Indications of Keto-D
Keto-D is a nonsteroidal anti-inflammatory drug (NSAID) indicated for the symptomatic relief of mild-to-moderate acute pain. Its use should be limited to short-term treatment.
Established/Approved Uses
- Musculoskeletal pain (e.g., muscle strains, sprains, low back pain)
- Primary dysmenorrhea (menstrual pain)
- Dental pain (e.g., post-extraction pain)
- Post-operative pain (injectable formulation, in hospital settings, usually as part of a multimodal analgesia regimen)
Other Uses (Guideline-Supported/Limited Availability)
- Renal colic (adjunct, injectable formulation, in some countries)
Keto-D is not approved by the US FDA and is not intended for long-term or chronic pain management; it treats the symptom of pain and does not address the underlying cause.
Composition
Each tablet of Dexketoprofen typically contains Dexketoprofen 12.5 mg or 25 mg (as dexketoprofen trometamol). An injectable solution containing Dexketoprofen 50 mg/2 mL (as dexketoprofen trometamol) is also available for intramuscular or intravenous use in hospital settings. Exact strength and available dosage forms may vary by manufacturer and market.
Description
Keto-D is the pharmacologically active dextrorotatory (S-(+)) enantiomer of the racemic NSAID ketoprofen. It belongs to the arylpropionic acid class of NSAIDs and provides analgesic, anti-inflammatory, and antipyretic effects by inhibiting cyclooxygenase (COX) enzymes. Keto-D is used for short-term relief of mild-to-moderate acute pain and is available as oral tablets and, in hospital settings, as an injectable solution.
Therapeutic Class
Keto-D belongs to the Non-Steroidal Anti-Inflammatory Drug (NSAID) class, specifically the arylpropionic acid (propionic acid) derivative group of non-selective cyclooxygenase (COX-1 and COX-2) inhibitors.
Pharmacology
Pharmacodynamics
Dexketoprofen non-selectively inhibits cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2) enzymes, reducing synthesis of prostaglandins that mediate pain, inflammation, and fever. As the active enantiomer of ketoprofen, Dexketoprofen provides comparable analgesic and anti-inflammatory activity at approximately half the dose of racemic ketoprofen.
Pharmacokinetics
- Absorption: Rapidly absorbed after oral administration; peak plasma concentration reached within about 15-45 minutes.
- Distribution: Highly bound to plasma proteins (approximately 99%).
- Metabolism: Primarily metabolized in the liver via glucuronidation.
- Elimination: Mainly excreted via the kidneys; elimination half-life is approximately 1-2.5 hours.
Dosage & Administration of Keto-D
Keto-D should be used at the lowest effective dose for the shortest duration necessary to control symptoms.
| Indication/Population | Dose | Notes |
|---|---|---|
| Adults - general acute pain (oral) | 12.5 mg every 4-6 hours or 25 mg every 8 hours | Maximum 75 mg per day |
| Adults - post-operative/acute pain (injection, hospital use) | 50 mg by slow IV or deep IM injection, repeated every 8-12 hours as needed | Maximum 150 mg per day; short-term hospital use only, generally not exceeding 2 days |
| Elderly | Start with the lower end of the adult dose (e.g., 50 mg/day oral) | Increase cautiously; monitor renal function |
| Mild-to-moderate renal or hepatic impairment | Reduced dose (e.g., maximum 50 mg/day) | Use with caution; contraindicated in severe impairment (see Contraindications) |
| Children/adolescents | Not recommended | Safety and efficacy not established (see Use in Special Populations) |
Oral tablets should be swallowed with a glass of water, preferably before meals for faster pain relief, though they may be taken with food if stomach upset occurs. The injectable form of Keto-D is for administration by a healthcare professional only.
Administration of Keto-D
Keto-D tablets should be swallowed whole with water, preferably about 30 minutes before meals for a faster onset of action; they may be taken with food if gastric irritation occurs. Do not crush or chew the tablet. The injectable form of Keto-D must be administered by a healthcare professional via slow intravenous or deep intramuscular injection. See Dosage and Administration for complete dosing schedules.
Interaction of Keto-D
Keto-D has clinically significant interactions with the following medicines:
| Interacting Drug/Class | Mechanism | Clinical Consequence |
|---|---|---|
| Other NSAIDs or aspirin (high dose) | Additive COX inhibition | Increased risk of GI ulceration and bleeding without added benefit; avoid concurrent use |
| Anticoagulants (e.g., warfarin) and antiplatelets | Additive effect on platelet function/bleeding risk | Increased risk of serious bleeding; monitor closely if co-administered |
| ACE inhibitors, ARBs, and diuretics | Reduced renal prostaglandin synthesis | Reduced antihypertensive effect and increased risk of acute renal impairment ("triple whammy" effect) |
| Lithium | Reduced renal clearance of lithium | Increased plasma lithium levels and risk of toxicity |
| Methotrexate | Reduced renal clearance of methotrexate | Increased methotrexate toxicity, especially at high doses |
| Corticosteroids and SSRIs | Additive GI mucosal effects | Increased risk of GI ulceration or bleeding |
| Cardiac glycosides (e.g., digoxin) | Reduced renal clearance; may worsen heart failure | Increased digoxin plasma levels; monitor cardiac status |
| Ciclosporin or tacrolimus | Additive nephrotoxicity | Increased risk of renal impairment; monitor renal function |
| Quinolone antibiotics | Additive CNS excitatory effect | Increased risk of seizures |

Patients should seek prompt medical attention for signs of a severe allergic reaction, black or bloody stools, unexplained bruising/bleeding, or yellowing of the skin or eyes.
