2.MoA:
3.Examples:
4.Adverse effects:
5.Contraindications:
6.Drug-drug interactions:
- Calcium channel blockers that are selective for peripheral vasculature
2.). Block calcium channels preventing Ca2+ influx into cells preventing contraction of smooth muscle
3.) amlodipine, nimodipine (selective for cerbreal vasculature so given in subarachnoid haemorrrhage)
4.) ankle swelling, flushing, headaches (vasodilation), palpitations
5.) unstable angina, severe aortic stenosis, cardio genic shock

2.MoA:
3.Examples:
4.Adverse effects:
5.Contraindications:
6.Drug-drug interactions:
- Class IV antiarrythtmic agent since its a type of Calcium CHannel blocker which prolongs the action potential and effective refractory period
Used for arrhythmia and angina, hypertension - Targets mainly the heart so negative chronotropy and inotropy since reduces CA2+ influx into heart
- Verapamil
- Constipation, bradycardia, Hearst block an cardiac failure
- Poor LV function, AVN conduction delay
- B blockers and caution with other anti hypertensives and antiarrythmic pus
- What are Thiazides/thiazide like diuretics /what are they used for?
2.MoA:
3.Examples:
4.Adverse effects:
5.Contraindications:
6.Drug-drug interactions:
Diuretics used when oedema, hypertension
Blocks Na+/Cl- Cotransporter at DCT causing in creased osmolarity in the filtrate so more water and sodium is lost in the urine
3.) indapamide, bendroflumethiazide
- Hypokalemia, hyponatraemia, hyperuricemia, arrhythmia, inc glucose, cholesterol and TG
- Hypokalaemia, hyponatraemia, gout
- NSAIDs, K+ losing drugs like loop diuretics
- What are aldosterone receptor antagonists/what are they used for?
2.MoA:
3.Examples:
4.Adverse effects:
5.Contraindications:
6.Drug-drug interactions:
- Type of diuretic/antihypertenisve, used when other hypertensive drugs haven’t worked
2.) blocks the aldosterone receptors so the action for aldosterone is not experienced (ENAC not upregulated so Na= stays in filtrate and K+ stays in the body at kidneys) - Spironolactone
- Hyperkalaemia, gynaecomastia
5.hyper kalaemia,addisons disease - K+. Sparring drugs, pregnancy
- What are B-blockers/what are they used for?
2.MoA:
3.Examples:
4.Adverse effects:
5.Contraindications:
6.Drug-drug interactions:
1.). Reduce cardiac output so good for HF, hypertension
2. Decrease sympathetic tone by blocking Noradrenaline binding to B receptors and reduces myocardial contraction strength and speed
- Bisoprolol, propranolol, Alberta lol, metoprolol
- Bronchospasm, heart block, Raynauds, lethargy, impotence, masks tachycardia which is a sign of insulin induced hypoglycaemia
- Asthma, COPD, haemodynamic instability, hepatic failure
- Non dihydropyridine CCBs like verapamil and diltiazem cause asystole
- What are alpha blockers/what are they used for?
2.MoA:
3.Examples:
4.Adverse effects:
5.Contraindications:
6.Drug-drug interactions:
- Selective antagonism of a1 adrenoceptors that reduce peripheral vascular resistance , helps treat BPH
2.) selectively binds to alpha 1 adrenoceptors preventing Noradrenaline binding so vessels dont vasoconstriction
3.) doxazosin, tamsulosin (BPH)
4. Postural hypotension, dizziness, syncope, headache and fatigue
5 postural hypotension
6. Patients on dihydropyriridne CCB since will increase oedema
- What are loop diuretics/what are they used for?
2.MoA:
3.Examples:
4.Adverse effects:,
5.Contraindications:
6.Drug-drug interactions:
- Type of diuretic used in pulmonary oedema, fluid overload in HF, nephrotic syndrome
- Inhibits NKCC channel ini LoH so increased osmolarity in the filtrate so more water excreted, also direct dilation of capacitance veins reducing preload
- Furosemide, bumetanide
- Dehydration, hypotension, hypokalaemia, hyponatraemia, hyperuricaemia , tinnitus = Ototoxic, inc cholesterol and TG
- Hypokalaemia, hyponatraemia, gout, hepatic encephalopathy
- Aminoglycosides like gentamicin, digoxin and lithium since all Ototoxic

2.MoA:
3.Examples:
4.Adverse effects:,
5.Contraindications:
6.Drug-drug interactions:
