Identification
- Summary
Ergoloid mesylate is a nootropic with an unknown mechanism of action indicated in individuals over sixty who manifest signs and symptoms of an idiopathic decline in mental capacity.
- Brand Names
- Hydergine
- Generic Name
- Ergoloid mesylate
- DrugBank Accession Number
- DB01049
- Background
Ergoloid Mesylate is an equiproportional preparation of three different ergotamantriones: dihydroergocornine, dihydroergocristine, and dihydroergocryptine.1 All these components are produced by the fungus Claviceps purpurea and are all derivatives of the tetracyclic compound 6-methylergonovine.7 The derivatives of this fungus are identified to be about 350 different substances from which the components of the ergoloid mesylate mixture are composed of the dihydrogenated ergot alkaloid derivatives.3 The mixture of ergoloid mesylate was first developed by Novartis and FDA approved on November 5, 1953, but this specific formulation is now discontinued.10Later in 1991, the mixture of ergoloid mesylates was retaken by Sun Pharmaceutical Industries and approved by the FDA.11 To know more about the individual components of the ergoloid mixture, please visit Epicriptine, Dihydro-alpha-ergocryptine, Dihydroergocornine and Dihydroergocristine.

Pharmacology
- Indication
It was labeled by the FDA for the treatment of symptoms of an idiopathic decline in the mental capacity not related to a potentially reversible condition2 as well as for age-related cognitive impairment.4 The prescription of this drug is conditioned to the corroboration that the patient is not suffering from a potentially reversible and treatable condition especially delirium and dementiform illness secondary to systemic disease, primary neurological disease or primary mood disturbance.12 To know more about the individual components of the ergoloid mixture, please visit Dihydroergocristine and Dihydro-alpha-ergocryptine

- Pharmacodynamics
The mechanism of action of ergoloid mesylate is not completely established but it is thought that it increases both the blood flow and cerebral metabolism. Some studies have shown a significant improvement in alertness and memory, as well as a decline in confusion while some other benefits have shown a lack of effect.2 Its action produces a damper in the impulses from the vasomotor center which reduces the vascular tone which translates in the slow of pulse rate, prevention of compensatory tachycardia.3 To know more about the individual components of the ergoloid mixture, please visit Dihydro-alpha-ergocryptine, Dihydroergocornine and Dihydroergocristine.
- Mechanism of action
The general mechanism of action of ergoloid mesylate is the dual action of partial agonism/antagonism of adrenergic, dopaminergic and serotonergic receptors. The pharmacological activity is determined by the degree of activity of each component at the receptor site.7 To know more about the individual components of the ergoloid mixture, please visit Epicriptine, Dihydro-alpha-ergocryptine, Dihydroergocornine and Dihydroergocristine.
Target Actions Organism ADopamine receptor antagonistagonistHumans AAlpha adrenergic receptor antagonistagonistHumans ABeta adrenergic receptor antagonistagonistHumans ASerotonin Receptors antagonistagonistHumans - Absorption
The maximal plasma concentration of the components of the mixture of ergoloid mesylates is approximately 0.04 mcg/l. The analysis of the concentration of the major metabolites of each component indicates that all ergoloid mesylate are rapidly transformed after absorption. This finding is supported as they were found in one order of magnitude higher in concentration when compared to the original form.3 Ergoloid mesylate seems to have a very low absorption of only 25%. From this absorption by the GI tract, approximately 50% of the absorbed dose is eliminated by first-pass metabolism. After absorption, the maximal plasma concentration is attained after 3-4 hours and the oral bioavailability is very low.6 Simultaneous food ingestion has no effect on the extent of absorption but it does lower the absorption rate.5 To know more about the individual components of the ergoloid mixture, please visit Dihydro-alpha-ergocryptine, Dihydroergocornine and Dihydroergocristine.
- Volume of distribution
The volume of distribution is about 2 L/kg.7 To know more about the individual components of the ergoloid mixture, please visit Dihydro-alpha-ergocryptine and Dihydroergocristine.
- Protein binding
Ergoloid mesylate presents a very large plasma protein binding that accounts for 81% of the administered dose.14 To know more about the individual components of the ergoloid mixture, please visit Dihydro-alpha-ergocryptine and Dihydroergocristine.
- Metabolism
Most of the metabolism of ergoloid mesylate is hepatic and it is performed very rapidly after absorption. After exposition in vitro, the major metabolites identified are hydroxy-dihydroergocornine, hydroxy-dihydroergocryptine and hydroxy-dihydroergocristine.4 All metabolic transformations seem to be related to the activity of the cytochrome CYP3A4.13 To know more about the individual components of the ergoloid mixture, please visit Dihydro-alpha-ergocryptine, Dihydroergocornine and Dihydroergocristine.
- Route of elimination
The ergoloid mesylate mixture is mainly excreted via bile in feces. The ratio of the eliminated dose via urine after intravenous and oral administration is 8.4% and 2% respectively.6 Urinary excretion of the unchanged drug is very small and bile excretion is represented mainly by ergot metabolites conformed as conjugated compounds.9 To know more about the individual components of the ergoloid mixture, please visit Dihydro-alpha-ergocryptine, Dihydroergocornine and Dihydroergocristine.
- Half-life
The reported plasma half-life of ergoloid mesylate is 3.5 hours while the terminal half-life is of 13 hours.6 To know more about the individual components of the ergoloid mixture, please visit Dihydro-alpha-ergocryptine.

