Saroglitazar and Ayurveda – A Holistic Approach to Metabolic Health

Abstract

Metabolic disorders such as dyslipidemia, insulin resistance, type 2 diabetes mellitus, obesity, and metabolic dysfunction-associated steatotic liver disease (MASLD) have become increasingly prevalent worldwide. These conditions are interconnected and often arise from disturbances in lipid metabolism, glucose regulation, chronic inflammation, and oxidative stress. Saroglitazar is a novel dual peroxisome proliferator-activated receptor (PPAR) agonist that has gained attention for its ability to improve both lipid and glycemic parameters. By targeting PPAR-α and PPAR-γ receptors, it helps regulate triglyceride levels, insulin sensitivity, and hepatic metabolism. While Saroglitazar has shown promising clinical benefits, there is growing interest in natural approaches that support similar metabolic pathways. Ayurveda describes numerous medicinal plants traditionally used to manage disorders associated with impaired metabolism, excessive fat accumulation, and disturbed glucose homeostasis. Modern scientific research has validated many of these herbs and revealed mechanisms involving PPAR modulation, AMP-activated protein kinase (AMPK) activation, antioxidant activity, anti-inflammatory effects, and hepatoprotection. This article explores the pharmacological profile of Saroglitazar and discusses Ayurvedic herbs that may support metabolic health through complementary biological pathways.

Introduction

Metabolic diseases represent one of the greatest health challenges of the modern era. Rapid urbanization, sedentary lifestyles, excessive consumption of processed foods, chronic stress, and inadequate physical activity have significantly contributed to the rising incidence of obesity, diabetes, dyslipidemia, and fatty liver disease. These disorders rarely exist in isolation. Instead, they are often interconnected through complex metabolic disturbances involving insulin resistance, chronic inflammation, lipid abnormalities, and oxidative stress. The development of newer pharmacological agents has improved the management of these conditions. Saroglitazar is one such advancement that has attracted considerable interest because of its ability to simultaneously target lipid and glucose metabolism. However, long-term metabolic health requires a broader approach that includes dietary modifications, lifestyle interventions, and supportive therapies. Ayurveda has long emphasized the importance of maintaining healthy metabolism through balanced digestion (Agni), proper tissue nourishment, and prevention of metabolic toxin accumulation (Ama). Interestingly, many Ayurvedic herbs traditionally used for metabolic disorders have demonstrated scientifically validated effects on pathways now recognized as central to modern metabolic medicine. Understanding these connections provides valuable insight into how traditional herbal medicine and contemporary scientific knowledge may complement one another.

What is Saroglitazar?

• Saroglitazar is an oral medication classified as a dual PPAR agonist. It was specifically developed to address abnormalities in both lipid and glucose metabolism, making it particularly useful in patients with diabetic dyslipidemia and elevated triglyceride levels.
• Unlike conventional lipid-lowering drugs that primarily target cholesterol metabolism, Saroglitazar exerts broader metabolic effects through activation of nuclear receptors involved in energy regulation. This unique mechanism allows it to influence multiple aspects of metabolic health simultaneously.

Saroglitazar is commonly prescribed for

1. Hypertriglyceridemia
2. Diabetic dyslipidemia
3. Type 2 diabetes associated with abnormal lipid levels
4. Metabolic dysfunction-associated steatotic liver disease (MASLD)
5. Conditions associated with insulin resistance

Its therapeutic value stems from its ability to improve triglyceride metabolism while simultaneously enhancing insulin sensitivity.

The Science Behind PPAR Receptors

• To understand how Saroglitazar works, it is important to understand the role of PPARs (Peroxisome Proliferator-Activated Receptors).
• PPARs are nuclear transcription factors that regulate the expression of genes involved in energy metabolism. They act as metabolic sensors and influence how the body processes fats, sugars, and inflammatory signals.

PPAR-Alpha: The Fat-Burning Regulator

• PPAR-α is highly expressed in tissues that actively metabolize fats, particularly the liver, heart, kidneys, and skeletal muscles.
• When activated, PPAR-α stimulates the expression of genes involved in fatty acid oxidation. As a result, the body becomes more efficient at utilizing stored fats for energy rather than allowing them to accumulate within tissues.

Activation of PPAR-α leads to

1. Increased breakdown of fatty acids
2. Reduction in triglyceride levels
3. Decreased production of very-low-density lipoproteins (VLDL)
4. Improved lipid utilization
5. Reduction in hepatic fat accumulation

These actions are particularly beneficial for individuals with hypertriglyceridemia and fatty liver disease.

PPAR-Gamma: The Insulin Sensitivity Regulator

• PPAR-γ is primarily found in adipose tissue and plays a crucial role in glucose metabolism.
• Activation of this receptor enhances insulin responsiveness by promoting glucose uptake into cells and improving insulin signaling pathways. This reduces insulin resistance, a central feature of type 2 diabetes and metabolic syndrome.

