Dabigatran Etexilate Laboratorios Liconsa: Uses, Dosage & Side Effects
A direct thrombin inhibitor (anticoagulant) used to prevent stroke in atrial fibrillation, treat and prevent venous thromboembolism, and prevent blood clots after joint replacement surgery
Dabigatran etexilate Laboratorios Liconsa is a generic formulation of the direct oral anticoagulant dabigatran etexilate, used to prevent blood clots in a range of clinical settings. As a direct thrombin inhibitor, it works by blocking the activity of thrombin, a central enzyme in the coagulation cascade responsible for converting fibrinogen into fibrin clots. This medication is primarily prescribed to reduce the risk of stroke and systemic embolism in adults with non-valvular atrial fibrillation, to treat and prevent recurrence of deep vein thrombosis (DVT) and pulmonary embolism (PE), and to prevent venous thromboembolism following elective hip or knee replacement surgery. Unlike warfarin, dabigatran does not require routine coagulation monitoring and has fewer dietary and drug interactions, representing a significant advance in anticoagulation therapy.
Quick Facts: Dabigatran Etexilate
Key Takeaways
- Dabigatran etexilate Laboratorios Liconsa is a generic direct oral anticoagulant (DOAC) that directly inhibits thrombin, the key enzyme in the blood clotting cascade, providing predictable anticoagulation without routine blood monitoring.
- The medication is indicated for stroke prevention in non-valvular atrial fibrillation, treatment and secondary prevention of deep vein thrombosis and pulmonary embolism, and prevention of venous thromboembolism after hip or knee replacement surgery.
- A specific reversal agent, idarucizumab (Praxbind), is available for emergency situations requiring rapid reversal of anticoagulation, which is a major clinical advantage over many other anticoagulants.
- Kidney function must be assessed before starting treatment and monitored at least annually, as approximately 80% of dabigatran is eliminated renally; the drug is contraindicated in patients with severe renal impairment (creatinine clearance below 30 mL/min).
- Capsules must be swallowed whole and never opened, crushed, or chewed, as breaking the capsule shell significantly increases bioavailability and the risk of serious bleeding events.
What Is Dabigatran Etexilate Laboratorios Liconsa and What Is It Used For?
Dabigatran etexilate Laboratorios Liconsa contains the active substance dabigatran etexilate, a synthetic small-molecule prodrug that belongs to the class of direct thrombin inhibitors. It is a generic formulation approved in the European Union as a bioequivalent alternative to the originator product. After oral administration, dabigatran etexilate is rapidly absorbed from the gastrointestinal tract and converted to its active form, dabigatran, through esterase-catalyzed hydrolysis in the plasma and liver. The conversion occurs independently of cytochrome P450 enzymes, which is one of the reasons why dabigatran has fewer drug interactions compared with warfarin and other vitamin K antagonists.
Dabigatran is a potent, competitive, reversible direct thrombin inhibitor. Thrombin (also known as coagulation factor IIa) occupies a central position in the coagulation cascade. It is the final serine protease in the cascade and is responsible for converting soluble fibrinogen into insoluble fibrin strands, which form the structural framework of a blood clot. Thrombin also activates several other coagulation factors (including factors V, VIII, XI, and XIII), amplifying the clotting response, and is a powerful activator of platelet aggregation. By directly binding to the active catalytic site of thrombin, dabigatran inhibits both free thrombin circulating in the blood and thrombin that is already bound to an existing fibrin clot. This dual inhibition of free and clot-bound thrombin distinguishes dabigatran from indirect anticoagulants such as heparin, which primarily inhibit free thrombin.
The predictable pharmacokinetic and pharmacodynamic profile of dabigatran is one of its most important clinical advantages. Unlike warfarin, which has highly variable dose-response relationships influenced by genetics, diet, and numerous drug interactions, dabigatran produces a consistent anticoagulant effect at fixed doses. This eliminates the need for routine coagulation monitoring (such as INR testing), which is required with warfarin therapy. After oral administration, peak plasma concentrations of dabigatran are typically reached within 0.5 to 2 hours. The drug has a plasma half-life of approximately 12 to 17 hours in patients with normal kidney function, supporting a twice-daily dosing regimen. Approximately 80% of dabigatran is eliminated unchanged through the kidneys, making renal function a critical determinant of drug exposure and a key consideration for dose selection.