Pregnancy & Lactation
Pregnancy
Keto-D is contraindicated during the third trimester of pregnancy due to risk of premature closure of the fetal ductus arteriosus, fetal renal impairment, and reduced amniotic fluid (oligohydramnios). Use during the first and second trimesters is not recommended unless clearly necessary; if used, the lowest effective dose for the shortest duration should be given, only if the potential benefit justifies the potential risk to the fetus, and only under medical supervision. NSAID use early in pregnancy has been associated with an increased risk of miscarriage in some studies.
Lactation
It is not known with certainty whether Keto-D passes into human breast milk in clinically significant amounts; because of the potential for adverse effects in a nursing infant, use of Keto-D during breastfeeding is not recommended. A physician should be consulted and an alternative analgesic considered before use while breastfeeding.
Precautions & Warnings
Cardiovascular Risk
NSAIDs as a class, including Keto-D, may increase the risk of serious cardiovascular thrombotic events such as myocardial infarction and stroke; this risk may increase with duration of use and in patients with existing cardiovascular risk factors or disease. Keto-D is intended for short-term use only.
Gastrointestinal Risk
NSAIDs, including Keto-D, carry a risk of serious GI adverse events, including bleeding, ulceration, and perforation of the stomach or intestines, which can occur without warning symptoms. Use the lowest effective dose for the shortest duration, particularly in elderly patients or those with a history of GI disease.
Renal Function
Use with caution in patients who are dehydrated, elderly, or taking concurrent nephrotoxic drugs, diuretics, or ACE inhibitors/ARBs; renal function should be monitored.
Fluid Retention
Fluid retention and edema have been reported; use with caution in patients with hypertension or heart failure.
Hepatic Function
Use with caution in patients with pre-existing liver disease; discontinue if signs of liver dysfunction develop.
Short-Term Use Only
Keto-D is indicated only for short-term treatment of acute pain and is not intended for chronic or long-term use, given its acute-pain indication and NSAID-class risks.
Other Precautions
- Avoid concurrent use with other NSAIDs or aspirin (including low-dose aspirin) unless specifically directed by a physician.
- May mask signs of infection (fever, inflammation).
- May cause drowsiness or dizziness; use caution when driving or operating machinery.
- Use with caution in patients with known hypersensitivity to other NSAIDs.
Overdose Effects of Keto-D
Symptoms of Keto-D overdose may include nausea, vomiting, abdominal pain, drowsiness, lethargy, headache, and, in more severe cases, gastrointestinal bleeding, hypertension, acute kidney injury, respiratory depression, and, rarely, hypotension or coma. There is no specific antidote for Keto-D overdose.
If an overdose of Keto-D is suspected, seek immediate medical attention or contact a poison control center/emergency services right away. Treatment is generally supportive and symptomatic and should be provided by trained medical personnel; do not attempt specific home treatment.
Storage Conditions
Store at room temperature (below 30°C), away from light and moisture. Keep out of reach of children.
Use In Special Populations
Renal Impairment
Use with caution and at reduced doses in mild-to-moderate renal impairment; contraindicated in severe renal impairment (see Contraindications).
Hepatic Impairment
Use with caution and at reduced doses in mild-to-moderate hepatic impairment; contraindicated in severe hepatic impairment.
Elderly
Start at the lower end of the dosing range and monitor closely, as elderly patients have a higher risk of GI, renal, and cardiovascular adverse effects with Keto-D.
Pregnancy and Lactation
See Pregnancy and Lactation section for full details.
Children and Adolescents
See Pediatric Uses section for full details.
Cardiovascular Disease
Use with caution and only after cardiovascular risk assessment in patients with pre-existing cardiovascular disease or risk factors.
Duration Of Treatment
Keto-D should be used for the shortest duration necessary to control symptoms. Oral treatment is generally not recommended beyond 5 days without medical reassessment, and injectable Keto-D is generally limited to short-term hospital use (commonly up to 2 days). Prolonged use increases the risk of gastrointestinal, renal, and cardiovascular adverse effects. A physician should be consulted if pain persists beyond the recommended duration.
Drug Classes
Dexketoprofen belongs to the Non-Steroidal Anti-Inflammatory Drug (NSAID) class, within the arylpropionic acid derivative subgroup, alongside drugs such as ketoprofen and ibuprofen.
Mode Of Action
Dexketoprofen works by non-selectively inhibiting cyclooxygenase (COX-1 and COX-2) enzymes, thereby blocking synthesis of the prostaglandins responsible for pain, inflammation, and fever. See Pharmacology for full pharmacodynamic and pharmacokinetic details.
Pediatric Uses
The safety and efficacy of Keto-D in children and adolescents under 18 years of age have not been established, and its use in this age group is generally not recommended. Keto-D should only be used in pediatric patients if specifically directed and supervised by a physician; no established pediatric dosing regimen exists.
