Therapeutic Modalities Flashcards
Health Def.
A dynamic state of wellbeing associated with physical, mental and social potential in relation to expectations associated with age, culture and personal responsibility
2 Views of Disease
Naturalistic and Normative
Naturalistic view of disease
condition interfering with organism’s natural state characterised by abnormal functioning of hosts one (or more) parts. Limited: Doesn’t take into account permanent (non-disease) conditions eg neurodivergence
Normative View
Any condition individuals/society views as harmful. Limited: corrupted by human influence. Eg: homosexuality
View of relationship between deviations from (perceived) average and disease today
No relation
3 Factors of Disease Today
Disvalue (normative), Phenomenology (naturalistic) and aetiology (cause)
Medicalising Conditions Def.
Treating conditions with medication unnecessarily
Therapeutic Modalities Aim
Minimise disvalue associated with disease
2 Types of Disease Disvalue
Morbidity (symptoms + disability) and Prognosis (probability of increased morbitity and chance of death
Lifestyle Drugs
Treatments for aspects of life that are not diseases but if alter would lead to perceived increase in quality of life
Bio-axisis
Demonstrates factors that impact health (probability of contracting disease). From genes to society (arrows on axsis pointing both directions)
Drug Therapuetics
Treatment on the patient (not societal) level. Used in disease alleviation/prevention. Very rarely cures
Measuring Individual Therapeutic Outcomes
Pharmacological (measures of chemical effects) and efficacy (desired therapeutic effect in controlled conditions)
Chemical Therapuetic Agent
Small molecule drug, peptide, antibodies, enzymes, vaccines and DNA product
Source of small molecules
Synthetic and natural
Peptide Source
Synthetic, natural and recombinant DNA
Antibodies Source
Natural (animal serum) and synthetic (mAb)
Enzyme source
Recombinant DNA
Vaccine source
Microorganisms and recombinant DNA
DNA Source
Recombinant DNA
Preclinical Study Steps
Research, novel chemical synthesis, test tube & animal testing, scale up synthesis (chronic animal results) and application for regulatory body approval
Clinical Studies Steps
Healthy human study, patient study, large clinical trial, Drug application to reglatory bodies and approval for marketing
Serendipity Def.
Beneficial development of events by chance
Constituents of Drug Chemical Structure
Group vulnerable to enzyme, pharmacophore (interacts with target protein) and carrier group (lipophilicity of molecules)
Druglikeness Def
Physicochemical properties of new chemical entities can determine efficacy of drug. LADME
Low therapuetic agents
Drug interacts highly with non-target area. higher risk then benefit
Toxicity Def.
Degree to which substance causes damage in body eg side effects, adverse reaction and death
Drug Screening Outline
High-throughput (1000), hit to lead (100), lead optimilisation (dozens), candidate seeking (1-3) and precilinical development
Overlap between ideal drug and conventional therapeutic Drugs
Patient acceptability, industry choice and side effects
