#CYP3A4 inhibitors

[mcatmemoranda]

Anticoagulation Lecture 6/21/23

Factor Xa inhibitors = rivaroxaban, apixaban (Eliquis)

Direct thrombin inhibitor = dabigatran

Vitamin K inhibitor = warfarin

Apixaban has the lowest bleeding risk compared to the other Direct Oral Anticoagulants (DOACs); avoid in pts with BMI greater than or equal to 40 or weight more than 120 kg. Avoid dual inhibitors or inducers of CYP3A4 and P-gp.

VTE/PE tx = 10mg bid x7 days, then 5 mg bid

AFib = 5 mg bid (reduce to 2.5 mg bid if Cr greater than or equal to 1.5 or weight less than 60 kg or age greater than 80

Rivaroxaban (Xarelto) = once daily dosing compared to Eliquis

VTE/PE: 15 mg bid x21 days; then 20 mg qd

AFib: 20 mg qd with food to increase absorption

PAD/CAD: 2.5 mg bid (+antiplatelets if at increased risk)

Avoid with CYP3A4 inhibitors or inducers and P-gp

Edoxaban (Savaysa) – not used in pts with CrCl greater than 95

VTE/PE = parenteral anticoagulation for 5-10 days, then PO

VTE/PE/AFib = 60 mg qd

Does not have reversal agent like other DOACs do (which are reversed with Kcentra or andexanet)

Dabigatran (Pradaxa)

AFib: 150 mg bid; consider 110 mg bid if bleeding risk

VTE/PE: 5 days IV, then 150 mg bid

VTE ppx after THA/TKA: initial 110 mg once, then 220 mg qd x10-35 days

5-10 day bridge required for PE/VTE

Caution in pts greater than 75 years due to increased bleeding risk

Has own reversal agent (praxbind; idarucizumab)

C/I in pts with prosthetic heart valve

Store in original bottle and discard if unused after 4 months

Eliquis and Xarelto can be crushed and given via feeding tubes.

Warfarin (Coumadin)

Dosing is pt specific. Goal INR is 2-3. (2.5-3.5 if mechanical mitral valve).

Slow onset; slow time to steady state means dose taken today may not be reflected in INR for several days (2-4 days).

So many drug-drug interactions!

Metabolized by CYP pathways

Vitamin K antagonist

Dosing: recommend taking at night because INR is taken during the day, makes it easier to adjust dose.

Warfarin’s therapeutic steady state is based on half-lives of clotting factors. At least 5 days of consecutive warfarin needed for pt to be fully anticoagulated (this is why you use heparin until they get to this point).

Usually start with 5 mg qd. If bleeding risk, start with 2.5 mg qd. For obese pts or otherwise healthy/young can start with 7.5 mg qd. You go to maintenance protocol on 7th day.

Pts on VTE/PE tx are not anticoagulated the first 5 days, so use heparin IV or LMWH outpt. Once anticoagulated x24 hours, d/c heparin.

Start with 5 mg warfarin for first 3 days, then follow up with warfarin clinic on day 4. Typically, pt goes for weekly INRs. Then when at goal INR for 2 weeks, can spread out how often they f/u on their INR levels. Eventually they can go q6-8 weeks to check INR level.

VTE/PE – always bridge

AFib – risk assess to see whether heparin bridging is needed (assess bleeding risk [HASBLED]; CHA2DS2VASc for thrombotic risk).

Every 10 years, the dosing needed will decrease by 10%, so as pts age, the dose of warfarin needed will decrease.

DOACs = no INR monitoring, no dietary interactions, lower rates of bleeding, limited availability of reversal agent; contraindicated in pts with mechanical heart valves

AFib – AC (anticoagulate) indefinitely

1st VTE or PE that is provoked – AC for 3 months

1st episode of VTE/PE in setting of cancer – 3 months of AC (LMWH is better than DOAC or warfarin--new research shows DOAC may actually be more effective, so can use DOAC now; LMWH not preferred)

1st episode of VTE/PE unprovoked (no idea what caused it) – AC more than or equal to 3 months

2nd VTE – AC indefinitely

Heparin reversal – protamine (max dose is 50 mg), to reverse enoxaparin, give 1 mg protamine for each 1 mg of Lovenox

Warfarin reversal – vit K; 4 factor prothrombin compex (KCentra); FFP (if KCentra not available); KCentra is for life-threatening bleeding or if pt needs surgery for life-threatening condition

Apixaban/Rivaroxaban reversal – Kcentra (life threatening bleed or need emergency surgery; has thrombotic risk); FFP (Fresh Frozen Plasma); Andexanet Alfa. KCentra can cause clotting in 5% of pts; don’t give if you don’t need to.

