heparin	A highly acidic mucopolysaccharide formed of equal parts of sulfated D-glucosamine and D-glucuronic acid with sulfaminic bridges. The molecular weight ranges from six to twenty thousand. Heparin occurs in and is obtained from liver, lung, mast cells, etc., of vertebrates. Its function is unknown, but it is used to prevent blood clotting in vivo and vitro, in the form of many different salts.
protamine sulfate	A group of simple proteins that yield basic amino acids on hydrolysis and that occur combined with nucleic acid in the sperm of fish. Protamines contain very few kinds of amino acids. Protamine sulfate combines with heparin to form a stable inactive complex; it is used to neutralize the anticoagulant action of heparin in the treatment of heparin overdose. (From Merck Index, 11th ed; Martindale, The Extra Pharmacopoeia, 30th ed, p692)
fondaparinux	Synthetic pentasaccharide that mediates the interaction of HEPARIN with ANTITHROMBINS and inhibits FACTOR Xa; it is used for prevention of VENOUS THROMBOEMBOLISM after surgery.
argatroban
lepirudin
andexanet alfa	Andexanet alfa is a recombinant form of human FXa protein that has been modified to lack FXa enzymatic activity. The active site serine was substituted with alanine, rendering the molecule unable to cleave and activate prothrombin, and the gamma-carboxyglutamic acid (Gla) domain was removed to eliminate the ability of the protein to assemble into the prothrombinase complex, thus removing any anti-coagulant effects. Andexanet alfa is a specific reversal agent for FXa inhibitors. The predominant mechanism of action is the binding and sequestration of the FXa inhibitor, although there may be a minor contribution from the inhibition of tissue factor pathway inhibitor (TFPI) activity through binding to TFPI. The interaction between andexanet alfa and TFPI has not been fully characterized. Andexanet alfa binds direct FXa inhibitors with high affinity, making them unavailable to exert their anticoagulant effects
glucose	A primary source of energy for living organisms. It is naturally occurring and is found in fruits and other parts of plants in its free state. It is used therapeutically in fluid and nutrient replacement.
bemiparin	A low-molecular-weight fragment of heparin, prepared by nitrous acid depolymerization of porcine mucosal heparin. The mean molecular weight is 4000-6000 daltons. It is used therapeutically as an antithrombotic agent. (From Merck Index, 11th ed)
enoxaparin sodium	Low-molecular-weight fragment of heparin, having a 4-enopyranosuronate sodium structure at the non-reducing end of the chain. It is prepared by depolymerization of the benzylic ester of porcine mucosal heparin. Therapeutically, it is used as an antithrombotic agent. (From Merck Index, 11th ed)
nadroparin calcium	A low molecular weight heparin (LMWH) composed of a heterogeneous mixture of sulfated polysaccharide glycosaminoglycan chains obtained by depolymerisation of porcine mucosal sodium heparin, extraction/purification and conversion to the calcium salt. Nadroparin binds to antithrombin III (ATIII) and inhibits the activity of activated factor X (factor Xa), thereby inhibiting the final common pathway of the coagulation cascade and preventing the formation of a cross-linked fibrin clot
pentosan polysulfate	A sulfated pentosyl polysaccharide with heparin-like properties.

DrugCentral Search Overview

Drug search example:

Generic drug names, drug synonyms, trade names terms can be used to search for drugs. Example search for Lipitor can query using either “Atorvastatin” or “Lipitor”.A comprehensive list of drug development codes and salt or ester forms are also stored in the database and can be used as search terms, for example search for "rosuvastatin" the following terms can be used: "rosuvastatin calcium" or "ZD4522".

Disease search example:

Supported disease terms are SNOMED-CT and OMOP vocabulary terms. Disease annotations for drugs approved before 2012 originate from OMOP vocabulary mappings. For drugs approved after 2012 disease annotations are extracted manually from approved drug labels and mapped to SNOMED-CT concepts.

Example search for “Chronic Hepatitis C” returns the list of antiviral drugs indicated to treat “Chronic Hepatitis C” followed by drugs contra-indicated in hepatitis C.

New! Substructure Search:
The current update supports chemical substructure searching. Typing a SMILES string in the DrugCentral Substructure search bar launches a chemical substructure search that finds matching compounds in DrugCentral. E.g., N1cnccc1 . SMILES strings can be located on all Drug Cards under "Description".

New! FDA Adverse Event Reporting System:
The 2021 DrugCentral update, we separately calculated FAERS for men and women to enable research on sex differences in drug safety. The 2022 version goes further by computing adverse drug event scores granulated by age: pediatric data (FAERS_PED) covers patients from 1 day to 17 years, and geriatric data (FAERS_GER) focuses on elderly patients over 65 years of age, respectively. Female, Male, Geriatric & Pediatrics. E.g., amfetamine

New! Target Cards:
To perform a target card search enter a Uniprot target Accession ID e.g., P23975. The target cards depict the "Accession", "Swissprot", "Organism", "Gene" & "Target class" followed by "Drug relations" where the drugs "Bioactivity mechanism-of-actions" are identified.

Target search example:
Supported target search terms are HUGO gene symbols, Uniprot accessions and target names, and Swissprot identifiers. Example search for drugs targeting Mu-type opioid receptor can be run using either of the terms: “OPRM1”, P35372, “OPRM_HUMAN”, full or partial Uniprot target name. Returned drugs are ranked using the following criteria: top ranked drugs have mechanism of action target Mu-type opioid receptor, next in the list are drugs with potencies measured against this receptor.

In collaboration with the IDG
New! Veterinary Drugs, Uses & Products:

Drug Central now contains Veterinary Drugs, Uses & Products. The current update adds 1805 bioactivities for 226 veterinary drugs and 804 targets. DrugCentral veterinary data contains application numbers and types, trade names, applicant names, and prescription types for 1492 drug products as referenced in FDA’s Green Book. DrugCentral currently holds 1664 indications (pairs of drug and concept names) for 34 species. Dogs, cattle, and cats sum up to 63% of the indications covered by 193 veterinary drugs. Veterinary Drug Use can be found on each drug card by selecting the sub menu link: 🐶 Veterinary Use on the drug card. E.g., enrofloxacin
Pharmacologic action search example:

Supported pharmacologic action terms are MeSH, FDA [EPC, MoA, PE], ChEBI action roles.

Example search for “HMG-CoA Reductase Inhibitor” FDA EPC term for statin drugs returns list of all statin drugs classified by FDA as HMG-CoA reductase inhibitors.

Ranked result list is annotated with 4 level ranking system ordered from highest to lowest:

A - query term matched drug name or synonyms, mechanism of action target, or drug indication.

B - query term matched disease term in drug contraindications or off-label uses, targets listed in drug bioactivity profiles (not MoA targets), or pharmacologic action descriptions.

C - query term matched short drug description text.

D - query term matched full text in FDA drug labels.
