Approach Considerations. Once a working diagnosis of acute pancreatitis is reached, laboratory tests are obtained to support the clinical impression. In addition to confirming the diagnosis, laboratory tests are helpful in determining the etiology and looking for complications. Although diagnostic imaging is unnecessary in most cases of pancreatitis, visualization of inflammatory changes within the pancreas provides morphologic confirmation of the diagnosis.
Carbastat - Clinical Pharmacology. Carbachol is a potent cholinergic (parasympathomimetic) agent which produces constriction of the iris and ciliary body resulting in reduction in intraocular pressure. The exact mechanism by which carbachol lowers intraocular pressure is not precisely known.
The mechanism of action of a medication is the specific biological process through which the medication causes the reduction in symptoms. For example, the mechanism of action of selective serotonin reuptake inhibitors, or SSRIs, is well known.
