Anticholinergic Drugs

Anticholinergic Drugs selectively reduce or abolish the muscarinic receptor mediated effects of acetyicholine and parasympathetic stimulation. So Anticholinergic Drugs are also called antimuscarinic or parasympatholytic agents. Anticholinergic Drugs drugs inhibit the actions of endogenous acetylcholine and muscarinic agonists at muscarinic receptor sites in peripheral tissues and in the central nervous …

Cholinergic Agonists

Acetyicholine is a physiological neurotransmitter which acts on both muscarinic and nicotinic receptors. It is not useful as a drug being non-specific and having short duration of action. So such compounds have been developed which are more selective and have longer duration of action than acetylcholine. Drugs, which combine with …

Autonomous nervous system

Autonomous nervous system (ANS) is divided into sympathetic (adrenergic) and parasympathetic (cholinergic) divisions. Autonomous nervous system maintains homeostasis by integrating with sensory, somatomotor, endocrinal, metabolic, immunological and emotional activities. The limbic system and hypothalamus coordinate autonomic reactions with emotions. Anteromedial and posterolateral nuclei of hypothalamus are associated with cholinergic and …

Tricyclic antidepressant

Tricyclic Antidepressant effect of these drugs depends on their effect on biogenic amine neurotransmitters: 1. Imipramine, clomipramine, amitriptyline and doxepin are Tricyclic Antidepressant. They block the amines norepinephrine (NE) or serotonin reuptake pumps and permit a longer sojourn of neurotransmitter at the receptor site. They also bind to c— adrenergic, …

Anxiolytics

Anxiety may be due to minor mal adjustments in day to day life. Such individuals complain of ‘tension’ with vague symptoms without any obvious signs of illness. In fact they do not really need drug (Anxiolytics) therapy. In pathological anxiety, behavioural and mental functions are often severely impaired. So anxiety …

NSAID

The characteristic features of NSAID are: 1. NSAID are weak analgesics than narcotic analgesics. 2. Unlike narcotic (opioid) analgesics, NSAID do not induce central depressant and sedative activity, so they are called non- narcotic (non-opioid) analgesics. 3. Most of NSAID have additional anti- inflammatory and antipyretic effects. 4. NSAID do …

Cytokines play a central part in the human immune response and therefore rheumatoid arthritis. Out of wide range of cytokines TNF-ct (tissue necrosing factor-alfa) appears to be at the heart of the inflammatory process in the joints of rheumatoid arthritis patients. Anti TNF Drugs: TNF-ct is produced by macrophages and …
