What pregancy category has shown an adverse effect of animal reproduction but there are no adequate and well controlled studies in humans.
What category is there POSITIVE evidence of fetal risk based on adverse reaction date from investigational or marketing experience or studies in humans. Potential benefits may warrant use of drugs in women tho. Derp
What category do studies in humans and animals have demonstrated fetal abnormalities and there is fetal risk and the risks involved in the use of the drug in pregnant women CLEARLY outweigh the potential benefits

What type of medical administration route goes through the GI tract?
What type of medication goes outside the GI tract?
The parameters that determine a drugs duration and intensity are divided into what four processses
Absorption, distribution, biotransformation/metabolism and elimination
The rate of absorption is dependent on what?
The drug concentration gradient, thickness of barrier and surface area available
The movement from general circulation through tissues to the site of action is?
The concentration of a drug at a target site is dependent on what
The volume of the body receiving it (volume of distribution) and the amount of drug given.
Volume of distribution may be increased by what ?
Decreased by what?
Renal failure and liver failure
What processes decrease blood concentration?
Where does the vast majority of metabolism take place.
How does it prepare a substance to be eliminated
Enzymes (metabolic pathways) to cause a chemical reaction that prepares the organic/chemical substance to be eliminated
Where is the elimination of toxic or inactive metabolites, primarily done?
Drugs are eliminated through that processes?
Active Tubular Secretion
Passive Tubular Reabsorption
Describe absorption in the skin of a child
Better perfusion and hydration, thinner stratum corneum
Describe intramuscular absorption in children
Decreased muscle mass and immature vasculariy
Describe GI absorption in children
Slower paristalsis (more time for absorption)
Immature digestive system (but approaches adult values by 6-12 months)
Describe water content in the body of a child pertaining to medications
Increased water content which causes increased distribution
Describe blood composition in pediatric patients
Smaller amounts of albumin, more unbound drug and increased distribution
This increases drug concentration
Describe changes in pediatrics for metabolism in drugs?
Enzymes in the bodyy are not developed (reduced metabolism)
6-12 months they have an increased metabolism
Describe changes in pediatrics in regards to differences in elimination during drugs
Glomerular Filtration Rate is .5 adult values at birth and the pediatric nephrons dont become fully functional until 1 year
Less frequent dosing may be needed to avoid toxicity
