Module 1

 

First pass effect: reduces the bioavailability of drug to less than 100%. esp drug absorbed PO. drugs given by IV has 100% bioavailability.

all drug that is absorbed by the intestine must first pass through the liver before it reaches the systemic circulation

Therapeutic index and Dosage range: ratio between the toxic and therapeutic concentration of a drug.

a drug with low therapeutic range have the likelihood of causing adverse reaction therefore need close monitoring. e.g wafarin and digoxin than amoxicillin

Peak and Trough level (Indicated drugs): describes drug concentration. its measured with blood sample.

peak: time required for the drug to reach its maximum therapeutic response. highest blood level

trough: lowest blood level.

if the peak level if too high; this means toxicity.

Sympathetic Nervous System: couterpart of the parasympathetic system. they both make up the autonomic nervous system in which it creates a check and balance system for maintaining the normal homeostasis of the autonomic functions of the human body.

Alpha and Beta receptors

  • alpha adrenergic agonist response is vasoconstriction and CNS stimulation.

  • Alpha1 located in the postsynaptic effector cells

  • Alpha2 located at the presynaptic nerve terminals- control the release of neurotransmitters.

  • Beta adrenergic agonist response results in bronchial, GI and uterine smooth muscle relaxation; glycogenolysis and cardia stimulation.

  • Beta adrenergic receptor are located in the postsynaptic effector cells

  • Beta 1 adrenergic are located primarily in the heart

  • Beta 2 located in the smooth muscle fibers of the bronchioles, arterioles and viseral organ.

  • Beta 3: located in the human urothelium muscle and detrusor muscle

  • Cardiovascular system

Blood vessel- alpha 1- vasoconstriction

  • beta 2- vasodilation

cardia muscle- beta 1- increases contractility

AVnodes- beta 1- increase HR

SA node- beta1- increase HR

  • Endocrine

liver- alpha1 and beta 2 -glycogenesis

Kidney- beta 1 - increase renin secretion

Gastrointestinal

muscle- alpha 1 and beta 2-decrease motility

  • Genitourinary

bladder sphincter- alpha 1- contriction

penis- alpha 1- ejaculation

Uterus- alpha 1- contraction

  • beta 2- relaxation

adrenergic drugs (catecholamines) : similar to or mimic the effects of the SNS. three neurotransmitter classified as catecholamines are epinephrine, noepinephrine and dopamines. Produce a sympathomimetic response

Catecholamines are produced by the SNS and are stored in the vesicles or granules located in the ends of the nerves

they can either be endogenous which are epinephrine, noepenephrine or dopamine or synthetic substance which is the dobutamineand phenylephrine.

Catecholemines are metabolized by 2 enzymes,es MOA and COMT

  • MOA breaks down catecholamines at the nerve ending while the COMT breaks it down in the synaptic cleft

Posititve iotropic effect: increase the force of contraction

Positive chronotropic effect: increase HR

Positive dromotropic effect: increase conduction of the cardiac electric nerve impulse through the AV node.
