  Immunosuppressant Drugs - Definition, Purpose, Description, Recommended dosage, Precautions, Side effects, Interactions
Immunosuppressant drugs, which are also called anti-rejection drugs, are used to prevent the body from rejecting a transplanted organ.
People taking immunosuppressant drugs should avoid contact with anyone who has had a recent dose of oral polio vaccine, as there is a chance that the virus used to make the vaccine could be passed on to them.
Immunosuppressant drugs are also associated with a slightly increased risk of cancer because the immune system plays a role in protecting the body against some forms of cancer.

 Treatments: Immunosuppressive drugs - WrongDiagnosis.com
Immunosuppressants are usually longer-lasting drugs and work in a different manner, usually by interfering with the body's white blood cells (T-cells or B-cells).
Unfortunately, modern immunosuppressants are not specific and suppress all of the immune system, leaving the patient vulnerable to a variety of opportunistic infections that would normally be prevented by the immune system.
Immunosuppressants are given to transplant patients to prevent organ rejection and to patients with autoimmune diseases like lupus.

  Immunosuppressive drug - Wikipedia, the free encyclopedia
Immunosuppressive drugs or immunosuppressants are drugs that are used in immunosuppressive therapy to inhibit or prevent activity of the immune system.
The immunosuppressive drugs also interact with other medicines and affect their metabolism and action.
The drug is used particularly in the liver and kidney transplantations although in some clinics it is used in heart, lung and heart/lung transplants.

 Immunosuppression - Wikipedia, the free encyclopedia
Immunosuppression is the medical suppression of the immune system.
To prevent that, radiation therapy was used in the past, but now immunosuppressant drugs are used to inhibit the reaction of the immune system.
Immunosuppression is also used to counteract autoimmune diseases, such as rheumatoid arthritis or Crohn's disease, to prevent the immune system from attacking healthy parts of the body.

 New treatments show promise for some diabetics   (Site not responding. Last check: 2007-10-31)
Doctors have tried immunosuppressant drugs to slow type 1 diabetes, but the treatments were too toxic for patients to use long term.
In addition to testing drugs that keep transplant recipients from rejecting new organs, they are studying therapies used for other autoimmune diseases such as rheumatoid arthritis, and new uses for insulin itself.
The hope is that the drugs will prevent diabetics' immune systems from attacking and killing insulin-producing beta cells in the pancreas, just as they prevent a transplant patient from rejecting a new heart or kidney.

 [No title]
Anti-convulsant drugs: The term anti-epileptic is used synonymously with anti-convulsant to describe drugs that are used to treat epilepsy (which does not necessarily cause convulsions), as well as non-epileptic convulsive disorders.
Drugs that reduce the duration and spread of electrically induced convulsions in animal models are generally effective in controlling other types of epilepsy (such as tonic-clonic seizures).
Mechanisms of action of anti-convulsant drugs: Two main mechanisms appear to be important in the action of anticonvulsant drugs: Enhancement of GABA action: Phenobarbital and benzodiazepines enhance the activation of GABAA receptors, thus facilitating the GABA-mediated opening of chloride channels.

 Drug substitution in Transplantation
Drug substitution may involve the substitution of one generation of a drug for another, the use of a different agent within the same class of drugs or the use of a generic formulation for a brand name product.
A conference on "Drug Substitution in Transplantation" was organized by the NKF in April 1998 to review the recent literature and to develop recommendations for the safe and effective use of generic immunosuppressant medications in solid organ transplant recipients.
For critical-dose drugs, replicate design studies to determine intrasubject variability and subject-by-formulation interaction should be required as part of the approval process for both innovator drugs and their generic counterparts.'' The application of the recently proposed changes in the FDA bioequivalence metric would satisfy these requirements.

 Future Directions   (Site not responding. Last check: 2007-10-31)
Immunosuppressant drugs are the most commonly used method to eliminate rejection after transplantation.
There are many kinds of such drugs that involve different mechanisms in the human body, but many of them have side effects due to ubiquitous targets.
Some of the future possibilities of immunosuppressant drugs include tailoring of the drugs on the genetic basis of the patient, and developing the method to withdraw the drugs not only to eliminate complications caused by remaining drugs, but also to reduce high costs (Denton, 1999).

 FDA press release
The Food and Drug Administration has asked the makers of corticosteroid drugs to warn doctors that the long-term or high-dose treatment with these products may place patients exposed to chicken pox or measles at increased risk of unusually severe infections or even death.
Corticosteroids are drugs commonly prescribed and used in children to treat a variety of chronic conditions such as asthma, allergies, and juvenile arthritis.
Immunosuppression has been reported with different doses and treatment lengths but, most often, problems occur with either low-dose prolonged treatment or with moderate - to high - dose treatments of varying durations.

 Cancer News - CancerConsultants.com
Immunosuppressant drugs, such as methotrexate and cyclosporine, are used after an allogeneic SCT to prevent the development of graft-versus-host disease (GVHD), a condition that develops after allogeneic SCT in some persons whose bodies have difficulty accepting the donor stem cells as their own.
However, immunosuppressant drugs are also associated with a higher risk of a cancer relapse after treatment.
The challenge then is to give just enough immunosuppressant drugs to prevent life-threatening GVHD but to avoid a great increase in the risk of later cancer relapse.

Immunosuppressants (or immunosuppressant drugs) are given to all patients after a heart transplantation.
The main side effect of this drug is that it may reduce the production of cells in the marrow by too much, and this dramatically increases the risk of infection or bleeding.
Some antibiotics interact with the immunosuppressants and in general they should only be given either by the transplant centre or after discussion with the medical staff there.

 Pancreas-Kidney Transplantation: Drugs
This drug, like the others, must be used in combination with other drugs to suppress several actions of the immune system.
Since several of the required immunosuppressants may cause hypertension, blood pressure medication may be required, although calcium-channel blockers like Cardizem and Procardia can propitiate the bioavalability of some immunosuppressants, requiring a smaller dose to acheive the same blood level.
Compliance with your drug regime, long-term, is perhaps the single most important facet in maintaining the health of the transplants.

 Drug-drug interactions of antivirals, immunosuppressants and immunizations
Antiviral and immunosuppressant drugs are being used increasingly more often in children, and because many of these drugs interact with many other commonly used drugs, it is imperative that clinicians become familiar with these interactions, and their clinical significance.
Drugs commonly used in the pediatric population whose hepatic metabolism may be inhibited include benzodiazepines (e.g., midazolam), opiate analgesics, cisapride, astemizole, and glucocorticoids.
Drugs that may induce the hepatic metabolism of the antiretrovirals (and thus potentially reduce their efficacy) include rifampin (Rifadin, Rifamate, Rifater, Hoechst Marion Roussel) and rifabutin (Mycobutin, Pharmacia and Upjohn), various anticonvulsants (e.g., phenobarbital, phenytoin [Dilantin, Parke-Davis], carbamazepine), and dexamethasone.
