The following applies to the ingredients: Quetiapine (found in Seroquel)
Professional Content
GENERALLY AVOID: Grapefruit juice and/or grapefruit may increase the plasma concentrations of quetiapine. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruit. Inhibition of hepatic CYP450 3A4 may also contribute. The interaction has not been studied with grapefruit juice but has been reported for other CYP450 3A4 inhibitors. For example, in 12 healthy volunteers, administration of a single 25 mg dose of quetiapine with the potent CYP450 3A4 inhibitor ketoconazole (200 mg once daily for 4 days) increased mean quetiapine peak plasma concentration (Cmax) and systemic exposure (AUC) by 3.4- and 6.2-fold, respectively, and decreased mean oral clearance by 84%. In general, the effects of grapefruit products are concentration-, dose- and preparation-dependent, and can vary widely among brands. Certain preparations of grapefruit (e.g., high dose, double strength) have sometimes demonstrated potent inhibition of CYP450 3A4, while other preparations (e.g., low dose, single strength) have typically demonstrated moderate inhibition. High plasma levels of quetiapine may increase the risk and/or severity of serious adverse effects such as extrapyramidal symptoms, tardive dyskinesia, hyperglycemia, dyslipidemia, hyperprolactinemia, orthostatic hypotension, blood pressure increases (in children and adolescents), priapism, QT prolongation, cognitive and motor impairment, dysphagia, heat-related illnesses due to disruption of body temperature regulation, and symptoms of serotonin syndrome (e.g., mental status changes such as irritability, altered consciousness, confusion, hallucination, and coma; autonomic dysfunction such as tachycardia, hyperthermia, diaphoresis, shivering, blood pressure lability, and mydriasis; neuromuscular abnormalities such as hyperreflexia, myoclonus, tremor, rigidity, and ataxia; and gastrointestinal symptoms such as abdominal cramping, nausea, vomiting, and diarrhea).
Food may have varying effects on the absorption of quetiapine from immediate-release versus prolonged-release formulations. In a study examining the effects of food on the bioavailability of quetiapine, a high-fat meal was found to produce statistically significant increases in the quetiapine prolonged release Cmax and AUC of approximately 50% and 20%, respectively. It cannot be excluded that the effect of a high fat meal on the formulation may be larger. In comparison, a light meal had no significant effect on the Cmax or AUC of quetiapine.
Quetiapine may potentiate the cognitive and motor effects of alcohol. The mechanism is likely related to the primary central nervous system effects of quetiapine.
MANAGEMENT: According to the manufacturer, consumption of grapefruit juice should be avoided during treatment with quetiapine. Quetiapine immediate-release tablets may be taken with or without food. It is recommended that quetiapine prolonged release is taken once daily without food or with a light meal. Consumption of alcohol should be limited and used with caution while taking quetiapine.

Lisinopril
+ Pregnancy
The following applies to the ingredients: Lisinopril
Professional Content
AU: Use is contraindicated.
UK: Use is not recommended during the first trimester and use is contraindicated during the second and third trimesters.
US: This drug should not be used during pregnancy unless there are no alternatives and the benefit outweighs the risk to the fetus.
AU TGA pregnancy category: D
US FDA pregnancy category: Not assigned
Risk Summary: Use of drugs that act on the renin angiotensin system (RAS) during the second and third trimesters of pregnancy increases fetal and neonatal morbidity and death.
Comments:
-Adequate methods of contraception should be encouraged.
-Advise pregnant women and females of reproductive potential of the potential risk to a fetus.
Animal studies have revealed evidence of fetotoxicity. In humans, exposure to angiotensin-converting enzyme (ACE) inhibitors during the second and third trimesters has revealed evidence of fetal and neonatal toxicity and fetolethality. There are no controlled data in human pregnancy.
AU TGA pregnancy category D: Drugs which have caused, are suspected to have caused or may be expected to cause, an increased incidence of human fetal malformations or irreversible damage. These drugs may also have adverse pharmacological effects. Accompanying texts should be consulted for further details.
US FDA pregnancy category Not Assigned: The US FDA has amended the pregnancy labeling rule for prescription drug products to require labeling that includes a summary of risk, a discussion of the data supporting that summary, and relevant information to help health care providers make prescribing decisions and counsel women about the use of drugs during pregnancy. Pregnancy categories A, B, C, D, and X are being phased out.

Safety has not been established during pregnancy.
AU TGA pregnancy category: C
US FDA pregnancy category: Not assigned
Risk summary: No data are available on the use of this drug in pregnant women to inform a drug-related risk.
Comments:
-A pregnancy exposure registry is available.
-If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential harm to the fetus.
-Neonates exposed to antipsychotic drugs during the third trimester of pregnancy are at risk for extrapyramidal and/or withdrawal symptoms following delivery.
Animal studies have revealed evidence of embryo-fetal toxicity. Limited published human data have reported no major malformations associated with use during pregnancy. There are no controlled data in human pregnancy.
Neonates exposed to antipsychotic drugs during the third trimester of pregnancy are at risk for extrapyramidal and/or withdrawal symptoms following delivery. There have been reports of agitation, hypertonia, hypotonia, tremor, somnolence, respiratory distress and feeding disorder in these neonates. These complications have varied in severity; while in some cases symptoms have been self-limited, in other cases neonates have required intensive care unit support and prolonged hospitalization.
To monitor the outcomes of pregnant women exposed to atypical antipsychotics, a National Pregnancy Registry for Atypical Antipsychotics has been established. Physicians are encouraged to register patients and pregnant women are encouraged to register themselves. For additional information: https://womensmentalhealth.org/clinical-and-research-programs/pregnancyregistry/.
AU TGA pregnancy category C: Drugs which, owing to their pharmacological effects, have caused or may be suspected of causing, harmful effects on the human fetus or neonate without causing malformations. These effects may be reversible. Accompanying texts should be consulted for further details.
US FDA pregnancy category Not Assigned: The US FDA has amended the pregnancy labeling rule for prescription drug products to require labeling that includes a summary of risk, a discussion of the data supporting that summary, and relevant information to help health care providers make prescribing decisions and counsel women about the use of drugs during pregnancy.

+ Breastfeeding
The following applies to the ingredients: Quetiapine (found in Seroquel)
Professional Content
Use is not recommended, and a decision should be made to discontinue breastfeeding or discontinue the drug, taking into account the importance of the drug to the mother.
Excreted into human milk: Yes
Comments:
-If this drug is used, monitor infants for drowsiness and developmental milestones.
-The American Academy of Pediatrics classified other antipsychotic agents as drugs whose effect on the nursing infant is unknown but may be of concern.
Based on milk samples from a mother who received 200 mg daily throughout pregnancy and postpartum, it is estimated that an exclusively breastfed infant would receive 0.09% to 0.43% of a weight-adjusted maternal dose. Limited long-term follow-up of infants exposed to this drug during breastfeeding have shown generally normal development. However, due to the potential for serious adverse reactions in nursing infants and a lack of robust data, a decision should be made to discontinue breastfeeding or discontinue the drug, taking into account the importance of the drug to the mother.