Dabigatran etexilate is indicated for several important clinical conditions. The primary approved indications are as follows:
- Prevention of stroke and systemic embolism in adults with non-valvular atrial fibrillation (NVAF): Atrial fibrillation is the most common sustained cardiac arrhythmia, affecting an estimated 33 million people worldwide. In atrial fibrillation, the atria beat irregularly and often too rapidly, leading to blood stasis in the left atrial appendage and a significantly increased risk of thrombus formation and subsequent embolic stroke. The landmark RE-LY trial, published in the New England Journal of Medicine in 2009, demonstrated that dabigatran 150 mg twice daily was superior to warfarin in preventing stroke and systemic embolism, while dabigatran 110 mg twice daily was non-inferior to warfarin with significantly lower rates of major bleeding.
- Treatment and prevention of recurrence of deep vein thrombosis (DVT) and pulmonary embolism (PE): Venous thromboembolism (VTE), encompassing both DVT and PE, is the third most common cardiovascular disease globally. The RE-COVER and RE-COVER II trials demonstrated that dabigatran was non-inferior to warfarin for the treatment of acute VTE, with a comparable efficacy profile and significantly fewer bleeding events. The RE-MEDY and RE-SONATE trials further demonstrated the efficacy of dabigatran for the extended prevention of recurrent VTE.
- Prevention of venous thromboembolism following elective hip or knee replacement surgery: Major orthopaedic surgery carries a high risk of VTE due to surgical trauma, immobilization, and activation of the coagulation cascade. The RE-MODEL, RE-MOBILIZE, and RE-NOVATE trials established dabigatran as an effective and convenient oral alternative to subcutaneous enoxaparin for thromboprophylaxis after total knee and hip replacement surgery.
Unlike warfarin, dabigatran does not require regular INR monitoring, has a rapid onset of action (within 1–2 hours versus several days for warfarin), has fewer food and drug interactions, and has a specific reversal agent (idarucizumab) available for emergency situations. These advantages have made direct oral anticoagulants including dabigatran the preferred first-line anticoagulants for most indications in current international guidelines, including the 2024 ESC Guidelines for the management of atrial fibrillation.
What Should You Know Before Taking Dabigatran Etexilate?
Contraindications
Several absolute contraindications must be carefully considered before initiating dabigatran therapy. The drug must not be used in patients who have a known hypersensitivity to dabigatran etexilate or any of the excipients in the formulation. Patients with severe renal impairment, defined as a creatinine clearance (CrCl) below 30 mL/min, must not take dabigatran because the predominantly renal elimination of the drug would lead to excessive accumulation, dramatically increasing the risk of life-threatening bleeding. Dabigatran is also strictly contraindicated in patients with active clinically significant bleeding or in those with organ lesions that carry a high risk of significant bleeding, such as current or recent gastrointestinal ulceration, malignant neoplasms at high risk of bleeding, recent brain or spinal injury, recent intracranial haemorrhage, or known oesophageal varices.
A critical contraindication that is sometimes overlooked concerns mechanical prosthetic heart valves. The RE-ALIGN trial, which evaluated dabigatran in patients with mechanical heart valves, was terminated prematurely due to excess thromboembolic events (including valve thrombosis and stroke) and bleeding compared with warfarin. Therefore, dabigatran must never be used in patients with mechanical prosthetic heart valves. Patients with bioprosthetic heart valves may be considered for dabigatran therapy, but this decision should be made by a specialist. Additionally, dabigatran is contraindicated with concurrent use of systemic ketoconazole, itraconazole, ciclosporin, and dronedarone, all of which are potent inhibitors of the P-glycoprotein transporter and can markedly increase dabigatran plasma levels.
Patients with hepatic impairment who have elevated liver enzymes greater than twice the upper limit of normal, or those with liver disease expected to impact survival, should not be treated with dabigatran, as the hepatic conversion of the prodrug may be altered and the limited clinical data in this population do not allow adequate safety assessment. Furthermore, concomitant treatment with any other anticoagulant (unfractionated heparin, low-molecular-weight heparin, fondaparinux, or another direct oral anticoagulant) is generally contraindicated except during the transition period when switching between anticoagulants.
