Additional drugs found to be affected by grapefruit juice include, but are not limited to:

- Some statins, including atorvastatin (Lipitor), lovastatin (Mevacor) and simvastatin (Zocor, Simlup, Simcor, Simvacor)

- (In contrast, pravastatin (Pravachol), fluvastatin (Lescol) and rosuvastatin (Crestor) are unaffected by grapefruit.)

- Anti-arrhythmics including amiodarone (Cordarone), dronedarone (Multaq), quinidine (Quinidex, Cardioquin, Quinora), disopyramide (Norpace), propafenone (Rythmol) and carvedilol (Coreg)

- Amlodipine: Grapefruit increases the available amount of the drug in the blood stream, leading to an unpredictable increase in antihypertensive effects.

- Anti-migraine drugs ergotamine (Cafergot, Ergomar), amitriptyline (Elavil, Endep, Vanatrip) and nimodipine (Nimotop)

- Erectile dysfunction drugs sildenafil (Viagra), tadalafil (Cialis) and vardenafil (Levitra)

- Acetaminophen/paracetamol (Tylenol) concentrations were found to be increased in murinae blood by white and pink grapefruit juice, with the white juice acting faster. Interestingly, "the bioavailability of paracetamol was significantly reduced following multiple GFJ administration" in mice and rats. This suggests that repeated intake of grapefruit juice reduces the efficacy and bioavailability of acetaminophen/paracetamol in comparison to a single dose of grapefruit juice which conversely increases the efficacy and bioavailability of acetaminophen/paracetamol.

- Anthelmintics: Used for treating certain parasitic infections; includes praziquantel

- Apremilast (Otezla): Used to treat psoriasis.

- Buprenorphine: Metabolized into norbuprenorphine by CYP3A4

- Buspirone (Buspar): Grapefruit juice increased peak and AUC plasma concentrations of buspirone 4.3- and 9.2, respectively, in a randomized, 2-phase, ten-subject crossover study.

- Codeine is a prodrug that produces its analgesic properties following metabolism to morphine entirely by CYP2D6.

- Ciclosporin (cyclosporine, Neoral): Blood levels of ciclosporin are increased if taken with grapefruit juice, orange juice, or apple juice. A plausible mechanism involves the combined inhibition of enteric CYP3A4 and MDR1, which potentially leads to serious adverse events (e.g., nephrotoxicity). Blood levels of tacrolimus (Prograf) can also be equally affected for the same reason as ciclosporin, as both drugs are calcineurin inhibitors.

- Dihydropyridines including felodipine (Plendil), nicardipine (Cardene), nifedipine, nisoldipine (Sular) and nitrendipine (Bayotensin)

- Erlotinib (Tarceva)

- Exemestane, aromasin, and by extension all estrogen-like compounds and aromatase inhibitors which mimic estrogen in function will be increased in effect, causing increased estrogen retention and increased drug retention.

- Etoposide interferes with grapefruit, orange, and apple juices.

- Fexofenadine (Allegra)

- Fluvoxamine (Luvox, Faverin, Fevarin and Dumyrox)

- Imatinib (Gleevec): Although no formal studies with imatinib and grapefruit juice have been conducted, the fact that grapefruit juice is a known inhibitor of the CYP 3A4 suggests that co-administration may lead to increased imatinib plasma concentrations. Likewise, although no formal studies were conducted, co-administration of imatinib with another specific type of citrus juice called Seville orange juice (SOJ) may lead to increased imatinib plasma concentrations via inhibition of the CYP3A isoenzymes. Seville orange juice is not usually consumed as a juice because of its sour taste, but it is found in marmalade and other jams. Seville orange juice has been reported to be a possible inhibitor of CYP3A enzymes without affecting MDR1 when taken concomitantly with ciclosporin.

- Lamotrigine

- Levothyroxine (Eltroxin, Levoxyl, Synthroid): the absorption of levothyroxine is affected by grapefruit juice.

- Losartan (Cozaar)

- Methadone: Inhibits the metabolism of methadone and raises serum levels.