- General Function
- G-protein coupled receptor for 5-hydroxytryptamine (serotonin) (PubMed:22957663, PubMed:3138543, PubMed:33762731, PubMed:37935376, PubMed:37935377, PubMed:8138923, PubMed:8393041). Also functions as a receptor for various drugs and psychoactive substances (PubMed:22957663, PubMed:3138543, PubMed:33762731, PubMed:38552625, PubMed:8138923, PubMed:8393041). Ligand binding causes a conformation change that triggers signaling via guanine nucleotide-binding proteins (G proteins) and modulates the activity of downstream effectors, such as adenylate cyclase (PubMed:22957663, PubMed:3138543, PubMed:33762731, PubMed:8138923, PubMed:8393041). HTR1A is coupled to G(i)/G(o) G alpha proteins and mediates inhibitory neurotransmission: signaling inhibits adenylate cyclase activity and activates a phosphatidylinositol-calcium second messenger system that regulates the release of Ca(2+) ions from intracellular stores (PubMed:33762731, PubMed:35610220). Beta-arrestin family members regulate signaling by mediating both receptor desensitization and resensitization processes (PubMed:18476671, PubMed:20363322, PubMed:20945968). Plays a role in the regulation of 5-hydroxytryptamine release and in the regulation of dopamine and 5-hydroxytryptamine metabolism (PubMed:18476671, PubMed:20363322, PubMed:20945968). Plays a role in the regulation of dopamine and 5-hydroxytryptamine levels in the brain, and thereby affects neural activity, mood and behavior (PubMed:18476671, PubMed:20363322, PubMed:20945968). Plays a role in the response to anxiogenic stimuli (PubMed:18476671, PubMed:20363322, PubMed:20945968)

- General Function
- A cytochrome P450 monooxygenase involved in the metabolism of sterols, steroid hormones, retinoids and fatty acids (PubMed:10681376, PubMed:11093772, PubMed:11555828, PubMed:12865317, PubMed:14559847, PubMed:15373842, PubMed:15764715, PubMed:19965576, PubMed:20702771, PubMed:21490593, PubMed:21576599). Mechanistically, uses molecular oxygen inserting one oxygen atom into a substrate, and reducing the second into a water molecule, with two electrons provided by NADPH via cytochrome P450 reductase (NADPH--hemoprotein reductase). Catalyzes the hydroxylation of carbon-hydrogen bonds (PubMed:12865317, PubMed:14559847, PubMed:15373842, PubMed:15764715, PubMed:21490593, PubMed:21576599, PubMed:2732228). Exhibits high catalytic activity for the formation of hydroxyestrogens from estrone (E1) and 17beta-estradiol (E2), namely 2-hydroxy E1 and E2, as well as D-ring hydroxylated E1 and E2 at the C-16 position (PubMed:11555828, PubMed:12865317, PubMed:14559847). Plays a role in the metabolism of androgens, particularly in oxidative deactivation of testosterone (PubMed:15373842, PubMed:15764715, PubMed:22773874, PubMed:2732228). Metabolizes testosterone to less biologically active 2beta- and 6beta-hydroxytestosterones (PubMed:15373842, PubMed:15764715, PubMed:2732228). Contributes to the formation of hydroxycholesterols (oxysterols), particularly A-ring hydroxylated cholesterol at the C-4beta position, and side chain hydroxylated cholesterol at the C-25 position, likely contributing to cholesterol degradation and bile acid biosynthesis (PubMed:21576599). Catalyzes bisallylic hydroxylation of polyunsaturated fatty acids (PUFA) (PubMed:9435160). Catalyzes the epoxidation of double bonds of PUFA with a preference for the last double bond (PubMed:19965576). Metabolizes endocannabinoid arachidonoylethanolamide (anandamide) to 8,9-, 11,12-, and 14,15-epoxyeicosatrienoic acid ethanolamides (EpETrE-EAs), potentially modulating endocannabinoid system signaling (PubMed:20702771). Plays a role in the metabolism of retinoids. Displays high catalytic activity for oxidation of all-trans-retinol to all-trans-retinal, a rate-limiting step for the biosynthesis of all-trans-retinoic acid (atRA) (PubMed:10681376). Further metabolizes atRA toward 4-hydroxyretinoate and may play a role in hepatic atRA clearance (PubMed:11093772). Responsible for oxidative metabolism of xenobiotics. Acts as a 2-exo-monooxygenase for plant lipid 1,8-cineole (eucalyptol) (PubMed:11159812). Metabolizes the majority of the administered drugs. Catalyzes sulfoxidation of the anthelmintics albendazole and fenbendazole (PubMed:10759686). Hydroxylates antimalarial drug quinine (PubMed:8968357). Acts as a 1,4-cineole 2-exo-monooxygenase (PubMed:11695850). Also involved in vitamin D catabolism and calcium homeostasis. Catalyzes the inactivation of the active hormone calcitriol (1-alpha,25-dihydroxyvitamin D(3)) (PubMed:29461981)
