Interaction Details
Acetaminophen, Chlorpheniramine, Dextromethorphan, Phenylpropanolamine is classified as belonging to the following category: Cytochrome P450 2D6 (Cyp2D6) Substrates
Beta-methylphenylethylamine (BMPEA), a constituent found in some Acacia rigidula products, strongly inhibits cytochrome P450 2D6 (CYP2D6) enzymes in vitro. Theoretically, Acacia rigidula might increase the levels of CYP2D6 substrates. Some of drugs that are CYP2D6 substrates include amitriptyline (Elavil), clozapine (Clozaril), codeine, desipramine (Norpramin), donepezil (Aricept), fentanyl (Duragesic), flecainide (Tambocor), fluoxetine (Prozac), meperidine (Demerol), methadone (Dolophine), metoprolol (Lopressor, Toprol XL), olanzapine (Zyprexa), ondansetron (Zofran), tramadol (Ultram), trazodone (Desyrel), and others.

Interaction Details
Acetaminophen, Chlorpheniramine, Dextromethorphan, Phenylpropanolamine is classified as belonging to the following category: Cytochrome P450 3A4 (Cyp3A4) Substrates
Beta-methylphenylethylamine (BMPEA), a constituent found in some Acacia rigidula products, inhibits cytochrome P450 3A4 (CYP3A4) enzymes in vitro by 37%. Theoretically, Acacia rigidula might increase the levels of CYP3A4 substrates. Drugs that might be affected include some calcium channel blockers (diltiazem, nicardipine, verapamil), chemotherapeutic agents (etoposide, paclitaxel, vinblastine, vincristine, vindesine), antifungals (ketoconazole, itraconazole), glucocorticoids, cisapride (Propulsid), alfentanil (Alfenta), fentanyl (Sublimaze), losartan (Cozaar), fluoxetine (Prozac), midazolam (Versed), omeprazole (Prilosec), ondansetron (Zofran), propranolol (Inderal), fexofenadine (Allegra), and numerous others.

Interaction Details
Acetaminophen, Chlorpheniramine, Dextromethorphan, Phenylpropanolamine is classified as belonging to the following category: Stimulant Drugs
Constituents isolated from Acacia rigidula are thought to have stimulant effects. Additionally, dietary supplements listing Acacia rigidula as an ingredient have been shown to contain the stimulant beta-methylphenethylamine and greater amounts of other stimulant compounds than would normally be found in plant parts. Theoretically, taking Acacia rigidula with stimulant drugs might increase the risk of adverse cardiovascular effects.
Some stimulant drugs include amphetamine, caffeine, diethylpropion (Tenuate), methylphenidate, phentermine (Ionamin), pseudoephedrine (Sudafed, others), and many others.

Acacia Rigidula Overview
Acacia rigidula is a species of acacia tree native to Texas and Mexico. The plant is known for its small, bright yellow flowers and its woody, thorny branches.
Acacia rigidula has been traditionally used for medicinal purposes and is available as a dietary supplement marketed for weight loss aid and as a stimulant. It is purported to boost energy, increase metabolism, and aid weight loss.
Studies have found several active compounds in Acacia rigidula, including phenylethylamine (PEA) and its derivatives, which are considered to be stimulants.
