Hyperlipemia
Excess tag
Hyperlipidemia
Hyperlipoproteinemia
Cholesterol
Hydrophilic
Cholesteryl ester
Hydrophilic
Chylomicrons carrying dietary TAGs to the liver
Can’t be decreased or increased with any intervention
Hyper TAG

Hypopituitarism
Corticos
Hypolipidemic drugs
Statins
Niacin
Fabric Acid Derivatives (Fibrates)
Bike acid - binding resins
Inhibitors of Intestinal Sterol Absorption
Statins - HMG-CoA reductase inhibitors
(3 - hydroxy, 3-methyl glutaryl CoA recuctase)
Lovostatin
Simvastatin
Pravastatin
Atrovastatin
Fluvaastatin
Ruaovastatin
Pitavastatin
Statins
Decreases chol.
And LDL receptors
Decreasing LDL in plasma
Increasing HDL
Decreases TAG
Pleutropic effect of statins
Improved endothelial function
Reduced inflammation reduced platelet aggregation
Neivascularisation jnductuon in ischaemic tissues
Antithrombotic
Enhanced fibrinolysis and immune suppression
Statins taken orally excreted jn bile, urine and feces
Taken at bed time because long half life (1-3hrs except:
Atrova (14hrs), rosuva (12hrs) and pitava statin (19hrs)
Statins used in
All types of hyperlipidemia
-alone or with others like resins, niacin or ezetimibe
Use immediately after ACE
Adverse effects
High ALT and AST (×3)
Myopathy and rhabdomolysis
Break down of muscles
In blood stream
Pain
Dark cola red
Potentiate oral anticoagulants and antidiabetic ad they displace them from plasma proteins
Statins
Not used in pregnancy and lactation
No chol. for hormones and milk
Niacin - nicotinic acid
Decreases bothe VLDL and LDL and increases HDL so they can be combined with statins for synergism
Mechanism of Niacin (absorbed orally)
Adipose tissue
Liver
Plasma
In adipose
Niacin binds to it’s receptors decreasing mobilisation of FA so no TAG and no VLDL
In the liver (no synthesis and esteeification of fat)
Inhibits DAG acetyl transferase so no TAG synthesis and no VLDL
In plasma
Increases LipoProtein Lipase activity that clears VLDL and chylomicron
Niacin used for
Mixed hyperlipidemia
Taken with oher drugs
