| Rt | right; total resistance |
|---|---|
| RTF | resistance transfer factor; respiratory tract fluid |

| drug psychosis | Psychosis following or precipitated by ingestion of a drug, e.g., LSD. (05 Mar 2000) |
|---|---|
| drug rash | Adverse cutaneous reactions caused by ingestion, parenteral use, or local application of a drug. These may assume various morphologic patterns and produce various types of lesions. (12 Dec 1998) |
| drug residues | Drugs and their metabolites which are found in the edible tissues and milk of animals after their medication with specific drugs. This term can also apply to drugs found in adipose tissue of humans after drug treatment. (12 Dec 1998) |
| drug resistant | Unresponsive to the desired effects of drugs or other therapy for example: irradiation cytotoxic agents or hormones. Drug resistance of cells within tumours is probably the major cause of treatment failure. (16 Dec 1997) |
| drug screening | Preclinical testing of drugs in experimental animals or in vitro for their biological and toxic effects and potential clinical applications. (12 Dec 1998) |
| drug screening assays, antitumour | Methods of investigating the effectiveness of anticancer cytotoxic drugs and biologic inhibitors. These include in vitro cell-kill models and cytostatic dye exclusion tests as well as in vivo measurement of tumour growth parameters in laboratory animals. (12 Dec 1998) |
| drug side effect | An often undesirable effect that occurs in association with the use of a particular medication. Examples of common drug side effects include: nausea, vomiting, sedation, dizziness, headache and weakness. Drug side effects that occur in 1% or more, of patients taking a particular medication are considered to be causally related to the use of that medication. (27 Sep 1997) |
| drug tetanus | Tonic spasms caused by strychnine or other tetanic. Synonym: toxic tetanus. (05 Mar 2000) |
| drug therapy, combination | Drug therapy with two or more drugs given separately for a combined effect. (12 Dec 1998) |
| drug therapy, computer-assisted | Adjunctive computer programs in providing drug treatment to patients. (12 Dec 1998) |
| drug, tocolytic | A medication that can inhibit labour, slow down or halt the contractions of the uterus. Tocolytic agents are widely used today to treat premature labour and permit pregnancy to procede and so permit the foetus to gain in size and maturity before being born. (12 Dec 1998) |
| drug tolerance | Progressive diminution of the susceptibility of a human or animal to the effects of a drug, resulting from its continued administration. It should be differentiated from drug resistance wherein a human, animal, disease, or tissue fails to respond to the intended effectiveness of a chemical or drug. (12 Dec 1998) |
| drug toxicity | The systemic effects of a drug that are related to the overall level of the medication in the bloodstream. Drug toxicity may occur with overdosage of a medication, accumulation of the drug in the body over time or the inability of the patients body to eliminate the drug. (27 Sep 1997) |
| drug utilization | The utilization of drugs as reported in individual hospital studies, FDA studies, marketing, or consumption, etc. This includes drug stockpiling, and patient drug profiles. (12 Dec 1998) |
| drug utilization review | Formal programs for assessing drug prescription against some standard. Drug utilization review may consider clinical appropriateness, cost effectiveness, and, in some cases, outcomes. Review is usually retrospective, but some analysis may be done before drugs are dispensed (as in computer systems which advise physicians when prescriptions are entered). Drug utilization review is mandated for medicaid programs beginning in 1993. (12 Dec 1998) |