Dabigatran reversal – idarucizumab (Praxbind); dosed as 5 g IV given 2.5 mg no more than 15 minutes apart)

Heparin lasts 2 hours

LMWH is preferred in pts who are pregnant (avoid warfarin). ESRD on dialysis – warfarin or Eliquis (avoid Xarelto). Obese pts – DOACs or warfarin. Cancer – use LMWH; recent study shows Eliquis is equal to or superior to LMWH in cancer pts who need anticoagulation.

Pregnancy = lovenox better, doesn’t cross placenta; UFH (unfractionated heparin) is an alternative in pts with poor renal function.

Stop heparin gtt and give Eliquis now or give 2 hours after stopping heparin gtt. Give loading dose Eliquis even if the pt was on heparin gtt.

fwiw my physiotherapist told me that people with eds apparently metabolise things faster than other people, so your fast metabolisation of medications/caffeine/etc could be in part linked to that?

yes people with EDS (and other forms of chronic pain) are highly likely to have the abnormal liver enzyme thing

we don't really know *why* but it's just. a thing.

The most common side effect of finerenone is hyperkalemia, which you could guess from its mechanism of action. This can be reduced by concommitant administration of a potassium waster like furosemide or an SGLT2 inhibitor. Other potential side effects include hypotension and hyponatremia. Because strong CYP3A4 inhibitors increase finerenone levels, don't take with grapefruit (juice), and monitor K levels when given with other possible offenders. Avoid in patients with severe liver disease (Child-Pugh C, and maybe B). Finerenone is found in breast milk. It does not cause AKI. Image: American Journal of Managed Care

Resihance

Regorafenib   is a multi-kinase inhibitor used primarily for the treatment of cancer. It is particularly effective in targeting angiogenesis (the formation of new blood vessels), which plays a crucial role in cancer growth and metastasis. Below is a detailed overview of Regorafenib:

Mechanism of Action:

Regorafenib inhibits multiple protein kinases involved in tumor angiogenesis, oncogenesis, and the tumor microenvironment. Specifically, it targets:

VEGFR (Vascular Endothelial Growth Factor Receptor) – involved in blood vessel formation.

PDGFR (Platelet-Derived Growth Factor Receptor) – involved in the growth and survival of cells.

RAF kinases (including BRAF) – involved in cell proliferation and survival.

By blocking these pathways, Regorafenib reduces tumor growth and the spread of cancer.

Indications:

Regorafenib is used in the treatment of several cancers, including:

Colorectal Cancer: It is used in metastatic colorectal cancer (mCRC) that has progressed after standard therapy.

Gastrointestinal Stromal Tumors (GIST): It is prescribed for GIST after imatinib and sunitinib treatment have failed.

Hepatocellular Carcinoma (HCC): For patients with advanced liver cancer who have been previously treated with sorafenib.

Common Side Effects:

Fatigue

Hand-foot skin reaction (redness, swelling, pain in palms and soles)

Diarrhea

Hypertension (high blood pressure)

Nausea and vomiting

Abdominal pain

Decreased appetite

Weight loss

Serious Side Effects:

Liver toxicity: Regorafenib can lead to severe liver damage, including elevated liver enzymes, jaundice, and, in rare cases, liver failure.

Bleeding: Regorafenib can increase the risk of severe bleeding, especially in patients with cancer that has spread to the liver.

Cardiovascular complications: It can lead to high blood pressure and may increase the risk of heart attack or stroke.

Gastrointestinal perforation: A rare but potentially life-threatening complication.

Monitoring and Precautions:

Liver function should be monitored regularly because of the risk of liver toxicity.

Blood pressure should be checked frequently to detect any early signs of hypertension.

Skin reactions should be monitored closely, as they can affect the patient's quality of life.

Kidney function should also be assessed periodically, especially in patients at risk of kidney damage.

