1 Pharmacology

Ambroxol is a :

1) Mucolytic agent
2) Bronchial secretion enhancer
3) Antitussive
4) None of the above

Option 1

Expectorants (Mucokinetics)

(a) Bronchial secretion enhancers : Sodium or Potassium citrate, Potassium iodide, Guaiphenesin (Glyceryl guaiacolate), balsum of Tolu, Vasaka, Ammonium chloride.

(b) Mucolytics: Bromhexine Ambroxol Acetyl cysteine Carbocisteine

Option 2

Option 3

Option 4

2 Pharmacology

A Class III antiarrhythmic agent that blocks K+ channels, prolongs action potential duration , and lengthens QT interval.
1) propranolol
2) acebutolol
3) sotalol
4) esmolol

Option 1

Option 2

Option 3

Sotalol is a Class III antiarrhythmic agent that blocks K+ channels, prolongs action potential duration (APD), and lengthens QT interval.

Noncardiac selective beta-adrenergic blocker.

The D-isomer has less than 1/50 beta-blocking activity of the L-isomer.

Sotalol possesses 30% of beta-blocking activity of propranolol

Option 4

3 Pharmacology

The main excitatory neuro transmitter in CNS is
   1)    Glycine
   2)    Acetyl choline
   3)    Aspartate
   4)    Glutamate

Option 1

Option 2

The chemical compound acetylcholine (ACh) is a neurotransmitter in both the peripheral nervous system (PNS)and central nervous system (CNS) in many organisms including humans. Acetylcholine is one of many neurotransmitters in the autonomic nervous system (ANS) and the only neurotransmiter used in the somatic nervous system.

Option 3

Option 4

Option 1

Option 2

Option 3

Option 4

carbamazepine is the primary agent used in ment of trigeminal neuralgia

5 Pharmacology

A medication that reduces the rate of aqueous humor formation in acute glaucoma

1) phenothiazines
2) amphotericin B
3) Isoniazid
4) carbonic anhydrase inhibitors

Option 1

Option 2

Option 3

Option 4

Carbonic anhydrase is found in erythrocytes, kidney, gut, ciliary body, choroid plexus, and glial cells.
Carbonic anhydrase inhibitors are used primarily as probes for studying renal transport mechanisms and in the treatment of glaucoma
When used to treat glaucoma, carbonic anhydrase inhibitors diminish the transport of HCO3 - and Na+ by the ciliary process, which limits intraocular pressure.
This reduces the formation of aqueous humor by up to 50%, thereby reducing the intraocular pressure. These agents can also limit CSF and endolymph formation.
