Drugs can bind to and stimulate cholinergic receptors directly.They can also inhibit the enzyme acetyl cholinesterase and slow ACh breakdown which causes an increase in synaptic levels and increased receptor stimulation.These drugs are called anticholinesterases.Direct-acting drugs can be classified as muscarinic or nicotinic drugs and have a specific action either on muscarinic or nicotinic receptors while anticholinesterases are non-specific and will act on both types.
