Mechanism of action

Tribulus terrestris is thought to exert its effects primarily by increasing the levels of luteinizing hormone (LH) and testosterone. The saponins present in the plant may stimulate the secretion of hormones from the pituitary gland, leading to enhanced testosterone production in the testes. This increase in testosterone may contribute to improved libido and physical performance.

Pharmacodynamics

The pharmacodynamic effects of Tribulus terrestris include modulation of hormone levels, particularly testosterone and luteinizing hormone. It may enhance libido, improve mood, and potentially support muscle mass and strength when used in conjunction with exercise. The exact dose-response relationship and the full scope of its effects on human physiology require further investigation.

Pharmacokinetics

The pharmacokinetics of Tribulus terrestris, including absorption, distribution, metabolism, and excretion, are not well characterized in clinical studies. However, it is generally believed that the saponins and other active compounds are readily absorbed in the gastrointestinal tract. The half-life and elimination pathways are not well defined, necessitating further research to clarify these aspects.

Indications

• Low libido
• Erectile dysfunction
• Athletic performance enhancement
• Menstrual disorders

Dosage

Children: Refer to the BNF for Children for specific dosing information.

Adults: Refer to the BNF for specific dosing information.

Mechanism of action

Tribulus is thought to act through several mechanisms, primarily by increasing the levels of testosterone and other androgens in the body. This may occur through the stimulation of luteinizing hormone (LH) production, which in turn promotes testosterone synthesis in the Leydig cells of the testes. Additionally, its saponins may exert a mild diuretic effect and enhance nitric oxide production, leading to improved blood flow and muscle performance.

Pharmacodynamics

The pharmacodynamics of Tribulus involves its interaction with androgen receptors and the hypothalamic-pituitary-gonadal axis. The increase in testosterone levels can lead to improved libido, increased muscle mass, and enhanced physical performance. The diuretic effect may contribute to weight loss and improved body composition, although these claims require further clinical validation.

Pharmacokinetics

The pharmacokinetics of Tribulus is not thoroughly documented in the literature. However, it is believed that the active compounds are absorbed in the gastrointestinal tract, with bioavailability potentially affected by factors such as formulation and dosage. The metabolism of steroidal saponins likely involves hepatic pathways, and elimination is presumed to occur via renal excretion, although specific studies are lacking.

Mechanism of action

The exact mechanism of action of Yavakshar is not well-documented in scientific literature. However, it is thought to exert its effects primarily through its fiber content, which can enhance bowel motility and promote the excretion of waste. Additionally, its diuretic properties may stem from its ability to increase urine output and support kidney function. The soluble fiber in Yavakshar may also aid in regulating blood sugar levels and cholesterol.

Pharmacodynamics

Yavakshar is rich in dietary fiber, which can improve gastrointestinal function by adding bulk to the stool and promoting regular bowel movements. The diuretic effect may assist in reducing water retention and promoting urinary tract health. The cooling properties attributed to Yavakshar may help alleviate symptoms of heat in the body, contributing to its traditional use in managing inflammatory conditions.

Pharmacokinetics

As a natural herbal product, Yavakshar does not undergo extensive pharmacokinetic studies like conventional drugs. Its active components, mainly dietary fibers, are not significantly absorbed in the gastrointestinal tract but rather function within the gut lumen. The fibers are fermented by gut bacteria, producing short-chain fatty acids that may have systemic health benefits. The diuretic effect is primarily localized to the kidneys, enhancing fluid excretion without systemic absorption.

Pregnancy

There is limited data on the safety of yavakshar during pregnancy. It is advisable to consult a healthcare provider before use.

Breast-feeding

There is insufficient information on the excretion of yavakshar in human milk. Caution is recommended.

Storage

Store in a cool, dry place away from direct sunlight. Keep out of reach of children.