Pharmacokinetics:

Absorption: Regorafenib is well absorbed after oral administration but should be taken with a low-fat meal to ensure proper absorption.

Metabolism: The drug is metabolized in the liver primarily through CYP3A4, and its active metabolites also play a role in its efficacy.

Excretion: Regorafenib and its metabolites are excreted primarily through feces, with a small portion eliminated through urine.

Attend the speech of "Dr. Juliana Bicca" about “Estrogen Metabolism And Women´S Health: Implications For Disease And Therapeutic Interventions” at the 14GASTROUCG

Estrogen, a primary female sex hormone, plays a critical role in women's health. Beyond its well-known effects on reproductive tissues, estrogen influences various physiological systems, including the cardiovascular, skeletal, and central nervous systems. Understanding estrogen metabolism is crucial for appreciating its implications for women's health and developing effective therapeutic interventions. This blog delves into the intricate world of estrogen metabolism, its impact on health, and potential therapeutic approaches.

The Basics of Estrogen Metabolism

Estrogen metabolism involves the conversion of estrogens, such as estradiol, into various metabolites. This process primarily occurs in the liver through a series of enzymatic reactions. The key players in estrogen metabolism include:

Aromatase: This enzyme converts androgens (male hormones) into estrogens, making it pivotal in regulating estrogen levels.

CYP450 Enzymes: Cytochrome P450 enzymes, particularly CYP1A1, CYP1B1, and CYP3A4, are responsible for hydroxylating estrogens. These reactions produce various metabolites, including 2-hydroxyestrone and 16α-hydroxyestrone, with differing biological activities.

COMT (Catechol-O-Methyltransferase): This enzyme methylates hydroxylated estrogen metabolites, rendering them less active and more easily excreted.

Implications of Estrogen Metabolism on Women's Health

Breast Cancer: The balance between different estrogen metabolites can influence breast cancer risk. For example, 16α-hydroxyestrone has been associated with a higher risk, while 2-hydroxyestrone is considered less estrogenic and may have protective effects. Understanding these pathways can help in assessing risk and developing preventive strategies.

Bone Health: Estrogen plays a crucial role in maintaining bone density. During menopause, the decline in estrogen levels can lead to increased bone resorption, contributing to osteoporosis. Estrogen replacement therapies can help mitigate this risk, but understanding individual metabolic pathways is vital for personalizing treatment.

Cardiovascular Health: Estrogen has protective effects on the cardiovascular system, including promoting vasodilation and reducing cholesterol levels. However, its metabolism can produce metabolites with different effects, influencing cardiovascular risk. For instance, some metabolites may increase oxidative stress, while others have antioxidant properties.

Neuroprotection: Estrogen's role in the central nervous system includes neuroprotective effects, potentially lowering the risk of neurodegenerative diseases like Alzheimer's. However, the benefits may vary depending on the balance of estrogen metabolites.

Therapeutic Interventions and Considerations

Hormone Replacement Therapy (HRT): HRT is commonly used to alleviate menopausal symptoms and prevent osteoporosis. However, the type of estrogen and the metabolic pathways it engages are crucial in determining the therapy's safety and efficacy. For instance, bioidentical hormones may offer a more favorable risk profile compared to synthetic hormones.

Selective Estrogen Receptor Modulators (SERMs): SERMs are compounds that selectively activate or block estrogen receptors in different tissues. They can be used to mimic the beneficial effects of estrogen in some tissues while avoiding adverse effects in others, such as breast tissue.

Aromatase Inhibitors: These drugs inhibit the aromatase enzyme, reducing estrogen production. They are often used in treating estrogen receptor-positive breast cancer, as they lower estrogen levels and limit tumor growth.

Nutritional and Lifestyle Interventions: Diet and lifestyle can significantly impact estrogen metabolism. For example, cruciferous vegetables contain compounds that can promote the formation of beneficial estrogen metabolites. Regular exercise and maintaining a healthy weight also positively influence hormone balance.

Conclusion

Estrogen metabolism is a complex but crucial aspect of women's health, influencing a wide range of physiological processes and disease risks. As our understanding of these metabolic pathways grows, it opens new avenues for personalized medicine and targeted therapies. By considering individual differences in estrogen metabolism, healthcare providers can offer more tailored and effective treatments, ultimately improving women's health outcomes. Whether through pharmacological interventions, lifestyle changes, or a combination of both, the goal remains to harness the benefits of estrogen while minimizing potential risks.