Key Effects include

1. Improved glucose utilization
2. Enhanced insulin sensitivity
3. Better regulation of adipokines
4. Reduced metabolic inflammation

Through simultaneous activation of both receptors, Saroglitazar addresses multiple metabolic abnormalities that frequently coexist.

Mechanism of Action of Saroglitazar

Saroglitazar exerts its therapeutic effects through dual activation of Peroxisome Proliferator-Activated Receptor Alpha (PPAR-α) and Peroxisome Proliferator-Activated Receptor Gamma (PPAR-γ), two ligand-activated nuclear receptors that regulate genes involved in lipid metabolism, glucose homeostasis, inflammation, and energy balance. After entering the cell, Saroglitazar binds to these receptors in the nucleus. The activated receptor subsequently forms a heterodimer with the Retinoid X Receptor (RXR). This PPAR-RXR complex then binds to specific DNA sequences known as Peroxisome Proliferator Response Elements (PPREs) located within the promoter regions of target genes. Through this interaction, Saroglitazar alters the transcription of numerous genes involved in fatty acid oxidation, triglyceride metabolism, insulin signaling, adipokine production, and inflammatory responses. The resulting changes in gene expression account for its broad metabolic benefits.

1. Improvement of Lipid Metabolism

• One of the most important actions of Saroglitazar is its effect on lipid metabolism, primarily mediated through activation of PPAR-α. This receptor is highly expressed in tissues that actively metabolize fatty acids, including the liver, skeletal muscles, heart, and kidneys. Upon activation, PPAR-α increases the expression of genes responsible for fatty acid transport and β-oxidation. Proteins such as Fatty Acid Transport Protein (FATP), CD36, and Fatty Acid Binding Proteins (FABPs) facilitate the uptake and intracellular transport of fatty acids. Simultaneously, Saroglitazar enhances the expression of enzymes involved in mitochondrial and peroxisomal β-oxidation, including Carnitine Palmitoyltransferase-1 (CPT-1), Acyl-CoA Oxidase (ACOX1), and various acyl-CoA dehydrogenases. CPT-1 plays a particularly crucial role by transporting long-chain fatty acids into mitochondria, where they undergo oxidation to generate energy. As fatty acid oxidation increases, the availability of free fatty acids for triglyceride synthesis decreases, leading to lower hepatic triglyceride production.
• In addition to promoting fat utilization, Saroglitazar suppresses lipogenic pathways responsible for the formation of new fatty acids. Activation of PPAR-α downregulates transcription factors such as Sterol Regulatory Element-Binding Protein-1c (SREBP-1c) and enzymes including Fatty Acid Synthase (FAS) and Acetyl-CoA Carboxylase (ACC). These molecules are essential for de novo lipogenesis, the process through which excess carbohydrates are converted into fatty acids. By inhibiting these pathways, Saroglitazar reduces hepatic triglyceride accumulation and helps prevent excessive fat deposition in the liver. Furthermore, it increases the activity of Lipoprotein Lipase (LPL) while reducing levels of Apolipoprotein C-III (ApoC-III), an inhibitor of LPL. Enhanced LPL activity accelerates the breakdown of triglyceride-rich lipoproteins such as very-low-density lipoproteins (VLDL) and chylomicrons, contributing to significant reductions in circulating triglyceride levels.

2. Enhancement of Insulin Sensitivity

• Saroglitazar’s moderate activation of PPAR-γ contributes to improvements in glucose metabolism and insulin sensitivity. PPAR-γ is predominantly expressed in adipose tissue and serves as a key regulator of adipocyte differentiation, insulin signaling, and glucose utilization. Activation of this receptor increases the transcription of genes involved in glucose transport, particularly Glucose Transporter Type-4 (GLUT-4). GLUT-4 is responsible for insulin-dependent glucose uptake into skeletal muscle and adipose tissue. Increased GLUT-4 expression enhances the ability of cells to remove glucose from the bloodstream, thereby improving glycemic control.
• Another important consequence of PPAR-γ activation is increased production of adiponectin, an adipose-derived hormone with potent insulin-sensitizing properties. Adiponectin activates AMP-Activated Protein Kinase (AMPK), a critical cellular energy sensor that promotes fatty acid oxidation and glucose uptake while suppressing hepatic glucose production. Through activation of AMPK, adiponectin enhances insulin responsiveness in multiple tissues. Saroglitazar also reduces lipotoxicity, a condition in which excess fatty acids accumulate within liver cells, skeletal muscles, and pancreatic beta cells. Lipid accumulation within these tissues disrupts insulin signaling pathways and contributes to insulin resistance. By promoting fatty acid oxidation and reducing intracellular lipid burden, Saroglitazar helps restore normal insulin signaling.
• At the molecular level, improvements in insulin sensitivity are associated with enhanced activity of the Insulin Receptor Substrate (IRS)-1, Phosphatidylinositol 3-Kinase (PI3K), and Akt (Protein Kinase B) signaling pathway. These signaling molecules play central roles in mediating insulin action. Improved activation of the IRS-1/PI3K/Akt pathway promotes glucose transport, glycogen synthesis, and overall metabolic efficiency, thereby reducing insulin resistance.

