Anti -thyroid

Hyperthyroidism

1) Thioamides - carbimazole, propylthiouracil, methimazole --> block synthesis of thyroid hormone
How to start??
starts at a high daily dose of 15 - 40mg continued until the patient has normal thyroid function. Then reduced to a maintenance dose of 5 - 15mg.
Treatment is usually given for 12 - 18 months followed by a trial withdraw
SE : rashes & pruritus --> if due to carbimazole cn change to PTU
bone marrow suppression (ask patient to come if has fever,sore throat)- Monitor WBC 3monthly
PTU can also cause fulminant liver failure --> death
PTU & methimazole - use in pregnancy. PTU (1st trimester) da rest is methimazole

2) Beta blocker - adrenoreceptor blocker
treat tremor & tachycardia

3) radioactive iodine (131 - I)
MOA : incorporate into storage follicles & destroy tissue internally

4) Iodide replacement agent (pottasium iodide)
MOA : inhibit thyroglobulin proteolysis --> inh hormone release --> decrease overactivity of thyroid

Hypothyroidism

Levothyroxine (synthetic T4) , Liothyronine (synthetic T3)
MOA : actions as endogenous hormone. enter cells, convert T4 to T3, T3 enter nucleus, bind to specific receptor protein, activate the synthesis

Anti Hypertensive

1) Beta Blocker
MOA : Sympatholytic at Beta 1 & Beta 2 adrenoreceptor, inhibit NE at the synapse
Drugs : Propanolol, cardioselective Beta 1 antagonist :Metonolol, atenolol
SE : Bradycardia, bronchospasm, hallucinations, muscle weakness

2) Alpha blocker (seldom use in hypertension, use for BPH)
MOA : Alpha adrenoreceptor blocker cause vasodilatation
Drugs : Prazosin, Terazosin

3) Alpha & beta blocker (use in pre eclampsia / emergency treatment of hypertension)
MOA: Block alpha & beta adrenoreceptor & cause decrease in peripheral vascular resistance leads to reduction in BP
Drugs: Labetolol
SE : Drowsiness, bradycardia, complete heartblock, bronchoconstriction, pulmonary edema
Relative Contraindication : asthma, heart failure, any degree of heart block

4) ACEI
MOA : vasodilator as angiotensin is potent vasoconstrictor. ACEI inhibit conversion of angiotensin 1 to angiotensin II by ACE
Drugs : Captopril, enalapril
SE : hyperkalemia, dry cough, hypotension, postural hypotension, angioedema
Contraindication : Renal artery stenosis, pregnancy, impaired renal function

5) Angiotensin receptor blocker (ARB)
MOA: AT1-receptor antagonists. Block the activation of angiotensin II AT1 receptor on vessels which directly causes vasodilatation, reduces secretion of vasopressin, reduces production and secretion of aldosterone
Drugs : losartan, valsartan, telmisartan
SE : Dizziness, headache, hyperkalemia, postural hypotension on first dose

6) Calcium channel blocker (CCB)
MOA: Block entry of calcium through calcium channel in the smooth muscle of endothelium cause it to relax & vasodilatation
Drugs:
Dihydropyridine (Nifedipine, amlodipine)
Nondihydropyridine (verapamil, diltiazem) --> reduce myocardial oxygen demand & reverse coronary spasm
SE: Dihydropyridine - reflex tachycardia, leg edemadizziness,headache
Non-dihydropyridine - arrythmias
CI ; can worse proteinuria in pt with nephropathy

7) Direct Vasodilator
MOA : at local level. Nitric oxide - potent vasodilator, enhance action of NO direct at vessels
Drugs : Hydralazine, Minoxidil, Na nitroprusside
SE : Hypotension, headache, Tachycardia, tachyphylaxis

8) Centrally acting drugs
MOA : affect on CNS & sympathetic NS
Drugs : clonidine - use or migraine
Methyldopa - safest to use in pregnancy
SE: dizzinessm postural hypotension

9) Diuretics
a) Thiazide (chlorothiazide, indapamide)
MOA: inh reabsorption of Na & K at distal tubule
SE : hypokalemia, metabolic alkalosis, hyperurecemia, hyperglycemia
CI : gout

b) Carbonic anhydrase Inhibitor (CAI) - acetazolamide - use for acute glaucoma
MOA : Inh reabsorption of NaHCO3- at proximal tubule
SE : hypokalemia, metabolic acidosis, hypersensitivity

c) Loop Diuretics - Furusemide, Bumetanide, Ethacrynic acid
MOA : Inh reabsorption of Na, Cl, K at THICK ASCENDING Loop of HenLe & increase renal blood flow by cortical vasodilatation
SE : hypokalemia, metabolic alkalosis, postural hypotension

d) Pottassium sparing - spironolactone
MOA : Aldosterone antagonist - inhibit action of aldosterone at distal tubule & collecting duct
SE : hyperkalemia, metabolic acidosis, gynecomastia

10) Renin inhibitor - Aliskiren
MOA : act on the Juxtaglomerular cells of kidney, which produce renin in response to decreased blood flow
SE : hyperkalemia, hypotension, angioedema

DAY 1 - Be Strong~

Tomorrow Is The Day. Today is My last day to recap most that Ive studied before. Please pray that I make it this time. There is a limit to a person's strength.

But for now, I just want to do my best, prepare the best that I can, be positive, be SUPER happy, MEGA happy, have INFINITE happiness & the rest I leave it to Allah. Human has so much limitations. Just live with it & be happy with it.

Allah knows best for me. I always believe Allah will definitely help those who ask for his help & those inneed~

Akhir kata. benarlah kata-kata Allah (Always believe in his promises) =)

Sayang, hanya ada satu gambar sahaja. Huhu~ Selebihnya ada di rumah pula~

Seronok melihatkan gambar-gambar ini. Teringat betapa gembiranya saya pada ketika itu. Eh, tak bermakna sekarang saya tidak gembira. Gembira juga~ hehe

DAY 3 - THE ROAD

With just a glimpse (5months ago), the road seems to be rough & bumpy with no ends to it.....


Yeah, definitely the journey requires a lot of works & sacrifices.........


Need to juggle between so many things~

KeLetiHaN~


Hati tenanglah dikau, setenang awan di langit~

Sangat bersyukur setiap hari kerana Allah sangat memudahkan urusan saya. Positiviti yang saya ada sangat-sangat membantu & makin sampai kepenghujung, terbit pula rasa sayang nak tinggalkan lecturer2 & UIA.

Dalam semangat untuk meneruskan saki-baki perjuangan, mula merasakan kepenatan yang mula melanda diri. Sebelum ini ada study group, jadinya bila kita penat, kawan-kawan yang tolong ajar & turn kita mendengar & bergilir-gilir dalam berkongsi ilmu. Tetapi sekarang tidak lagi, semuanya harus diusahakan sendiri & hanya kepada Allah saya memohon pertolongan.

Manusia kudratnya sangat terbatas. Apabila kita menginginkan sesuatu, memang kita menggunakan kudrat kita, tetapi siapa yang membenarkan setiap otot-otot kita ini berfungsi??Siapa yang membenarkan sel-sel otak kita memainkan peranan??Semuanya daripada ALLAH kan~

Jadinya, have fun & teruskan usaha & bergembiralah dengan apa yang kamu ada =)

Sikit-sikit kan lama-lama jadi bukit~ hehe

"Ya Allah~ kau lembutkanlah hati examiner2ku nanti~ "
