Women of childbearing potential, (defined as women physiologically capable of becoming pregnant, unless they are using effective method of contraception during dosing of the investigational product) practicing any two acceptable methods of contraception. a.Oral or other (e.g., injection, patch or implant) hormonal contraception which has been used continuously for at least one month prior to the first dose of study medication Intrauterine device or intrauterine system 12. Male participants are eligible to participate if they agree to the following criteria during the intervention period and for at least three months after the last dose of study intervention: a. Must agree not to donate sperm for the purpose of reproduction. b. Must agree to use contraception / double barrier methods (e.g., condom and occlusive cap or condom and spermicidal agent) 13. Subject and the legally authorized representative (LAR) must demonstrate adequate decision â?? making ability in order to make an informed choice about participating in this study by providing written informed consent. Illiterate subjects can be considered when performed according to GCP, as well as regulations/guidance of DCGI. 14. Negative Hepatitis B &C, HIV 15.

Exclusion criteria

Exclusion criteria: 1.Subjects with known allergies, hypersensitivity, or intolerance to Risperidone, Paliperidone, heparin or to any excipients of study drug and contraindications to the use of Rispolept Consta® long-acting injection. 2.Subjects with uncontrolled hypertension (i.e., BP greater than 150/100 mm of Hg). 3.Subjects with significant orthostatic hypotension at screening or before check-in on day 1; average of two orthostatic hypotension measurements will be considered when there is drop in systolic blood pressure of 20 mm Hg or more or diastolic blood pressure of 10 mm Hg or more on standing from supine measurements. 4.Subjects with inadequate mass in the gluteal regions to receive intramuscular drug injection. 5.Institutionalized subjects 6.Subjects who are having concurrent primary psychiatric (other than schizophrenia) or neurological diagnosis, including Neuroleptic malignant syndrome (NMS), dementia related psychosis, organic mental disorder, tardive dyskinesia, mood disorders, Parkinsonâ??s disease, priapism, history or presence of epilepsy or other conditions that potentially lower the seizure threshold, history of cerebrovascular disease. 7. History or presence of uncontrolled diabetes mellitus. 8.History or presence of circumstances that may increase the risk of the occurrence of torsade de pointes and/or sudden death in association with the use of drugs that prolong the QTc interval, including: bradycardia, cardiac arrhythmias, hypokalemia or hypomagnesemia, concomitant use of other drugs that known to prolong the QTc interval (e.g. Class 1A (e.g., quinidine, procainamide) or Class III (e.g., amiodarone, sotalol) antiarrhythmic medications, antipsychotic medications (e.g., chlorpromazine, thioridazine), antibiotics (e.g., gatifloxacin, moxifloxacin), or any other class of medications known to prolong the QTc interval); and presence of prolonged QT interval at screening (QTc greater than 450 msec in male subject or QT cgreater than 470 msec in female subjects, QTc interval calculated with Bazettâ??s Formula: QTCorrected equal to (QT Interval / sqr (RR Interval) ? ? ? ? ?? equal to ? ? /â?? ? R Where QT is the QT interval and RR is the interval from the onset of the QRS complex to the onset of the next QRS complex. Note If the subject was on any of these drugs, sufficient wash out period (of at least 5 half-lives) must have elapsed since the last dose of such drug before the first dose of investigational medicinal product for the current study. 9. Subjects who are having Hyperprolactinemia greater than or equal to 200ng/mL or greater than 200ng/mL with associated clinical symptoms at screening. 10. Pregnant or lactating women. 11.