- Omeprazole (Losec, Prilosec)

- Oxycodone: grapefruit juice enhances the exposure to oral oxycodone. And a randomized, controlled trial 12 healthy volunteers ingested 200 mL of either grapefruit juice or water three times daily for five days. On the fourth day 10 mg of oxycodone hydrochloride were administered orally. Analgesic and behavioral effects were reported for 12 hours and plasma samples were analyzed for oxycodone metabolites for 48 hours. Grapefruit juice and increased the mean area under the oxycodone concentration-time curve (AUC(0-∞)) by 1.7 fold, the peak plasma concentration by 1.5-fold and the half-life of oxycodone by 1.2-fold as compared to water. The metabolite-to-parent ratios of noroxycodone and noroxymorphone decreased by 44% and 45% respectively. Oxymorphone AUC(0-∞) increased by 1.6-fold but the metabolite-to-parent ratio remained unchanged.

- Quetiapine (Seroquel)

- Repaglinide (Prandin)

- Tamoxifen (Nolvadex): Tamoxifen is metabolized by CYP2D6 into its active metabolite 4-hydroxytamoxifen. Grapefruit juice may potentially reduce the effectiveness of tamoxifen.

- Trazodone (Desyrel): Little or no interaction with grapefruit juice.

- Verapamil (Calan SR, Covera HS, Isoptin SR, Verelan)

- Warfarin (coumadin)

- Zolpidem (Ambien): Little or no interaction with grapefruit juice.

Apple juice, especially commercially produced products, interferes with the action of OATPs. This interference can decrease the absorption of a variety of commonly used medications, including beta blockers like atenolol, antibiotics like ciprofloxacin, and antihistamines like montelukast.

Apple juice has been implicated in interfering with etoposide, a chemotherapy drug, and cyclosporine, taken by transplant patients to prevent rejection of their new organs.

Following a declination or total extinction in response to a previously therapeutic dose of an antidepressant, the issue is clinically addressed as stemming from tolerance development. Several strategies are available, such as exploring drug options from a different drug class used to treat depression. The patient can also choose to switch to another SSRI (or MAOI, if applicable) while maintaining proportionate dose. If tolerance develops in a drug from the same class, the clinician may recommend a regular cycle consisting of all effective treatments within the SSRI or MAOI classes, in order to minimize transitional side effects while maximizing therapeutic efficacy.

Other options include increasing dose of the same medication, or supplementation with another antidepressant. Dual reuptake inhibitors, also known as tricyclic antidepressants have been shown to have lower rates of tachyphylaxis.

ADT tachyphylaxis specifically occurs in depressed patients using SSRIs and MAOIs. Currently, SSRIs are the preferred treatment for depression among clinicians, as MAOIs require the patient to avoid certain foods and other medications due to the potential for interactions capable of inducing dangerous side effects. Provided is a list of medications known to be subject to Poop-out.

The main treatment for acral erythema is discontinuation of the offending drug, and symptomatic treatment to provide analgesia, lessen edema, and prevent superinfection. However, the treatment for the underlying cancer of the patient must not be neglected. Often, the discontinued drug can be substituted with another cancer drug or cancer treatment.

Symptomatic treatment can include wound care, elevation, and pain medication. Corticosteroids and pyridoxine have also been used to relieve symptoms. Other studies do not support the conclusion.

A number of additional remedies are listed in recent medical literature. Among them henna and 10% uridine ointment which went through clinical trial.

mTOR inhibitors :

- Everolimus

- Temsirolimus

mTOR is a kinase enzyme inside the cell that regulates cell growth, proliferation, and survival. mTOR inhibitors lead to cell cycle arrest in the G1 phase and also inhibits tumor angiogenesis by reducing synthesis of VEGF.

A Phase II trial of Evorolimus on relapsed DLBCL patients showed a 30% Overall Response Rate (ORR).

The cooling of hands and feet during chemotherapy may help prevent PPE (Baack and Burgdorf, 1991; Zimmerman et al., 1995). Support for this and a variety of other approaches to treat or prevent acral erythema comes from small clinical studies, although none has been proven in a randomised controlled clinical trial of sufficient size.

