Inclusion Criteria
- •Have a body mass index (BMI) ≥18 and ≤30 kg/m2 and weigh at least 50 kg and no more than 100 kg. Females of non-childbearing potential must be postmenopausal defined as amenorrhea for at least 12 months following cessation of all exogenous hormonal treatments and follicle stimulating hormone (FSH) levels in the postmenopausal range or documentation of irreversible surgical sterilization by hysterectomy, bilateraloophorectomy or bilateral salpingectomy but not tubal ligation
- •Females of childbearing potential must have a negative pregnancy test at screening, Day -1, and Day 14 and must not be lactating and use effective contraceptive methods to avoid pregnancy during the treatment period
- •Male healthy volunteers with a partner of childbearing potential must agree to avoid fathering a child, and refrain from donating sperm, from the first day of dosing until at least 3 months after last dose of the investigational product, and therefore be either sterile or agree to use approved methods of contraception
Exclusion Criteria
- •History of any clinically significant disease or disorder which, in the opinion of the principal investigator, may either put the healthy volunteer at risk because of participation in the study, or influence the results or the healthy volunteer's ability to participate in the study. History or presence of GI, hepatic or renal disease including GI surgery other than appendectomy or any other condition known to interfere with the absorption, distribution, metabolism or excretion of drugs. Loose stools (BSFS of 6 or 7) ≥2 days in the past 7 days before investigational product administration. Use of medications that are known to affect stool consistency and/or GI motility, including fiber supplements, anti-diarrheals, prokinetic drugs, enemas, probiotic medications or supplements, or salt or electrolyte supplements containing sodium, potassium, chloride, or bicarbonate formulations during the past 7 days before the investigational product administration. Use of any prescribed or non-prescribed medication including antacids, analgesics other than paracetamol/acetaminophen, herbal remedies, vitamins and minerals during the 2 weeks prior to the first administration of investigational product or longer if the medication has a long half-life. Use of drugs or substances with enzyme-inducing properties within 4 weeks prior to the first administration of investigational product.

Outcomes
Primary Outcomes
To evaluate the pharmacokinetics of midazolam when administered after AZD1722 by assessment of area under the concentration-time curve (AUC) and maximal plasma concentration (Cmax) of midazolam
Time Frame: Blood samples are collected predose, 0.25, 0.5, 1, 2, 3, 4, 6, 8, 10, 12, 15 and 24 hours post dose on Day 1 and Day 15
Change in plasma area under the concentration-time curve (AUC) and maximal plasma concentration (Cmax) of midazolam after AZD1722 administration
Secondary Outcomes
- To evaluate the pharmacokinetics of midazolam metabolites when administered after AZD1722 by assessment of area under the concentration-time curve (AUC) maximal plasma concentration (Cmax) of 1-OH-midazolam and 4-OH-midazolam(Blood samples are collected predose, 0.25, 0.5, 1, 2, 3, 4, 6, 8, 10, 12, 15 and 24 hours post dose on Day 1 and Day 15)
- • To evaluate the pharmacokinetics of the metabolites 1-OH-midazolam and 4-OH-midazolam when midazolam is administered after AZD1722 by assessment of AUC and Cmax of 1-OH-midazolam and 4-OH-midazolam(Blood samples are collected predose, 0.25, 0.5, 1, 2, 3, 4, 6, 8, 10, 12, 15 and 24 hours post dose on Day 1 and Day 15)
- To evaluate the pharmacodynamic outcomes of AZD1722 by assessment of how AZD1722 effects stool consistency and frequency(Stool frequency and stool consistency will be measured daily (Day -1 through Day 16))
- To evaluate the plasma concentrations of AZD1722(Blood samples are collected predose, 1, 2, 4 hours post morning dose on Day 15)
