What are the pharmacokinetics: (Timolol, 2015) a. Use – Beta-blocker, migraine/headache, prevention of further MI (Lexicorp, 2015) b. Mechanism of action – non-selectively antagonizes beta-1 and beta-2 adrenergic receptors c. Well absorbed when given orally (Woo & Wynne, 2012). d. Metabolizes in the liver, CYP450, 2D6 substrate e. Excretion – urine f. Half-life 2 – 4 hours 3. What are the pharmacodynamics: a.
Here is what I had said for the Topamax and Mary’s headache 7. The Topamax is causing the acid-base disturbance and her respiratory system is attempting to compensate through hyperventilation to decrease H+ and bring her pH up. The H+ however is increasing because the Topamax is causing the renal carbonic anhydrase to redirect HCO3- out of the body and retain H+. 8. B: Ingestion of an acidifying drug in this case is to blame.
_____ Glucagon acts by raising blood sugar levels; insulin acts by lowering blood sugar levels. 46. _____ Secretin is released by the small intestine due to the presence of acid and leads to bicarbonate release from the gall bladder. 47. _____ CCK is released by the stomach due to the presence of fats and leads to bile release from the pancreas.
a. By inhibiting the pituitary secretion of anti-diuretic hormone (ADH), alcohol also affects urine excretion. ADH acts on the kidney to reabsorb water, so when it is inhibitted, ADH levels drop, the kidneys don't reabsorb as much water and the kidneys produce more urine. b. Alcohol, once consumed, enters the bloodstream and causes the pituitary gland in the brain to block the creation of vasopressin.
Aldolase B is considered the chief aldolase isoenzyme that is responsible for fructose metabolism and gluconeogenesis within the liver. This is turn, produces fructose 1,6-biphosphate from the glyceraldehyde-3-phosphate and dihydroxyacetone phosphate. When fructose is ingested, the body cannot change its energy storage substance glycogen to glucose. When glucose builds up in the liver, the blood sugar falls resulting in hypoglycemia. (PubmedHealth, 2009) Fructose 1 phosphate which is the substrate of Aldolase B is split by Aldolase.
Caffeine & Alcohol Effect on the Water Flea Heart Rate Abstract In this study, water fleas (Daphnia magna), a semi-transparent freshwater crustacean, are used to study the effects of caffeine and alcohol on heart rate. There was a control group used along with the alcohol and caffeine to ensure the results were more accurate. The prediction was the introduction of alcohol and each increased concentration of alcohol, would decrease heart rate and the introduction and subsequent increased concentrations of caffeine would increase heart rate. The results of this experiment proved the prediction to be correct with the alcohol, but the results from the caffeine were hardly noticeable. Methods & Materials
25- metabolism is also referred to as biotransformation because it involves the biochemical alteration of a drug into an inactive metabolite. LIVER IS INVOLVED IN METABOLISM. Pg. 38- Pediatrics 1. Gastric ph is less acidic because acid producing cells in stomach are immature until approx.
hCG effects the hormone LH (Luteinizing hormone) and the target tissue is the ovaries in women and testis in men. Symptoms of hCG include morning sickness, Hyperthyroidism, and Ovarian Hyperstimulation Syndrome. Raised hGC levels can cause multiple fetuses, Hydatidiform Mole, and Choriocarcinoma. You can receive hCG injections or orally to correct you hCG level. Cushing’s disease is a condition where the pituitary gland releases too much adrenocorticotropic (ACTH).
Methylphenidate the active ingredient in Ritalin attaches to this pump and blocks it making more dopamine available in the cleft for the signal-receiving neuron. Adderoll and other amphetamines enter the dopamine-producing neuron through the pumping mechanism and push dopamine out of the cell and into the synaptic cleft increasing the amount of dopamine available to act on the dopamine-receiving