Generally, acute myeloid leukemia is treated using chemotherapy consisting of an induction phase and consolidation phase (Dohner et al., 2009). Patients may also consider hematopoietic stem cell transplantation as a second mode of tackling the cancer. The most novel research is being done in tyrosine kinase inhibitors; however M2 acute myeloid leukemia treatment research involves molecules that inhibit the fusion oncoprotein AML1-ETO. Therefore, in terms of M2 subtype acute myeloid leukemia, the most prominent target is the abnormal AML1-ETO fusion protein. Similarly, chronic myeloid leukemia (CML) is comparable to acute myeloid leukemia M2 because it also forms a fusion oncoprotein – BCR-Abl. The developed tyrosine kinase inhibitor, imatinib mesylate, has had a tremendous effect on stopping cancer progression in the majority of chronic myeloid leukemia patients. BCR-Abl is constitutively active due chromosome translocation; therefore it over-phosphorylates the tyrosine kinase. Imatinib mesylate works to block BCR-Abl’s activity by blocking the active kinase domain (Fava et al., 2011).

Celastrol is a compound extracted from Tripterygium wilfordii that has anti-cancer properties. It was found to inhibit cell proliferation through the down regulation of AML1-ETO fusion oncoprotein. Celastrol inhibits the fusion oncoprotein by inducing mitochondrial instability and initiating caspase activity The decrease of AML1-ETO also results in lower levels of C-KIT kinases, Akt/PKB, STAT3, and Erk1/2 – all of which are involved in cell signaling and gene transcription (Yu et al., 2016).

Histone deacetylase inhibitors such as valproic acid (VPA), vorinostat, and all-trans retinoic acid (ATRA) are effective in targeting acute myeloid leukemia with the AML1-ETO fusion protein. The HDAC inhibitors are known to induce apoptosis through accumulation of DNA damage, inhibition of DNA repair, and activation of caspases. These inhibitors are extra sensitive to the fusion proteins. Vorinostat has been proven to cause a greater accumulation of DNA damage in fusion protein expressing cells and is directly correlated with the reduction of DNA repair enzymes (Garcia et al., 2008). Romidepsin, a drug in phase two clinical trials, has demonstrated higher efficacy in patients with AML1-ETO fusion protein leukemia (Odenike et al., 2008). Although many clinical evaluations have proven HDAC inhibitors have a promising effect on M2 subtype acute myeloid leukemia, it has not been approved as an official treatment.

In t(6;9) acute myeloid leukemia, FLT3-ITD and the DEK-NUP214 protein are potential targets for treatment. Sorafenib is a kinase inhibitor used as a treatment for kidney and liver cancer. The kinase inhibitor blocks serine-threonine kinase RAF-1 as well as FLT-ITD (Kindler, 2010). The drug has been proven to be effective in reducing FLT3-ITD overexpression (Metzelder et al., 2009). In patients with DEK-NUP214, it was found that the fusion oncoprotein caused an upregulation of mTORC1 (Sanden et al., 2013). Thus, a mTORC inhibitor could be a potential treatment.

Reversion of lipodystrophy does not occur after withdrawal of protease inhibitors.

Apoptosis is one of the major mechanisms of cell death targeted by cancer therapies. Reduced susceptibility to apoptosis increases the resistance of cancer cells to radiation and cytotoxic agents. B-cell lymphoma-2 (Bcl-2) family members create a balance between pro and anti-apoptotic proteins. Pro-apoptotic proteins include Bax and Bak. Anti-apoptotic proteins include Bcl-2, Bcl-X, Bcl-w, Mcl-1. When anti-apoptotic family members are overexpressed, apoptotic cell death becomes less likely.

- Oblimersen sodium (G3139, Genasense) targets BCL-2 mRNA

- ABT-737 (oral form navitoclax, ABT-263). A small molecule that targets anti-apoptotic Bcl-2 family proteins (Bcl-2, Bcl-X and Bcl-w). ABT-737 binds anti-apoptotic Bcl-2 proteins with an affinity two or three orders of magnitude more potent than previously reported compounds. High basal levels of Mcl-1 expression are associated with resistance to ABT-737. Combining ABT-737 with second agents that inactivate Mcl-1 may reduce this effect. ABT-737 has demonstrated single-agent efficacy against cell lines from lymphoid malignancies known to express high levels of Bcl-2, including DLBCL. It has also been found to be synergistic with proteasome inhibitors.

- Fenretinide. A synthetic retinoid that induces apoptosis of cancer cells and acts synergistically with chemotherapeutic drugs by triggering the activation of 12-Lox (12-lipoxygenase) leading to oxidative stress and apoptosis via the induction of the transcription factor Gadd153 and the Bcl-2-family member protein Bak.

