NEET MDS Lessons
Pharmacology
Pramlintide -Amylin mimetics
Mechanism
synthetic analogue of human amylin that acts in conjunction with insulin
↓ release of glucagon
delays gastric emptying
Clinical use
type I and II DM
PLASMA FRACTIONS:
a) Fresh frozen plasma.
b) Platelets.
c) Plasma concentrates.
d) Non-plasma recombinant factor concentrates.
VITAMIN -K
- Group of lipophilic, hydrophobic vitamins.
- Needed for the post-translational modification of coagulation proteins.
- Phylloquinone (vitamin K1) is the major dietary form of vitamin K.
- Vitamin K2 (menaquinone, menatetrenone) is produced by bacteria in the intestines.
Piroxicam:
Half‐life of 45 hrs. Once‐daily dosing. Delay onset of action.
High doses inhibits PMN migration, decrease oxygen radical production, inhibits lymphocyte function.
used to relieve the symptoms of arthritis, primary dysmenorrhoea, pyrexia; and as an analgesic,non-selective cyclooxygenase (COX) inhibitor
The risk of adverse side efects is nearly ten times higher than with other NSAIDs. Peptic ulcer (9.5 higher)

Oxytetracycline
Treats Oxytetracycline is a medicine used for treating a wide range of infections including infections of the lungs, urinary system, skin and eyes. It may also be used to treat sexually transmitted infections, infections caused by lice, rickettsial infections, cholera and plague. It is very occasionally used to treat leptospirosis, gas gangrene, and tetanus.
Heroin (diacetyl morphine)
Heroin is synthetically derived from the natural opioid alkaloid morphine
Largely owing to its very rapid onset of action and very short half-life, heroin is a popular drug of abuse
It is most effective when used intravenously
Heroin is rapidly deacetylated to 6-monoacetyl morphine and morphine, both of which are active at the mu opioid receptor
More lipid soluble than morphine and about 2½ times more potent. It enters the CNS more readily.