Unraveling the Interactions: Aspirin's Influence on Drug Metabolism and Therapy

Aspirin, a ubiquitous medication renowned for its pain-relieving and anti-inflammatory properties, has a long-standing history of medical use. Beyond its primary indications, recent research has shed light on its potential impact on the metabolism and efficacy of various drugs. Understanding these interactions is crucial for optimizing therapeutic outcomes and mitigating potential risks associated with polypharmacy.

Interactions with Drug Metabolism:

Aspirin’s Influence on Drug, also known as acetylsalicylic acid, exerts its effects through inhibition of cyclooxygenase enzymes, particularly COX-1 and COX-2. While primarily recognized for its antiplatelet and analgesic actions, aspirin's influence extends to drug metabolism pathways mediated by cytochrome P450 enzymes (CYPs). Studies have demonstrated that aspirin can modulate the activity of certain CYP isoforms, potentially altering the pharmacokinetics of co-administered drugs. Specifically, aspirin has been implicated in inhibiting CYP2C9, CYP2C19, and CYP3A4 enzymes, which are involved in the metabolism of a wide array of medications, including anticoagulants, antiplatelet agents, statins, and selective serotonin reuptake inhibitors (SSRIs).

Clinical Implications:

The interactions between aspirin and other drugs carry significant clinical implications. For instance, concurrent use of aspirin with anticoagulants like warfarin or direct oral anticoagulants (DOACs) may potentiate the risk of bleeding due to impaired metabolism of these agents. Similarly, co-administration of Aspirin’s Influence on Drug with certain antidepressants, such as fluoxetine or sertraline, may lead to elevated drug concentrations and an increased risk of adverse effects. Furthermore, the impact of aspirin on antiplatelet agents like clopidogrel underscores the importance of tailored therapy regimens to balance efficacy and safety in patients with cardiovascular conditions.

Future Directions:

While current evidence elucidates some of the interactions between aspirin and other drugs, further research is warranted to comprehensively characterize these phenomena. Future studies should explore the molecular mechanisms underlying aspirin-mediated alterations in drug metabolism and assess the clinical relevance of these interactions across diverse patient populations. Additionally, advances in pharmacogenomics may facilitate personalized approaches to drug therapy, considering individual variations in enzyme activity and drug response.

Conclusion:

In conclusion, aspirin's influence on drug metabolism presents a multifaceted phenomenon with implications for therapeutic efficacy and safety. Clinicians should remain vigilant when prescribing aspirin in conjunction with other medications, considering potential interactions that may impact treatment outcomes. Continued research efforts are essential to refine our understanding of these interactions and optimize pharmacotherapeutic strategies in clinical practice.

How effective is Finerenone?

New medicine for treating diabetic nephropathy – LUCIFINE finerenone tablets

LUCIFINE Finerenone Tablets Is a non-steroidal mineralocorticoid receptor antagonist (MRA) indicated to reduce the risk of sustained eGFR decline end stage kidney disease, cardiovascular death non-fatal myocardial infarction, and hospitalization for hear failure in adult patients with chronic kidney disease(CKD) associated with type 2 diabetes T2D)

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of a drug and may not reflect the rates observed in practice.

The safety of LUCIFINE was evaluated in 2 randomized, double-blind, placebo-controlled, multicenter pivotal phase 3 studies, FIDELIO-DKD and FIGARO-DKDin which a total of 6510 patients were treated with 10 or 20 mg once daily over a mean duration of 2.2 and 2.9 years, respectively.

Overall, serious adverse events occurred in 32% of patients receiving LUCIFINE and in 34% of patients receiving placebo in the FIDELIO-DKD study: the findings were similar in the FIGARODKD study. Permanent discontinuations due to adverse events also occurred in a similar proportion of patients in the two studies (6-7% of patients receiving LUCIFINE and in 5-6% of patients receiving placebo).

The most frequently reported (≥10%）adverse reaction in both studies was hyperkalemia [see Warnings and Precautions(5.1)]. Hospitalization due to Hyperkalemia for the LUCIFINE was 0.9% vs 0.2% in the placebo group across both studies. Hyperkalemia led to permanent discontinuation of treatment in 1.7% receiving LUCIFINE versus 0.6% of patients receiving placebo across both studies.

