Physical and Chemical Properties of Matter

The characteristics that enable us to distinguish one substance from another are called properties. Physical Properties of Matter A physical property is a characteristic of matter that is not associated with a change in its chemical composition. Familiar examples of physical properties include density, color, hardness, melting and boiling points, and electrical conductivity. We can observe some physical properties, such as density and color, without changing the physical state of the matter...

Therapeutic Index

The therapeutic index of a drug is a key parameter in pharmacology that quantifies the relative safety of a drug by calculating the ratio between the dose that causes toxicity in half the population (50%) to the dose that proves to be effective for half the population (50%). It provides a spectrum of doses for a particular drug ranging from effective to potentially toxic. To illustrate, consider an anticoagulant agent like warfarin. It possesses a narrow window within its therapeutic index to...

Properties of Transition Metals

Transition metals are defined as those elements that have partially filled d orbitals. As shown in Figure 1, the d-block elements in groups 3–12 are transition elements. The f-block elements, also called inner transition metals (the lanthanides and actinides), also meet this criterion because the d orbital is partially occupied before the f orbitals. Figure 1: Periodic Table. The transition metals are located in groups 3–11 of the periodic table. The inner transition metals are in the two rows...

Source: Laboratory of Alan Lester - University of Colorado Boulder The physical properties of minerals include various measurable and discernible attributes, including color, streak, magnetic properties, hardness, crystal growth form, and crystal cleavage. These properties are mineral-specific, and they are fundamentally related to a particular mineral’s chemical make-up and atomic structure. This video examines several physical properties that are useful in field and hand sample mineral...
FAQs
Efficacy describes the maximum beneficial effect a drug can produce, whereas potency indicates the amount needed to produce a given effect. A highly potent compound is not necessarily more effective if its maximum response is limited. Pharmacologists assess both characteristics to compare candidate substances, interpret dose-response relationships, and determine whether a treatment can achieve a clinically useful outcome.
Selectivity reflects how preferentially a compound interacts with its intended receptor, enzyme, ion channel, or transporter rather than other molecular targets. Greater selectivity can help focus the desired cellular response, while unintended interactions may contribute to adverse effects. Comparing target interactions therefore helps pharmacologists evaluate a compound’s likely benefits, limitations, and safety profile.
Dose determines the exposure available to produce a biological response, while duration of action describes how long that response persists. An appropriate dose must support efficacy without creating unacceptable adverse effects, and the useful duration depends on the treatment goal. These variables guide dose optimization and help balance sustained benefit against potential risk.
Evaluation combines assessment of beneficial effects with measurements of efficacy, potency, selectivity, duration of action, and safety. Investigators relate observed responses to the compound’s interaction with molecular targets and to the dose used. This integrated analysis helps distinguish promising activity from responses that may be too weak, short-lived, nonspecific, or associated with unacceptable adverse effects.
During drug discovery, therapeutic properties help identify compounds whose molecular actions could produce useful physiological responses. Candidate substances can then be compared according to efficacy, potency, selectivity, duration, and safety. This information supports decisions about which compounds warrant further development and highlights areas requiring optimization before a treatment can be considered clinically useful.
Clinical pharmacology uses these characteristics to support treatment selection, dose optimization, and assessment of expected benefits and risks. Efficacy informs whether a therapy can address a disease-related goal, while potency, duration, selectivity, and safety influence how it may be used. The same framework also supports evaluation of substances intended for disease prevention, diagnosis, management, or treatment.