Warnings and Precautions
As with all anticoagulants, dabigatran should be used with caution in conditions that carry an increased risk of bleeding. Seek immediate medical attention if you experience signs of serious bleeding, including: prolonged or unexplained bleeding from cuts, blood in urine (pink or brown), bloody or black stools, unexpected bruising, coughing up blood, vomiting blood, persistent nosebleeds, or unusual headaches. Do not stop taking dabigatran without consulting your doctor, as abrupt discontinuation increases the risk of stroke in atrial fibrillation patients.
The most significant risk associated with dabigatran therapy is bleeding. Certain patient groups are at increased risk and require careful clinical assessment before initiating treatment. These include elderly patients (particularly those over 75 years of age), patients with moderate renal impairment (CrCl 30–50 mL/min), patients with low body weight (under 50 kg), and patients concurrently receiving antiplatelet agents (such as aspirin or clopidogrel) or non-steroidal anti-inflammatory drugs (NSAIDs). In these populations, the lower dose of dabigatran (110 mg twice daily rather than 150 mg twice daily) is generally recommended for the atrial fibrillation indication, and enhanced clinical surveillance for signs and symptoms of bleeding is essential.
Renal function assessment is mandatory before starting dabigatran. Creatinine clearance should be calculated using the Cockcroft-Gault equation, and the result should guide dose selection. During treatment, renal function should be reassessed at least once yearly, and more frequently in patients over 75 years of age, those with established renal impairment, or those in clinical situations where renal function may decline (such as dehydration, concomitant nephrotoxic medications, or acute illness). If creatinine clearance falls below 30 mL/min during treatment, dabigatran must be discontinued.
Particular caution is warranted in patients undergoing spinal or epidural anaesthesia or spinal puncture, as the use of anticoagulants in this setting carries a risk of epidural or spinal haematoma, which can result in long-term or permanent paralysis. Specific timing guidelines for the last dose of dabigatran before and after neuraxial procedures must be followed precisely, and any signs of neurological impairment (such as back pain, leg weakness, or bowel or bladder dysfunction) following such procedures should be treated as a medical emergency.
Pregnancy and Breastfeeding
Dabigatran should not be used during pregnancy unless clearly necessary and the potential benefit justifies the potential risk to the fetus. Animal studies have shown reproductive toxicity at high doses, including decreased fetal body weight and increased fetal variations. There are no adequate and well-controlled studies of dabigatran in pregnant women. All anticoagulants carry a potential risk of haemorrhagic complications during pregnancy and delivery. Women of childbearing potential should use effective contraception during treatment, and pregnancy should be avoided during dabigatran therapy.
It is not known whether dabigatran or its metabolites are excreted in human breast milk. In animal studies, dabigatran was found in the milk of lactating rats. A decision must be made whether to discontinue breastfeeding or to discontinue dabigatran therapy, taking into account the benefit of breastfeeding for the child and the benefit of therapy for the mother. Due to the lack of human data, breastfeeding is not recommended during treatment with dabigatran.
How Does Dabigatran Etexilate Interact with Other Drugs?
Unlike warfarin, which is metabolized by numerous cytochrome P450 enzymes and has hundreds of documented drug interactions, dabigatran has a relatively clean interaction profile. Dabigatran etexilate (the prodrug) is a substrate of the P-glycoprotein (P-gp) efflux transporter, and the majority of clinically relevant drug interactions involve inhibitors or inducers of this transporter. The active metabolite dabigatran is not a substrate of cytochrome P450 enzymes and is not expected to have CYP-mediated drug interactions. However, several important interactions must be recognized and managed appropriately to ensure safe and effective anticoagulation.
