Carbapenems can only be given through an intravenous drip, which usually does not cause irritation at the injection site. If you have a severe allergy to penicillin, you generally should not be given a carbapenem. However, many patients with a mild or moderate allergy can tolerate carbapenems.
Alpha-1 adrenergic agonists. Alpha-1 adrenergic agonists stimulate alpha-1 receptors coupled to G proteins and phospholipase C. They can be classified in two groups: those which do not cross the blood-brain barrier and have peripheral effects and those which penetrate into the brain and have mainly central effects. Alpha-1 agonists with peripheral effects.
The inverse agonist binds on the same receptor as the agonist but gives the opposite effect from the agonist. An antagonist, however, can merely block the activity of both an agonist and its inverse agonist but can't create a response if given on it's own (without an agonist or inverse agonist to compete with).tasad4y Â· 1 year ago.
