Receptors * Serve as recognition sites for specific endogenous compounds such as: 1. Neurotransmitters‚ e.g. noradrenaline 2. Hormones (thyroid hormones) 3. Local Hormones /Autacoids (released and act upon the same/nearby tissue‚ e.g. prostaglandins) Drug Receptors Most drugs exert their effects‚ by interacting with receptors present on the cell surface or intracellularly Action occurs when drug binds to receptor and this action may be: Ion channel is opened or closed Second messenger

Prevention Aim‚ Method‚ Results‚ Outcome – evaluate findings of the study WRITTEN REPORT Thromboxanes are a group of eicosanoids derived from Arachidonic Acid. They are synthesised through the cyclooxygenase pathway‚ and are derivatives of the prostaglandin intermediate‚ PGH2. In platelets‚ thromboxane synthase is the enzyme responsible for the conversion of Thromboxane into its active form‚ Thromboxane A2 (TXA2). In the event of vascular injury‚ platelets release Adenosine diphosphate (ADP) and TXA2