Major Interactions (Contraindicated)
| Interacting Drug | Mechanism | Clinical Effect | Recommendation |
|---|---|---|---|
| Ketoconazole (systemic) | Strong P-gp inhibitor | Increases dabigatran exposure by 140–150% | Contraindicated |
| Itraconazole | Strong P-gp inhibitor | Significantly increases dabigatran levels | Contraindicated |
| Ciclosporin | Strong P-gp inhibitor | Markedly increases dabigatran exposure | Contraindicated |
| Dronedarone | Moderate P-gp inhibitor | Increases dabigatran exposure by approximately 70–100% | Contraindicated |
Interactions Requiring Dose Adjustment or Caution
| Interacting Drug | Mechanism | Clinical Effect | Recommendation |
|---|---|---|---|
| Amiodarone | P-gp inhibitor | Increases dabigatran AUC by ~60% | Consider dose reduction; enhanced monitoring |
| Verapamil | P-gp inhibitor | Increases dabigatran levels (effect depends on formulation and timing) | Reduce dose; take dabigatran at least 2 hours before verapamil |
| Quinidine | P-gp inhibitor | Increases dabigatran exposure by ~50% | Consider dose reduction |
| Clarithromycin | P-gp inhibitor | May increase dabigatran levels | Clinical monitoring; consider dose adjustment |
| Rifampicin | Strong P-gp inducer | Decreases dabigatran levels by ~65% | Avoid combination |
| St. John’s Wort | P-gp inducer | May significantly reduce dabigatran levels | Avoid combination |
| Aspirin / NSAIDs | Pharmacodynamic (additive antihaemostatic effect) | Increased bleeding risk | Use with caution; assess risk-benefit |
| SSRIs / SNRIs | Pharmacodynamic (impaired platelet function) | Increased bleeding risk | Clinical monitoring for bleeding |
Proton pump inhibitors (PPIs) such as omeprazole and pantoprazole may reduce the absorption of dabigatran by approximately 20–30%, as dabigatran etexilate requires an acidic environment for optimal dissolution. However, this reduction in exposure was not associated with reduced clinical efficacy in the RE-LY trial, and no dose adjustment is recommended when PPIs are co-administered. Patients should be informed that antacids may be taken as needed, but should not be taken within 2 hours of a dabigatran dose.
It is important to note that dabigatran does not interact with common foods, including those rich in vitamin K (such as green leafy vegetables), which is a major advantage over warfarin. There are no dietary restrictions during dabigatran therapy. However, alcohol should be consumed in moderation, as excessive alcohol intake can increase the risk of gastrointestinal bleeding and may impair liver function.
What Is the Correct Dosage of Dabigatran Etexilate?
Dosing of dabigatran etexilate must be individualized based on the clinical indication, the patient's age, renal function, body weight, and concomitant medications. The 75 mg capsule strength provided by Laboratorios Liconsa is particularly relevant for dose adjustments in specific patient populations and for the post-surgical thromboprophylaxis indication. Below are the recommended dosing regimens for each approved indication.
Adults – Stroke Prevention in Atrial Fibrillation
Standard Dose
150 mg twice daily (taken as two 75 mg capsules twice daily if 150 mg capsules are unavailable). This is the recommended dose for most adults under 80 years of age with creatinine clearance above 50 mL/min.
Reduced Dose
110 mg twice daily recommended for patients aged 80 years or older, patients concomitantly receiving verapamil, and should be considered for patients aged 75–80 years with at least one additional bleeding risk factor, patients with moderate renal impairment (CrCl 30–50 mL/min), or patients with gastritis, oesophagitis, or gastro-oesophageal reflux disease.
Adults – Treatment of DVT/PE and Prevention of Recurrence
Treatment Phase
150 mg twice daily following at least 5 days of parenteral anticoagulant therapy (e.g., low-molecular-weight heparin). Duration of treatment should be individualized based on the patient’s risk of recurrence versus bleeding risk. Minimum 3 months; extended treatment for patients with recurrent VTE or ongoing risk factors.
Adults – VTE Prevention After Hip or Knee Replacement
Hip Replacement
110 mg (first dose 1–4 hours after surgery), then 220 mg once daily for 28–35 days. In patients over 75 years or with moderate renal impairment: 75 mg first dose, then 150 mg once daily.
Knee Replacement
110 mg (first dose 1–4 hours after surgery), then 220 mg once daily for 10 days. In patients over 75 years or with moderate renal impairment: 75 mg first dose, then 150 mg once daily.
Children
Dabigatran etexilate is not recommended for use in children under 18 years of age for most indications, as safety and efficacy have not been established in this population. However, a paediatric formulation of dabigatran has been evaluated for the treatment and secondary prevention of VTE in children, with dosing based on body weight using age-appropriate formulations (oral pellets or oral solution). Paediatric dosing should only be determined and supervised by a specialist paediatric haematologist. The 75 mg hard capsule formulation is generally not appropriate for paediatric dosing.
