Umifenovir is currently licensed in China and Russia for the prophylaxis and treatment of influenza and other respiratory viral infections. It has demonstrated activity against a number of viruses and has been investigated in the treatment of _Flavivirus_, Zika virus, foot-and-mouth disease, Lassa virus, Ebola virus, and herpes simplex. In addition, it has shown _in vitro_ activity against hepatitis B and C viruses, chikungunya virus, reovirus, Hantaan virus, and coxsackie virus B5. Umifenovir is currently being investigated as a potential treatment and prophylactic agent for the prevention of COVID-19 caused by SARS-CoV-2 infections.
Umifenovir exerts its antiviral effects via both direct-acting virucidal activity and by inhibiting one (or several) stage(s) of the viral life cycle. Its broad-spectrum of activity covers both enveloped and non-enveloped RNA and DNA viruses. It is relatively well-tolerated and possesses a large therapeutic window - weight-based doses up to 100-fold greater than those used in humans failed to produce any pathological changes in test animals. Umifenovir does not appear to result in significant viral resistance. Instances of umifenovir-resistant influenza virus demonstrated a single mutation in the HA2 subunit of influenza hemagglutinin, suggesting resistance is conferred by prevention of umifenovirs activity related to membrane fusion. The mechanism through which other viruses may become resistant to umifenovir requires further study.

Absorption
Umifenovir is rapidly absorbed following oral administration, with an estimated Tmax between 0.65-1.8 hours. The Cmax has been estimated as 415 - 467 ng/mL and appears to increase linearly with dose, and the AUC0-inf following oral administration has been estimated to be approximately 2200 ng/mL/h.
Route of Elimination
The major route of elimination is via the feces. Approximately 40% of an ingested dose is excreted unchanged, of which 38.9% is excreted in the bile and 0.12% excreted through the kidneys. The total recovery of parent drug and metabolites in the urine accounts for less than 1% of an ingested dose.
Volume of Distribution
Data regarding the volume of distribution of umifenovir are currently unavailable.
Clearance
In a study involving healthy male Chinese volunteers, the oral clearance of umifenovir was found to be 99 34 L/h.
Umifenovir is highly metabolized in the body, primarily in hepatic and intestinal microsomess, with approximately 33 metabolites having been observed in human plasma, urine, and feces. The principal phase I metabolic pathways include sulfoxidation, N-demethylation, and hydroxylation, followed by phase II sulfate and glucuronide conjugation. In the urine, the major metabolites were sulfate and glucuronide conjugates, while the major species in the feces was unchanged parent drug (~40%) and the M10 metabolite (~3.0%). In the plasma, the principal metabolites are M6-1, M5, and M8 - of these, M6-1 appears of most importance given its high plasma exposure and long elimination half-life (~25h), making it a potentially important player in the safety and efficacy of umifenovir. Enzymes involved in the metabolism of umifenovir include members of the cytochrome P450 family (primarily CYP3A4), flavin-containing monooxygenase (FMO) family, and UDP-glucuronosyltransferase (UGT) family (specifically UGT1A9 and UGT2B7).
Arbidol has known human metabolites that include (2S,3S,4S,5R)-6-[6-bromo-4-[(dimethylamino)methyl]-3-ethoxycarbonyl-1-methyl-2-(phenylsulfanylmethyl)indol-5-yl]oxy-3,4,5-trihydroxyoxane-2-carboxylic acid.

