1. What ISMO Retard is and what it is used for
ISMO Retard belongs to a group of medicines
called nitrates. The nitrates make the arteries of
the heart dilate, increasing the blood supply to the
heart muscle.
ISMO Retard is used to treat angina pectoris.
Angina pectoris is a type of chest pain caused
when your heart muscle does not get enough blood
supply. ISMO Retard will help to:
• lower the number of episodes of angina
• lower the severity of your attacks of your angina
2. What you need to know before you take
ISMO Retard
Do NOT take ISMO Retard
• if you are allergic to isosorbide-5-mononitrate
or any of the other ingredients of this medicine
(listed in section 6)
• if you are allergic to isosorbide dinitrate (the
same type of medicine as ISMO Retard)
• if you have marked low blood pressure (systolic
blood pressure ≤ 90 mmHg)
• if you suffer from circulatory collapse or shock
• if you suffer from cardiogenic shock
• if you suffer from acute myocardial infarction
with low left ventricular filling pressure
• if you have been diagnosed with any of the
- hypertrophic obstructive cardiomyopathy
(a thickened heart muscle),
- constrictive pericarditis (an inflammation of
the heart sac),
- cardiac tamponade (accumulation of fluid
around the heart),
- aortic/mitral valve stenosis (narrowing of heart
• if you suffer from severe anaemia (low level of
red blood cells)
• if you suffer from closed angle glaucoma (high
pressure in the eye)
• if you suffer from conditions associated with
raised pressure on the brain (e.g. following
head trauma and cerebral haemorrhage)
• if you suffer from severe hypovolaemia (decreased
blood volume)
• if you are taking sildenafil (as in Viagra ® ),
vardenafil or tadalafil used in the treatment of
male erectile dysfunction (when you cannot get
an erection)
Warnings and precautions
Talk to your doctor or pharmacist before taking
ISMO Retard.
ISMO Retard is used to stop angina attacks from
happening. It is not intended to treat a sudden
attack of angina.
Patients who have not previously received nitrates
may initially be started with a low dose which
should be gradually increased before introducing
ISMO Retard. The lowest effective dose should be
Do not stop taking ISMO Retard suddenly. It
should be withdrawn gradually.
Take special care with ISMO Retard, if
• you suffer from hypothyroidism (your thyroid
gland does not produce sufficient amounts of
thyroid hormone)
• you suffer from malnutrition
• you have severe problems with your liver or
• you have low body temperature (hypothermia)
• you have recent history of myocardial infarction
(heart attack)
• if you are already taking medicine to lower
blood pressure
• you are taking any other medication
• you are pregnant or breast-feeding

If any of the above apply to you, you should
not take this medicine until you have talked
to your doctor about it.
A low blood pressure caused by nitrates may occur
with paradoxical bradycardia (slowing of the heart
rate) and worsening of the symptoms of angina.
A severe drop in blood pressure, when standing up or
move suddenly, with light-headedness and dizziness
is frequently observed after drinking alcohol.
You can develop a tolerance to this medicine or if
you are taking another medicine containing
nitrates. In order to avoid any lessening or loss of
the effect of the medicine, you should not take high
doses on a continual basis.
Taking ISMO Retard may cause transient
hypoxaemia (an abnormally low level of oxygen in
the blood). This happens because blood flow in
your body is redistributed with an increase in
perfusion of poorly ventilated areas of the lung.
This may cause ischaemia (not enough blood going
to your heart muscle) if you have coronary heart
Increasing doses and/or changes in intervals
between doses can lead to this medicine not
working with the effect that it should or not work
at all.
The safety and effectiveness of ISMO Retard in
children has not been established.
Other medicines and ISMO Retard
Tell your doctor or pharmacist if you are taking,
have recently taken or might take any other
Taking the following medicines at the same time
as ISMO Retard can increase the blood pressure
lowering (hypotensive) effect of ISMO Retard:
• other vasodilatators,
• antihypertensives (medicines to treat high blood
pressure) such as ACE-inhibitors, angiotensinII-receptor antagonists, beta-blockers, calcium
antagonists and diuretics,
• neuroleptics (used to treat psychiatric disorders),
• sapropterin (used to lower phenylalanine levels
in the blood of patients with phenylketonuria),
• alprostadil (for male erection problems),
• aldesleukin (for cancer treatment), and
• alcohol
You must not take any treatments for erectile
dysfunction whilst taking ISMO Retard.
Do not take sildenafil (as in Viagra® ), vardanafil
or tadalafil whilst taking ISMO Retard. Treatments for erectile dysfunction can cause a severe
and dangerous fall in blood pressure when taken
together with ISMO Retard. This can be fatal.
ISMO Retard with food, drink and alcohol
Do not drink alcohol whilst taking ISMO Retard as
it may increase the blood pressure lowering
(hypotensive) effect of ISMO Retard.
