5B.2: Why the need <strong>for</strong> Pharmacovigilance in Ghana?<br />
There are differences among countries (and even regions within countries) in the occurrence <strong>of</strong><br />
ADRs and other drug-related problems. This may be due to differences in <strong>for</strong> example:<br />
• Diseases and prescribing practices<br />
• Genetics, diet, traditions <strong>of</strong> the people<br />
• Drug manufacturing processes used which influence pharmaceutical quality and composition<br />
• Drug distribution and use including indications, dose and availability;<br />
• Use <strong>of</strong> traditional and complementary drugs (e.g. herbal remedies) which may pose specific<br />
toxicological problems, when used alone or in combination with other drugs<br />
SP has been shown to be safe and well-tolerated when used <strong>for</strong> IPT. Pharmacovigilance <strong>of</strong> SP in<br />
IPT may also help in detecting other drug related problems including the presence <strong>of</strong> counterfeit<br />
and/or sub-standard quality SP in the country.<br />
5B.3: MONITORING OF SIDE EFFECTS<br />
When given as IPT, SP has been associated with rare severe cutaneous reactions such as toxic<br />
epidermal necrosis and Stevens-Johnson syndrome. However, there is no evidence that the risk<br />
<strong>of</strong> severe cutaneous reactions is any greater in pregnant women than non-pregnant women.<br />
Although sulfonamides are excreted in breast milk, the risk to healthy full-term neonates is<br />
believed to be minimal. Pyrimethamine is usually given in combination with sulphadoxine.<br />
However, studies in which Pyrimethamine has been given alone have also found no increase in<br />
adverse pregnancy outcomes. In addition, Pyrimethamine is considered to be compatible with<br />
breast-feeding.<br />
Several studies have been conducted to detect adverse reactions to SP, including cutaneous<br />
reactions and other potentially serious conditions that would either pose risks to the pregnant<br />
woman or infant or limit programme effectiveness. No evidence has been found <strong>of</strong> increased risk<br />
<strong>for</strong> serious cutaneous side effects or <strong>for</strong> increased jaundice in the newborn when SP has been<br />
administered in the second and third trimesters.<br />
THOUGH DATA ON SAFETY OF SP IS REASSURING, THERE REMAINS AN<br />
ONGOING NEED FOR MONITORING OF SAFETY OF ALL ANTI-MALARIALS USED<br />
FOR TREATMENT AND PREVENTION IN PREGNANCY, INCLUDING SP.<br />
