← Drugs Affecting ANS
← Cholinergic Drugs
1. Cholinergic Agonist:
← Direct Acting:
Cholinergic agonists (also known as parasympathomimetics) mimic the effects of acetylcholine by binding directly to cholinoceptors.
Acetylcholine, Pilocarpine, Bethanecol, Carbachol.
← Indirect Acting:
Acetylcholinesterase is an enzyme that specifically cleaves acetylcholine to acetate and choline and, thus, terminates its actions. Inhibitors of acetylcholinesterase indirectly provide a cholinergic action by prolonging the lifetime of acetylcholine.
Physostigmine, Neostigmine, Ecothiophate, Rivastigmine, Tacrine.
← Reactivation of Actylcholine-esterase:
Pralidoxime.
2. Cholinergic Antagonist:
← Antimuscarinic:
Commonly known as antimuscarinics, these agents block muscarinic receptors, causing inhibition of all muscarinic functions.
Atropine, Scopolamine, Ipratropium.
← Ganglionic Bolckers:
Ganglionic blockers specifically act on the nicotinic receptors of both parasympathetic and sympathetic autonomic ganglia. Except for nicotine, the other drugs mentioned in this category are nondepolarizing, competitive antagonists.
Mecylamine, Nicotine.
← Neuromuscular Bolckers:
These neuromuscular blockers are structural analogs of acetylcholine, and they act either as antagonists (nondepolarizing type) or agonists (depolarizing type) at the receptors on the end plate of the neuromuscular junction. Neuromuscular blockers are clinically useful during surgery for producing complete muscle relaxation
Atracurium, Doxacurium, Succinylcholine, Tubocurarine.
← Adrenergic Drugs
1. Agrenergic Agonist:
← Direct Acting:
These drugs act directly on α or β receptors, producing effects similar to those that occur following stimulation of sympathetic nerves or release of the hormone epinephrine from the adrenal medulla.
Dopamine, Epinephrine, Norepinephrine, Phenylephrine, Sameterol, Terbutaline.
← Indirect Acting:
These agents, which include amphetamine, cocaine and tyramine, may block the uptake of norepinephrine (uptake blockers) or are taken up into the presynaptic neuron and cause the release of norepinephrine from the cytoplasmic pools or vesicles of the adrenergic neuron. As with neuronal stimulation, the norepinephrine then traverses the synapse and binds to the α or β receptors.
Amphetamine, Cocaine, Tyramine.
← Mixed:
Capacity both to stimulate adrenoceptors directly and to release norepinephrine from the adrenergic neuron.
Ephedrine, Pseudoephedrine.
2. Adrenergic Antagonist:
← α-Blockers:
Drugs that block α-adrenoceptors profoundly affect blood pressure.
Doxazocin, Prazocin, Terazocin, Tamsulosin.

Atenolol, Esmolol, Labetalol, Pindolol.
← NT Uptake or Release:
Guanethidine, Reserpine.
← CNS Drugs
← Anti-Parkinsonism Drugs:

Phenelzine, Selegiline.
f. Anti-Mania & Bipolar Disorders:

← Pharmaceutical Alternatives: If two drugs contain same drug molecule but in different chemical form e.g different salt or strength.
← Bioavailability: Rate and extent to which a drug is absorbed from the site of administration and become available at the site of action.
← Bioeuivalence: Drugs showing same bioavailability are said to be bioequivalent.
← Essentially Similar Product: A copy of the research or Innovator Product. (ME 2)
← Biopharm Concepts
← Therapeutic Equivalents: If two drugs provide the same desired therapeutic effect with same safety and efficacy.
← Cmax: Maximum Drug Plasma concentration partly depends on the rate of release of drug from the formulation.
