Chlorcyclizine is a first generation phenylpiperazine class antihistamine used to treat urticaria, rhinitis, pruritus, and other allergy symptoms. Chlorcyclizine also has some local anesthetic, anticholinergic, and antiserotonergic properties, and can be used as an antiemetic. Chlorcyclizine temporarily relieves the symptoms due to hay fever or other upper respiratory allergies. It has also being shown to possess in vitro and in vivo activity against hepatitis C virus.

Chlorpheniramine is an antihistamine. Chlorpheniramine binds to the histamine H1 receptor. This blocks the action of endogenous histamine, which subsequently leads to temporary relief of the negative symptoms brought on by histamine. Chlorpheniramine is used for relieving symptoms of sinus congestion, sinus pressure, runny nose, watery eyes, itching of the nose and throat, and sneezing due to upper respiratory infections (eg, colds), allergies, and hay fever. In addition to being a histamine H1 receptor (HRH1) antagonist, chlorphenamine has been shown to work as a serotonin-norepinephrine reuptake inhibitor or SNRI.

Propylhexedrine is considered to be an agonist of alpha-adrenergic receptors. It is effective as a topical vasoconstrictor. The primary medicinal use of Benzedrex (Propylhexedrine inhaler) propylhexedrine is temporary symptomatic relief of nasal decongestion due to colds, allergies and allergic rhinitis. Structurally and pharmacologically related to amphetamine.Exact mechanism of action unknown but thought to be similar to amphetamine. When used as a nasal inhaler for this indication, propylhexedrine reduces nasal airway resistance without producing rebound congestion. Abuse does not occur by nasal inhalation; however, a small amount of abuse of the propylhexedrine containing nasal inhalers occurs by oral ingestion of the contents of the inhaler or by intravenous injection. Propylhexedrine is a central nervous system (CNS) stimulant of low abuse potential, a stimulant of low preference for stimulant abusers compared with amphetamine, methylphenidate, phenmetrazine.

Methoxamine is an alpha-adrenergic agonist that induces prolonged peripheral vasoconstriction, and can also stimulate the release of arginine vasopressin in humans. In clinical trials, methoxamine was found to improve fecal incontinence. It had been marketed by Glaxo-Smith-Kline under the brand name Vasoxyl but has been discontinued. Methoxamine was also found to stimulate the induction of hiPSC-derived hepatoblasts to ALBUMIN+ cells.

Adenosine monophosphate (AMP) is a nucleotide, consisting of a phosphate group, the sugar ribose, and the nucleobase adenine. AMP is an activator of several enzymes in the tissues. In the glycolytic pathway, the enzyme phosphofructokinase is inhibited by ATP but the inhibition is reversed by AMP, the deciding factor for the reaction being the ratio between ATP and AMP. In medicine, AMP is used mainly as an alternative to adenosine for treatment of ischemia and as a tool compound to measure hyperresponsiveness of airways.

Nicotinyl alcohol is a direct-acting vasolidator, that may decrease the blood pressure and it is a cholesterol-lowering agent. Nicotinyl alcohol as a tartrate salt led to the efficiency improvements in patients with intermittent claudication. In addition, nicotinyl alcohol alone or associated with other drugs was studied in the treatment of radicular syndromes; and was shown, that the effect had not been due to mechanical compression.
