An overview of pharmacology

Jump to navigation Jump to search Basics of Pharmacology[ edit ] Understanding how the science of pharmacology works will help us understand questions like, "How come a person's stomach burns after taking an aspirin tablet? However, the active ingredient of crude drugs are not purified and the substance is adulterated with other substances. After the liver enzymes are completed on the medicine, the now inactive drug goes trough the final stage of the body known as excretion. These steps occur mainly in the body's chemical processing plant known as the liver. This is important because the protein and fat molecules can latch onto the drug molecules and essentially stop the progress of the drug. The things that are taken into the bloodstream regardless of how it was taken in in the first place, is transported to the this large internal organ. This is when the bloodstream transports the medicine throughout the body. Psychopharmacology , is the study of the effects of drugs on the psyche , mind and behavior,[ citation needed ] such as the behavioral effects of psychoactive drugs. It needs to be determined how safe the medicine is for human consumption, its stability in the human body and the best form for delivery to the desired organ system, like tablet or aerosol. Indapamide has a dual mechanism of action: diuretic effect at the level of the distal tubule in the kidney and a direct vascular effect, both of which contribute to the antihypertensive efficacy of the drug. Indapamide SR has now been extensively used in hypertensive patients, including those at increased risk, for example elderly or diabetic patients.

For example, a pain reliever used for the purpose of calming down a sore leg may result in irritating the stomach. This barrier is designed from an extremely compact and tight woven mesh of capillaries packed together as a defence wall against harmful and deadly substances like poisons or viruses.

Pharmacology drugs

Some of these enzymes break down molecules. Pharmacology is immensely important for treating diseases and how medicine affects the organs of the body. The major systems studied in pharmacology can be categorised by their ligands and include acetylcholine , adrenaline , glutamate , GABA , dopamine , histamine , serotonin , cannabinoid and opioid. This is important because the protein and fat molecules can latch onto the drug molecules and essentially stop the progress of the drug. July Learn how and when to remove this template message Drug discovery is the field of study concerned with creating new drugs. In the European Union , the main body that regulates pharmaceuticals is the EMA and they enforce standards set by the European Pharmacopoeia. The SR formulation contains a hydrophilic matrix, which delivers a smoother pharmacokinetic profile. These include neuropharmacology , in the central and peripheral nervous systems ; immunopharmacology in the immune system. After the liver enzymes are completed on the medicine, the now inactive drug goes trough the final stage of the body known as excretion. The liver has many chaotic events and activity going on but it is very controlled activity. Dose response curves are studied extensively in pharmacology The study of chemicals requires intimate knowledge of the biological system affected.

High systolic blood pressure SBP may be the main parameter involved in cardiovascular morbidity and mortality. Clinical pharmacology is the basic science of pharmacology focusing on the application of pharmacological principles and methods in the medical clinic and towards patient care and outcomes.

pharmacy profession overview

Pharmacogenomics is the application of genomic technologies to drug discovery and further characterization of drugs related to an organism's entire genome. This is how scientists refer to the liver as a detoxifying organ.

Medicines were compiled in books called pharmacopoeias. The benefit of lowering BP, particularly with diuretics has been proven in many outcome studies.

Branches of pharmacology ppt

In the United States , the main body that regulates pharmaceuticals is the Food and Drug Administration and they enforce standards set by the United States Pharmacopoeia. In the 17th century, the English Physician Nicholas Culpeper translated and used pharmacological texts. July Main articles: Ligand biochemistry , List of drugs , and Neurotransmitter The cholinergic synapse. The immense obstacle for the medicine molecules is almost impossible to penetrate and the drug enters a barricade known as the blood-brain barrier. Culpepper detailed plants and the conditions they could treat. Indapamide has a dual mechanism of action: diuretic effect at the level of the distal tubule in the kidney and a direct vascular effect, both of which contribute to the antihypertensive efficacy of the drug. These include neuropharmacology , in the central and peripheral nervous systems ; immunopharmacology in the immune system. In the European Union , the main body that regulates pharmaceuticals is the EMA and they enforce standards set by the European Pharmacopoeia.