The half-life of umifenovir following oral administration has been estimated to be between 17-21 hours. Serum half-lives of the M5, M6-1, and M8 metabolites were found to be 26.3 5.9, 25.0 5.4, and 25.7 8.8, respectively.
Umifenovir is considered both a direct-acting antiviral (DAA) due to direct virucidal effects and a host-targeting agent (HTA) due to effects on one or multiple stages of viral life cycle (e.g. attachment, internalization), and its broad-spectrum antiviral activity is thought to be due to this dual activity. It is a hydrophobic molecule capable of forming aromatic stacking interactions with certain amino acid residues (e.g. tyrosine, tryptophan), which contributes to its ability to directly act against viruses. Antiviral activity may also be due to interactions with aromatic residues within the viral glycoproteins involved in fusion and cellular recognition, with the plasma membrane to interfere with clathrin-mediated exocytosis and intracellular trafficking, or directly with the viral lipid envelope itself (in enveloped viruses). Interactions at the plasma membrane may also serve to stabilize it and prevent viral entry (e.g. stabilizing influenza hemagglutinin inhibits the fusion step necessary for viral entry). Due to umifenovirs ability to interact with both viral proteins and lipids, it may also interfere with later stages of the viral life cycle. Some virus families, such as _Flaviviridae_, replicate in a subcellular compartment called the membranous web - this web requires lipid-protein interactions that may be hindered by umifenovir. Similarly, viral assembly of hepatitis C viruses is contingent upon the assembly of lipoproteins, presenting another potential target.

ABOUT THIS PAGE
A Umifenovir manufacturer is defined as any person or entity involved in the manufacture, preparation, processing, compounding or propagation of Umifenovir, including repackagers and relabelers. The FDA regulates Umifenovir manufacturers to ensure that their products comply with relevant laws and regulations and are safe and effective to use. Umifenovir API Manufacturers are required to adhere to Good Manufacturing Practices (GMP) to ensure that their products are consistently manufactured to meet established quality criteria.

National Drug Code is a comprehensive database maintained by the FDA that contains information on all drugs marketed in the US. This directory includes information about finished drug products, unfinished drug products, and compounded drug products, including those containing Umifenovir as an active pharmaceutical ingredient (API).
The FDA updates the NDC directory daily. The NDC numbers for Umifenovir API and other APIs are published in this directory by the FDA.
The NDC unfinished drugs database includes product listing information submitted for all unfinished drugs, such as active pharmaceutical ingredients (APIs), drugs intended for further processing and bulk drug substances for compounding.
Pharmaceutical companies that manufacture Umifenovir as an active pharmaceutical ingredient (API) must furnish the FDA with an updated record of all drugs that they produce, prepare, propagate, compound, or process for commercial distribution in the US at their facilities.
The NDC directory also contains data on finished compounded human drug products that contain Umifenovir and are produced by outsourcing facilities. While these outsourcing facilities are not mandated to assign a Umifenovir NDC to their finished compounded human drug products, they may choose to do so.

Umifenovir Active pharmaceutical ingredient (API) is produced in GMP-certified manufacturing facility.
GMP stands for Good Manufacturing Practices, which is a system used in the pharmaceutical industry to make sure that goods are regularly produced and monitored in accordance with quality standards. The FDA’s current Good Manufacturing Practices requirements are referred to as cGMP or current GMP which indicates that the company follows the most recent GMP specifications. The World Health Organization (WHO) has its own set of GMP guidelines, called the WHO GMP. Different countries can also set their own guidelines for GMP like China (Chinese GMP) or the EU (EU GMP).
PharmaCompass offers a list of Umifenovir GMP manufacturers, exporters & distributors, which can be sorted by USDMF, JDMF, KDMF, CEP (COS), WC, API price, and more, enabling you to easily find the right Umifenovir GMP manufacturer or Umifenovir GMP API supplier for your needs.
A Umifenovir CoA (Certificate of Analysis) is a formal document that attests to Umifenovir's compliance with Umifenovir specifications and serves as a tool for batch-level quality control.
Umifenovir CoA mostly includes findings from lab analyses of a specific batch. For each Umifenovir CoA document that a company creates, the USFDA specifies specific requirements, such as supplier information, material identification, transportation data, evidence of conformity and signature data.
Umifenovir may be tested according to a variety of international standards, such as European Pharmacopoeia (Umifenovir EP), Umifenovir JP (Japanese Pharmacopeia) and the US Pharmacopoeia (Umifenovir USP).
