Mepenzolate is a postganglionic parasympathetic inhibitor. It decreases gastric acid and pepsin secretion and suppresses spontaneous contractions of the colon. It specifically antagonizes muscarinic receptors. Mepenzolate is marketed under the brand name CANTIL. CANTIL is indicated for use as adjunctive therapy in the treatment of peptic ulcer. It has not been shown to be effective in contributing to the healing of peptic ulcer, decreasing the rate of recurrence, or preventing complications.

Oleandomycin is a macrolide antibiotic, which was first described under the designation P.A.105 by Sobin, English, and Celmer (1954-5). Later it appeared on the market under three names and in two forms: as pure oleandomycin ("matromycin," Pfizer; "romicil," Hoffmann-La Roche) and as a mixture with twice its weight of tetracycline ("sigmamycin," Pfizer). Oleandomycin can be employed to inhibit the activities of bacteria responsible for causing infections in the upper respiratory tract much like Erythromycin can. Both can affect staphylococcus and enterococcus genera. Oleoandomycin is reported to inhibit most gram-positive bacteria, but has only a slight inhibiting effect on gram-negative bacteria, rickettsiae, and larger viruses. The spectrum of activity on micro-organisms is therefore wider than that of penicillin and streptomycin, but narrower than that of chloramphenicol and the tetracyclines. Oleandomycin is approved as a veterinary antibiotic in some countries. It has been approved as a swine and poultry antibiotic in the United States. However, it is currently only approved in the United States for production uses. Oleandomycin is a bacteriostatic agent. Like erythromycin, oleandomycin binds to the 50s subunit of bacterial ribosomes, inhibiting the completion of proteins vital to survival and replication. It interferes with translational activity but also with 50s subunit formation. However, unlike erythromycin and its effective synthetic derivatives, it lacks a 12-hydroxyl group and a 3-methoxy group. This change in structure may adversely affect its interactions with 50S structures and explain why it is a less powerful antibiotic.

Docusate, also known as docusate salts or dioctyl sulfosuccinate, prevents/relieves dry hard stool and thus is used to treat constipation. Results usually occurs 1 to 3 days after the first dose. In North America, docusate and a stimulant laxative such as sennosides are commonly used in bowel treatment protocols associated with institutionalized elderly and oncology treatments. A paucity of evidence is available to support the use of the stool softener docusate yet it continues to be prescribed in everyday clinical practice for the aforementioned populations. While the actual cost of docusate is low, additional costs associated with its administration (i.e. nursing time) and its widespread use can be significant. Docusate is absorbed into the bloodstream and excreted via the gallbladder after undergoing extensive metabolism. The effect of docusate may not necessarily be all due to its surfactant properties. Perfusion studies suggest that docusate inhibits fluid absorption or stimulates secretion in the portion of the small intestine known as the jejunum

Ambenonium is a cholinesterase inhibitor with all the pharmacologic actions of acetylcholine, both the muscarinic and nicotinic types. It was marketed under the brand name Mytelase, but was withdrawn from the market in the United States in 2010. Ambenonium, similar to pyridostigmine and neostigmine, is used for the treatment of muscle weakness and fatigue in people with myasthenia gravis.Ambenonium exerts its actions against myasthenia gravis by competitive, reversible inhibition of acetylcholinesterase. The disease myasthenia gravis occurs when the body inappropriately produces antibodies against acetylcholine receptors, and thus inhibits proper acetylcholine signal transmission (when acetylcholine binds to acetylcholine receptors of striated muscle fibers, it stimulates those fibers to contract). Ambenonium reversibly binds acetylcholinesterase at the anionic site, which results in the blockage of the site of acetycholine binding, thereby inhibiting acetylcholine hydrolysis and enhancing cholinergic function through the accumulation of acetycholine at cholinergic synpases. In turn this facilitates transmission of impulses across the myoneural junction and effectively treats the disease.
