Interactions between your drugs

Major

captopril venetoclax

Applies to: Capozide 25 / 25 (captopril / hydrochlorothiazide) and venetoclax

GENERALLY AVOID: Coadministration with P-glycoprotein (P-gp) inhibitors may increase the plasma concentrations of venetoclax, which is a substrate of this efflux transporter. Administration of venetoclax with a single dose of rifampin, a P-gp inhibitor when given acutely, increased venetoclax Cmax by 106% and AUC by 78%. Increased venetoclax exposure may potentiate the risk of tumor lysis syndrome, particularly at initiation of therapy and during the dosage ramp-up phase, as well as other adverse effects such as diarrhea, nausea, vomiting, neutropenia, anemia, and thrombocytopenia.

MANAGEMENT: Concomitant use of venetoclax with P-gp inhibitors should generally be avoided. If coadministration is required, the manufacturer recommends that venetoclax dosage be reduced by at least 50%. The dosage used prior to initiating the P-gp inhibitor may be resumed 2 to 3 days after discontinuation of the inhibitor.

captopril hydroCHLOROthiazide

Applies to: Capozide 25 / 25 (captopril / hydrochlorothiazide) and Capozide 25 / 25 (captopril / hydrochlorothiazide)

MONITOR: Although they are frequently combined in clinical practice, diuretics and angiotensin converting enzyme (ACE) inhibitors may have additive effects. Coadministration makes hypotension and hypovolemia more likely than does either drug alone. Some ACE inhibitors may attenuate the increase in the urinary excretion of sodium caused by some loop diuretics. Some patients on diuretics, especially those on dialysis or a dietary salt restriction, may experience acute hypotension with lightheadedness and dizziness after receiving the first dose of the ACE inhibitor. In addition, ACE inhibitors may cause renal insufficiency or acute renal failure in patients with sodium depletion or renal artery stenosis.

MANAGEMENT: Monitoring of blood pressure, diuresis, electrolytes, and renal function is recommended during coadministration. The possibility of first-dose hypotensive effects may be minimized by initiating therapy with small doses of the ACE inhibitor, or either discontinuing the diuretic temporarily or increasing the salt intake approximately one week prior to initiating an ACE inhibitor. Alternatively, the patient may remain under medical supervision for at least two hours after the first dose of the ACE inhibitor, or until blood pressure has stabilized.

Drug and food interactions

Major

venetoclax food

Applies to: venetoclax

ADJUST DOSING INTERVAL: Food enhances the oral bioavailability of venetoclax. Relative to fasting conditions, venetoclax systemic exposure (AUC) increased by approximately 3.4-fold when administered with a low-fat meal and by 5.1- to 5.3-fold when administered with a high-fat meal.

GENERALLY AVOID: Grapefruit juice may increase the plasma concentrations of venetoclax. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruit. In general, the effect of grapefruit juice is concentration-, dose- and preparation-dependent, and can vary widely among brands. Certain preparations of grapefruit juice (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. Increased venetoclax exposure may potentiate the risk of tumor lysis syndrome, particularly at initiation of therapy and during the dosage ramp-up phase, as well as other adverse effects such as diarrhea, nausea, vomiting, neutropenia, anemia, and thrombocytopenia.

MANAGEMENT: Venetoclax should be administered with a meal and water at approximately the same time each day. Patients should avoid consumption of grapefruit products, Seville oranges, and starfruit during treatment with venetoclax.

captopril food

Applies to: Capozide 25 / 25 (captopril / hydrochlorothiazide)

GENERALLY AVOID: Moderate-to-high dietary intake of potassium can cause hyperkalemia in some patients who are using angiotensin converting enzyme (ACE) inhibitors. In some cases, affected patients were using a potassium-rich salt substitute. ACE inhibitors can promote hyperkalemia through inhibition of the renin-aldosterone-angiotensin (RAA) system.

MANAGEMENT: It is recommended that patients who are taking ACE inhibitors be advised to avoid moderately high or high potassium dietary intake. Particular attention should be paid to the potassium content of salt substitutes.

captopril food

Applies to: Capozide 25 / 25 (captopril / hydrochlorothiazide)

MONITOR: Many psychotherapeutic and CNS-active agents (e.g., anxiolytics, sedatives, hypnotics, antidepressants, antipsychotics, opioids, alcohol, muscle relaxants) exhibit hypotensive effects, especially during initiation of therapy and dose escalation. Coadministration with antihypertensives and other hypotensive agents, in particular vasodilators and alpha-blockers, may result in additive effects on blood pressure and orthostasis.

MANAGEMENT: Caution and close monitoring for development of hypotension is advised during coadministration of these agents. Some authorities recommend avoiding alcohol in patients receiving vasodilating antihypertensive drugs. Patients should be advised to avoid rising abruptly from a sitting or recumbent position and to notify their physician if they experience dizziness, lightheadedness, syncope, orthostasis, or tachycardia.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
