| Entsorgungsverfahren | SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air qualitypotential migration in soil or watereffects on animal, aquatic, and plant lifeand conformance with environmental and public health regulations. |

| Umweltverhalten | TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 40,000(SRC), determined from a structure estimation method(2), indicates that tirofiban is expected to be immobile in soil(SRC). Volatilization of tirofiban from moist soil surfaces is not expected to be an important fate process(SRC) given an estimated Henry's Law constant of 7.4X10-15 atm-cu m/mole(SRC), using a fragment constant estimation method(3). Estimated pKa values of 3.3 (carboxylic acid group) and 10.5 (amino group)(4) indicate that tirofiban will exist as a zwitterion at pH values of 5 to 9 and therefore volatilization from moist soil is not expected to be an important fate process. Tirofiban is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 5.2X10-16 mm Hg(SRC), determined from a fragment constant method(5). Biodegradation data were not available(SRC, 2005).AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 40,000(SRC), determined from a structure estimation method(2), indicates that tirofiban is expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is not expected(3) based upon an estimated Henry's Law constant of 7.4X10-15 atm-cu m/mole(SRC), developed using a fragment constant estimation method(4). Estimated pKa values of 3.3 (carboxylic acid group) and 10.5 (amino group)(5) indicate that tirofiban will exist as a zwitterion at pH values of 5 to 9 and therefore volatilization from water surfaces is not expected to be an important fate process. According to a classification scheme(6), an estimated BCF of 3.2(SRC), from an estimated log Kow of 1.4(7) and a regression derived equation(8), suggests the potential for bioconcentration in aquatic organisms is low. Biodegradation data were not available(SRC, 2005).ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), tirofiban, which has an estimated vapor pressure of 5.2X10-16 mm Hg at 25 °C(SRC), determined from a fragment constant method(2), is expected to exist solely in the particulate phase in the ambient atmosphere. Particulate-phase tirofiban may be removed from the air by wet and dry deposition(SRC). Tirofiban does not contain chromophores that absorb light at wavelengths >290 nm and therefore is not be expected to be susceptible to direct photolysis by sunlight(SRC). |
|---|
| Soil Adsorption/Mobility | Using a structure estimation method based on molecular connectivity indices(1), the Koc for tirofiban can be estimated to be 40,000(SRC). According to a classification scheme(2), this estimated Koc value suggests that tirofiban is expected to be immobile in soil. |

| Human Toxicity Excerpts | /SIGNS AND SYMPTOMS/ Limited information is available on the acute toxicity of tirofiban. In general, overdosage of tirofiban in humans may be expected to produce effects that are extensions of the pharmacologic and adverse effects of the drug, predominantly bleeding. The most frequently reported manifestation of overdosage was bleeding, principally minor bleeding at mucocutaneous and cardiac catheterization sites. Inadvertent overdosage with tirofiban has occurred in doses of up to twice those recommended for an IV loading infusion and up to 9.8 times higher than the recommended maintenance infusion dosage of 0.15 ug/kg per minute |

| Environmental Bioconcentration | An estimated BCF of 3.2 was calculated for tirofiban(SRC), using an estimated log Kow of 1.4(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC). |

| Volatilization from Water/Soil | The Henry's Law constant for tirofiban is estimated as 7.4X10-15 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This Henry's Law constant indicates that tirofiban is expected to be essentially nonvolatile from water surfaces(2). Estimated pKa values of 3.3 (carboxylic acid group) and 10.5 (amino group)(3) indicate that tirofiban will exist as a zwitterion at pH values of 5 to 9 and therefore volatilization from moist soil surfaces and water surfaces is not expected to be an important fate process. Tirofiban is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 5.2X10-16 mm Hg(SRC), determined from a fragment constant method(4). |

| Non-Human Toxicity Excerpts | /LABORATORY ANIMALS: Developmental or Reproductive Toxicity/ Studies with tirofiban HCl at intravenous doses up to 5 mg/kg/day ... for rats and rabbits ... have revealed no harm to the fetus. /Tirofiban hydrochloride//LABORATORY ANIMALS: Developmental or Reproductive Toxicity/ Fertility and reproductive performance were not affected in studies with male and female rats given intravenous doses of tirofiban hydrochloride up to 5 mg/kg/day./GENOTOXICITY/ Tirofiban HCl was negative in the in vitro microbial mutagenesis and V-79 mammalian cell mutagenesis assays. In addition, there was no evidence of direct genotoxicity in the in vitro alkaline elution and in vitro chromosomal aberration assays. There was no induction of chromosomal aberrations in bone marrow cells of male mice after the administration of intravenous doses up to 5 mg tirofiban/kg. /Tirofiban hydrochloride/ |

| Environmental Abiotic Degradation | Tirofiban is not expected to undergo hydrolysis in the environment due to the lack of hydrolyzable functional groups(1). Tirofiban does not contain chromophores that absorb light at wavelengths >290 nm and therefore is not be expected to be susceptible to direct photolysis by sunlight(SRC). |
|---|
| Probable Routes of Human Exposure | Occupational exposure to tirofiban may occur through inhalation and dermal contact with this compound at workplaces where tirofiban is produced or used. Exposure to the drug among the general population exposure may be limited to those individuals being administered tirofiban (an antithrombotic). (SRC) |

| Environmental Fate/Exposure Summary | Tirofiban's production and use as an antithrombotic may result in its release to the environment through various waste streams. If released to air, an estimated vapor pressure of 5.2X10-16 mm Hg at 25 °C indicates tirofiban will exist solely in the particulate phase in the ambient atmosphere. Particulate-phase tirofiban will be removed from the atmosphere by wet and dry deposition. Tirofiban does not contain chromophores that absorb light at wavelengths >290 nm and therefore is not be expected to be susceptible to direct photolysis by sunlight. If released to soil, tirofiban is expected to have no mobility based upon an estimated Koc of 40,000. Volatilization from moist soil surfaces is not expected to be an important fate process based upon the estimated Henry's Law constant of 7.4X10-15 atm-cu m/mol and estimated pKa values. A pKa of 3.3 (carboxylic acid group) and a pKa of 10.5 (amine group) indicate that tirofiban will exist as a zwitterion at environmental pH and therefore volatilization from moist soil is not expected to be an important fate process. Tirofiban is not expected to volatilize from dry soil surfaces based upon its vapor pressure. If released into water, tirofiban is expected to adsorb to suspended solids and sediment based upon the estimated Koc. Volatilization from water surfaces is not expected to be an important fate process based upon this compound's estimated Henry's Law constant and estimated pKas. Tirofiban will exist as a zwitterion at pH values of 5 to 9 and therefore volatilization from water surfaces is not expected to be an important fate process. An estimated BCF of 3.2 suggests the potential for bioconcentration in aquatic organisms is low. Hydrolysis is not expected to be an important environmental fate process since this compound lacks functional groups that hydrolyze under environmental conditions. Occupational exposure to tirofiban may occur through inhalation and dermal contact with this compound at workplaces where tirofiban is produced or used. Exposure to the drug among the general population exposure may be limited to those individuals being administered tirofiban (an antithrombotic). (SRC) |