Elderly
Elderly patients represent a particularly important population for dabigatran prescribing. Patients aged 75 to 80 years should be considered for the reduced dose (110 mg twice daily for the atrial fibrillation indication) if they have additional risk factors for bleeding. For patients aged 80 years and older, the reduced dose of 110 mg twice daily is recommended as standard practice. Renal function should be monitored more frequently in elderly patients (at least every 6 months) because age-related decline in glomerular filtration rate can lead to progressive drug accumulation. Elderly patients are also more susceptible to gastrointestinal side effects and should be monitored for signs of gastrointestinal bleeding.
Missed Dose
If a dose of dabigatran is missed, it should be taken as soon as remembered, provided there are at least 6 hours remaining before the next scheduled dose. If fewer than 6 hours remain until the next dose, the missed dose should be skipped, and the regular dosing schedule should be continued with the next planned dose. Do not take a double dose to make up for a forgotten dose. It is important to maintain consistent twice-daily dosing to ensure continuous anticoagulant protection, as the relatively short half-life of dabigatran (12–17 hours) means that missed doses can leave patients temporarily under-anticoagulated and at increased risk of thromboembolic events.
Overdose
There is no specific antidote for dabigatran overdose in the outpatient setting; however, the specific reversal agent idarucizumab (Praxbind) is available in hospital settings for life-threatening or uncontrolled bleeding, or for patients requiring emergency surgery. Idarucizumab is a humanized monoclonal antibody fragment that binds to dabigatran with approximately 350 times greater affinity than thrombin, effectively neutralizing the anticoagulant effect within minutes. A single intravenous dose of 5 g completely reverses the anticoagulant effect of dabigatran in most patients.
In case of overdose, standard supportive measures should be initiated, including assessment of the patient's haemodynamic status and haemostasis. Dabigatran can be dialyzed, with haemodialysis removing approximately 60% of the drug over 2–3 hours. Activated charcoal may be considered if the overdose was recent (within 1–2 hours of ingestion). Fresh frozen plasma does not reverse the anticoagulant effect of dabigatran. Prothrombin complex concentrates (PCCs) or activated prothrombin complex concentrates (aPCCs) may be considered as adjunctive measures in emergency situations where idarucizumab is not available. Any suspected overdose should be treated as a medical emergency, and the patient should be transported to a hospital immediately.
What Are the Side Effects of Dabigatran Etexilate?
As with all anticoagulants, bleeding is the most clinically significant adverse effect of dabigatran. The risk of bleeding is influenced by patient age, renal function, body weight, concomitant medications, and the presence of other risk factors. In the RE-LY trial, dabigatran 150 mg twice daily had similar rates of major bleeding compared with warfarin, while dabigatran 110 mg twice daily had significantly lower rates of major bleeding. Importantly, both doses of dabigatran were associated with significantly lower rates of intracranial haemorrhage compared with warfarin, which is considered one of the major advantages of dabigatran therapy. However, dabigatran was associated with higher rates of gastrointestinal bleeding compared with warfarin, particularly in elderly patients.
Beyond bleeding, the most frequently reported non-haemorrhagic side effects are gastrointestinal in nature. Dabigatran etexilate capsules contain a tartaric acid core that is essential for drug absorption but can cause local irritation of the gastric mucosa. This is why dyspepsia, epigastric pain, and gastritis-like symptoms are among the most common complaints, occurring in approximately 10–15% of patients. These symptoms can often be managed by taking the capsules with food or a glass of water, and are rarely severe enough to require treatment discontinuation.

How Should You Store Dabigatran Etexilate?
Proper storage of dabigatran etexilate capsules is essential to maintain their efficacy and safety. Dabigatran etexilate is highly sensitive to moisture, and exposure to humidity can degrade the prodrug, reducing its bioavailability and potentially affecting its anticoagulant effectiveness. For this reason, the capsules must always be stored in their original packaging, whether in aluminium blister packs or in bottles with desiccant caps.
The capsules should be stored at a temperature not exceeding 30°C (86°F). They should not be removed from the original blister packaging until immediately before use. If the product is supplied in a bottle with a screw cap, the bottle must be tightly closed immediately after each use, and the capsules should be used within 4 months of first opening the bottle. Any capsules remaining after 4 months should be discarded. The desiccant cap or desiccant sachet (where provided) should never be removed, as it helps to control moisture within the packaging.
