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.

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.
Acetylcholine binds to two of the five AChR subunits which causes the channel to change shape and open, the chanel is then lined with negatively charges amino acids, allowing the sodium ions to flow into the cell; the sodium ion buildup then leads to muscle contraction.