3. Reduction of Inflammatory Activity

• Chronic low-grade inflammation is now recognized as a fundamental driver of metabolic syndrome, insulin resistance, type 2 diabetes, and fatty liver disease. Excess adipose tissue releases inflammatory cytokines that interfere with insulin signaling and contribute to tissue damage. Saroglitazar helps counteract this process through both PPAR-α and PPAR-γ activation. One of the most significant mechanisms involves inhibition of Nuclear Factor-kappa B (NF-κB), a transcription factor that regulates the expression of numerous inflammatory genes. Activated PPARs interfere with NF-κB signaling, reducing its ability to promote the production of inflammatory mediators.
• As a result, levels of cytokines such as Tumor Necrosis Factor-Alpha (TNF-α), Interleukin-6 (IL-6), and Interleukin-1β (IL-1β) are reduced. These cytokines are known to impair insulin signaling and contribute to metabolic dysfunction. Saroglitazar also influences immune cell behavior by promoting a shift in macrophage polarization from the pro-inflammatory M1 phenotype toward the anti-inflammatory M2 phenotype. This transition reduces tissue inflammation and creates a more favorable metabolic environment. Additionally, improved fatty acid metabolism reduces the generation of reactive oxygen species and lipid peroxidation products, thereby lowering oxidative stress and further suppressing inflammatory responses.

4. Support for Liver Health

• The liver is a central organ in lipid and glucose metabolism and is one of the primary targets of Saroglitazar. Excessive accumulation of triglycerides within hepatocytes contributes to the development of metabolic dysfunction-associated steatotic liver disease (MASLD) and can progress to steatohepatitis and fibrosis. Saroglitazar addresses several mechanisms responsible for hepatic fat accumulation. Through activation of PPAR-α, it enhances hepatic fatty acid oxidation by increasing the expression of CPT-1, ACOX1, and other enzymes involved in β-oxidation. This promotes the utilization of stored hepatic fat as an energy source.
• At the same time, Saroglitazar suppresses transcription factors such as SREBP-1c and Carbohydrate Response Element-Binding Protein (ChREBP), both of which stimulate fatty acid synthesis. Reduced activity of these transcription factors decreases hepatic lipogenesis and limits the formation of new triglycerides. Enhanced insulin sensitivity also contributes to reduced hepatic fat accumulation by suppressing excessive gluconeogenesis and decreasing the conversion of carbohydrates into fatty acids.
• The anti-inflammatory properties of Saroglitazar further support liver health. Chronic hepatic inflammation plays a key role in the progression from simple steatosis to steatohepatitis and fibrosis. By reducing inflammatory cytokines, oxidative stress, and lipid-induced cellular injury, Saroglitazar helps protect hepatocytes from damage. Improved adiponectin signaling additionally activates AMPK pathways within the liver, promoting fatty acid oxidation and reducing inflammatory responses. These combined effects contribute to reductions in liver fat content, improvements in liver enzyme levels, and better overall hepatic function.

5. Influence on Oxidative Stress

Emerging evidence suggests that Saroglitazar may also indirectly reduce oxidative stress, which is an important contributor to metabolic and hepatic injury. Excessive lipid accumulation within tissues promotes mitochondrial dysfunction and generation of reactive oxygen species (ROS). By enhancing fatty acid oxidation and reducing lipid overload, Saroglitazar decreases ROS production and limits oxidative damage to cellular proteins, lipids, and DNA. Reduced oxidative stress not only protects hepatocytes but also improves endothelial function and may help prevent progression of metabolic complications. Thus, the antioxidant effects of Saroglitazar complement its lipid-lowering, insulin-sensitizing, and anti-inflammatory actions, making it a multifaceted therapeutic agent for metabolic disorders.

Ayurvedic Perspective on Metabolic Disorders

• Ayurveda views metabolic diseases through a broader physiological lens. Conditions involving obesity, diabetes, dyslipidemia, and fatty liver disease are often associated with disturbances in Agni (digestive and metabolic fire), accumulation of Ama (metabolic toxins), aggravation of Kapha Dosha, and dysfunction of Meda Dhatu (adipose tissue).
• According to Ayurvedic principles, impaired digestion leads to incomplete metabolism and accumulation of unwanted metabolic byproducts. Over time, these disturbances obstruct physiological channels (Srotas), disrupt tissue function, and contribute to disease development.

Management therefore focuses on

1. Improving metabolic efficiency
2. Enhancing digestive function
3. Supporting liver health
4. Reducing excess fat accumulation
5. Restoring tissue balance
6. Correcting underlying metabolic disturbances

Interestingly, modern research has identified several Ayurvedic herbs capable of influencing many of the same pathways targeted by Saroglitazar.
