Q

Excretion

A

The process of eliminating or expelling waste matter.

32
Q

First-Order Elimination

A

A mechanism of clearance in which a constant amount of a drug is eliminated per unit of time.

33
Q

Zero-Order Elimination

A

A mechanism of clearance in which a drug undergoes a constant process of elimination regardless of the plasma concentration of the drug.

34
Q

Pharmacodynamics

A

The study of a drug’s molecular, biochemical, and physiologic effects or actions on the body.

35
Q

Direct Effects

A

A mechanism of drug action in which the result of a drug interacting with a receptor enzyme is central to the pathway of that effect.

36
Q

Indirect Effects

A

A mechanism of drug action in which the result of a drug interacting with receptor proteins of other biologic structures are significantly upstream from the end biochemical process that produces the drug effect.

37
Q

Immediate Effects

A

A mechanism of drug action in which the effects of the drug are immediate after administration.

38
Q

Delayed Effects

A

A mechanism of drug action in which the effects of the drug are delayed after administration.

39
Q

Spare Receptors

A

Receptors that exist in excess of those required to produce a full effect of a medication.

40
Q

Acetylcholine Receptors

A

A membrane protein that responds to the binding of acetylcholine, a neurotransmitter.

41
Q

Muscarinic Receptors

A

Acetylcholine receptors that form G protein-coupled receptor complexes in the cell membranes of the parasympathetic nervous system. When muscarinic receptors are activated by acetylcholine, a parasympathetic response follows.

42
Q

Nicotinic Receptors

A

Acetylcholine receptors in the cell membranes of the sympathetic nervous system.

43
Q

Steroid Receptor

A

A class of molecules that function as both a receptor that converts physical energy into electric voltage, or current, and one that passes an impulse from one place to another.

44
Q

Catecholamines

A

Dopamine, norepinephrine, and epinephrine that act as both neurotransmitters and hormones to maintain homeostasis through the autonomic nervous system with affinity for adrenergic receptors.

45
Q

Agonist

A

Drugs with both affinity (ability to bind to the target receptor) and intrinsic efficacy (produce a response by changing receptor activity).

46
Q

Partial Agonist

A

Drugs that reduce the efficacy of other agonist chemicals.

47
Q

Antagonist

A

Drugs that bind to a receptor either on the primary site or on another site which stops the receptor from producing a response all together.

48
Q

Drug-Enzyme Interactions

A

Drugs bind enzymes and cause change in their activity.

49
Q

Non-Specific Drug Binding

A

Binding at molecular sites not designed as receptors which prohibit the drug from binding to the actual receptor, therefore inactivating the drug.

50
Q

Affinity

A

A measure of how avidly a drug binds to a receptor.

51
Q

Efficacy

A

A measure of the magnitude of the effect once the drug is bound.

52
Q

Potency

A

A measure of the quantity of the drug needed to produce the maximal effect.

53
Q

Potentiation

A

When one drug does not elicit a response to another drug

54
Q

Addivity

A

When the effect of two drugs given in combination equals the mathematical summation of their effects when given alone.

Q

Synergism

A

When the combined effect of two drugs is greater than the sum of their effects when given separately.

58
Q

FDA Categorization of Drugs for Use in Pregnancy - C

A

There have been some adverse effects noted through animal studies but the benefits of administering the medication outweigh the risks.
