Substance name: Vildagliptin
Chemical class: Dipeptidyl peptidase-4 (DPP-4) inhibitor
Main use: Oral treatment for type 2 diabetes
Form: Typically white to off-white crystalline powder; no strong odor
Common routes of exposure: Inhalation, skin contact, ingestion, accidental eye exposure
Synonyms: Alpha-cyano-N-(3-hydroxy-1-adamantyl)-N-pyridin-3-ylacetamide
Physical hazards: Not flammable under standard lab conditions; fine powders may present combustibility risk in large amounts
Health hazards: Can irritate eyes and skin; ingestion may cause gastrointestinal discomfort or hypoglycemic symptoms for persons with diabetes
Environmental hazards: Avoid release to soil and waterways; aquatic toxicity potential is unclear.
Chronic exposure risk: Regular or high-dose exposure can increase health risks, including possible impact on pancreas.
Active ingredient: Vildagliptin (over 98% in pure forms)
Common impurities: Trace organic solvents, particulate matter resulting from synthesis, potential stabilizers depending on storage method
Inhalation: Move to fresh air immediately, monitor for respiratory symptoms like cough or shortness of breath.
Skin contact: Wash skin thoroughly with soap and water.
Eye contact: Rinse with running water for several minutes, remove contact lenses if possible.
Ingestion: Rinse mouth, seek medical advice, watch for dizziness, vomiting, or abnormal blood sugar.
Suitable extinguishing media: Foam, CO2, dry powder, or water spray.
Special hazards: Powder form can float and ignite dust in rare situations.
Protective equipment: Standard firefighter gear, chemical mask for smoke exposure
Combustion byproducts: Noxious gases such as nitrogen oxides and carbon monoxide can result from fire.
Personal precautions: Ventilate the area, use gloves, goggles, avoid dust generation
Environmental precautions: Block powder from entering drains and watercourses
Cleanup methods: Sweep loose powder carefully into sealed containers; dampen with water to reduce dust formation
Handling: Operate within fume hood or controlled area for bulk samples, minimize prolonged skin contact
Storage: Keep tightly sealed, dry, and in cool location away from sunlight; avoid strong oxidizing agents.
Special considerations: Store away from food and water supplies to prevent contamination
Engineering controls: Local exhaust ventilation improves air quality in preparation and weighing spaces
Personal protection: Gloves (nitrile recommended), safety glasses, lab coat; respirators if forming dust
Work hygiene: Wash hands thoroughly after handling and before eating or drinking, do not eat or drink in handling area
Appearance: White to pale cream crystalline powder
Odor: Odorless
Melting Point: Roughly 140–150°C
Solubility: Slightly soluble in water; more soluble in organic solvents
Vapor Pressure: Not volatile at room temperature
Stability: Stable in cool, dry conditions away from sunlight
Chemical stability: Remains stable under standard conditions
Hazardous reactions: Contact with strong oxidizers can cause decomposition; avoid heat and open flame
Decomposition products: Heating may produce nitrogen oxides and cyanide derivatives
Acute toxicity: Low toxicity by oral or dermal exposure under normal handling, but large accidental doses can trigger low blood sugar or gastrointestinal symptoms
Eye contact: May cause irritation and redness
Chronic toxicity: Prolonged or repeated exposure might lead to headaches, fatigue, and increased risk of pancreatitis in those predisposed
Allergenicity: No strong allergenic incidents widely reported, but any new substance carries potential risk for sensitive individuals
Environmental fate: Not expected to persist in soil or water for prolonged periods; breakdown involves basic organic processes
Aquatic toxicity: Direct data is sparse, but toxicity to aquatic organisms should be assumed until proven otherwise
Bioaccumulation: Expected to be low based on structure and water solubility
Waste method: Dispose as pharmaceutical waste through licensed waste handlers
Avoid: Flushing to sewer or disposing with normal household refuse
Container hygiene: Triple rinse or deface all chemical containers before disposal
Shipping regulations: Not classified as a dangerous good for most road, air, or sea transport
Special precautions: Avoid spills and prevent moisture exposure during shipment; transport in sealed packaging
Status: Approved drug ingredient in many countries for use in pharmaceuticals; not subject to major hazardous chemical restrictions
Labelling requirements: GHS labeling with hazard symbols if handled in bulk form
Worker protection: Subject to occupational health regulations covering safe handling of pharmaceuticals
Disposal compliance: Subject to local and national regulations for handling of unused pharmaceuticals
