Classification of Antiadrenergic Drugs | Pharmacology | Animals

After reading this article we will learn about the classification of antiadrenergic drugs These are the drugs which antagonize the pharmacological action of sympathomimetic agents or alter the function of sympathetic nervous system inside the body. Classification: On the basis of mechanism of action. 1. α-Adrenoceptor Antagonists: Phenoxy-benzamine: (i) Phenoxy-benzamine is a halo-alkyl-amine. It binds covalently to the α receptors [...]

Sympathetic and Parasympathetic Nerve Fibres | Pharmacology

This article will help you to differentiate between sympathetic and parasympathetic nerve fibres. Difference # Sympathetic Nerve Fibre: 1. They arise from thoraco-lumber (T1 to L3) region of the spinal cord. 2. Ganglia are nearer to CNS. The ratio of pre and postganglionic fibres is generally 1: 20 or more. So, the post ganglionic fibers are longer. 3. Neurotransmitters are [...]

Classification of Cholinergic Drugs |Animals| Pharmacology

After reading this article we will learn about the classification of cholinergic drugs. These are the drugs which produce Ach-like actions, either directly by interact­ing with the cholinergic receptors or indirectly by increasing availability of Ach at these sites. Classification: On the basis of mechanism of action. Organ Selectivity: (i) Ach → all cholinergic organs, more preferably on GIT. (ii) [...]