LUCIFINE is a CYP3A4 substrate. Concomitant use with a strong CYP3A4 inhibitor increases Finerenone exposure, which may increase the risk of LUCIFINE adverse reactions. Concomitant Use of LUCIFINE with strong CYP3A4 inhibitors is contraindicated see Contraindications (4) Avoid concomitant intake of grapefruit or grapefruit juice.

Moderate and Weak CYP3A4 Inhibitors LUCIFINE is a CYP3A4 substrate. Concomitant use with a moderate or weak CYP3A4 inhibitor increases Finerenone exposure, which may increase the risk of LUCIFINE adverse reactions. Monitor serum potassium during drug initiation or dosage adjustment of either LUCIFINE or the moderate or weak CYP3A4 inhibitor, and adjust LUCIFINE dosage as appropriate [(see Dosing and Administration (2.3) and Drug interaction (7 .2)]. Strong and Moderate CYP3A4 inducers.

LUCIFINE is a CYP3A4 substrate. Concomitant use of LUCIFINE with a strong or moderate CYP3A4 inducer decreases Finerenone exposure. which may reduce the efficacy of LUCIFINE. Avoid concomitant use of LUCIFINE with strong or moderate CYP3A4 inducers.

Purchase Sildenafil Tablets On-line

Some brands of sildenafil tablets are scored to allow them to be reduce or damaged in two easily. Other brands are un-scored and may be difficult to split with out shattering. Generic medicines supplied sidena 50mg might change from time to time as producers could have inventory shortages, and generic producer switching is usually unavoidable.

Some prescribed medicines interact with sildenafil, most notably medicines known as nitrates, used to deal with angina and coronary heart disease. Population pharmacokinetic analysis of scientific trial information indicated a reduction in sildenafil clearance when co-administered with CYP3A4 inhibitors . Although no increased incidence of opposed occasions was noticed in these patients, when sildenafil is administered concomitantly with CYP3A4 inhibitors, a beginning dose of 25 mg ought to be thought-about. A double-blind, placebo-controlled train stress trial evaluated 144 patients with erectile dysfunction and persistent stable angina who frequently received anti-anginal medicinal products .

Studies with human platelets point out that sildenafil potentiates the antiaggregatory effect of sodium nitroprusside in vitro. There is not any safety info on the administration of sildenafil to patients with bleeding disorders or active peptic ulceration. Therefore sildenafil must be administered to these sufferers only after careful benefit-risk assessment. In the occasion of an erection that persists for longer than 4 sidena tablets hours, the affected person ought to seek instant medical help. Since April 2018 pharmacies can supply Viagra Connect with no prescription, though this is considerably more expensive. Viagra and generic sildenafil remain a prescription only drugs which can be distributed legally solely from registered pharmacies.

Generally, you must be sexually aroused for sildenafil to work and offer you an erection. Fast, discreet deliveryYour medication or test kit is dispatched by our pharmacy and delivered by Royal Mail. When sildenafil is taken with meals, the rate of absorption is lowered with a mean delay in tmax of 60 minutes and a imply reduction in Cmax of 29%. Any unused medicinal product or waste material sidena ought to be disposed of in accordance with native requirements. When sildenafil is taken with food, the rate of absorption is lowered with a imply delay in Tmax of 60 minutes and a imply reduction in Cmax of 29%. Sildenafil didn't affect the steady state pharmacokinetics of the HIV protease inhibitors, saquinavir and ritonavir, each of which are CYP3A4 substrates.

In the occasion of an erection that persists longer than 4 hours, the patient ought to seek quick medical help. If priapism just isn't treated immediately, penile tissue injury and everlasting lack of potency could outcome. In single dose volunteer research of doses as a lot sildenafil as 800mg, adverse reactions were much like those seen at decrease doses, however the incidence rates and severities were elevated. Doses of 200mg did not end in elevated efficacy but the incidence of adverse reactions was elevated.

