Metoclopramide

Hello awesomites ! Today I am gonna talk about a drug named as "Metoclopramide".
Basically it's a anti-emetic drug.First let us know what is emesis !.In simple words emesis means vomiting.Chemoreceptor trigger zone (CTZ) is  located in area postrema and the nucleus tractus solitarius (NTS) of medulla oblongata.They both act as a important relay areas for afferent impulses arising in g.i.t.,throat and other viscera.
Metoclopramide is a Pro kinetic drug
It acts on GIT causing increase in peristaltic movement with relaxation of  pylorus .

Mechanism of action includes :

a)D2 antagonism:It Decreases dopamine concentration  and obviously acetylcholine concentration increases  !.Which causes activation of ACh receptors leading to increase in LES tone and gastric pressure .

b)5-HT4 agonism:Activates 5-HT4 receptors on primary afferent neurons (PAN) of the ENS,via excitatory interneurons.

Gastric hurrying and LES tonic effects are mainly due to this action which is synergised by bethanechol and attenuated by atropine .

c)5-HT3 antagonism: At high concentrations  it can block 5-HT3 receptors present on inhibitory myenteric interneurons and in NTS/CTZ .Increase in ACh concentration is also seen in minor condition


Long term use can cause parkinsonism-since decrease in dopamine , galactorrhea and gynecomastia .

It hastens use of many drugs like aspirin and diazepam by its action

2016: the flashback

Hey all!

In this post, I just want to share a flashback to the year 2016 and what I have learnt through the journey of these 365 days.

2016, you will be missed

Remember I promised 2016 was going to be awesome?

It was, it was. It was a beautiful year, personally.

Here's my year in review:

Create the change

Hello everyone

So it's the last day of 2016. And everyone is now talking about new year resolutions and stuff. But what do we want to resolve as medical students?

Remember the first day you joined the medical college? That day you promised yourself something. To be a good doctor one day and serve humanity. To study and work hard all day and night seven days a week and gain knowledge in every subject you study. You had taken your life- changing resolution on that first day itself.

I believe in change. I have always tried to explore myself and learn new things each day of my life. That's what we all should do. And not just in the initial days or weeks of the new year. Because you are known by your actions and not what you think.

So stop making resolutions and start taking your real life decisions. Change is the law of nature. Create the change in yourself each passing day for the better. That will make you feel good. And because your ultimate goal in life is not just to be a doctor but also be a good human being. Then one day you will be what you ever wanted to be.

LAP score

Leukocyte Alkaline Phosphatase score is used to differentiate a reactive process from chronic myelogenous leukemia. Here I  just mention the conditions with high and low LAP score (not a mnemonic this time :p )

High lap score:
- Neutrophilia ( as in bacterial infections)
- Polycythemia vera (neoplasm of bone marrow)
- Blast phase of XML
- Hodgkin's disease
- Leukemoid reactions
- in newborns, children and pregnancy.

Low lap score:
- Chronic Myelogenous leukaemia (chronic phase)
- Paroxysmal nocturnal hemoglobinuria
- Hereditary hypophosphatasia

Normal pressure hydrocephalus

Hey awesomites

Normal pressure hydrocephalus is a type of brain malfunction characterised by:
- Dilatation of ventricles
- Distortion of fibres in corona radiata
- Normal pressure on lumbar puncture
- And a triad of symptoms:-
                    - Cognitive loss (dementia)
                    - Apraxia of gait
                    - Pee problems  (urinary incontinence)
I have made a mnemonic for this triad. Since cephalus in hydrocephalus means head so here's a cap to cover it. Mnemonic- CAP

The main aim of treatment in this condition is to drain the excess of CSF. Surgical installation of ventriculoperitoneal shunt is the usual method which aims to drain csf into the peritoneal lining of abdomen from where it is easily absorbed.
