An Adrenergic antagonist is a pharmaceutical substance that acts to inhibit the action of the adrenergic receptors. It is thus a type of sympatholytic. It has the opposite effect as adrenergic agonists. More specifically, they can be divided into: [edit] External links | Adrenergics | | Receptor Ligands | | | Reuptake Inhibitors | | | Releasing Agents | Morpholines: Oxaflozane · Phendimetrazine · Phenmetrazine Oxazolines: 4-Methylaminorex (4-MAR, 4-MAX) · Aminorex · Clominorex · Cyclazodone · Fenozolone · Fluminorex · Pemoline · Thozalinone Phenethylamines (also Amphetamines, Cathinones, Phentermines, etc): 2-Hydroxyphenethylamine (2-OH-PEA) · 4-Methylamphetamine (4-MA) · 4-Methylmethamphetamine (4-MMA) · Alfetamine · Amfecloral · Amfepentorex · Amphetamine (Dextroamphetamine, Levoamphetamine) · Amphetaminil · β-Methylphenethylamine (β-Me-PEA) · Benzodioxolylbutanamine (BDB) · Benzodioxolylhydroxybutanamine (BOH) · Benzphetamine · Buphedrone · Butylone · Cathine · Cathinone · Clobenzorex · Clortermine · Diethylcathinone (Diethylpropion, Amfepramone) · Dimethoxyamphetamine (DMA) · Dimethoxymethamphetamine (DMMA) · Dimethylamphetamine · Dimethylcathinone (Dimethylpropion, Metamfepramone) · Ephedrine (EPH) · Ethcathinone (Ethylpropion) · Ethylamphetamine · Ethylbenzodioxolylbutanamine (EBDB) · Ethylone · Fenethylline · Fenproporex · Flephedrone · Fludorex · Furfenorex · Hordenine · Indanorex · Lisdexamfetamine · Lophophine (Homomyristicylamine) · Mefenorex · Mephedrone · Mephentermine · Methamphetamine (Desoxyephedrine, Methedrine; Dextromethamphetamine, Levomethamphetamine) · Methcathinone (Methylpropion) · Methedrone · Methoxymethylenedioxyamphetamine (MMDA) · Methoxymethylenedioxymethamphetamine (MMDMA) · Methylbenzodioxolylbutanamine (MBDB) · Methylenedioxyamphetamine (MDA; Tenamfetamine) · Methylenedioxyethylamphetamine (MDEA) · Methylenedioxyhydroxyamphetamine (MDOH) · Methylenedioxymethamphetamine (MDMA) · Methylenedioxymethylphenethylamine (MDMPEA; Homarylamine) · Methylenedioxyphenethylamine (MDPEA; Homopiperonylamine) · Methylone · Ortetamine · Parabromoamphetamine (PBA) · Parachloroamphetamine (PCA) · Parafluoroamphetamine (PFA) · Parafluoromethamphetamine (PFMA) · Parahydroxyamphetamine (PHA) · Paraiodoamphetamine (PIA) · Paramethoxyamphetamine (PMA) · Paramethoxyethylamphetamine (PMEA) · Paramethoxymethamphetamine (PMMA) · Paredrine (Norpholedrine, Oxamphetamine) · Phenethylamine (PEA) · Pholedrine · Phenpentermine · Phenpromethamine · Phentermine · Phenylpropanolamine (PPA) · Prenylamine · Propylamphetamine · Pseudoephedrine (PSE) · Tiflorex (Flutiorex) · Tyramine (TRA) · Xylopropamine · Zylofuramine Piperazines: 2,5-Dimethoxy-4-bromobenzylpiperazine (2C-B-BZP) · Benzylpiperazine (BZP) · Methoxyphenylpiperazine (MeOPP; Paraperazine) · Methylbenzylpiperazine (MBZP) · Methylenedioxybenzylpiperazine (MDBZP; Piperonylpiperazine) · Parafluorophenylpiperazine (pFPP; Fluoperazine); Others: 2-Amino-1,2-dihydronaphthalene (2-ADN) · 2-Aminoindane (2-AI) · 2-Aminotetralin (2-AT) · 2-Benzylpiperidine (2-BP) · 4-Benzylpiperidine (4-BP) · Clofenciclan · Cyclopentamine · Cypenamine · Cyprodenate · Feprosidnine · Gilutensin · Heptaminol · Hexacyclonate · Indanylaminopropane (IAP) · Isometheptene · Methylhexanamine · Naphthylaminopropane (NAP) · Octodrine · Phthalimidopropiophenone · Propylhexedrine (PHX) · Tuaminoheptane (Tuamine) | | Enzyme Inhibitors | | | | Others | | | |