Regorafenib   is a multi-kinase inhibitor used primarily for the treatment of cancer. It is particularly effective in targeting angiogenesis (the formation of new blood vessels), which plays a crucial role in cancer growth and metastasis. Below is a detailed overview of Regorafenib:

Mechanism of Action:

Regorafenib inhibits multiple protein kinases involved in tumor angiogenesis, oncogenesis, and the tumor microenvironment. Specifically, it targets:

VEGFR (Vascular Endothelial Growth Factor Receptor) – involved in blood vessel formation.

PDGFR (Platelet-Derived Growth Factor Receptor) – involved in the growth and survival of cells.

RAF kinases (including BRAF) – involved in cell proliferation and survival.

By blocking these pathways, Regorafenib reduces tumor growth and the spread of cancer.

Indications:

Regorafenib is used in the treatment of several cancers, including:

Colorectal Cancer: It is used in metastatic colorectal cancer (mCRC) that has progressed after standard therapy.

Gastrointestinal Stromal Tumors (GIST): It is prescribed for GIST after imatinib and sunitinib treatment have failed.

Hepatocellular Carcinoma (HCC): For patients with advanced liver cancer who have been previously treated with sorafenib.

Common Side Effects:

Fatigue

Hand-foot skin reaction (redness, swelling, pain in palms and soles)

Diarrhea

Hypertension (high blood pressure)

Nausea and vomiting

Abdominal pain

Decreased appetite

Weight loss

Serious Side Effects:

Liver toxicity: Regorafenib can lead to severe liver damage, including elevated liver enzymes, jaundice, and, in rare cases, liver failure.

Bleeding: Regorafenib can increase the risk of severe bleeding, especially in patients with cancer that has spread to the liver.

Cardiovascular complications: It can lead to high blood pressure and may increase the risk of heart attack or stroke.

Gastrointestinal perforation: A rare but potentially life-threatening complication.

Monitoring and Precautions:

Liver function should be monitored regularly because of the risk of liver toxicity.

Blood pressure should be checked frequently to detect any early signs of hypertension.

Skin reactions should be monitored closely, as they can affect the patient's quality of life.

Kidney function should also be assessed periodically, especially in patients at risk of kidney damage.

Pharmacokinetics:

Absorption: Regorafenib is well absorbed after oral administration but should be taken with a low-fat meal to ensure proper absorption.

Metabolism: The drug is metabolized in the liver primarily through CYP3A4, and its active metabolites also play a role in its efficacy.

Excretion: Regorafenib and its metabolites are excreted primarily through feces, with a small portion eliminated through urine.

InflaRx Initiates First-in-Human Study with Small Molecule C5aR Inhibitor INF904

InflaRx N.V.

Randomized, double-blind, placebo-controlled Phase I trial of orally administered complement inhibitor INF904 initiated

Study designed as single ascending dose to determine safety, tolerability and pharmacokinetics in healthy volunteers

Future development in complement-mediated chronic diseases

JENA, Germany, Nov. 09, 2022 (GLOBE NEWSWIRE) — InflaRx N.V. (Nasdaq: IFRX), a clinical-stage biopharmaceutical company developing anti-inflammatory therapeutics by targeting the complement system, today announced that it has dosed its first healthy volunteer in a randomized, double-blind, placebo-controlled Phase I trial of orally administered, small molecule C5aR inhibitor INF904. This single ascending dose Phase I trial aims to evaluate the safety, tolerability and pharmacokinetics of INF904 in healthy volunteers.

“Our preclinical studies with our new orally administered, small molecule C5aR inhibitor INF904 have shown potential for INF904 to inhibit C5a-induced signaling through its receptor C5aR. We are excited to enter clinical development of this new drug candidate,” said Renfeng Guo, M.D., Chief Scientific Officer and Founder of InflaRx. “INF904 is a promising addition to our pipeline of candidates controlling the terminal complement C5a / C5aR pathway. As an orally administered compound, we plan to study if INF904 is especially suitable for patients suffering from complement-mediated chronic autoimmune and inflammatory diseases requiring ongoing long-term treatment,” he added.

In the Phase I first-in-human trial, InflaRx plans to initially enroll approximately 62 healthy volunteers who will be randomly assigned to receive INF904 or placebo. The study will assess single ascending doses under fasted conditions. The main objective of the trial is to assess safety and tolerability. Secondary endpoints include several pharmacokinetic parameters. The effect of INF904 on C5a-induced downstream activity will also be explored.

