Types of Receptors

  1. Ligand-Gated Ion Channel Receptors
    They are found in excitable tissues such as nerves, muscles or heart. There function is mainly to regulate the entry of ions or electrolyte in the cell. The only way to open up the channel is through binding of the drug into the receptor.

  2. G- Protein Receptors
    Function is to regulate the stimulation or suppression of normal processes in the body that when a drug is bound into the receptor such as increase of heart rate, inhibition of secretion of saliva and alike are produced.

  3. Intracellular Receptors
    Receptor for hormonal functional. Examples are Estrogen and Thyroxine

  4. Tyrosine Kinase Receptor
    Located in the plasma membrane. Main function is for cell growth.
