Ipecac

Identification

Summary

Ipecac is an emetic agent used to induce vomiting in poisoning.

Generic Name
Ipecac
DrugBank Accession Number
DB13293
Background

Ipecac is obtained from the plant Cephaelis ipecacuanha and contains a number of emetic alkaloids including emetine and cephaeline.9 Ipecac was approved by Health Canada as an OTC but all those products are now discontinued.7 The FDA does not have currently any approved product containing ipecac, however, ipecac as an ingredient is accepted to be sold over the counter in packages of 1 fluid ounce (30 ml) for the emergency use to cause vomiting in poisoning.8

Pharmacology

Indication

Ipecac is indicated as an emetic agent for the induction of vomiting in poisoning victims who ingested systemic poison in order to prevent absorption of the chemicals through the gastrointestinal tract. In low doses, ipecac was also used as an expectorant.9

Reports have suggested that ipecac was vastly used in patients with eating disorders to produce vomiting.5

Pharmacodynamics

An effective and safe dose of ipecac may cause vomiting within 20 minutes of the administration.9 In prospective studies with children, the mean time to vomit was reported to be of 21.7 minutes.10

Mechanism of action

The emetic components of ipecac, emetine and cephaeline, act centrally and locally in the gastrointestinal tract to cause vomiting.9 The mechanism by which ipecac performs his effect is by irritating the stomach lining and chemically stimulating the chemoreceptor trigger zone.6

Absorption

The main components of ipecac are rapidly absorbed from the GI tract, this absorption depends on the amount of emesis produced by the administered dose. The peak plasma concentration of 10-16 ng/ml is attained 20 minutes after first administration.5 The bioavailability of ipecac is reduced over time from 67-11% after 5-60 minutes of administration.3

Volume of distribution

The volume of distribution is thought to be large based on the prolonged excretion.5

Protein binding

This pharmacokinetic property is not relevant as the absorbed dose of ipecac is minimal.

Metabolism

The main components of ipecac have been shown in microsomal enzyme systems that emetine is converted to cephaeline and 9-O-demethylemetine by CYP2D6. On the other hand, CYP3A4 produces the transformation of emetine to 9-O-demethylemetine and 10-O-demethylemetine. In preclinical studies, it was shown that cephaline is conjugated with glucuronice to form cephaeline-6'-O-glucuronide for biliary excretion whereas emetine gets demethylated to cephaline and 9-O-demethylemetine before glucuronidation.5

Route of elimination

Due to the emetic function, even 76% of the administered dose is vomited. From the absorbed dose, the elimination from plasma is relatively rapid. In some clinical trials, the alkaloids were not observed in plasma 6 hours after administration. When the patient does not vomit any part of the administered dose, there could be traces in plasma after 24 hours. The component alkaloids are eliminated via the bile and urine as it has been observed a persistence in urine after chronic administration.5 Biliary and urinary excretion of ipecac corresponds to 57.5% and 16.5% of the administered dose respectively. From the excreted dose, unchanged cephaeline accountd for 42.4% of the eliminated dose in feces.4

Half-life

The effect of ipecac is done in about 20 minutes and the elimination of the little-absorbed dose is reported to be very rapid. Thus, the half-life is thought to be of about 0.5-1 hour.5

Clearance

The urinary excretion of the main components of ipecac accounts for 75% of the administered dose 48 hours after initial administration.6

Toxicity

An overdose of an ipecac preparation may cause serious poisoning. If emesis is not provoked after two doses of ipecac, a gastric lavage is recommended.9 The overdose of the components such as emetine is reported to cause the onset of myopathy. Chronic use of this drug has been indicated to produce muscle weakness, waddling gait, dyspnea, left atrial enlargement and reduced left ventricular ejection fraction.5

General Function
A cytochrome P450 monooxygenase involved in the metabolism of fatty acids, steroids and retinoids (PubMed:18698000, PubMed:19965576, PubMed:20972997, PubMed:21289075, 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) (PubMed:18698000, PubMed:19965576, PubMed:20972997, PubMed:21289075, PubMed:21576599). Catalyzes the epoxidation of double bonds of polyunsaturated fatty acids (PUFA) (PubMed:19965576, PubMed:20972997). Metabolizes endocannabinoid arachidonoylethanolamide (anandamide) to 20-hydroxyeicosatetraenoic acid ethanolamide (20-HETE-EA) and 8,9-, 11,12-, and 14,15-epoxyeicosatrienoic acid ethanolamides (EpETrE-EAs), potentially modulating endocannabinoid system signaling (PubMed:18698000, PubMed:21289075). Catalyzes the hydroxylation of carbon-hydrogen bonds. Metabolizes cholesterol toward 25-hydroxycholesterol, a physiological regulator of cellular cholesterol homeostasis (PubMed:21576599). Catalyzes the oxidative transformations of all-trans retinol to all-trans retinal, a precursor for the active form all-trans-retinoic acid (PubMed:10681376). Also involved in the oxidative metabolism of drugs such as antiarrhythmics, adrenoceptor antagonists, and tricyclic antidepressants

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)
