Drug Development Preclinical Development and Testing

When a drug is developed its safety and efficacy has to be established to qualify for a licence to market it in Ireland – Irish Medicines Board or in the USA from the Food Drug Administration. The drug undergoes a series of tests to prove its medicinal ability is sufficient for the medicines market. Preclinical Development Preclinical testing performed by graduate researchers (Ph.D level), evaluate the medicines safety and efficacy before the medicine can be tested on humans. The medicine is rigorously tested for a 3-6 year period to assess its safety, biological activity, therapeutic ratio, and side effects in laboratory (in vitro) and on animals (in vivo). In vitro testing the drug is tested on cell cultures and isolated tissues. The concentration effect as are established. Pharmacological and toxicological effects are monitored. In vivo testing on two species of animal one rodent and non-rodent. Toxicological effects; mutagenicity, genotoxicity, teratogenic and carcinogenic are investigated. The lethal dose LD50 toxicity is defined. The dose-response relationship of the adverse effect is observed. Pharmacokinetics how the drug moves through living organisms, adsorption, distribution, metabolism and excretion are examined. The rate and amount of drug delivered to the blood and the dosage regimen to maintain therapeutically effective blood concentrations with little toxicity. What the body does to the drug when administered.

In preclinical research, scientists test their ideas for new biomedical prevention strategies in laboratory experiments or in animals. â€Å"Pharmacokinetics (PK) and pharmacodynamics (PD) can be seen as two sides of the same coin. PK and PD have a definite relationship, assessing how much drug gets to the site of action and then what that action is.

Sadly, clinical trials in oncology have the highest failure rate compared with other therapeutic areas. Given the high unmet need in oncology, it is understandable that barriers to clinical development may be lower than for other disease areas, and a larger number of drugs with suboptimal preclinical validation will enter oncology trials. HoweverRead MoreInvestigative New Drug Testing : Testing And Development Of New Drugs836 Words   |  4 PagesTesting and development of new drugs can be a long, strenuous and costly project for a manufacturing company. In 2003 drug companies spent $2.4 million on bringing new drugs to the market. By 2005 that figured ballooned to $802 million. If you think that is crazy, now experimental drugs cost pharmaceutical companies $312 million just for the post approval process of the drug and a whopping $2.9 billion to place the new drug on the market. The whole process can take 8-12 years until completion.Read MoreDrug And Drug Testing In The Roles Of The New Drugs831 Words   |  4 Pagesorder to get the approval process by the Unites States Food and Drug Administration before any drugs can be prescribed to any of it patients.

This model was intended to observe the daily bod change of each mouse in terms of body weight in relation to the development of the virus. This means that a mouse that presented severe illness or the body weight, loss of over 20% would be euthanized. After that a sample of its blood would be collected for further study.