Do not use dabigatran capsules after the expiry date printed on the packaging. Do not throw away any medicines via wastewater or household waste. Ask your pharmacist how to properly dispose of unused or expired medication. These measures help to protect the environment and ensure that potent medications do not enter the wrong hands. Keep all medications out of the sight and reach of children.
What Does Dabigatran Etexilate Laboratorios Liconsa Contain?
The active substance in Dabigatran etexilate Laboratorios Liconsa is dabigatran etexilate, provided as dabigatran etexilate mesilate. Each hard capsule contains dabigatran etexilate mesilate equivalent to 75 mg of dabigatran etexilate. Dabigatran etexilate is a double prodrug: after oral absorption, it undergoes rapid hydrolysis to form the intermediate metabolite BIBR 951, which is then further hydrolyzed to the active compound dabigatran. The mesilate salt form is used to improve the stability and dissolution characteristics of the active pharmaceutical ingredient.
The capsule contents include several inactive ingredients (excipients) that play important roles in the formulation. Tartaric acid is a critical excipient in the dabigatran capsule core, as it creates a local acidic microenvironment around the pellets upon contact with gastrointestinal fluid. This is necessary because dabigatran etexilate has pH-dependent solubility and requires an acidic pH for optimal dissolution and absorption. Other excipients typically include acacia (gum arabic) as a binder, hypromellose as a capsule shell material, dimethicone as an antifoaming agent, talc as a glidant, and hydroxypropylcellulose as an additional binder. The capsule shell itself is composed of hypromellose (HPMC) and may contain colourants such as titanium dioxide (E171) and indigo carmine (E132), along with yellow iron oxide (E172) and other colouring agents depending on the capsule strength.
It is important to note that the capsule formulation is specifically designed to protect the dabigatran etexilate pellets from moisture and to deliver the drug in a controlled manner. This is why patients must never open, chew, or break the capsules before swallowing. Doing so would destroy the pellet coating, expose the drug to an altered pH environment, and dramatically increase its bioavailability, which could lead to dangerously high plasma levels and a significantly increased risk of bleeding.
Frequently Asked Questions About Dabigatran Etexilate
Dabigatran etexilate is a direct oral anticoagulant (DOAC) used to prevent stroke and systemic embolism in adults with non-valvular atrial fibrillation, to treat and prevent recurrence of deep vein thrombosis (DVT) and pulmonary embolism (PE), and to prevent venous thromboembolism after elective hip or knee replacement surgery. It works by directly inhibiting thrombin, a key enzyme in the blood clotting cascade.
Dabigatran capsules should be swallowed whole with a full glass of water, with or without food. Do not open, chew, or break the capsules, as this can significantly increase drug absorption and raise the risk of bleeding. The capsules are usually taken twice daily at approximately the same time each day. Always follow your doctor's specific dosing instructions.
Yes, idarucizumab (marketed as Praxbind) is a specific reversal agent for dabigatran. It is a monoclonal antibody fragment that binds to dabigatran with very high affinity, neutralizing its anticoagulant effect within minutes. Idarucizumab is approved for emergency situations such as life-threatening bleeding or when urgent surgery is required. This specific reversal agent is a significant advantage of dabigatran over some other anticoagulants.
Unlike warfarin, dabigatran does not require routine coagulation monitoring (INR checks). However, your doctor will check your kidney function (creatinine clearance) before starting treatment and at least once a year during treatment, since dabigatran is primarily eliminated through the kidneys. More frequent monitoring may be needed for elderly patients or those with reduced kidney function.
Yes, dabigatran capsules can be taken with or without food. Unlike warfarin, there are no dietary restrictions with dabigatran — foods rich in vitamin K (such as green leafy vegetables) do not affect its efficacy. Taking the capsules with food may help reduce gastrointestinal side effects such as dyspepsia and stomach pain, which are among the most common complaints with dabigatran therapy.
If you miss a dose, take it as soon as you remember, provided there are at least 6 hours until your next scheduled dose. If fewer than 6 hours remain, skip the missed dose and take the next one at the usual time. Never take a double dose to compensate for a missed one. Contact your doctor if you have missed several doses, as you may be at increased risk of blood clots during periods without anticoagulation.
