Description

This standard operating procedure outlines the handling and use of rapamycin. Review this document and supply the information required in order to make it specific to your facility. In accordance with this document, laboratories should use appropriate controls, personal protective equipment, and disposal techniques when handling rapamycin.

Rapamycin is an immunosuppressant drug used to prevent rejection in organ transplantation; it is especially useful in kidney transplants. Rapamycin is not a calcineurin inhibitor. However, it has a similar suppressive effect on the immune system. Rapamycin inhibits the response to interleukin-2 (IL-2) and thereby blocks activation of T- and B-cells. The health effects from long-term usage could include increase the risk of developing an infection or cancer, especially lymphoma (cancer of a part of the immune system) or skin cancer.

Synonyms: RAPA, RPM, Rapamune, Sirolimus, "macrocyclic polyketide", "macrocyclic triene antibiotic", antirestenotic, immunosuppressant, "mTOR inhibitor"

Potential Hazards

• Toxic: danger of serious damage to health by prolonged exposure if swallowed.
• Possible carcinogenic effect.
• Biologically active compounds may produce idiosyncratic effects which are entirely unpredictable on the basis of literature searches and prior clinical experience (both recent and past).
• Ingestion of the material may be damaging to the health of the individual.

Macrolides comprise a large group of antibiotics derived from Streptomyces spp. having in common a macrocyclic lactone ring to which one or more sugars are attached. They are all weak bases. The most common side effect produced by the family of macrolide antibiotics is gastrointestinal discomfort. Supra-infections may occur although these are rare. Several macrolides produced allergic sensitization but, again, these are rare. Symptoms include watery eyes, shortness of breath, nasal congestion, choking, coughing and wheezing. Allergic skin reactions have also occurred. Exposure to at least one member of the family, erythromycin, at high concentrations, has produced reversible deafness (ototoxicity). Systemic reactions including fever, rash, and lymph-node pain or swelling have been produced by the avermectin group. Ivermectin has produced ataxia (incoordination), lethargy, bradypnea (slowed breathing), vomiting, mydriasis (dilated pupils), sedation, tremors and death in animals. The avermectin group (anthelmintics, insecticides and acaricides) mediate the transmission of gamma-butyric acid (GABA), an inhibitory neurotransmitter, in mammals thus causing paralysis. Hepatotoxic effects with transient disturbances and jaundice have resulted from the use of oleandomycin. Transient alterations in heart rate/ rhythm have also been produced by several members of the family (notably tilmicosin). Heart muscle degeneration, characterized by small areas of cell death has also been reported in animals exposed to tilmicosin. Cross-resistance is often observed between the macrolide, lincosamide and streptogramin group of antibiotics.

Eye: Although the material is not thought to be an irritant, direct contact with the eye may cause transient discomfort characterized by tearing or conjunctival redness (as with windburn). Slight abrasive damage may also result. The material may produce foreign body irritation in certain individuals.

Skin: The material is not thought to produce adverse health effects or skin irritation following contact (as classified using animal models). Nevertheless, good hygiene practice requires that exposure be kept to a minimum and that suitable gloves be used in an occupational setting.

Open cuts, abraded or irritated skin should not be exposed to this material. Entry into the blood-stream through, for example, cuts, abrasions or lesions, may produce systemic injury with harmful effects. Examine the skin prior to the use of the material and ensure that any external damage is suitably protected.

Inhaled: The material is not thought to produce either adverse health effects or irritation of the respiratory tract following inhalation (as classified using animal models). Nevertheless, adverse effects have been produced following exposure of animals by at least one other route and good hygiene practice requires that exposure be kept to a minimum and that suitable control measures be used in an occupational setting.

Persons with impaired respiratory function, airway diseases and conditions such as emphysema or chronic bronchitis, may incur further disability if excessive concentrations of particulate are inhaled.

Engineering Controls

• Enclosed local exhaust ventilation is required at points of dust, fume or vapor generation.
• Work should be performed in a fume hood or Biological Safety Cabinet.

Work Practice Controls

Decontamination should consist of surface cleaning with water and detergent followed by thorough rinsing. The use of detergent is recommended because there is no single accepted method of chemical deactivation for all agents involved. A plastic backed absorbent pad should be placed under the work area during the process. This should be changed at the end of each procedure or when a spill occurs.