GHRH analogs such as tesamorelin can be used to treat HIV-associated lipodystrophy.

Discontinuation syndrome is often prevented by taking medication as directed, and when discontinuing, doing so gradually. When discontinuing an antidepressant with a short half-life, switching to a drug with a longer half-life (e.g. fluoxetine or citalopram) and then discontinuing from that drug can decrease the likelihood and severity of symptoms.

Treatment is dependent on the severity of the discontinuation reaction and whether or not further antidepressant treatment is warranted. In cases where further antidepressant treatment is required then the only step required is restarting the antidepressant; this is usually the case following patient noncompliance with the drug. If antidepressants are no longer required, treatment depends on symptom severity. Mild reactions may only require reassurance. Moderate cases may require symptom management. If symptoms of discontinuation are severe, or do not respond to symptom management, the antidepressant can be reinstated and then withdrawn more cautiously. In rare but severe cases, hospitalization may be required.

While investigational drug therapies exist, no curative drug treatment exists for any of the MPDs. The goal of treatment for ET and PV is prevention of thrombohemorrhagic complications. The goal of treatment for MF is amelioration of anemia, splenomegaly, and other symptoms. Low-dose aspirin is effective in PV and ET. Tyrosine kinase inhibitors like imatinib have improved the prognosis of CML patients to near-normal life expectancy.

Recently, a "JAK2" inhibitor, namely ruxolitinib, has been approved for use in primary myelofibrosis. Trials of these inhibitors are in progress for the treatment of the other myeloproliferative neoplasms.

Epithelioid sarcoma (especially advanced stage, recurrent, or metastasized disease) has been shown to be resistant to traditional cancer therapies, necessitating further exploration of novel treatment methods and techniques. Because of the relatively poor response of epithelioid sarcoma to traditional cancer treatments (surgery, chemotherapy, and radiation), new treatment strategies are being looked to.

While capable of producing significantly improved responses compared with the action of imatinib, neither dasatinib nor nilotinib could overcome drug resistance caused by one particular mutation found to occur in the structure of BCR-ABL known as the T315I mutation (i.e. where the 315th amino acid is mutated from a threonine residue to an isoleucine residue). Two approaches were developed to the treatment of CML as a result:

In 2007, Chemgenex released results of an open-label Phase 2/3 study (CGX-635-CML-202) that investigated the use of a non BCR-ABL targeted agent omacetaxine, administered subcutaneously (under the skin) in patients who had failed with imatinib and exhibited T315I kinase domain mutation. This is a study which is ongoing through 2014. In September 2012, the FDA approved omacetaxine for the treatment of CML in the case of resistance to other chemotherapeutic agents.

Independently, ARIAD pharmaceuticals, adapting the chemical structures from first and second-generation TK inhibitors, arrived at a new pan-BCR-ABL inhibitor which showed (for the first time) efficacy against T315I, as well as all other known mutations of the oncoprotein. The drug, ponatinib, gained FDA approval in December 2012 for treatment of patients with resistant or intolerant CML. Just as with second generation TK inhibitors, early approval is being sought to extend the use of ponatinib to newly diagnosed CML also.

As one route to reducing TAMs CSF1R inhibitors have been developed as a possible cancer therapy and many are in early clinical trials. CSF1R inhibitors in clinical trials include : Pexidartinib, PLX7486, ARRY-382, JNJ-40346527, BLZ945, Emactuzumab, AMG820, IMC-CS4. (MCS110 is a CSF1 inhibitor)

Another CSF1R inhibitor that targets/depletes TAMs is Cabiralizumab (cabira; FPA-008) which is a monoclonal antibody and is in early clinical trials for metastatic pancreatic cancer.

To overcome imatinib resistance and to increase responsiveness to TK inhibitors, four novel agents were later developed. The first, dasatinib, blocks several further oncogenic proteins, in addition to more potent inhibition of the BCR-ABL protein, and was initially approved in 2007 by the US FDA to treat CML in patients who were either resistant to or intolerant of imatinib. A second new TK inhibitor, nilotinib, was also approved by the FDA for the same indication. In 2010, nilotinib and dasatinib were also approved for first-line therapy, making three drugs in this class available for treatment of newly diagnosed CML. In 2012, Radotinib joined the class of novel agents in the inhibition of the BCR-ABL protein and was approved in South Korea for patients resistant to or intolerant of imatinib. Bosutinib received US FDA and EU European Medicines Agency approval on September 4, 2012 and 27 March 2013 respectively for the treatment of adult patients with Philadelphia chromosome-positive (Ph+) chronic myelogenous leukemia (CML) with resistance, or intolerance to prior therapy.

