening complications. Government health authorities have placed strong warnings on two primary risks:

  • Hepatotoxicity (Severe Liver Injury): Cases of severe liver damage, including those leading to liver transplantation or death, have been documented. This risk exists even at approved dosages and with both short- and long-term use. Routine monitoring of liver function tests is mandatory.
  • QT Prolongation and Ventricular Arrhythmias: The medicine can affect the heart's electrical rhythm (QT prolongation), leading to life-threatening ventricular dysrhythmias, such as Torsades de Pointes. This risk is primarily amplified by taking Ketoplus with other specific medicines that elevate its plasma concentrations.

Other Regulatory Safety Concerns

  • Endocrine System Dysfunction: The medicine is associated with the risk of Adrenal Insufficiency, a condition where the adrenal glands do not produce adequate amounts of cortisol.
  • Common Adverse Reactions: Adverse reactions frequently reported in clinical data include gastrointestinal issues such as nausea and vomiting.

Safety-Related Restrictions (Contraindications)

Ketoplus is contraindicated (must not be used) in patients with specific conditions, as its use is prohibited due to unacceptable safety risks:

  • Patients with acute or chronic liver disease.
  • Patients taking specific other medicines that are known to significantly increase the plasma concentration of Ketoplus or are known to prolong the QT interval.

Overdose and Emergency Response

Ketoprofen overdose is officially documented by a range of manifestations, primarily affecting the gastrointestinal and central nervous systems. Initial clinical signs listed in regulatory information include nausea, vomiting, abdominal pain, diarrhea, drowsiness, dizziness, and headache. Less common but officially noted sensory effects include ringing in the ears (tinnitus) and blurred vision.

A large ingestion of Ketoprofen carries the risk of severe, life-threatening outcomes. The regulatory profile explicitly notes the potential for acute renal failure, severe gastrointestinal bleeding, and neurological events such as seizures and coma. Cardiovascular stability can be affected, sometimes presenting as hypotension or hypertension. Death may occur in severe, large overdoses, and a large overdose can cause serious damage to children and adults.

Since no specific antidotes are known, official regulatory guidance mandates that treatment is strictly symptomatic and supportive. Individuals must seek immediate medical help right away and contact emergency services or a poison control center in any suspected overdose. To manage the condition, procedures described in regulatory documents include GI decontamination (e.g., activated charcoal) and continuous monitoring of vital signs under clinical observation. This is especially critical for sustained-release formulations which may require a longer decontamination window.

Therapeutic Uses of Ketoplus

Ketoplus is considered relevant for symptom management across therapeutic domains involving heightened physiological responses. This medication is commonly used to help with symptoms related to physical discomfort, inflammation, and fever.

The medication is applied across domains where additional symptomatic support is needed for conditions presenting with systemic or localized discomfort, including Osteoarthritis, Rheumatoid Arthritis, and Ankylosing Spondylitis. It is relevant for easing long-term joint pain, tenderness, and stiffness. By easing these persistent manifestations, the medication provides supportive relief that contributes to improved day-to-day comfort and helps ease the overall symptom load when discomfort affects functional stability.

Ketoplus is also commonly used to help with symptoms related to heightened physiological activity during sudden inflammatory flare-ups, such as acute gout, or in situations involving episodic discomfort, like primary dysmenorrhea or headaches. This usage provides supportive relief that may assist with maintaining functional stability and may help patients cope more steadily with symptom fluctuations.


Quick Fact: Use for Inflammation and Acute Discomfort Ketoprofen is commonly used to address groups of symptoms that may appear suddenly or fluctuate, providing symptomatic assistance in settings marked by temporary symptom patterns.

Eligibility and Restrictions for Use

Who Can and Cannot Use Ketoplus? (Official Regulatory Information)


Contraindicated Populations

Use of Ketoprofen is strictly contraindicated in patients with a known hypersensitivity to the medicine or to other NSAIDs, which includes those with aspirin-induced asthma or urticaria. It is also prohibited for individuals with active gastrointestinal bleeding or ulceration, severe heart failure, severe hepatic insufficiency, or severe renal insufficiency. Regulatory documents strictly forbid its use during the third trimester of pregnancy and in the setting of peri-operative pain for Coronary Artery Bypass Graft (CABG) surgery.


Age-Related and Conditional Eligibility

The prescription label states that safety and effectiveness have not been established in the pediatric population (patients under 18 years). Older adults are eligible but require caution due to a greater risk for serious cardiovascular and gastrointestinal events. Patients with mild to moderate renal or hepatic impairment require caution and may be restricted to lower doses and subject to increased monitoring. Use during the first and second trimesters of pregnancy should be avoided unless essential, and use while breastfeeding is generally not recommended.

What should I know about interactions with other medicines?