Story continues

As reported in January 2022, INF904 showed anti-inflammatory therapeutic effects in several preclinical disease models and there were no obvious toxicological findings in investigational new drug (IND)-enabling (preclinical) studies, including required good laboratory practice (GLP) toxicity analyses. In these preclinical studies, oral INF904 showed higher plasma exposure in animals, including non-human primates, and improved neutrophil-inhibitory activity in a hamster model compared to a marketed C5aR inhibitor. Further, in contrast to the marketed C5aR inhibitor, in vitro experiments demonstrated that INF904 has substantially less inhibition of the cytochrome P450 3A4/5 (CYP3A4/5) enzymes, which play an important role in the metabolism of a variety of metabolites and drugs, including glucocorticoids. InflaRx plans to study INF904 for the treatment of complement-mediated, chronic autoimmune and inflammatory diseases where oral administration is the preferred choice for patients.

CIALIS and other erectile dysfunction treatments

The efficacy and safety of combining CIALIS with other PDE5 inhibitors or other treatments for erectile dysfunction have not been studied.

Patients should be informed not to use such combinations.

Lactose

시알리스 contains lactose. Patients with rare hereditary galactose intolerance, Lapp lactase deficiency, or glucose-galactose malabsorption syndrome should not take this medicine.

CIALIS Drug Interactions -

Interaction studies have been conducted with the 10 and/or 20 mg dose of tadalafil, as indicated below. With regard to the interaction studies where only the 10 mg dose was used, these do not make it possible to exclude the possibility of clinically relevant interactions at higher doses.

Effects of other substances on tadalafil

Cytochrome P450 inhibitors

Tadalafil is primarily metabolized by CYP3A4. In the presence of a selective inhibitor of CYP3A4, ketoconazole (200 mg daily), the exposure (AUC) to tadalafil (10 mg) is multiplied by 2 and the Cmax increased by 15% compared to the values ​​of AUC and C max observed with tadalafil alone. At a dose of 400 mg per day, ketoconazole multiplies the exposure (AUC) to tadalafil (20 mg) by 4 and increases the Cmax by 22%. Ritonavir, a protease inhibitor of CYP3A4, CYP2C9, CYP2C19, and CYP2D6 (200 mg twice daily), increases the exposure (AUC) of tadalafil (20 mg) by 2, with no change in Cmax. Although specific interactions have not been studied, other protease inhibitors, such as saquinavir, and other CYP3A4 inhibitors, such as erythromycin, clarithromycin, itraconazole, and grapefruit juice, should be co-administered.

administered with caution as they may increase tadalafil plasma concentrations (see section 4.4). The incidence of the undesirable effects mentioned under Undesirable effects could therefore be increased.

Carriers

The role of transporters (such as P-glycoprotein) in the distribution phase of tadalafil is not known. Thus, there is, therefore, a potential risk of drug interactions due to the inhibition of transporters.

Cytochrome P450 inducers

Rifampicin, an inducer of CYP3A4, reduces the AUC of tadalafil by 88% compared to the AUC determined for tadalafil alone (10 mg). This decrease may reduce the effectiveness of tadalafil; the value of this reduction is not known. A decrease in tadalafil plasma concentrations cannot be ruled out when combined with other CYP3A4 inducers, such as phenobarbital, phenytoin, and carbamazepine.

Effects of tadalafil on other drugs

Nitrates

Clinical studies have shown that tadalafil (5, 10, and 20 mg) increased the hypotensive effects of nitrates. Administration of 시알리스 to patients receiving nitrates in any form is therefore contraindicated (see section Contraindications). The results of a clinical study carried out on 150 patients who received daily doses of 20 mg of tadalafil for 7 days, and 0.4 mg of sublingual trinitrate at various times showed that this interaction lasted more than 24 hours and n was no longer detectable 48 hours after the last dose of tadalafil. Thus, in a patient taking CIALIS whatever the dose (2.5 mg - 20 mg), and in whom the administration of a nitrate derivative is deemed necessary for the vital prognosis, a minimum period of 48 hours after the last intake of 시알리스 must be respected, before administering a nitrated derivative. In this case, nitrates should only be administered under strict medical supervision including appropriate hemodynamic monitoring.
