Ages Eligible for Study: 18 Years and above, Genders Eligible for Study: Both
- A male or female outpatient.
- Be at least 18 years of age and legal age of consent.
- Meet DSM-IV criteria for PD (with or without agoraphobia) for at least 3 months before study day 1.
- Have sufficient symptoms to require anxiolytic drug therapy.
- Have a score of * 4 on the Clinical Global Impressions Scale (CGI) severity of illness item.
- Have a minimum of 8 full-symptom panic attacks during the 4 weeks before the screening visit

- Women of childbearing potential must have a negative serum pregnancy test at screening. The signed informed consent should reflect an awareness of the stipulations concerning the use of contraception. A woman of childbearing potential is defined as one who is biologically capable of becoming pregnant. This includes women who are using contraceptives or whose sexual partners are either sterile or using contraceptives. Sexually active women participating in the study must use a medically acceptable form of contraception. Medically acceptable forms of contraception include oral contraceptives, injectable or implantable methods, intrauterine devices, or properly used barrier contraception. Additionally, the use of condoms is suggested as an adjunct to the methods previously addressed to protect against sexually transmitted diseases and to provide additional protection against accidental pregnancy.
- Treatment with venlafaxine (IR or ER) within 6 months of study day 1.
- Known hypersensitivity to venlafaxine (IR or ER) or related compounds.
- History or presence of any clinically important hepatic, renal, or other medical disease that might compromise the study or be detrimental to the patient (eg, clinically important cardiac arrhythmia, unstable diabetes, carcinoma [except basal cell epithelioma], uncontrolled hypertension).
- Clinically important abnormality on screening physical examination, vital signs, electrocardiogram (ECG), laboratory tests or urine drug screen.
- Pregnancy, lactation, plans to become pregnant during the study.
- Oral contraceptives that have been taken for less than 3 months before study day 1 if not using another medically accepted form of birth control.

- Any other clinically significant Axis I or Axis II disorder current or predominant within 6 months of study day 1 other than PD (with or without agoraphobia).
- Screening or baseline Hamilton Depression Rating Scale (HAM-D) score * 18.

- Acutely suicidal to such a degree that precautions against suicide must be employed.
- Urine drug screen positive for a drug of abuse.

- Cognitive behavioral therapy within 30 days of study day 1.
- Introduction or change in intensity of formal psychotherapy (regularly scheduled sessions employing specific techniques) within 60 days of study day 1.
- Electroconvulsive therapy (ECT) within 6 months of study day 1.