Interactions with other medicines and products

Official regulatory documents define the interaction profile of Ketoplus based on pharmacodynamic risk and changes in drug clearance. Co-administration with Oral Anticoagulants, Antiplatelet agents, Selective Serotonin Reuptake Inhibitors (SSRIs), and Oral Corticosteroids results in an additive pharmacodynamic risk of serious gastrointestinal adverse events, including bleeding and ulceration. Additionally, the drug interferes with the effects of Diuretics, ACE Inhibitors, and ARBs, reducing their antihypertensive or diuretic efficacy and increasing the documented potential for acute renal failure.

The interaction profile includes substances that experience decreased renal clearance when co-administered. Specifically, this effect may lead to elevated blood lithium levels and increased plasma concentrations of Methotrexate. Regulatory guidance mandates specific timing separation for Methotrexate administration. The medicine is formally contraindicated for use in managing perioperative pain associated with CABG surgery.

Non-medicinal substance interactions are also documented: consumption of Alcohol enhances the risk of serious gastrointestinal bleeding. While the total exposure is not altered by food intake, the rate of absorption may be slowed. Elderly patients are documented to have a greater risk for serious gastrointestinal adverse events, and those with chronic liver disease may require consideration due to altered pharmacokinetics.

Mechanism of Action

Dual Targeting: Fungal Membrane Synthesis and Metabolic Function

Ketoplus operates primarily by a dual-action mechanism that targets essential metabolic and structural processes in fungal and yeast cells. The first component, Ketoconazole, acts as an inhibitor of the fungal enzyme Lanosterol 14alpha-demethylase (CYP51A1), which blocks the conversion of lanosterol into ergosterol and compromises the structural integrity of the cell membrane. The second component, Zinc Pyrithione, interferes with the cell's membrane transport and DNA/biosynthesis, leading to an alteration in metabolic function and replication signaling.


Mechanistic Cascade and Physiological Modulation

This combined molecular interference initiates a cascade leading to the suppression and clearance of the pathogenic micro-organism. This action modulates the cascade of cellular responses initiated by the presence of the micro-organism. This targeted peripheral action contributes to a reduction in epidermal cell proliferation and influences the activity of localized inflammatory pathways, leading to modulations in physiological processes that are a consequence of the underlying mechanistic action.

The procedural structure dictates the frequency of use (daily versus as-needed), specifies conditions of oral intake, and establishes dose limitations for specific populations, such as reduced maximum doses for patients with renal or hepatic impairment.

Recent Clinical Evidence

Research evidence / Overview of Studies for Ketoplus

Research describing Ketoprofen (Ketoplus) was derived from mainly randomized controlled trials (RCTs), comparative efficacy trials, and systematic reviews used in research exploring how symptoms change over time in specific clinical situations.


Evidence for Managing Chronic Joint Conditions

This section summarizes the research base, including Randomized Controlled Trials (RCTs) and systematic reviews, where Ketoprofen was evaluated in research involving chronic joint conditions. This research is relevant in research contexts involving fluctuating or unstable symptoms, and studies focused on the outcomes monitored in these areas.

Research for Osteoarthritis and Rheumatoid Arthritis

Studies involving Ketoprofen explored Osteoarthritis and Rheumatoid Arthritis, drawing on numerous RCTs and meta-analyses. Researchers primarily studied adult populations with confirmed diagnoses and examined outcomes related to physical discomfort, joint swelling, and overall daily functioning. In the context of Rheumatoid Arthritis, studies examined outcomes related to the duration of morning stiffness and grip strength assessments. Findings describe patterns observed in the studies regarding how patients reported their experience and activity levels.

Research highlights that the evidence mainly addresses symptomatic changes over intermediate follow-up durations (e.g., 4 to 12 weeks), and there is limited information for long-term outcomes related to underlying disease progression.


Evidence for Treating Acute Discomfort

This section will outline research relevant in trials assessing short-term or episodic symptom patterns, focusing on conditions associated with acute or disruptive episodes.

Trials for Acute Systemic Pain

Ketoprofen was observed in numerous short-term, often single-dose, placebo-controlled RCTs involving acute pain, including post-operative pain and headaches. Research examined outcomes describing episodic or acute changes, such as the time it took for patients to report relief and the overall measured reduction in pain intensity over the first few hours. Findings describe group patterns of symptom response measured during the study period.

Evidence for Topical Formulations

Ketoprofen was studied for acute musculoskeletal pain using topical formulations (e.g., gels or patches) in placebo- or vehicle-controlled RCTs. Research examined outcomes linked to inflammatory or irritative states, including the measurement of patient-reported outcomes describing perceived discomfort and the assessment of functional outcomes at the injury site. Findings indicate patterns observed in the studies regarding localized symptom responses compared to controls.


What is Still Uncertain About Ketoprofen Research

Research describes limitations that are continuing to be explored. The follow-up durations were limited in many pivotal studies, meaning long-term effects on functional outcomes or the maintenance of observed patterns are not fully established. Additionally, the evidence quality varies across studies, and some trials used older comparators, which may limit the relevance of those findings to current research contexts. Subgroup findings for specific populations with comorbid conditions are uncertain.
