Food = 20 percent of total fluid intake, so if you consume 2 L of water or other beverages a day ( a little more than 8 cups) along with your normal diet, you will typically replace lost fluids |

Water Imbalance: Hyperemesis gravidarum |
|
Definition
Pregnancy-related unrelenting, excessive nausea/vomiting that prevents adequate intake of food or fluids. However, recent research in fetal programming indicates that prolonged stress, dehydration and malnutrtition during pregnancy can put the fetus at risk for chronic disease, such as diabetes or heart disease, later in life, or neurobehavioral issues from birth. This underscores the importance of aggressive treatment of the condition. |

Definition
a compound that, on administartion, must undergo chemical conversion by metabolic processes before becoming an active pharmacological agent; a precursor of a drug. Reactant: ester cleavage of prodrug, ceftin |

Term
|
Definition
poor bioavailabilities (fraction of drug absorbed, compared to IV route) when given orally. Esterification permits passive diffusion across the gut wall by reducing polarity. After passing into circulation, ester hydrolysis is required to convert drug to active form. Success factors: solubility, lipophilicity, and stability to chemical or enzymatic degradation. Cephalosporin esters are = 50% bioavailability. Premature hydrolysis in the gut reduces fraction absorbed. Active drug in the gut may change balance of gut flora, causing diarrhea and other effects. |

|
Definition
Drug product stability, hydrolysis degradation. Drug release from solid dosage form to liquid (phase transition) prior to absorption and therapeutic action. During manufacture, water facilitates drug product creation. |
