Phenpromethamine is an adrenergic agent. Phenpromethamine was used as vasodilator agent. It is a stimulant which is banned in sport. It is available in supplements which are sold as fat burners or pre-workout boosters. Phenpromethamine is a potent CYP2D6 inhibitor.
Pantothenic acid (known as Vitamin B5) is a water-soluble member of the B-vitamin family that is converted into 4’-phosphopantetheine, which is then converted to co-enzyme A (CoA) via adenosine triphosphate. Pantothenic acid regulates epidermal barrier function and keratinocytes differentiation via CoA metabolism. Pantothenic acid is incorporated into co-enzyme A and protects cells against peroxidative damage by increasing the level of glutathione. A recent feasibility study has also shown that daily oral supplementation of a nutritional agent containing pantothenic acid for 8 weeks was feasible and safe. It was discovered the different pharmacological implementation of pantothenic acid, such as treatment of acne, obesity. Existed some reports, mentioned efficacy using pantothenic acid in systemic lupus erythematosus. Significant reduction in morning stiffness, degree of disability, and severity of pain was reported for persons taking pantothenic acid in case of osteoarthritis and rheumatoid arthritis. Vitamin B5 may increase the effects of a group of drugs called cholinesterase inhibitors, which are used to treat Alzheimer's disease. That might lead to severe side effects.

Dehydrocholic acid is manufactured from cholic acid by oxidation. The main use of dehydrocholic acid is as a digestive aid in the dietary supplement industry. It is typically formulated with enzymes like papain and pancreatin. It has a stimulating effect on the secretion of bile by the liver (choleretic); improves absorption of essential food materials in states associated with deficient bile formation.

MERSALYL (Mersal) is an organomercury compound, mercurial diuretics that superseded by safer diuretics such as thiazides, and is hardly used anymore. Due to the idiosyncratic nature of mercury toxicity, the risk of severe disease and sudden death are unpredictable and frequently show no warning signs. Mercurial diuretics cause diuresis by reducing the reabsorption sodium in the ascending loop of Henle, thus causing more water being delivered to the distal convoluted tubule. Unfortunately, earlier physicians misconstrued hallmark symptoms of mercury poisoning such as excessive salivation as signs of mercury's efficacy, including up until the early 1960s when the use of mercurial diuretics was halted in medicine.

Hydroxyamphetamine is a derivative of amphetamines. Hydroxyamphetamine is intended mainly as local eye drops for diagnostic purposes. It is indirect sympathomimetic agent which cause dilation of the eye pupil before diagnostic test. Among the minor side effects from its use are: change in color vision, difficulty seeing at night, dry mouth, headache, increased sensitivity of eyes to sunlight, muscle stiffness or tightness and temporary stinging in the eyes. The main use of hydroxyamphetamines as eye drops is the diagnosis of Horner's syndrome which is characterized by nerve lesions. Hydroxyamphetamine hydrobromide is a component of FDA approved brand drug - Paremyd sterile ophthalmic solution (Hydroxyamphetamine hydrobromide, USP 1.0%, Tropicamide, USP 0.25%). Hydroxyamphetamine is an indirect-acting sympathomimetic, while tropicamide acts as a parasympatholytic.

Oxedrine (Sympatol, p-synephrine) is a naturally occurring alkaloid molecule first appeared in Europe towards the end of the 1920s being sold as a drug under the brand name Sympatol. Oxedrine was then being prescribed as a remedy for a number of respiratory conditions, which include asthma, whooping cough, colds, and hay fever. More recently, synephrine gained popularity as a weight loss aid and it has become a favored component in the more popular brands of weight loss supplement stacks. This popularity can be attributed in part to the ban imposed on ephedra, to which it shares similar mechanisms of action. Most, if not all of the synephrine being sold as a dietary supplement is extracted and synthesized from the Citrus aurantium plant, more commonly known as bitter orange. Just like ephedrine, synephrine has vasoconstrictive abilities, although at a lesser potency compared to ephedrine. There is no mention of synephrine in editions of Drill's Pharmacology in Medicine later than the 3rd, nor is there any reference to synephrine in the 2012 Physicians' Desk Reference, nor in the current FDA "Orange Book". One current reference source describes synephrine as a vasoconstrictor that has been given to hypotensive patients, orally or by injection, in doses of 20–100 mg.

The discovery of pamaquine, developed by replacing one of the methyl groups of methylene blue by a dialkylaminoalkyl chain, was a landmark in the design of drugs for malaria. It is closely related to primaquine. The administration of pamaquine during the incubation period delayed but did not prevent primary attacks of a New Guinea strain of Plasmodium vivax malaria. Hemolytic anemia after administration of the antimalarial drug pamaquine was reported in patients with Glucose-6-phosphate dehydrogenase (G6PD) deficiency. Pamaquine itself could not be used clinically due to high toxicity.
Potassium Glycyrrhetinate (CAS no. 85985-61-1) is the potassium salt of Glycyrrhetinic Acid. Potassium Glycyrrhetinate is also known as Olean-12-En-29-Oic Acid, 3-Hydroxy-1, 1-Oxo-, Monopotassium Salt. Potassium Glycyrrhetinate functions as a flavoring agent and skin-conditioning agent—miscellaneous in cosmetic products.
