C7 bulbs are smaller than C9 bulbs by 1 inch. C7 bulbs are 2 inches long and C9 bulbs are 3 inches long. C7 bulbs sit in a base known as a candelabra base and can only fit in this specific type of base. C9 bulbs sit in a base known as an intermediate base.
A drug that is an agonist attaches itself to receptors in the brain, and then produces a chemical reaction. For example, heroin is an opioid agonist. It binds to opioid receptors that control pleasure and pain, the result being a feeling of euphoria and well being.Other examples of opioid agonists, sometimes referred to as âfull agonists,â are oxycodone, morphine and opium.ntagonist therapy has several benefits. Patients receiving antagonist drugs, such as Naltrexone, which is used in the treatment of opioid addiction, do not develop a tolerance to the medication. Additionally, antagonist drugs are not addictive in and of themselves.
An inverse agonist is an agent that binds to the same receptor binding-site as an agonist for that receptor and inhibits the constitutive activity of the receptor. Inverse agonists exert the opposite pharmacological effect of a receptor agonist, not merely an absence of the agonist effect as seen with antagonist.An example is the cannabinoid inverse agonist rimonabant. A co-agonist works with other co-agonists to produce the desired effect together.ull agonists bind (have affinity for) and activate a receptor, producing full efficacy at that receptor. One example of a drug that acts as a full agonist is isoproterenol, which mimics the action of adrenaline at Î² adrenoreceptors.
