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.
From Wikipedia, the free encyclopedia. Gamma-aminobutyric acid. A GABA receptor agonist is a drug that is an agonist for one or more of the GABA receptors, producing typically sedative effects, and may also cause other effects such as anxiolytic, anticonvulsant, and muscle relaxant effects.There are three receptors of the gamma-aminobutyric acid.any commonly used sedative and anxiolytic drugs that affect the GABA receptor complex aren't agonists. These drugs are known as positive allosteric modulators, and while they do bind to the GABA receptors, they cannot induce a response from the neuron without an actual agonist being present.