NUT midline carcinoma is very resistant to standard chemotherapy treatments. The tumor may initially respond to therapy, and then rapid recurrence is experienced, followed by death. A multimodality approach to treatment is advocated, especially since most patients present with advanced disease. Treatment must be tailored to the individual patient, with several promising new targeted molecular therapies in clinical trials. Specific molecular targeted therapies (BET inhibitors and histone deacetylase inhibitors (HDACi)) may help to yield growth arrest of the neoplastic cells. Overall, there is a mean survival of 6–9 months.

Improvement or stabilization of the condition has been reported with topical and intralesional corticosteroids, antibiotics, hydroxychloroquine, topical and oral immunomodulators, tacrolimus, and most recently, 5-alpha-reductase inhibitors. In one study, the use of anti-androgens (finasteride or dutasteride) was associated with improvement in 47% and stabilization in 53% of patients

6-Pyruvoyltetrahydropterin synthase deficiency is an autosomal recessive disorder that causes malignant hyperphenylalaninemia due to tetrahydrobiopterin deficiency.

It belongs to the rare diseases. It is a recessive disorder that is accompanied by hyperphenylalaninemia. Commonly reported symptoms are initial truncal hypotonia, subsequent appendicular hypertonia, bradykinesia, cogwheel rigidity, generalized dystonia, and marked diurnal fluctuation. Other reported clinical features include difficulty in swallowing, oculogyric crises, somnolence, irritability, hyperthermia, and seizures. Chorea, athetosis, hypersalivation, rash with eczema, and sudden death have also been reported. Patients with mild phenotypes may deteriorate if given folate antagonists such as methotrexate, which can interfere with a salvage pathway through which dihydrobiopterin is converted into tetrahydrobiopterin via dihydrofolate reductase. Treatment options include substitution with neurotransmitter precursors (levodopa, 5-hydroxytryptophan), monoamine oxidase inhibitors, and tetrahydrobiopterin. Response to treatment is variable and the long-term and functional outcome is unknown. To provide a basis for improving the understanding of the epidemiology, genotype/phenotype correlation and outcome of these diseases their impact on the quality of life of patients, and for evaluating diagnostic and therapeutic strategies a patient registry was established by the noncommercial International Working Group on Neurotransmitter Related Disorders (iNTD).

Symptoms can last for more than 4 weeks and typically resolve within a day of restoring the medication.

Surgical resection of the tumor with wide margins remains the preferred method of treatment, and has shown the most success against the disease. Recently, limb-sparing surgery has been explored with moderate success.

In cases of advanced, recurrent, or metastasized disease, or if the tumor is inoperable, chemotherapy and radiation are the standard of care, although the overall success rates with these remains low.

PTLD may spontaneously regress on reduction or cessation of immunosuppressant medication, and can also be treated with addition of anti-viral therapy. In some cases it will progress to non-Hodgkin's lymphoma and may be fatal. A phase 2 study of adoptively transferred EBV-specific T cells demonstrated high efficacy with minimal toxicity.

Bisphosphonate therapy has been suggested as a first-line therapeutic option in many case reports and series.

Treatment with tumor necrosis factor alpha antagonists (TNF inhibitors) have been tried in few patients with limited success. Other drugs that are used in psoriatic arthritis, to which SAPHO syndrome is closely related, have also been used in this condition. They include NSAIDs, corticosteroids, sulfasalazine, methotrexate, ciclosporin and leflunomide.

Some patients have responded to antibiotics. The rationale for their use is that Propionibacterium acnes, a bacterium known for its role in acne, has been isolated from bone biopsies of SAPHO patients.

Although frequently employed to treat patients experiencing the cytokine storm associated with ARDS, corticosteroids and NSAIDs have been evaluated in clinical trials and have shown no effect on lung mechanics, gas exchange, or beneficial outcome in early established ARDS.
