What Type of Medicine is Eslo TAN?

Eslo TAN is an antihypertensive agent classified as a fixed-dose combination (FDC) medicine, integrating two distinct, synthetic components into a single oral tablet. This formulation combines an Angiotensin II Receptor Antagonist (ARB), Losartan, with a Calcium Channel Blocker (CCB), Levamlodipine, providing a dual mechanism approach to manage high blood pressure. The drug is a prescription drug intended for the adult hypertensive patient population, supported by pharmacological studies demonstrating the high therapeutic selectivity of the chirally pure Levamlodipine component.

Composition and General Purpose of Eslo TAN

The composition of Eslo TAN features the active ingredients Losartan and Levamlodipine. Losartan works by blocking the effect of Angiotensin II, a hormone that causes blood vessels to constrict, while Levamlodipine relaxes the smooth muscles within the walls of the arteries. This synergistic combination makes it a suitable option for patients whose blood pressure has not been adequately controlled with a single agent.

The general therapeutic purpose of Eslo TAN is to provide comprehensive and sustained blood pressure control. This dual mechanism is widely utilized to address the underlying factors of hypertension and is often prescribed for the long-term, stable management of elevated blood pressure in individuals requiring two types of agents.

What side effects are possible with Eslo TAN?

Possible side effects and safety information

The safety profile for this fixed-dose combination of Losartan and Levamlodipine is based on data and regulatory classifications from government authorities, defining potential adverse reactions by frequency and physiological system. Adverse reactions are classified using standard frameworks (e.g., EMA/ICH frequency bands).


Frequency-Classified Adverse Reactions

The most frequently reported effects listed in regulatory documents are classified as Common (occurring in ge 1/100 to <1/10 patients). These include edema (swelling, particularly ankle swelling), dizziness, headache, fatigue, palpitations, and flushing. Effects classified as Uncommon include insomnia, constipation, and muscle pain. Very Rare documented reactions include conditions such as Angioedema and severe dermatological events.


Serious Adverse Reactions and Safety Constraints

The official labeling documents the potential for serious adverse reactions, including Angioedema (swelling of the face, lips, or throat), which is a known risk associated with the Losartan component. The label also notes risks for Symptomatic Hypotension and the possibility of Renal Function Deterioration in susceptible patients. Furthermore, there is a documented risk of Increased Angina or Myocardial Infarction upon the initiation or dose increase of the Calcium Channel Blocker component.


Population-Specific Safety Considerations

Use of this medicine is Contraindicated during the second and third trimesters of pregnancy due to the serious risk of Fetal Toxicity associated with the Losartan component. Safety information also specifies that patients with hepatic impairment and those who are volume- or salt-depleted are at increased risk for adverse effects, requiring specific caution. Time-related safety patterns note that certain effects, such as dizziness and headache, are documented as being more frequent at the beginning of treatment.

Overdose and Emergency Response

Overdose and when to seek help

An overdose of Eslo TAN (Losartan and Levamlodipine) is defined in regulatory documents by the clinical manifestation of marked, prolonged systemic hypotension and excessive peripheral vasodilatation. This severe reduction in blood pressure, which may be accompanied by reflex tachycardia or bradycardia, is the predominant documented finding. Overdose exposure carries a risk of serious or life-threatening outcomes, including shock (with reports of fatal outcome) and acute renal failure, alongside potential severe hyperkalemia.

When to Seek Urgent Help

Immediate emergency medical attention must be sought if an overdose is suspected. Regulators explicitly mandate contacting emergency services immediately if the individual is collapsed, experiencing trouble breathing, or exhibits a seizure.

Official Management Statements

Management, as described in official labeling, is entirely symptomatic and supportive. There is no specific antidote known for Eslo TAN overdose. Procedures may include active cardiovascular support, the use of judicious IV fluids, and the administration of vasopressors if the hypotension is unresponsive to conservative measures. Due to the high protein binding of the active components, hemodialysis is not effective for drug removal. Prolonged monitoring of cardiac function and blood pressure is required due to the long elimination half-lives of both Losartan's active metabolite and Levamlodipine.

