🔴DEFINITION

🔶Anticholinergic:

Opposing the actions of the neurotransmitter acetylcholine. Anticholinergic drugs inhibit the transmission of parasympathetic nerve impulses, thereby reducing spasms of smooth muscles .

🔶Antimuscarinic drugs :

Inhibiting or preventing the actions of muscarine and muscarinelike agents, or the effects of parasympathetic stimulation at the neuroeffector junction.

🔶antinicotinic drugs=

That inhibits the actions of nicotine and nicotine-like agents on the nicotinic acetylcholine receptors.

🔶 Anti-neoplastic agents :

The agents/drugs which are used in the treatment of cancer is called as anti-neoplastic agents.

🔶 Absorption :

The movement of drugs from its site of administration into the circulation is called as absorption.
🔴MECHANISM OF ACTION

📌ATROPINE

Atropine is an antimuscarinic that works through competitive inhibition of postganglionic acetylcholine receptors and direct vagolytic action, which leads to parasympathetic inhibition of the acetylcholine receptors in smooth muscle.
The end effect of increased parasympathetic inhibition allows for preexisting sympathetic stimulation to predominate, creating increased cardiac output and other associated antimuscarinic side effects

📌CYCLOPENTOLATE
It is a muscarinic antagonist. 
It is commonly used as an eye drop during pediatric eye examinations to dilate the eye (mydriatic) and prevent the eye from focusing/accommodating (cycloplegic). Cyclopentolate or atropine can also be administered to reverse muscarinic and central nervous system effects of indirect cholinomimetic  administration.
🔴Mechanism of Protein-Drug Binding
  
         Binding of drugs to proteins is generally reversible which suggests that it generally involves weak chemical bonds such as :
1. Hydrogen bonds
2. Hydrophobic bonds
3. Ionic bonds
4. van der Waal's forces
■ Binding of drugs falls into 2 classes :
Binding of drugs to blood components like --
(a) Plasma Proteins
(b) Blood cells
Binding of drugs to extracellular tissue proteins,fats, bones, etc.

📌Binding of drugs to Blood Components
🔹Plasma Proteins-DrugBinding:-
 The interaction of drug in the blood compartment is with the plasma proteins which are present in abundant amounts ∈ large variety.
The order of binding of drugs to plasma proteins is :
Albumin > alpha1-Acid Glycoprotein > Lipoproteins > Globulins.
🔹Binding of drugs to Human Serum Albumin :-
The human serum albumin(HSA),having a molecular weight 65,000 is most abundant plasma protein. The HSA can bind several compounds.
4 different sites on HSA for drug binding:-
-Site I :- Warfarin &Azapropazone binding site
-Site II:- Diazepam binding site
-Site III:- Digitoxin binding site
-Site IV:- Tamoxifen binding site
🔹Binding of drugs to alpha1-Acid Glycoprotein :-
It is also known as Orosomucoid it has a molecular weight of 44,000 & a plasma concentration range of 0.04 - 0.1%.
It binds to the number of drugs like Imipramine,Lidocaine, Propranolol &Quinidine,etc.
🔹Binding of drugs to Lipoproteins :-
The drug that binds to lipoproteins does so by dissolving in the lipid core of the protein & its capacity to bind depends upon its lipid  content.
They are classified in the basis of their density into 4 categories:-
1. Chylomicrons(least dense & largest in size).
2. Very low density lipoproteins(VLDL)
3. Low density lipoproteins(LDL)predominant in humans.
4. High density lipoproteins(HDL)most dense& smallest in size.
🔹Binding of drugs to Globulins :-
Different types of plasma globulins are binds they are:-
1. alpha1-globulin:-also called as Transcortin or Corticosteroid Binding Globulin(CBG).It binds to thyroxine & cyanocobalamin.
2. alpha2-globulin:-also called as Ceruloplasmin. It binds to vit.A,D,E,K & cupric ions.
3. beta1-globulin:-also called as Transferrin. It binds to ferrous ions.
4. beta2-globulin:-It binds to carotenoids.
5. gamma-globulin:-It binds specifically you antigens.
🔹Binding of drugs to Blood cells:-
More than 40%of the blood comprises of blood cells of which the major cell component is the RBC.
The RBC comprises of 3 components each of which bind to drugs :-
1. Haemoglobin: Drugs like Phenytoin,  phenobarbital & phenothaizines bind to Hb.
2. Carbonic Anhydrous: Drugs bind to acetazolamide & chlorthalidone.
3. Cell Membrane: Imipramine & chlorpromazine are bind with the RBC membrane.

📌Tissue binding of drugs
--A drug can bind to one or more of the several tissue components.
--Tissue drug binding is important in distribution from 2 points :
1. It increases the apparent volume of distribution of drugs in contrast to plasma protein binding which decreases it.
2. Tigssue drug binding results in localization of a drug at a specific site in the body.
--Drugs that bind to extracellular tissues the order of binding is:
Liver > Kidney > Lung > Muscles
