== Pharmacological Mechanisms & Scientific Evidence == | |||
=== Cardioprotective & Anti-Ischemic Actions === | |||
''T. arjuna'' extracts preserve myocardial structural integrity during ischemic events and reperfusion injury<ref name="Dwivedi2014"/>: | |||
* '''Endogenous Antioxidant Preservation:''' Prevents the depletion of key intracellular antioxidant enzymes, including superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx)<ref name="Pauzi2021"/>. | |||
* '''Anti-Apoptotic Regulation:''' Downregulates pro-apoptotic markers (Bax, caspase-3) while upregulating anti-apoptotic proteins ([[Bcl-2]]) and heat shock proteins (HSP-70) in ischemic cardiomyocytes<ref name="Mould2023"/>. | |||
A double-blind, randomized, placebo-controlled crossover study evaluated 58 patients with chronic stable angina (NYHA Class II–III). Administration of 500 mg of ''T. arjuna'' bark extract every 8 hours significantly reduced anginal frequency and nitrate consumption, accompanied by objective improvements in treadmill exercise duration and reduced peak ST-segment depression compared to placebo<ref name="Bharani2002">{{cite journal |last1=Bharani |first1=A. |last2=Ganguly |first2=A. |last3=Bhargava |first3=K.

Furthermore, clinical evaluations in congestive heart failure and ischemic heart disease demonstrate improved left ventricular ejection fraction<ref name="Vaidya2010">{{cite journal |last1=Vaidya |first1=A.

=== Vascular Tone & Anti-Hypertensive Efficacy === | |||
* '''Endothelial Nitric Oxide Activation:''' Flavonoid and glycoside fractions stimulate endothelial nitric oxide synthase (eNOS), increasing vascular [[Nitric oxide|NO]] availability and inducing endothelium-dependent vasodilation<ref name="Mould2023"/>. | |||
* '''Inotropic & Chronotropic Balance:''' Demonstrates positive inotropic (enhancing force of contraction) and mild negative chronotropic (regulating pulse rate) effects without increasing myocardial oxygen demand<ref name="Dwivedi2014"/>. | |||
=== Anti-Platelet & Anti-Atherosclerotic Effects === | |||
* '''Thrombin-Induced Inhibition:''' The isolated triterpenoid '''arjunolic acid''' inhibits thrombin-induced platelet aggregation with an <math>IC_{50}</math> of 0.048 mM—exhibiting greater potency than aspirin (<math>IC_{50} = 0.088\text{ mM}</math>)<ref name="Sinha2008"/><ref name="Pauzi2021"/>. | |||
* '''Lipid Modulation & Foam Cell Suppression:''' Reduces circulating total cholesterol, low-density lipoprotein (LDL), and triglycerides while raising high-density lipoprotein (HDL) via upregulation of PPAR-γ pathways and suppression of oxidative LDL modification<ref name="Dwivedi2014"/>. | |||
== Posology & Preparations == | |||
{| class="wikitable" | |||

|- | |||
| '''Standardized Dry Extract''' (Capsule/Tablet) || 250–500 mg twice or thrice daily || Ischemic heart disease, coronary artery disease prophylaxis. | |||
|} | |} | ||
== Safety, Toxicology & Contraindications == | |||
* '''Toxicological Profile:''' Preclinical safety evaluations demonstrate high oral safety thresholds (<math>LD_{50} > 2000\text{ mg/kg}</math> in rodent models)<ref name="Mould2023"/>. Clinical studies confirm excellent tolerability across long-term administration<ref name="Bharani2002"/>. | |||
* '''Adverse Reactions:''' Mild, transient gastrointestinal effects (such as mild constipation or dyspepsia) may occur due to the high tannin concentration. | |||
* '''Precautions & Interactions:''' | |||
** '''Anticoagulants & Antiplatelets:''' Given arjunolic acid's inhibitory effect on thrombin-induced aggregation, monitor coagulation metrics when co-prescribed with agents like Warfarin, Aspirin, or Clopidogrel<ref name="Sinha2008"/>. | |||
** '''Antihypertensives:''' Potential additive hypotensive effects; routine blood pressure monitoring is advised when integrated into existing antihypertensive regimens<ref name="Dwivedi2014"/>. | |||
