Pholcodine is an opioid that has been widely used worldwide since 1950 for the treatment of non-productive cough in children and adults. Illicit drug. Additionally Pholcodine is a marker for sensitization to neuromuscular blocking agents (NMBA) and is intended for use as a diagnostic tool in NMBA-induced anaphylaxis.

Promethazine hydroxyethyl quaternary derivative of promethazine with antihistamine and anticholinergic properties. The drug lacked the sedative properties of promethazine. It was used in the clinic under tradename Aprobit.

Aescin, the major active principle from Aesculus hippocastanum (Hippocastanaceae) the horse chestnut tree, has shown satisfactory evidence for a clinically significant activity in chronic venous insufficiency (CVI), haemorrhoids and post-operative oedema. In one controlled trial aescin was shown to be as effective as compression therapy as an alternative to medical treatment for CVI. The therapeutic benefit is well supported by a number of experimental investigations in different animal models, indicative of clearcut anti-oedematous, anti-inflammatory and venotonic properties, mainly related to the molecular mechanism of the agent, allowing improved entry of ions into channels, thus raising venous tension in both in vitro and in vivo conditions. Other mechanisms, i.e. release of PGF2 from veins, antagonism to 5-HT and histamine, reduced catabolism of tissue mucopolysaccharides, further underline the wide ranging mechanisms of the therapeutic activity of aescin. Aescin exists in two forms, α and β. β-aescin (b-escin) appears to be the active component of the mixture and is the molecular form present in major available pharmaceutical products. Beta-aescin has cytotoxic activity toward human colon adenocarcinoma cell lines.

Gepefrine (Pressionorm and Wintonin) is an antihypotensive agent. It was used for therapy of orthostatic dysregulation. One hour after oral administration of 30 mg or 45 mg gepefrine the blood pressure increased significantly at rest and more markedly on standing and during the step test. Gepefrine led to a reduction in pathological orthostatic regulation during the early phase as well as to the prevention of subjective and objective signs of orthostatic adjustment disorder during the late phase. Patients with insufficient rise in blood pressure during the step test (80 watts) showed after gepefrine a distinct tendency towards normalisation and the regression of subjective states of exhaustion. Gepefrine caused on average no substantive alternations in heart rate during all phases of the investigation. Complications or side-effects due to the method or the medicament were not observed.

Fenethylline (generic name Captagon) is a codrug of amphetamine and theophylline. In the fenetylline molecule, theophylline is covalently linked with amphetamine via an alkyl chain. It was formerly used to treat conditions such as ADHD, narcolepsy, and depression, but its use has been banned because of the potential for abuse. Amphetamine, an agonist for trace amine-associated receptor 1 (TAAR1) with enhancing dopamine signaling (an increase of irritability, aggression, etc.), is the main cause of Captagon addiction. Theophylline, an antagonist that blocks adenosine receptors (e.g. A2aR) in the brain responsible for restlessness and painlessness, may attenuate the behavioral sensitization caused by amphetamine. Fenethylline is included in a list of compounds to be considered by a World Health Organization (WHO) Expert Committee in April 1985 for possible international scheduling under the Convention on Psychotropic Substances, 1971. Fenethylline re-emerged because of its widespread abuse by Middle Eastern young adults. Terrorist groups such as the Islamic State to enhance what they consider desirable characteristics - aggressiveness, alertness, and fearlessness - in their recruits, promote it.

Medrylamine is an antihistamine agent. It was used topically. Medrylamine offers sure relief from allergic manifestations of varied and unknown etiologies

Mefenorex or (+/-)N-(3-chloropropyl)-1-methyl-2-phenylethylamine is an N-alkylated analogue of amphetamine. The therapeutic efficacy of mefenorex as an adjunctive support in the treatment of obesity for limited periods of time, as well as its ability to be well tolerated, has been amply demonstrated. Mefenorex is considered to be racemic mixture, no available data regarding enantiospecific pharmacological activity of the compound.