Mechanism of action

Ethanol affects the brain’s neurons in several ways. It alters their membranes as well as their ion channels, enzymes, and receptors. Alcohol also binds directly to the receptors for acetylcholine, serotonin, GABA, and the NMDA receptors for glutamate. The sedative effects of ethanol are mediated through binding to GABA receptors and glycine receptors (alpha 1 and alpha 2 subunits). It also inhibits NMDA receptor functioning. In its role as an anti-infective, ethanol acts as an osmolyte or dehydrating agent that disrupts the osmotic balance across cell membranes. ... Ethanol is known to affect a large number of membrane proteins that participate in signaling pathways such as neurotransmitter receptors, enzymes, and ion channels, and there is extensive evidence that ethanol interacts with a variety of neurotransmitters. The major actions of ethanol involve enhancing the inhibitory effects of gamma-aminobutyric acid (GABA) at GABAa receptors and blockade of the N-methyl-D-aspartate (NMDA) subtype of glutamate, an excitatory amine acid (EAA) receptor. Animal studies indicate that the acute effects of ethanol result from competitive inhibition of glycine binding to NMDA receptor and disruption of glutamatergic neurotransmission by inhibiting the response of the NMDA receptor. Persistent glycine antagonism and attenuation of glutamatergic neurotransmission by chronic ethanol exposure results in tolerance to ethanol by enhancing EAA neurotransmission and NMDA receptor upregulation. The latter appears to involve selective increases in NMDA R2B subunit concentrations and other molecular changes in specific brain loci. The abrupt withdrawal of ethanol thus produces a hyperexcitable state that leads to the ethanol withdrawal syndrome and excitotoxic neuronal death. GABA-mediated inhibition, which normally acts to limit excitation, is eliminated during ethanol withdrawal syndrome and further intensifies this excitation. In addition, NMDA receptors function to inhibit the release of dopamine in the nucleus accumbens and mesolimbic structures, which modulate the reinforcing action of addictive xenobiotics such as ethanol. By inhibiting NMDA receptor activity, ethanol could increase dopamine release from the nucleus accumbens and ventral tegmental area and could thus create dependence. Chronic ethanol administration also results in tolerance, dependence, and an ethanol withdrawal syndrome, mediated, in part, by desensitization and or downregulation of GABAa receptors. The development of alcoholic ketoacidosis (AKA) requires that a combination of physical and physiologic events occur. The normal response to starvation and depletion of hepatic glycogen stores is for amino acids to be converted to pyruvate. Pyruvate can serve as a substrate for gluconeogenesis, be converted to acetyl-CoA, which can enter the Krebs cycle or can be utilized in various biosynthetic pathways (eg, fatty acid, ketone bodies, cholesterol, and acetylcholine) ... Ethanol metabolism generates NADH, resulting in an excess of reducing potential. This high redox state favors the conversion of pyruvate to lactate, diverting pyruvate from being a substrate for gluconeogenesis. To compensate for the lack of normal metabolic substrates, the body mobilizes fat from adipose tissue and increased fatty acid metabolism as an alternative source of energy. This response is mediated by a decrease in insulin and an increased secretion of glucagon, catecholamines, growth hormone, and cortisol. Fatty acid metabolism results in the formation of acetyl-CoA and it combines with the excess acetate that is generated from ethanol metabolism to form acetoacetate. Most of the acetoacetate is reduced to beta-hydroxybutyrate due to the excess reducing potential or high redox state of the cell. Volume depletion interferes with the renal elimination of acetoacetate and beta-hydroxybutyrate, and contributes to the acidosis. An elevated lactate concentration may result from shunting from pyruvate or

Pharmacodynamics

Alcohol produces injury to cells by dehydration and precipitation of the cytoplasm or protoplasm. This accounts for its bacteriocidal and antifungal action. When alcohol is injected in close proximity to nerve tissues, it produces neuritis and nerve degeneration (neurolysis). Ninety to 98% of ethanol that enters the body is completely oxidized. Ethanol is also used as a cosolvent to dissolve many insoluble drugs and to serve as a mild sedative in some medicinal formulations. Ethanol also binds to GABA, glycine, NMDA receptors and modulates their effects. Ethanol is also metabolised by the hepatic enzyme alcohol dehydrogenase.
