Drug interactions
Moderate drug interactions
Moderate:
sildenafil sotagliflozin
Applies to: sildenafil and Inpefa (sotagliflozin)
Monitor
Sodium-glucose co-transporter 2 (SGLT-2) inhibitors may potentiate the hypotensive effects of diuretics, antihypertensive agents, vasodilators, or agents with hypotensive properties. Inhibition of glucose and sodium co-transport produces mild diuresis and transient natriuresis, resulting in intravascular volume contraction. Volume depletion-related adverse reactions including hypotension, postural dizziness, orthostatic hypotension, syncope, and dehydration can occur after initiating treatment with SGLT-2 inhibitors, and the risk may be increased with concomitant use of other agents that can lower blood pressure.
Management
Caution is advised if SGLT-2 inhibitors are coadministered with diuretics and/or agents with hypotensive properties, particularly in the elderly and patients with impaired renal function. Prior to initiating SGLT-2 inhibitors, volume status should be assessed and corrected, if necessary. Clinical and laboratory monitoring are recommended during therapy, including electrolytes, fluid status, renal function, and blood pressure. If volume depletion occurs, treatment with SGLT-2 inhibitors should be interrupted until the condition is corrected.

Food/lifestyle interactions
Moderate food/lifestyle interactions
Moderate:
sildenafil Food/Lifestyle
Applies to: sildenafil
Generally avoid
Coadministration with grapefruit juice may slightly increase the oral bioavailability and delay the onset of action of sildenafil. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruits. In a randomized, crossover study with 24 healthy male volunteers, ingestion of 250 mL of grapefruit juice one hour before and concurrently with a 50 mg dose of sildenafil increased the mean area under the plasma concentration-time curve (AUC) of sildenafil and its pharmacologically active N-desmethyl metabolite by 23% and 24%, respectively, compared to water. Peak plasma concentrations (Cmax) were unaltered, but the time to reach sildenafil Cmax was prolonged by 0.25 hour. The observed increase in sildenafil bioavailability is unlikely to be of clinical significance in most individuals. However, pharmacokinetic interactions involving grapefruit juice are often subject to a high degree of interpatient variability and may be significant in the occasional susceptible patient. Indeed, one subject in the study had a 2.6-fold increase in sildenafil concentrations.
Management
It may be advisable to avoid administration of sildenafil with grapefruit juice to prevent potential toxicity and delay in onset of action.

Moderate:
sotagliflozin Food/Lifestyle
Applies to: Inpefa (sotagliflozin)
Adjust dosing interval
Coadministration with a high-caloric meal may increase the bioavailability of sotagliflozin. When coadministered with a high-caloric breakfast, sotagliflozin peak plasma concentration (Cmax) and systemic exposure (AUC) increased by 149% and 50%, respectively, compared to fasting conditions. Multiple sotagliflozin doses (400 mg) administered immediately before breakfast, 30 minutes before breakfast, and 1 hour before breakfast in healthy subjects showed a consistent effect on urine glucose excretion, insulin, and postprandial glucose across all dose schedules.
Generally avoid
Alcohol may cause hypoglycemia or hyperglycemia in patients with diabetes. Hypoglycemia most frequently occurs during acute consumption of alcohol. Even modest amounts can lower blood sugar significantly, especially when the alcohol is ingested on an empty stomach or following exercise. The mechanism involves inhibition of both gluconeogenesis as well as the counter-regulatory response to hypoglycemia. Episodes of hypoglycemia may last for 8 to 12 hours after ethanol ingestion. By contrast, chronic alcohol abuse can cause impaired glucose tolerance and hyperglycemia. Moderate alcohol consumption generally does not affect blood glucose levels in patients with well controlled diabetes.
Management
Sotagliflozin should be administered no more than 1 hour before the first meal of the day. Patients with diabetes should avoid consuming alcohol if their blood glucose is not well controlled, or if they have hypertriglyceridemia, neuropathy, or pancreatitis. Patients with well controlled diabetes should limit their alcohol intake to one drink daily for women and two drinks daily for men (1 drink = 5 oz wine, 12 oz beer, or 1.5 oz distilled spirits) in conjunction with their normal meal plan. Alcohol should not be consumed on an empty stomach or following exercise.

Phosphodiesterase 5 (PDE-5) inhibitors are cleared predominantly by hepatic metabolism. The pharmacokinetic disposition of these agents has not been assessed in patients with severe hepatic impairment. No dosage modification is recommended for patients with mild to moderate hepatic impairment, however, therapy with these agents should not be administered to patients with severe hepatic impairment. In patients with mild hepatic impairment a lower dose of these agents should be used as initial therapy.
Myeloproliferative Disorders
Moderate:
sildenafil
Sildenafil has a moderate potential interaction with Myeloproliferative Disorders.
Prolonged erection greater than 4 hours and priapism (painful erections greater than 6 hours) have been reported during treatment with phosphodiesterase-5 (PDE 5) inhibitors. Priapism may result in penile tissue damage and permanent loss of potency if not treated promptly. These agents should be used cautiously in patients with conditions that may predispose them to priapism such as sickle cell anemia, multiple myeloma, or leukemia, and those with anatomical deformation of the penis (such as angulation, cavernosal fibrosis, or Peyronie's disease). If an erection persists longer than 4 hours, the patient should seek immediate medical assistance.
Optic Nerve Disorder
Moderate:
sildenafil
Sildenafil has a moderate potential interaction with Optic Nerve Disorder.
Sildenafil for the treatment of erectile dysfunction (ED) should be used with caution and only if the benefit outweighs the risk in patients with a history of non-arteritic anterior ischemic optic neuropathy (NAION) or with retinitis pigmentosa. Use of sildenafil for the treatment of pulmonary arterial hypertension is not recommended in patients with retinitis pigmentosa. Advise patients to seek immediate medical attention in the event of a sudden loss of vision in one or both eyes while taking sildenafil; patients taking sildenafil for ED should immediately stop treatment. Most patients who developed NAION during therapy with sildenafil had underlying anatomic or vascular risk factors, including low cup to disc ratio ("crowded disc").

Renal Dysfunction
Major:
Inpefa
The sotagliflozin in Inpefa has a major potential interaction with Renal Dysfunction.
The glucose lowering effects of sodium-glucose cotransporter 2 (SGLT2) inhibitors are decreased in patients with worsening renal function. Additionally, patients with impaired renal function (estimated GFR less than 60 mL/min/1.73 m2), older adult patients, and patients on loop diuretics may be more likely to experience adverse reactions related to volume depletion such as hypotension and acute kidney injury during therapy. Renal function should be evaluated prior to treatment initiation and monitored regularly in at-risk patients. Volume status should be assessed and volume depletion corrected before initiating therapy. The use of SGLT2 inhibitors in patients undergoing dialysis is either contraindicated or not recommended. The manufacturer product information should be consulted for contraindications and indication specific renal dosing.
Moderate:
Inpefa
The sotagliflozin in Inpefa has a moderate potential interaction with Renal Dysfunction.
Sodium-glucose cotransporter 2 (SGLT2) inhibitors cause intravascular volume contraction which may lead to symptomatic hypotension after treatment initiation, especially in older adult patients, patients with impaired renal function, patients with low systolic blood pressure, or those using diuretics.