Personal Protective Equipment (PPE)

Personal protective equipment includes a lab coat, eye protection and disposable gloves.  Gloves should be changed frequently and should be pulled up over sleeves if possible to reduce the likelihood of any exposed skin. Wash hands and arms immediately after working with the substance. Particulate respirator protection should be assessed where incidental or accidental exposure is anticipated.

Note: Respirators are masks designed to protect the wearer from specific airborne hazards and are different from surgical masks, which protect the wearer only from splashes and are primarily intended to protect others from infectious aerosols exhaled by the wearer. Respirator use requires employee participation in the Respiratory Protection Program, which involves medical clearance and annual fit testing and training. Please be clear about use of surgical masks versus respirators. (Do NOT use the vague term “masks”.)

Transportation and Storage

• Keep containers tightly closed and store in a dry and ventilated area.
• Store away from strong oxidizing agents.
• Store according with information on product insert.
• Rapamycin is NOT REGULATED by DOT or IATA.

Waste Disposal

All hazardous chemical agent contaminated waste should be placed in a 5 gallon white pail. The container should be closed except when actively adding waste. The container must be located in the area where hazardous drugs are being used. All items contaminated by hazardous drugs, including gloves, syringes, vials needles, and solution containers should be disposed according to OSEH guidelines.

Sharps – place needles, syringes with needles attached and other breakable items into appropriately labeled sharps containers.

Empty stock vials, reagent bottles, etc. – triple rinse with copious amounts of water. Deface label with black magic marker or scraper. Place in a cardboard box for disposal.

Because most spent, unused and expired chemicals/materials are considered hazardous wastes, they must be properly disposed of. Do not dispose of chemical wastes by dumping them down a sink, flushing in a toilet or discarding in regular trash containers, unless authorized by OSEH Hazardous Materials Management (HMM).Bold text Contact OSEH-HMM at (734) 763-4568 for waste containers, labels, manifests, waste collection and for any questions regarding proper waste disposal. Also refer to OSEH’s Hazardous Waste webpage for more information.

If animals are administered rapamycin in their food or water, both the food and water container must be labeled.  Food or water that is not consumed by the animals must be collected, labeled and submitted for disposal as a hazardous material.

Exposures/Unintended Contact

If the employee is in need of emergency medical attention, call 911 immediately.

SWALLOWED

• Seek medical advice.
• Give water to rinse out mouth.
• If swallowed do NOT induce vomiting, unless directed to do so by medical personnel.
• If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain open airway and prevent aspiration.

EYE

If this product comes in contact with the eyes:

• Wash out immediately with fresh running water.
• Ensure complete irrigation of the eye by keeping eyelids apart and away from eye and moving the eyelids by occasionally lifting the upper and lower lids.
• If pain persists or recurs seek medical attention.
• Removal of contact lenses after an eye injury should only be undertaken by skilled personnel.

SKIN

If skin or hair contact occurs:

• Flush skin and hair with running water (and soap if available).
• Seek medical attention in event of irritation.

INHALED

• If inhaled remove from contaminated area.
• Consult a physician.

Contact OSEH for advice on symptoms of chemical exposure, or assistance in performing an exposure assessment.

Spill Procedure

• When a spill occurs, personal safety should always come firstItalic text. • Alert and clear everyone in the immediate area where the spill occurred.

A minor (small) chemical spill is one that the laboratory staff is capable of handling safely without the assistance of safety and emergency personnel. A major/large chemical spillItalic text requires active assistance from emergency personnel.

Spill Response Steps:

MINOR CHEMICAL SPILL

• Alert people in immediate area of spill.
• Open outside windows, if possible.
• Use proper personal protective equipment (PPE) as indicated above.
• Avoid breathing vapors from spill.
• Confine spill to as small an area as possible.
• Do not wash spill down the drain.
• Use appropriate spill kits/sorbents to absorb spill. Collect contaminated materials and residues and place in container. For powdered chemicals sweep carefully to avoid generation of dust or, if appropriate, use moist sorbent pads or wet the powder with a suitable solvent and then wipe with a dry cloth. Contact OSEH-HMM (734) 763-4568 for proper disposal.
• Clean spill area with water.

MAJOR CHEMICAL SPILL

• Attend to injured or contaminated persons and remove them from exposure.
• Alert people in the laboratory to evacuate.
• If spilled material is flammable, turn off ignition and heat sources. Don’t light Bunsen burners or turn on other switches.
• Call University of Michigan Division of Public Safety and Security (DPSS) at 911 immediately for assistance.