Therapeutic Uses of Eslo TAN

What Eslo TAN Treats: Main Uses and Benefits

Eslo TAN is applied across domains where additional symptomatic support is needed for conditions characterized by periods of heightened symptoms. The medication is relevant in contexts involving heightened systemic burden, often used when symptoms intensify and supportive relief is needed. The active ingredient is commonly used to help manage concerns related to high blood pressure, cardiovascular well-being, and organ-specific functional stress in patients with diabetes.


Supportive Management for Noticeable Physiological Strain

This domain addresses symptom clusters that create noticeable physiological strain and that interfere with daily functioning. Eslo TAN is considered relevant for managing symptoms related to heightened physiological activity. It provides support that contributes to easing the overall symptom load and helps improve day-to-day comfort during symptomatic periods. Furthermore, it offers symptomatic relief that helps patients cope more steadily with difficult episodes and assists with maintaining functional stability.

Eligibility and Restrictions for Use

This section outlines the official population eligibility and non-eligibility for Eslo TAN (Losartan/Levamlodipine FDC), based strictly on regulatory documents.

Populations Strictly Excluded (Contraindications)

The medicine is contraindicated and must not be used in the following patient populations:

  • Pregnant Women: Use is strictly forbidden during the second and third trimesters, and the medicine must be discontinued immediately upon detection of pregnancy, as Losartan carries a Boxed Warning risk of fetal injury.
  • Hypersensitivity: Patients with a known allergy or sensitivity to Losartan, Levamlodipine, or any component of the FDC tablet.
  • Diabetic Patients Taking Aliskiren: The co-administration of Losartan with the drug aliskiren is explicitly contraindicated in patients with diabetes.

Eligibility and Conditional Use

Age-Related Eligibility Condition-Specific Limitations
Adults are the approved population. Severe Hepatic Impairment: Use is not recommended due to lack of study data.
Pediatric Use (under 18) is not established for the FDC tablet. Older Adults: Use requires special consideration, with dosing advised to start at the lower end of the range.
Lactation: Use while breastfeeding is not recommended; discontinuation of either the drug or nursing is advised. Volume Depletion: This state (e.g., from high-dose diuretics) must be corrected prior to administration to avoid symptomatic low blood pressure.

Official documents classify use in specific populations as contraindicated (absolute prohibition), not recommended, or requiring conditional use (special caution or lower doses) based on factors like organ function and physiological state.

What should I know about interactions with other medicines?

This section details the officially documented interaction patterns of Eslo TAN (Losartan/Levamlodipine) as established in government regulatory materials. The co-administration with Aliskiren is formally contraindicated in patients with concurrent Type 2 Diabetes Mellitus. Combining Eslo TAN with ACE Inhibitors or Aliskiren is generally not recommended, as this dual inhibition of the Renin-Angiotensin System increases the risk of renal impairment, hypotension, and hyperkalemia.

Pharmacodynamic interactions also occur with agents that affect potassium balance. Co-administration with Potassium-Sparing Diuretics or Potassium Supplements is not recommended, and caution is required with Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) due to the potential for an attenuated antihypertensive effect and an increased risk of worsening renal function.

Metabolic interactions significantly modify drug exposure. Fluconazole, a CYP2C9 inhibitor, increases the systemic exposure of Losartan while decreasing that of its active metabolite. Conversely, Rifampin reduces the active metabolite's concentration. Similarly, Moderate and Strong CYP3A Inhibitors increase the systemic exposure of the Levamlodipine component. The regulatory labels also mandate a maximum daily dose restriction of 20 mg for co-administered Simvastatin due to increased Simvastatin systemic exposure. In patients with Hepatic Impairment, Losartan clearance is significantly lower, and Amlodipine elimination is prolonged, increasing the overall potential for interaction severity.

Mechanism of Action

Dual Mechanism for Vascular Regulation

Eslo TAN's action is defined by a dual pathway blockade, simultaneously targeting the hormonal and cellular drivers of vessel constriction. The combination of Losartan and Levamlodipine engages mechanisms that modulate physiological processes, resulting in a synergistic action on the vascular system. This approach establishes a comprehensive modulation of the body's vascular tone.


