Adalat CC

Generic name: nifedipine
Class: Calcium channel blocking agents

What is Adalat CC

Adalat CC is a calcium channel blocker. The structural formula of nifedipine is 3,5-pyridine dicarboxylic acid, 1,4-dihydro-2,6-dimethyl-4-(2-nitrophenyl)-dimethyl ester, C17H18N2O6nifedipine.

Nifedipine is a yellow crystalline molecule that is essentially water-insoluble but ethanol soluble. It has a 346.3 molecular weight.

Adalat CC uses

adalat orosAdalat CC is used to treat severe chest discomfort (angina) and excessive blood pressure (hypertension). High blood pressure burdens the heart and arteries. If it persists, the heart and arteries may be damaged. This can cause a stroke, heart failure, or kidney failure. High blood pressure raises the risk of a heart attack. Controlling blood pressure may help prevent these issues.

Adalat CC blocks calcium channels. It operates by altering calcium transport into heart and blood vessel cells. As a result, nifedipine relaxes blood arteries, increasing blood flow and decreasing heart workload.

Mention any unexpected or allergic reactions to this or other medicines to your doctor. Tell your doctor if you have allergies to foods, colors, preservatives, or animals. Read the ingredients carefully on non-prescription products.


No studies on the impact of Adalat CC on children’s ages have been done. No evidence of safety or efficacy.


No geriatric-specific issues have been shown in investigations to date, limiting the use of Adalat CC in the elderly. However, elderly people are more prone to age-related renal, liver, or heart problems, necessitating prudence and dose adjustments.

Studies on women show that this medicine presents no harm to the baby when used while nursing.

Medicine interactions

While many medicines should never be used together, others may be used even if an interaction is possible. In certain circumstances, your doctor may alter the dose or take other precautions.

Other health issues

Other medical issues may impact the use of this drug. Tell your doctor if you have any other health issues, especially:

Dosage and administration of Adalat CC

  • Dosage is to be adjusted according to the patient’s requirements. It is suggested that Adalat CC be taken orally each day with an empty stomach. Adalat CC is an extended-release dosage form, and tablets must be consumed in one piece, and not chewed or split. It is recommended that titration occurs over a period of 7-14 days beginning with 30 mg every day.
  • The titration process is based on the effectiveness of the therapy and its safety. The recommended dosage of maintenance is between 30 and 60 mg once a day. A dosage of more than 90 mg per day is not recommended.
  • If a cessation from Adalat CC is necessary, good clinical practice suggests the dose should be reduced slowly under the supervision of a doctor.
  • The co-administration of nifedipine and grapefruit juice should be avoided.
  • Be careful when administering Adalat CC to assure that the correct dosage is prescribed. 

Adalat CC side effects

In large controlled studies where adverse reactions were observed spontaneously, there were a lot of adverse reactions but were not usually serious and seldom required the stopping therapy or dose adjustments. The majority of them were the result of the vasodilator effect of Nifedipine capsules.

Adverse Effect Nifedipine capsules (%)
Placebo (%)
Dizziness, lightheadedness, and giddiness 27 15
The sensation of heat and flushing 25 8
Headache 23 20
Weakness 12 10
Nausea, heartburn 11 8
Muscle cramps, tremors 8 3
Peripheral edema 7 1
The mood can change, and anxiety may be present. 7 4
Palpitation 7 5
Dyspnea, cough, and wheezing 6 3
Nasal congestion Sore throat, nasal congestion 6 8

There’s also an extensive uncontrolled situation in more than 2100 patients across the United States. The majority of patients suffered from the vasospastic form of angina pectoris or were resistant to it and about half were also receiving treatment with beta-adrenergic blockers. The most frequently reported adverse incidents included:

Incidence Approximately 10%

  • Cardiovascular Edema in the peripheral region
  • Central Nervous System: Dizziness, or lightheadedness
  • Gastrointestinal: nausea
  • Systemic: headache, flushing as well as fatigue

Incidence Approximately 5%

  • CVS: Transient hypotension

Incidence 2% or Less

  • Cardiovascular: palpitation
  • Respiratory problems: chest and nasal congestion and shortness of breath
  • Gastrointestinal: diarrhea, constipation, cramps, flatulence
  • Musculoskeletal: inflammation, joint stiffness, muscle cramps
  • Central Nervous System shaking and nervousness, jitteriness blurred vision, sleep disturbances problems with balance
  • Other: dermatitis, pruritus, urticaria, fever, sweating, chills, sexual difficulties

Incidence Approximately 0.5%

  • Cardiovascular Syncope (mostly in the initial dose or an increase in dosage)
  • Eerythromelalgia

Incidence Less Than 0.5%

  • Hematologic: thrombocytopenia and anemia Leukopenia and purpura
  • Gastrointestinal: allergic hepatitis
  • The face and the thrombus: angioedema (mostly oropharyngeal edema that causes breathing difficulties in a handful of patients) gingival hyperplasia
  • CNS: depression, paranoid syndrome
  • Special Senses: temporary blindness at the top of plasma levels Tinnitus, transient blindness
  • Urogenital: polyuria, nocturia
  • Other symptoms include arthritis, ANA (+), Exfoliative Dermatitis, and Gynecomastia
  • Musculoskeletal: myalgia

Many of these side effects are thought to be related to dose. Peripheral edema was seen in approximately 25 percent of patients who took doses below 60 mg daily and in one patient with a dose of 120 mg daily or more. Hypotension transient, usually moderate to mild in severity, and rarely requiring the stopping therapy, occurred in one patient who took less than 60 mg/day and in one patient who took 120 mg daily or greater.

Very rarely, the introduction of Nifedipine capsules for therapy was related to an increase in pain in the angular region which could be due to hypotension. A temporary loss of vision unilaterally is also a possibility.

Furthermore, more severe adverse events were also observed that were not easily distinguished from the normal history of the illness in the patients. There is a chance that some or all of these events are connected. Myocardial infarction was reported in around 4 percent of patients, while the congestive heart condition or lung edema that occurred was approximately two percent. Conduction disturbances or arrhythmias occur in less than 0.5 percent of patients.

What if I missed dose

If you are missing a dose of this medicine make sure you take it as quickly as you are able. If it’s nearing the time to take the next dose, you can skip the missed dose, and go back to your usual dosage schedule. Do not take double doses.