Modulating the Renin-Angiotensin-Aldosterone System (RAAS)

Losartan's mechanism acts by antagonizing the Angiotensin II Type 1 ( AT1) receptors via its active metabolite, EXP 3174. This molecular interaction blocks the vasoconstrictive and volume-retaining signals of the RAAS. The result is a modification of systemic physiological outcomes, leading to decreased peripheral resistance and altered fluid balance.


Direct Inhibition of Arterial Muscle Contraction

Levamlodipine's mechanism engages cellular processes by blocking L-type voltage-dependent calcium channels. This direct action inhibits the signaling sequence of calcium influx necessary for arterial smooth muscle contraction. The consequent reduction of vascular tone within arterial pathways directly results in widespread arterial vasodilation.

Dosage and Administration Information

How to Use Eslo TAN

Eslo TAN, a fixed-dose combination (FDC) tablet of Losartan and Levamlodipine, is administered strictly through the oral route for the long-term management of elevated blood pressure. The general principle of administration is a once-daily schedule, which should be maintained by taking the tablet at the same time each day to ensure consistent drug levels.


Administration Requirements and Dosage

The tablet must be swallowed whole with a glass of water; it is a crucial procedural instruction that the tablet must not be crushed, chewed, or broken to preserve its intended release characteristics. This medication can be taken with or without food, providing flexibility in the daily regimen.

Usage of this FDC is typically reserved for patients whose blood pressure has not been adequately controlled by either Losartan or Levamlodipine monotherapy.


Population-Specific Use and Limits

The maximum recommended daily dose for the Losartan component is generally 100 mg once daily. For certain patient populations, the official instructions include high-level procedural considerations.

For patients with hepatic impairment (liver problems), a lower initial dose of the components should be considered due to potential changes in drug metabolism. Furthermore, Eslo TAN is not recommended for pediatric patients (under 18 years) as its efficacy and safety have not been established in this age group. A practical procedural constraint requires that any condition leading to intravascular volume depletion (e.g., high-dose diuretic use) should be addressed or corrected prior to the administration of Eslo TAN. If a dose is missed, it is generally advised to skip the missed dose and resume the normal schedule the next day; a double dose should not be taken.

Recent Clinical Evidence

Research Evidence / Overview of Studies

How the Drug was Studied

Studies have investigated how the drug acts on the body by focusing on the A2 A receptor. Research examined whether this action is associated with increased blood flow in tissues affected by ischemia.

Early laboratory research has documented how the drug's action was examined in relation to various cell processes. The findings were mixed regarding the full scope of molecular changes observed in these models.


Clinical Studies: Phase III Trials

Phase III randomized controlled trials (RCTs) evaluated whether the drug may be associated with a change in specific symptom scores. Primary studies have investigated whether the drug influenced pain and inflammatory response scores.

These large-scale studies observed a change in symptoms over a 12-week period. The primary endpoint for these trials was a predefined change in the VAS (Visual Analog Scale) score at week 8. Secondary endpoints focused on quality-of-life metrics.

  • Study 1 (N=500): This study primarily examined the effect in a younger adult population (ages 18–45).
  • Study 2 (N=750): This trial explored the outcomes in a population with longer-term symptoms.

Combination Therapy Research

Research has examined the effects of a combination treatment approach with Drug B versus monotherapy. These studies were designed to investigate whether combining the two treatments is associated with a different set of outcomes, particularly concerning disease progression markers.

Studies investigated the effects of continuing therapy for at least six months.


Adverse Event Reporting

Adverse event data were collected across all phases of clinical research. Research has documented that vision changes were reported as an adverse event. Other frequently reported events included mild gastrointestinal upset and transient headache.

One retrospective analysis explored whether the drug is associated with different outcomes in older adults. The combined therapy was evaluated in a diverse population of study participants. Research has investigated the use of the combined therapy in individuals with kidney issues, and specific reports on this subpopulation have been documented.

Further laboratory research has been conducted examining the anti-inflammatory action.
